James Jackson-South	dfdc0734e3	Validate CgBI chunk order in PNG decoder Handle CgBI chunks consistently when they appear after IHDR by routing both identify/decode paths through a new `ReadCgbiChunk()` method that immediately validates already-read headers. This prevents invalid CgBI images from bypassing compatibility checks when chunk order is unusual. Added PNG tests that reorder the first two chunks to confirm incompatible CgBI headers now throw in both identify and decode flows. Also renames `ZlibInflateStream` to `ZlibInflateReader` and updates EXR/PNG/TIFF call sites for clearer intent.	2 months ago

Andreas Eriksson	7b13e1df1b	Add generated animated PNG tests for Identify and Decode frame counts	6 months ago
Andreas Eriksson	ac1905328d	Fix Identify returning incorrect frame count for animated PNGs The Identify method had two bugs when processing fdAT (FrameData) chunks: 1. A spurious Skip(4) before SkipChunkDataAndCrc caused the stream to be misaligned by 4 bytes, since chunk.Length already includes the 4-byte sequence number. 2. Unlike Decode, which consumes all fdAT chunks for a frame in one shot via ReadScanlines + ReadNextFrameDataChunk, Identify processed them individually, calling InitializeFrameMetadata for each chunk and inflating the frame count. The fix removes the extra Skip(4) and adds SkipRemainingFrameDataChunks to consume all continuation fdAT chunks for a frame, mirroring how ReadNextFrameDataChunk works during decoding.	6 months ago
