Since -draw takes a filename as a parameter, I don't know how to combine these. Maybe someone else knows how to do this. Have you considered using -composite and -geometry instead of -draw? If you chose draw for a reason, hopefully someone can answer that question. If -composite and -geometry haven'...

( and ) have to be escaped to \( and \) on Linux, % must be escaped to %% in Windows batch files. Line continuation is \ on Linux, ^ on Windows.

My guess would be to try some larger median and then follow that by some moderate shapening or unsharp masking or possible blurring. Sadly a sharpening step anywhere only amplified the problem in some areas. It was a good suggestion so I'll try it on the other photos. Low light photography is also ...

You could try -despeckle or some other denoising filter. Is there a list of denoising filters? You could try a larger median value and then some sharpening afterwards. A good idea I hadn't thought of. your noise looks like film grain And paper texture. My consolation is that I already have the imag...

Again, apology for the irritating error/advert page. The host has been changed and only a sample piece of the image is given. I don't know in what way it could help address the noise, but the original scan was in RGB. http://i54.tinypic.com/hwi905.png With some final tweaking, this project is soon t...

I have a scan of a 60-year-old photo. At 29 megapixel, it is as much noise as image. Any advice on what filter might clean this up? http://i53.tinypic.com/x2qm42.png after "-median 1 -gaussian-blur 2x0.5" http://i55.tinypic.com/2iqeki0.png Before this I: touched up the photo by hand to rep...

There are endless ways to do this. External - keep a list of filenames or file hashes or image fingerprints File level - alter the filename, directory, or use file system metadata (would depend on your file system) Image - set a single pixel or some more complex watermark - maybe your processing alr...

I just tested the latest version and the bug is still there. At least the two of us have a workaround now. What does png32: do anyway PNG32: forces the 32-bit PNG format, that is 8 bits for each red, green, blue, and alpha transparency channels. Alternatively, you can use -define png:color-type=6 to...

I verified that I really have "6.6.6-3 2010-12-01 Q16" an re-ran some tests. Doesn't work (transparent turn to balck): composite USAsnow4.png transp_rain4.png a.png composite USAsnow4.png transp_rain4.png -type TrueColorMatte b.png Works: composite USAsnow4.png transp_rain4.png -define png...

I reported this as a bug:
viewtopic.php?f=3&t=17635

weatherbadger, I linked to your two images at weatherbadger.com. I'm sure the developers would appreciate you leaving them up, or providing new links in the above bug report.

My ImageMagick came from a zip file labeled 6.6.6-2 but reports as 6.6.6-3 2010-12-01 Q16. I am using the Windows portable version. weatherbadger reports my PNG32: workaround not working in 6.6.1-0 2010-07-29 A seeming related problem: http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&am...

ImageMagick is in a folder labeled 6.6.6-2 but reports as 6.6.6-3 2010-12-01 Q16.

Maybe this one too, but harder to tell:
viewtopic.php?f=1&t=17597

I am using version 6.6.6-2 or 6.6.6-3. (seems to be some labeling confusion in this version)

Original post: Composite with different transparencies However a recent change was that IM is attempting to generate smaller PNG pallette image (with multiple levels of alpha). However in this case it is failing to preserve alpha!!!!! This is a known BUG but you should report this (as a new topic) t...

Anthony's solution works great!!! I will write up the bug. My suspicions are that the chart plotting software which gives a transparent background to the snow image has moved the transparency setting goalposts somehow... GreenKoopa - you said one uses transp white, and one transp black, and one inde...
