Per-resolution-level management layer +- **nvimgcodec_tiff_parser.cpp**: Metadata extraction layer +- **nvimgcodec_decoder.cpp**: Image decoding layer + +### 2. **Separation of Concerns** +- All nvImageCodec API calls isolated to `nvimgcodec_*` files +- TIFF-level logic (vendor detection, metadata) in `tiff.cpp` +- IFD-level logic (tile management, region reading) in `ifd.cpp` + +### 3. **Singleton Pattern** +- `NvImageCodecTiffParserManager::instance()` provides shared nvImageCodec instance +- Ensures all components use the same instance/decoders +- Prevents segfaults from mixed instances + +### 4. **RAII Resource Management** +- All nvImageCodec resources use RAII wrappers: + - `UniqueCodeStream` for code streams + - `UniqueImage` for image objects + - `UniqueFuture` for decode futures + - `DecodeBuffer` for CPU/GPU buffers + +### 5. **Data Flow** +- Metadata flows: `nvImageCodec → TiffFileParser → IfdInfo → IFD` +- Decode requests flow: `TIFF → IFD → decode_ifd_region_nvimgcodec` +- Decoded data flows: `nvImageCodec → decode buffer → IFD → TIFF → User` + +--- + +## Summary + +This architecture provides: +- **Clean abstraction** - nvImageCodec details isolated from TIFF logic +- **Extensibility** - Easy to add new vendor formats or codecs +- **Performance** - Direct ROI decoding without tile-based fallback +- **Safety** - RAII management prevents resource leaks +- **Maintainability** - Clear separation of responsibilities + +The flow ensures that: +1. Files are parsed once during `TIFF::open()` +2. Metadata is cached in `IfdInfo` structs +3. Decoding uses the most efficient path (ROI decode when available) +4.

Is `TIFF::kUseLibTiff` flag set? Remove it. +2. Does `is_read_optimizable()` return false? Check compression/format support. + +**Solution**: Use supported formats (tiled, RGB/YCbCr, supported codecs) + +### Problem: Out of memory errors + +**Symptoms**: cudaMalloc or malloc failures + +**Causes**: +1. Large ROI without pre-allocated buffer +2. Cache size too large +3. Batch size too large for GPU memory + +**Solutions**: +1. Pre-allocate output buffer: `request->buf->data = pre_allocated_buffer` +2. Reduce cache size in configuration +3. Reduce batch size or use CPU device + +### Problem: Segmentation fault + +**Common Causes**: +1. IFD outlives TIFF (dangling `nvimgcodec_sub_stream_` reference) +2. Double-free of nvImageCodec streams +3. Null pointer access when nvImageCodec unavailable + +**Prevention**: +1. Ensure TIFF object lifetime exceeds all IFD objects +2.

It provides centralized initialization, error handling, and access control for the nvImageCodec library within the cuslide2 codebase. The implementation carefully follows both modern C++ best practices and nvImageCodec's API requirements, while including workarounds for known issues with library cleanup during process shutdown. - diff --git a/nvimgcodec_tiff_parser_documentation.md b/nvimgcodec_tiff_parser_documentation.md deleted file mode 100644 index 108e47f1a..000000000 --- a/nvimgcodec_tiff_parser_documentation.md +++ /dev/null @@ -1,2091 +0,0 @@ -# nvImageCodec TIFF Parser - Line-by-Line Documentation - -## Overview - -The TIFF Parser provides a high-level interface for parsing and decoding TIFF files using nvImageCodec's file-level API.

Is nvImageCodec installed? Check `nvimgcodec_parser_` initialization -2. Is request multi-location or multi-batch? (Fast path requires single location/batch) -3. Is codec supported? (Only JPEG, JPEG2000 have fast path) - -**Solution**: Use single-location requests, ensure nvImageCodec is available - -### Problem: RGBA output instead of RGB - -**Symptoms**: 4 channels instead of 3, slow performance - -**Cause**: Slow path (libtiff) is being used - -**Checks**: -1. Is `TIFF::kUseLibTiff` flag set? Remove it. -2. Does `is_read_optimizable()` return false? Check compression/format support. - -**Solution**: Use supported formats (tiled, RGB/YCbCr, supported codecs) - -### Problem: Out of memory errors - -**Symptoms**: cudaMalloc or malloc failures - -**Causes**: -1. Large ROI without pre-allocated buffer -2. Cache size too large -3. Batch size too large for GPU memory - -**Solutions**: -1. Pre-allocate output buffer: `request->buf->data = pre_allocated_buffer` -2. Reduce cache size in configuration -3. Reduce batch size or use CPU device - -### Problem: Segmentation fault - -**Common Causes**: -1. IFD outlives TIFF (dangling `nvimgcodec_sub_stream_` reference) -2. Double-free of nvImageCodec streams -3. Null pointer access when nvImageCodec unavailable - -**Prevention**: -1. Ensure TIFF object lifetime exceeds all IFD objects -2. Review destructor logic for nvImageCodec resources -3. Always null-check `nvimgcodec_parser_` before use - ---- - -## Future Enhancements - -### Potential Improvements - -1. **ROI Decoding for All Codecs** - - Extend ROI support to LZW, DEFLATE - - Implement tile-intersection optimization - -2. **Better Multi-Location Fast Path** - - Batch multiple ROIs in single nvImageCodec call - - Reduce overhead for small patches - -3. **Adaptive Fast Path Selection** - - Profile ROI size vs. tile overhead - - Automatically choose best path based on request - -4. **Unified Decoder Interface** - - Abstract codec-specific logic - - Pluggable decoder architecture - -5. **Better Error Recovery** - - Partial decode on tile corruption - - Retry logic for transient GPU errors - ---- - -## Conclusion - -The TIFF/IFD integration with nvImageCodec provides: - -✅ **Dual-mode operation**: GPU-accelerated fast path + CPU fallback -✅ **Flexible decoding**: ROI, tile-based, batch processing -✅ **Multi-codec support**: JPEG, JPEG2000, LZW, DEFLATE, etc. -✅ **Performance optimization**: Caching, threading, GPU batch decode -✅ **Graceful degradation**: Works even without nvImageCodec - -**Key Takeaway**: The architecture prioritizes **performance** (GPU fast path) while ensuring **reliability** (CPU fallbacks), making it suitable for both interactive viewing and high-throughput training workloads. - From

---- - -## Architecture Principles - -### 1. **Layered Design** -- **tiff.cpp**: High-level orchestration layer -- **ifd.cpp**: Per-resolution-level management layer -- **nvimgcodec_tiff_parser.cpp**: Metadata extraction layer -- **nvimgcodec_decoder.cpp**: Image decoding layer - -### 2. **Separation of Concerns** -- All nvImageCodec API calls isolated to `nvimgcodec_*` files -- TIFF-level logic (vendor detection, metadata) in `tiff.cpp` -- IFD-level logic (tile management, region reading) in `ifd.cpp` - -### 3. **Singleton Pattern** -- `NvImageCodecTiffParserManager::instance()` provides shared nvImageCodec instance -- Ensures all components use the same instance/decoders -- Prevents segfaults from mixed instances - -### 4. **RAII Resource Management** -- All nvImageCodec resources use RAII wrappers: - - `UniqueCodeStream` for code streams - - `UniqueImage` for image objects - - `UniqueFuture` for decode futures - - `DecodeBuffer` for CPU/GPU buffers - -### 5. **Data Flow** -- Metadata flows: `nvImageCodec → TiffFileParser → IfdInfo → IFD` -- Decode requests flow: `TIFF → IFD → decode_ifd_region_nvimgcodec` -- Decoded data flows: `nvImageCodec → decode buffer → IFD → TIFF → User` - ---- - -## Summary - -This architecture provides: -- **Clean abstraction** - nvImageCodec details isolated from TIFF logic -- **Extensibility** - Easy to add new vendor formats or codecs -- **Performance** - Direct ROI decoding without tile-based fallback -- **Safety** - RAII management prevents resource leaks -- **Maintainability** - Clear separation of responsibilities - -The flow ensures that: -1. Files are parsed once during `TIFF::open()` -2. Metadata is cached in `IfdInfo` structs -3. Decoding uses the most efficient path (ROI decode when available) -4.

-- **Legacy path**: Tile-by-tile decode (lines 526-912) - - Deprecated, mostly removed - - Throws error on cache miss - - Only for boundary cases - -### 3. **Borrowed Pointer Pattern** -- `nvimgcodec_sub_stream_` is **NOT owned** by IFD -- Borrowed from `TiffFileParser::ifd_infos_` -- Set to `nullptr` in destructor (no cleanup) -- Prevents double-free crashes - -### 4. **Variant-Based Metadata** -- Uses `TiffFileParser::get_tiff_tag()` for metadata extraction -- Returns strings (converted from typed variants) -- Type-safe storage, simple API - -### 5. **Caching Strategy** -- Tile cache using `ImageCache` -- Hash-based lookup (`ifd_hash_value ^ tile_index`) -- Cache miss → throw error (was: decode with CPU) -

-**Behind the scenes:** -- Variant stores: `TiffTagValue = std::string("Aperio Image Library v1.0.0")` -- `get_tiff_tag()` returns: `"Aperio Image Library v1.0.0"` - ---- - -### 2. **Numeric Tags** (TileWidth, TileLength) -

---- - -### 3. **Binary Tags** (JPEGTables) - -Binary data tags are stored as `std::vector` and summarized as strings: - -```cpp -std::string jpeg_tables = tiff->nvimgcodec_parser_->get_tiff_tag(index, "JPEGTables"); -if (!jpeg_tables.empty()) { - // JPEGTables exist (abbreviated JPEG) -} -``` - -**Behind the scenes:** -- Variant stores: `TiffTagValue = std::vector{...binary data...}` -- `get_tiff_tag()` returns: `"[514 bytes]"` (summary format) -- User checks: If not empty, binary data exists -

---- - -## Summary - -The variant-based TIFF tag system provides a **clean separation of concerns**: - -1. **TiffFileParser** handles: - - nvImageCodec API interaction - - Type conversion (bytes → variant) - - Storage in typed map - -2. **Consumers (IFD, TIFF)** handle: - - Simple string-based retrieval via `get_tiff_tag()` - - Type conversion for specific use cases (string → uint32_t, etc.) - - Business logic - -This design keeps the complexity contained in the parser while providing a simple, robust API for the rest of the codebase. - diff --git a/VARIANT_TIFF_TAG_IMPLEMENTATION.md b/VARIANT_TIFF_TAG_IMPLEMENTATION.md deleted file mode 100644 index 60400a9b4..000000000 --- a/VARIANT_TIFF_TAG_IMPLEMENTATION.md +++ /dev/null @@ -1,530 +0,0 @@ -# Variant-Based TIFF Tag Storage Implementation - -## Overview - -This document describes the implementation of a **fully type-safe, extensible variant system** for storing TIFF tag values extracted from the nvImageCodec metadata API. This design replaces fragile string-based parsing with strongly-typed storage, providing type safety, memory efficiency, and extensibility. - -## Architecture - -### 1. Type Definition: `TiffTagValue` Variant - -A comprehensive variant type supporting **all TIFF data types** defined in `nvimgcodec_tiff_parser.h`: - -```cpp -using TiffTagValue = std::variant< - std::monostate, // Empty/unset state - std::string, // ASCII strings - int8_t, // SBYTE - uint8_t, // BYTE - int16_t, // SSHORT - uint16_t, // SHORT - int32_t, // SLONG - uint32_t, // LONG - int64_t, // SLONG8 - uint64_t, // LONG8/IFD8 - float, // FLOAT - double, // DOUBLE - std::vector, // Binary data (JPEGTables, UNDEFINED) - std::vector, // Arrays of SHORT (BitsPerSample, etc.) - std::vector, // Arrays of LONG (SubIFD offsets, etc.) - std::vector, // Arrays of LONG8 (BigTIFF offsets) - std::vector, // Arrays of FLOAT values - std::vector // Arrays of DOUBLE values ->; -``` - -**Key Features:** -- **17 different types** covering all TIFF tag value types -- **Scalar types**: All signed/unsigned integers (8/16/32/64-bit), floats, doubles -- **Vector types**: For multi-value tags (arrays) -- **Binary data**: `std::vector` for JPEGTables, UNDEFINED types -- **Empty state**: `std::monostate` for tags not found or extraction failures - ---- - -## 2. Storage Container - -Each `IfdInfo` structure stores TIFF tags in an unordered map: - -```cpp -struct IfdInfo { - // ... other fields ... - - // nvImageCodec 0.7.0: Individual TIFF tag storage with typed values - // tag_name -> TiffTagValue (variant with typed storage) - std::unordered_map tiff_tags; -}; -``` - -- **Key**: Tag name as string (e.g., `"SUBFILETYPE"`, `"ImageDescription"`, `"TileWidth"`) -- **Value**: `TiffTagValue` variant holding the typed data - ---- - -## 3. Extraction Logic: Type Conversion from nvImageCodec - -### Main Extraction Function: `extract_tiff_tags()` - -Located in `nvimgcodec_tiff_parser.cpp`, this function: - -1. Queries nvImageCodec for available TIFF tags using `NVIMGCODEC_METADATA_KIND_TIFF_TAG` -2. Allocates buffers based on reported sizes -3. Retrieves tag metadata with type information -4. Converts raw bytes to typed variant values - -### Type Mapping Switch Statement - -The core conversion logic maps nvImageCodec metadata types to C++ variant types: - -```cpp -switch (metadata.value_type) -{ - case NVIMGCODEC_METADATA_VALUE_TYPE_ASCII: - // ASCII string - remove trailing nulls - std::string str_val; - str_val.assign(reinterpret_cast(buffer.data()), metadata.buffer_size); - while (!str_val.empty() && str_val.back() == '\0') - str_val.pop_back(); - if (!str_val.empty()) - tag_value = std::move(str_val); - break; - - case NVIMGCODEC_METADATA_VALUE_TYPE_SHORT: - // uint16_t: single value or array - extract_single_value(buffer, metadata.value_count, tag_value) || - extract_value_array(buffer, metadata.value_count, tag_value); - break; - - case NVIMGCODEC_METADATA_VALUE_TYPE_LONG: - // uint32_t: single value or array - extract_single_value(buffer, metadata.value_count, tag_value) || - extract_value_array(buffer, metadata.value_count, tag_value); - break; - - case NVIMGCODEC_METADATA_VALUE_TYPE_BYTE: - if (metadata.value_count == 1) - tag_value = buffer[0]; // Single byte - else - tag_value = std::vector(buffer.begin(), buffer.begin() + metadata.buffer_size); - break; - - case NVIMGCODEC_METADATA_VALUE_TYPE_LONG8: - case NVIMGCODEC_METADATA_VALUE_TYPE_IFD8: - // uint64_t: single value or array (BigTIFF support) - extract_single_value(buffer, metadata.value_count, tag_value) || - extract_value_array(buffer, metadata.value_count, tag_value); - break; - - case NVIMGCODEC_METADATA_VALUE_TYPE_FLOAT: - extract_single_value(buffer, metadata.value_count, tag_value) || - extract_value_array(buffer, metadata.value_count, tag_value); - break; - - case NVIMGCODEC_METADATA_VALUE_TYPE_DOUBLE: - extract_single_value(buffer, metadata.value_count, tag_value) || - extract_value_array(buffer, metadata.value_count, tag_value); - break; - - case NVIMGCODEC_METADATA_VALUE_TYPE_RATIONAL: - // Convert to string format "numerator/denominator" - if (metadata.value_count == 1 && metadata.buffer_size >= 8) { - uint32_t num = *reinterpret_cast(buffer.data()); - uint32_t den = *reinterpret_cast(buffer.data() + 4); - if (den != 0) - tag_value = fmt::format("{}/{}", num, den); - else - tag_value = std::to_string(num); - } - break; - - case NVIMGCODEC_METADATA_VALUE_TYPE_UNDEFINED: - // Binary/unknown data - store as vector - tag_value = std::vector(buffer.begin(), buffer.begin() + metadata.buffer_size); - break; - - // ... additional cases for SBYTE, SSHORT, SLONG, SLONG8, SRATIONAL, etc. -} - -// Store in IFD's tag map if extraction succeeded -if (!std::holds_alternative(tag_value)) { - ifd_info.tiff_tags[tag_name] = std::move(tag_value); -} -``` - -### Key Extraction Strategy - -1. **Single vs Array Detection**: Automatically distinguishes based on `metadata.value_count` - - `value_count == 1` → Store as scalar (e.g., `uint16_t`) - - `value_count > 1` → Store as vector (e.g., `std::vector`) - -2. **Rational Types**: Converted to human-readable string format (`"num/den"`) - -3. **Binary Safety**: Configurable size limit (`max_binary_tag_size_`) prevents memory bloat from large binary blobs - -4. **Move Semantics**: Uses `std::move()` to avoid unnecessary copies - ---- - -## 4. Template Helpers for Type-Safe Extraction - -Two template functions handle the **single value vs array** pattern elegantly: - -### Single Value Extraction - -```cpp -template -static bool extract_single_value(const std::vector& buffer, - int value_count, - TiffTagValue& out_value) -{ - if (value_count == 1) - { - T val = *reinterpret_cast(buffer.data()); - out_value = val; - return true; - } - return false; -} -``` - -### Array Extraction - -```cpp -template -static bool extract_value_array(const std::vector& buffer, - int value_count, - TiffTagValue& out_value) -{ - if (value_count > 1) - { - const T* vals = reinterpret_cast(buffer.data()); - out_value = std::vector(vals, vals + value_count); - return true; - } - return false; -} -``` - -### Usage Pattern - -The templates are used with logical OR for clean fallback: - -```cpp -// Try single value first, fall back to array if value_count > 1 -extract_single_value(buffer, value_count, tag_value) || -extract_value_array(buffer, value_count, tag_value); -``` - -This approach: -- Returns `true` and populates `tag_value` on success -- Automatically selects the correct storage type (scalar vs vector) -- Compiles to optimal code via template instantiation - ---- - -## 5. Retrieval and Conversion to String - -### Visitor Pattern for Type-Safe Conversion - -The `tiff_tag_value_to_string()` helper uses `std::visit` for compile-time type dispatch: - -```cpp -static std::string tiff_tag_value_to_string(const TiffTagValue& value) -{ - return std::visit([](const auto& v) -> std::string { - using T = std::decay_t; - - if constexpr (std::is_same_v) - { - return ""; // Empty/unset - } - else if constexpr (std::is_same_v) - { - return v; // Already a string - } - else if constexpr (std::is_same_v>) - { - return fmt::format("[{} bytes]", v.size()); // Binary data summary - } - else if constexpr (std::is_same_v>) - { - // Array: show first 10 elements, truncate with "..." - std::string result; - for (size_t i = 0; i < v.size() && i < 10; ++i) - { - if (i > 0) result += ","; - result += std::to_string(v[i]); - } - if (v.size() > 10) result += ",..."; - return result; - } - else if constexpr (std::is_same_v || std::is_same_v) - { - return fmt::format("{}", v); - } - else - { - return std::to_string(v); // Fallback for all integer types - } - }, value); -} -``` - -**Features:** -- **Compile-time dispatch**: `if constexpr` eliminates runtime overhead -- **Array truncation**: Shows first 10 elements for readability -- **Binary summaries**: Large binary data shows `"[1024 bytes]"` instead of dumping raw data -- **Type-safe**: Compiler ensures all variant types are handled - ---- - -## 6. Public API for Tag Retrieval - -Simple string-based interface in `TiffFileParser`: - -```cpp -std::string TiffFileParser::get_tiff_tag(uint32_t ifd_index, const std::string& tag_name) const -{ - if (ifd_index >= ifd_infos_.size()) - return ""; - - auto it = ifd_infos_[ifd_index].tiff_tags.find(tag_name); - if (it != ifd_infos_[ifd_index].tiff_tags.end()) - return tiff_tag_value_to_string(it->second); - - return ""; -} -``` - -### Usage Example (from `tiff/ifd.cpp`) - -```cpp -// Extract metadata from TIFF tags -software_ = tiff->nvimgcodec_parser_->get_tiff_tag(index, "Software"); -model_ = tiff->nvimgcodec_parser_->get_tiff_tag(index, "Model"); - -std::string tile_w_str = tiff->nvimgcodec_parser_->get_tiff_tag(index, "TileWidth"); -std::string tile_h_str = tiff->nvimgcodec_parser_->get_tiff_tag(index, "TileLength"); - -if (!tile_w_str.empty() && !tile_h_str.empty()) { - tile_width_ = std::stoul(tile_w_str); - tile_height_ = std::stoul(tile_h_str); -} -``` - ---- - -## Design Benefits - -### 1. Type Safety -- Compiler enforces correct type handling at compile time -- No runtime type confusion or casting errors -- `std::variant` provides exhaustive type checking - -### 2. Memory Efficiency -- No redundant string parsing or conversions -- Direct binary-to-typed storage -- Move semantics eliminate unnecessary copies -- Configurable limits for large binary data - -### 3. Performance -- Template instantiation creates optimal specialized code (zero-overhead abstraction) -- Compile-time `if constexpr` eliminates runtime branching -- Direct memory access via `reinterpret_cast` (validated by nvImageCodec API contract) - -### 4. Extensibility -- Easy to add new types to the variant -- Template helpers work with any numeric type -- Visitor pattern scales naturally - -### 5. Debugging -- Clear `std::visit` logic shows exactly what's stored -- Type-safe string conversion for logging -- `#ifdef DEBUG` blocks provide detailed extraction traces - -### 6. Binary Safety -- Configurable size limits (`max_binary_tag_size_`) prevent memory bloat -- Large binary tags can be truncated without affecting other data -- Clear indication when truncation occurs (debug output) - ---- - -## Evolution History - -The implementation evolved through multiple iterations: - -### Version 1: Basic Types -```cpp -std::unordered_map> -``` -- Initial proof of concept -- Supported only basic scalar types - -### Version 2: Array Support -```cpp -std::unordered_map>> -``` -- Added vector type for multi-value tags -- Enabled BitsPerSample, SubIFD arrays - -### Version 3: Complete TIFF Coverage (Current) -```cpp -using TiffTagValue = std::variant< - std::monostate, std::string, - int8_t, uint8_t, int16_t, uint16_t, int32_t, uint32_t, int64_t, uint64_t, - float, double, - std::vector, std::vector, std::vector, - std::vector, std::vector, std::vector ->; -``` -- **17 types** covering all TIFF specifications -- BigTIFF support (64-bit types) -- Floating-point support (FLOAT, DOUBLE) -- Complete array type coverage - ---- - -## Integration with nvImageCodec API - -### Metadata Extraction Flow - -``` -┌─────────────────────────────────────────────────────────────┐ -│ 1.
