Mirco Miranda	64d51ed610	pcx: multiple fixes (2) ... - 1-bit writer: checks where is black and use NOT operator only if needed - Fix images with witdh == 65536(*) - Checks result of disk writes and reads on all formats (*) PCX formats support images with with of 65536 but only if the header field bytesPerLine is valid (no overflow). This means that the width 65536 is supported on 1bpp images only. The previous version of the plugins wrote an image with width of 65536px in the wrong way and it was unable to read it (wrong image returned). I verified that Photoshop and Gimp weren't able to read the image either. (cherry picked from commit d57ff91f8b)	2023-05-25 23:58:42 +02:00
Mirco Miranda	bb66367bc8	PCX: Fix reading of the extended palette ... The VGA palette starts 769 bytes before the end of the file. There may be PADs between the end of the image and the start of the palette. BUG: 463951 (cherry picked from commit 14742cb502)	2023-05-25 23:58:42 +02:00

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
