Perhaps the colorspace can be added in the future to the list of string formats that one can return. I use this often also in my scripts and have to extract it from the -verbose info using sed commands. Not high priority as it can be done, but seems like a good thing to be able to get to easily. Fut...

I don't claim to be an expert, but some things you might consider. First convert to something like RGB PNG or TIFF (uncompressed) to preserve color, then resize, then convert to JPG. JPG is a lossy compression and will change colors some, so make that the last step so that you don't compress twice (...

You should be able to specify x and y changes all in one fx equation.

Reference Examples to -fx:

Post your equations so that we can see what you are trying to do and perhaps make suggestions on implementation.

Note that your histogram shows four colors! There are five odd colored pixels that appear to be more in the green area: Histogram: 82796: (255,255, 0) #FFFF00 yellow 75818: ( 40,215, 97) #28D761 rgb(40,215,97) <- green 3669: (218,218,218) #DADADA rgb(218,218,218) <- gray roads 5: ( 19,224,124) #13E0...

I have now solved this problem. I needed to install the Mac framework for Ghostscript, even though the GS docs say that should not be necessary. MacOS X The unix source distribution (.tar.gz) builds fine on Darwin/MacOS X, albeit without a display device. You can generally just use the Makefile gene...

Thanks. I understand with regard to your naming conventions. I will test this out at my earliest possibility. I look forward to using it. Thanks for the heads-up about the -channel setting. This should work just fine.

Another simpler method to merge images is the -append and +append commands

See:

I do not know how it compares in speed and memory requirements to montage with mode concatenate, but the command is much simpler.

Are you shrinking or enlarging your image? The default filter for shrinking is Lanczos and is probably the best one to use. The default filter for enlarging is Mitchell according to the page below. See: http://www.imagemagick.org/Usage/resize/#filter for a list and comparison of all the IM filters.

Wow! That was fast? You are terrific! What happens if the image is RGB not grayscale? Do you get multiple values that need to be separated? Not to look a "gift-horse" in the mouth, but would it make sense to shorten the %[standard-deviation] to %[std] (for less typing) or do you think that...

I know you all are busy, so this is not a high priority, but a when you can request (or add to enhancement list) as there are workarounds, but I use them frequently when doing scripting. Would it be possible to add a few more string formats to the list you have to be able to retrieve the min, max, m...

I am no expert and have no way to test these, but to only overlay the first frame only, try something like the following, convert \( multi.tif[0] stamp.gif -gravity NorthEast -geometry +150+150 -compose multiply -composite \) multi.tif -delete 1 -compress group4 tmp.gif or convert \( animation_text....

I understand. It was someone else who brought it up and I could not make it work so I thought I would bring it to your attention for verification.

The pict file found at

does not seem to convert correctly or display in IM.

How can I convert an 8-bit grayscale image to a 16-bits tiff WITHOUT modifying any pixel values. I have tried: convert <infile> -depth 16 <outfile> but this still gives 8-bits according to identify -verbose info: similarly for convert <infile> -level 0%,100% -depth 16 <outfile> but this still gives ...
