Re: irregular channel geometry error/missing image channel

Yes, that's exactly what it does for me (with Jiv and Display). It's interesting to note that, because I'm using several different viewers (Kakado, IrfanView, display (IM), jiv (Jasper) and FastStone Image Viewer) I get completely different results (meaning they implement the standard in different w...

Re: irregular channel geometry error/missing image channel

Yes, it lists:

DELEGATES bzlib djvu fontconfig freetype gs jpeg jng jp2 lcms openexr png rsvg tiff x11 xml wmf zlib

I was able to use jasper to convert these j2k's to jp2's. They can be seen at:

Re: irregular channel geometry error/missing image channel

"Note I am not an expert on JP2000 as I rarely use it." I just noticed this at the bottom of your post and had to laugh. I've been working with JPEG 2000 for about 6 weeks now and it seems there are no experts. Pasting two images together to create a new image would take about 10 minutes in any norm...

Re: irregular channel geometry error/missing image channel

Yes, IM doesn't list j2k as a suported format. Hower J2K (and JPC and J2C for that matter) are just JP2 w/o a header. Really kinda suprises me it doesn't handle J2K in the same way it would handle J2C (which it does list as supported). I changed the extention to j2c and got the same result. I added ...

Re: irregular channel geometry error/missing image channel

I've attached the files that give the "irregular channel geometry not supported" message. They are 1920x540 HD images encoded by a pair of ADV212 jpeg encoders (Y and CrCb) that were merged for color. Jiv and kakadu have no problem displaying these images. The REAL problem I'm trying to solve is joi...

Re: irregular channel geometry error/missing image channel

I don't have a common place I can point you to. Is there some other way? Can I email them to you?

irregular channel geometry error/missing image channel

Just doing: "convert test_image1.jp2 test_image1.png" I'm trying to convert a 1920x540 j2k or jp2 formatted file to ANYTHING else and I keep getting these errors. The j2k version of the file gives the "irregular channel geometry" error and the jp2 file (same file with a header) gives the "missing im...

Re: "irregular channel geometry" error joining files

Thanks to both of your replies. I do have the IM libs installed but there's no j2k support. It's odd because there is j2c support which is the other JPEG2000 streaming format. I'm not sure what the difference is. The other thing I take from this is that jp2 is supported. I can convert my j2k images ...

"irregular channel geometry" error joining files

I've got two 1920x540 (1080p) j2k (JPEG 2000) images that are the upper and lower halves of a full 1080p frame. I need to stitch or join these two images into a single 1080p frame within a C program (reading raw data from a camera and doing some preprocessing). I have two issues (at least...) 1) I h...
