A: Sorry for the delay. I just got back from vacation. When converting PDF to SVG we convert any PDF image format to JPEG or PNG.
The conversion is done in a lossless way:
- non-lossy image formats are normalized to PNG - CCITTFax, JBIG2, Flate, RLE, LZW)
- lossy formats are saved as JPEG. In most cases we do not recompress data (i.e. DCTDecode stream is directly saved as JPEG). As a result Quality factor is not relevant (i.t. will be whatever PDF includes). If you would like to down sample images in SVG you could do so either before conversion (e.g. using 'pdftron.PDF.Optimizer',
