JBIG2DECODE in pdf

Hi,
I wish to decode a jbig2 image in a pdf.
I see that ImageMagick understands CompressionMethod JBIG2, but not the format.

is there an alternate format I should use for this scenario?

Kind Regards
Martin

Re: MagickImage.Write 0 size empty result

Hi,
Not yet, but I currently think the problem lies else where.
Happy to have it left with me, unless I come back.
I'll confirm if I resolve the problem - not currently full time on this, so unsure of timescales.

The original data is MagickFormat.G4, CompressionMethod.Fax...

MagickImage.Write 0 size empty result

Hi, I've got some code that uses MagickImage class. The code used to work (I thought) so obviously something's changed, and I'm trying to troubleshoot the problem... My code looks like this: MemoryStream ms = null; MagickImage image = new MagickImage(data, readSettings); image.Format = MagickFormat....
