Nico Weber	54dcb17062	Tests/LibGfx: Add two more test jbig2 files ... I extracted a pure-white jbig2 that has only a PageInformation segment from a PDF and manually edited the bytes to reduce the bitmap size to 47x23 and to clear all unneded bits (except, in the black version, the page color bit is set).	2024-03-10 10:10:55 -04:00
Nico Weber	bd60d1db7e	Tests/LibGfx: Add a simple test jbig2 file ... I created this by running jbig2 -i Tests/LibGfx/test-inputs/bmp/bitmap -f bmp -o bitmap -F jb2 using the `jbig2` tool whose source code is in the zip file here: https://www.itu.int/rec/T-REC-T.88-201808-I (Just `make jbig2` in Software/JBIG2_SampleSoftware-A20180829/source was enough to build it.) As far as I can tell (cf `JBIG2_EncMain()` which always writes `1` to the flags byte in the file header), this tool always writes files in the sequential organization.	2024-03-09 16:01:22 +01:00
