ooBJ3u	b23d82c45e	Use mono.jb2 for tests ... This also uncovered a bug in jbig2enc where it uses the wrong unit for resolution.	2023-11-29 00:00:00 +00:00
ooBJ3u	085dd192f6	Add support for JBIG2 (generic coding) ... Implements the proposal detailed at josch/img2pdf#112 (comment) This is a limited implementation of JBIG2, which can be extended to support multiple pages, symbol tables, and other features of the format in the future. To test, I included a test fixture. You can also download 042.bmp (the same one as @josch already downloaded in josch/img2pdf#112 (comment) from https://git.ghostscript.com/?p=tests.git;a=blob_plain;f=jbig2/042.bmp;hb=HEAD and run the following command: jbig2 042.bmp | img2pdf > 042.pdf This results in a small PDF, just as @josch originally found in the comment mentioned above. This is my first contribution to this repository so let me know if something else is needed. Thanks for a great library!	2023-11-29 00:00:00 +00:00

Johannes Schauer Marin Rodrigues	29921eeabd	the default PDF/A icc profile is /usr/share/color/icc/sRGB.icc, /usr/share/color/icc/OpenICC/sRGB.icc or /usr/share/color/icc/colord/sRGB.icc depending on which one exists	2023-06-11 21:56:21 +02:00

Johannes Schauer Marin Rodrigues	cb2644c34f	do not include thumbnails in the output by default unless --include-thumbnails is used ... This is relevant for the MPO format which otherwise would result in PDF files containing the same image in different sizes multiple times. With this change, the default is to only have a single page containing the full MPO. This means that extracting that MPO also gets the thumbnails back. With the --include-thumbnails option, each frame gets stored on its own page as it is done for multi-frame GIF, for example. Closes: #135	2023-06-11 07:31:07 +02:00
Patrick McCarty	81502f21af	Convert creation/modification dates to UTC (fixes #155) ... Ensure that timezones are correctly interpreted in the input by calling `.astimezone()` as appropriate on datetime objects, and store the resulting date fields as UTC. One could argue that datetimes in the local timezone be stored in the PDF, but then the date string handling becomes more complicated; the PDF and XMP date specs both use the `Z` suffix to indicate UTC time, but other +/- offsets require different syntax between the two specs.	2023-06-10 17:53:03 -07:00
