Mirco Miranda	9c6c0c01ae	TGA: Support for TGA specification 2.0 ... 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	2025-08-23 09:20:09 +00:00

Mirco Miranda	0378bd67e1	TGA: Fixed GrayA image loading error ... Gray TGA images with alpha were loading incorrectly and tests did not detect the error since the BW(A).TGA images were actually RGB(A) images.	2024-10-24 15:07:44 +00:00
Alex Merry	f0f6d14367	Add simple autotests ... Two main tests: read the file and compare to a given image (loaded from png), and write a file out and compare to a previously-written image. The write test in particular is kind of fragile, but it should help catch some errors where a code change was not intended to affect the output of the plugin. Tests are included for all the writable formats, as well as every readable format that GIMP can write to (and so I could easily get an example of). REVIEW: 115430	2014-02-03 15:03:29 +00:00
