Interesting. I thought PDF normally convert the format into .jbig2 for embedding into the PDF itself.
- cwt137 5y agoPDF doesn't encode something. PDF supports a few data formats. They call them "filters"; for example CCITT Fax, JBIG2, DCT, RLE, etc. Its up to the PDF creation program to pick the best data format for the image it would like to put into the PDF.
