| * | GIF: Fix inconsistent function return value handling. | Michael Drake | 2021-11-02 | 1 | -53/+52 | |
| | | | | | | This uses the proper enum type, a consistent name for return values, and corects cleanup on error. | |||||

| * | GIF: Don't call bitmap_modified after for clear frame disposal method. | Michael Drake | 2021-10-22 | 1 | -13/+15 | |
| | | | | | | | | | | | | | Due to recursion through gif_internal_decode_frame, the inner call through the function for the clear would call modified, but the outer call would already have done its get_buffer, and then do the the decode and call modified again. This would break cases where clients do any buffer data transformation, since the decode would be done on top of a client buffer representation rather than a libnsfb buffer representation. | |||||

| | | ||||||
| * | lzw: Direct output into frame data, avoiding stack. | Michael Drake | 2021-04-18 | 1 | -2/+81 | |
| | | | | | | If the frame is non-interlaced, and has the same rowstride as the full image, then we can decode lzw directly into the output image. | |||||
| * | gif: Handle any uncompressed output before exiting due to error. | Michael Drake | 2021-04-18 | 1 | -2/+2 | |

| | | | | | Gives the client a chance to detect memory bombs. | |||||
| * | libnsgif: Fix LZW Minimum Code Size check. | Michael Drake | 2021-03-29 | 1 | -1/+1 | |
| | | | | | | The passed value is now checked for validity in lzw_decode_init() too, but checking here allows an early exit. | |||||

| * | Fix allocation size comparison in previous frame recorder. | Michael Drake | 2020-07-06 | 1 | -1/+1 | |

| * | Disposal Method: Handle Restore to previous with saved image. | Michael Drake | 2020-07-06 | 1 | -21/+80 | |
| | | | | | | | | | | | | Previously we decoded a previous frame over the current frame data to handle resoration. However, the previous frame depended on its own previous frame state for correct decode. Now we just make a copy of the previous frame data and copy it back to handle the GIF_FRAME_RESTORE case.
