- Fixes a writing issue for float values less than 1
- Fixes a missing definition of `EXIF_DATETIMEDIGITIZED` tag
- Adds support for some common camera shot metadata
- Adds missing metadata to writing tests
The following plugins automatically gain support for the new metadata: AVIF, IFF, HEIF, JXL, JXR, PSD and TGA (V2E).
The new metadata added with this patch is usually saved by smartphones (e.g. iPhone or Google Pixel).
Highlights:
- Adds support for a new palette changer chunk. Some test cases attached to #38 .
- Fixes the reading of ILBMs with the mask (test case: [cyclone.iff](/uploads/d8734d2155fd0d21f7b003b37e0d1259/cyclone.iff)).
- Adds support for HAM5 encoding.
- Adds more test cases created using [HAM Converter](http://mrsebe.bplaced.net/blog/wordpress/).
- Adds support for Atari STE RAST chunk outside FORM one (test case: [fish.iff](/uploads/c461cf4b6a1423cec60fbce645d9fd07/fish.iff)).
NOTE: I contacted Sebastiano Vigna, the author of the PCHG chunk specifications, and he provided me with:
- Some images to test the code (but I can't include them in the test cases).
- Permission to use [his code](https://vigna.di.unimi.it/amiga/PCHGLib.zip) without restrictions: Huffman decompression was achieved by converting `FastDecomp.a` via AI.
Closes#38
For example, the PCX plugin converts all RGB images to RGB(A)32. So if you try to save a 1 GiB RGB888 image, it will be converted to RGB32 image so, you need additional 1.25GiB of ram. The conversion now occurs line by line, significantly saving memory.
Adds TGA 2.0 compliance:
- Support for Extension Area, Developer Area and Footer (metadata support)
- Support for 15-bit and 16-bit per pixel images (both RGB and Indexed)
- Full support for rotation on reading (we cannot use Qt transformations because only a subset is part of the TGA specification)
- When writing you can choose the supported version (subType)
- Improved writing speed (approximately 10 times) and removed whole image conversions (significant memory savings)
It pass the [TrueVision TGA 2.0 conformance suite](https://github.com/zigimg/test-suite/tree/master/fixtures/tga).
Test changes:
- Read test: added ability to skip a specific test on sequential devices (via JSON behavior file)
- Write test: added the ability to set the subType when writing (via JSON properties file)
Closes#37
- Removed temporary buffer of uncompressed image size when reading (loads images using half the memory)
- Added native support for Grayscale images (they are no longer converted to RGB(A) 32 when reading/writing)
- Fixes wrong X channel value on RGBX32 images (CCBUG: 499584)
It should also reduce loading times for corrupted images.
Closes#33
Add the following features:
- RGB8 image data support (test case added)
- RGBN image data support ([Clouds.iff](/uploads/9db869350f74421bf1813fa7d4332f4f/Clouds.iff))
- CAT chunk support: you can have more than one image for file (test case added)
- Image transformation support via EXIF data
[RGBN/RGB8](https://wiki.amigaos.net/wiki/RGBN_and_RGB8_IFF_Image_Data) files are used in Impulse's Turbo Silver and Imagine.
Closes#34
Read-only support for most common Interchange Format Files (IFF). Supports IFF saved by Photoshop for the Amiga and Maya platform and HAM6 coded files.
Closes#29
