don't think splice works with mogrify. you can try. I am not sure. mogrify is old and does not support all functions that convert does.

try

convert image -channel rgba -alpha on -bordercolor black -border 1 result

convert image -bordercolor black -border 1 result

will add a 1 pixel border outside the bounds of the image

see http://www.imagemagick.org/Usage/crop/ and esp http://www.imagemagick.org/Usage/crop/#border

see http://www.imagemagick.org/Usage/files/#read_mods convert image.yuv[0-9] ... image.bmp converts the first 10 frames, but if bmp does not support multiple frames, then you will get image-0.bmp, image-1.bmp, etc. So you may want to convert to some image type such as .gif or .png to have a 10-frame...

montage is what you want. it will do the job if you give it the right params

see http://www.imagemagick.org/Usage/montage/ esp http://www.imagemagick.org/Usage/montage/#tile

try

montage image1 image2 ... image10 -tile 5x2 -geometry +1+1 resultimage

I am not an expert on such matters, but if you install IM via MacPorts, then you need to install libfpx via MacPorts so that they are all in the same special directory (/opt as I recall) used by MacPorts, so that IM knows where to find it by default. Then you need to reinstall IM after you install l...

My ncc compare seems to be working and useful, so I have now created and uploaded a script, similar, to my web site below.

see Anthony's new additions to -crop as of IM 6.5.8-9 at http://www.imagemagick.org/Usage/crop/#crop_equal

It would be quite simple to add a -normalize option to the compare program to subtract the mean and divide by the standard deviation before the compare. Would that be a useful addition to the compare program? In my opinion a proper NCC equal size image compare would be useful. See my script above. ...

This is a cut at a grayscale Normalized Cross Correlation Compare of two images of the same size. (From mathematics at http://en.wikipedia.org/wiki/Cross-correlation#Normalized_cross-correlation) Bad values are near 0 and good values near 1. A perfect match should be 1. Change infile1 and infile2 to...

It is likely image dependent. But I like to use -metric rmse (and look at the fractional value in the parenthesis, not the first raw value). Perhaps you need to normalize by the image mean (rmse/mean). Don't really know for sure. see http://www.imagemagick.org/Usage/compare/#statistics What you real...

I tried blend & dissolve but image intensity decreases if I want to mix two images equally. My idea is to draw series of red coloured circled then draw yellow on same image so that at points of intersection I get orange . Is that possible ? Try -compose plus -composite, see http://www.imagemagi...

The special setting option however is option:compose:args NOTE the 's' in the name!!!!! As such you are NOT passing the argument to the 'compose' method correctly. OOPS :oops: I never noticed that. How embarrassing! I spent quite some time testing and never thought about the plural on args. I think...

What I really want is to convert the image from one colorspace representation of the data to the other, whether the header knows about it or not. But there are ways to do that, so this is really not an issue. First, if I just want to use it in a script as a temp file, then miff will do the trick. Se...
