* API: Use uint32_t for background colour info member.Michael Drake2022-03-242-22/+4
| | | | | This avoids increasing alignment of pointer type where we handle the background fill.
* Util: Improve host endian detection for older GCCs.Michael Drake2022-03-241-2/+2
| | | | Co-authored-by: John-Mark Bell <jmb@netsurf-browser.org>
* Tests: Update decoder to set required pixel format.Michael Drake2022-03-231-1/+1
|
* Docs: Mention colour formats in README.Michael Drake2022-03-231-4/+7
|
* GIF: Build colour tables using colours with client channel ordering.Michael Drake2022-03-231-18/+28
|
* API: GIF: Take client colour layout on nsgif_create().Michael Drake2022-03-232-3/+99
| | | | Map the requested layout to appropriate pixel channel offsets.
* API: Add enum for colour component order selection.Michael Drake2022-03-231-3/+58
| | | | | This will allow the client to choose the colour component order for decoded bitmaps.
* GIF: Support AnimExts Looping Application Extension.Michael Drake2022-03-081-6/+45
| | | | The the NETSCAPE2.0 and ANIMEXTS1.0 extensions are identical.
* GIF: Fix handling of loop count value in application extension.Michael Drake2022-03-081-0/+3

* Docs: Update README to mention nsgif_data_scan errors.Michael Drake2022-03-071-4/+9
|
* Test: Make decoder more tolerant of bad gifs.Michael Drake2022-03-031-12/+11
| | | | | This makes us keep going if the scan or a frame decode fails, ensuring everything is tested.
* API: Document nsgif_data_scan return code errors being non-fatal.Michael Drake2022-03-031-0/+3
|
* API: Single error code for end of data.Michael Drake2022-03-032-8/+2

* GIF: Fix frame background colour disposal for frame clipping.Michael Drake2022-03-031-4/+6
|
* GIF: Fix frame limit off-by-one.Michael Drake2022-03-031-2/+2
|
* GIF: Apply minimum frame delay only in nsgif_frame_prepare().Michael Drake2022-03-021-7/+6
| | | | | Now the frame info contains the raw delay from the GIF file, without the minimum applied.
* Test: Add transparency to frame info dump.Michael Drake2022-03-021-0/+1
|
* Test: Default to single loop if loop count is zero.Michael Drake2022-03-021-0/+4

|
* Test: Use tabs for indent in test runner script.Michael Drake2022-02-261-31/+31
| | | | | Previously it was 4 spaces for first level indent, 1 tab for second level, 1 tab plus 4 spaces for third level.
