They all seem fine in Firefox 3.5.8. In Internet Explorer 8.0.7600, some of them don't animate. If you have created them in Photoshop, what part does IM play? Perhaps you created the full-size versions in PS, and Joomla used IM to shrink them so 15 can fit on one page. If you can discover what Jooml...

(IM version 6.6.0-8 Q16 on Windows 7.) The documentation talks about a "prune" kernel, but it doesn't work: convert in.png -channel alpha -morphology erode:3 prune -background blue -flatten out.jpg convert: UnrecognizedKernelType `prune' @ error/convert.c/ConvertImageCommand/1968. Can I pr...

As Bonzo says, you can just keep going. convert a.png -options -options2 ... -options26 z.png Two main things to remember: 1. Options like -background, -gravity and so on take default values in the multiple commands, but will "carry through" in the single command version. 2. If you use an ...

You can put images on the web somewhere, and paste the URLs here. I have a distribution of 6.5.8-10 for Windows 64-bit static, executables but not source, if that will help. I can put it on the web. Sorry, I can't help with the code. But if you can provide a minimal program and image files that show...

Very strange, as I wouldn't expect pict.jpg to be modified in any way. Can you post the image?

convert infile NULL:

returns 0 on success, 1 on failure.

IM and GIMP find no transparency in DRVq3ITTKjDe3Ug9.tif

I suggest you download that uploaded file, and try it again in Photoshop.

I'm not an IM developer, but: 1. IM handles Unicode filenames (Arabic, etc), if that is what you mean. 2. You just need to add an entry to delegates.xml, as far as I can see. 3. You might find the architecture document useful: http://www.imagemagick.org/script/architecture.php . IM stores images as ...

According to my flakey maths, in a series of random bytes I would expect to see those eleven bytes occuring by chance once every 256^10 bytes, which is 10^24 bytes, which is one tera-terabyte. So I suggest you either (a) do the messy parsing or (b) calculate how many files you expect, then look for ...

GMIC won't run on my Windows 7 64-bit platform. From the screenshots, I notice that GMIC has adjustable parameters. I wonder if one can find a set of parameters that will suit every image? I doubt it. For fmw's Cloe shot: I suggest the edge is applied to the original (possibly median'ed first), rath...

The following seems reasonable to me: 3x3 is for 3-channels (eg RGB or CMY) without translation 4x4 is for 4-channels (eg RGBA or CMYK or CMYA) without translation 5x5 is for 5-channels (eg CMYKA) without translation 4x3 is for 3-channels (eg RGB or CMY) with translation 5x4 is for 4-channels (eg RG...

I think your question boils down to: "My program receives a stream of concatenated JPEG files. How do I know where one ends and the next begins?" The proper answer, I think, is that you should parse each one as it arrives. The informal answer is that each file may finish with any byte sequ...

When the dust settles on this issue, perhaps someone could ensure the documentation states what matrix sizes are available (3x3, 4x4, 5x4, 5x5, whatever), and what each of them means, eg dstR = a[0] * srcR + a[1] * srcG + a[2] * srcB + a[3] * srcA + a[20] dstG = a[5] * srcR + a[6] * srcG + a[7] * sr...

Is anyone is planning a "face detection" system for ImageMagick? As many cameras now offer this facility, I suppose the software requirements are fairly simple and well-known (but I don't know the rate of false positives and false negatives). It would be a neat feature when we want to proc...
