As the outline.gif has 3 frames and the text.gif has 27 frames, they are multiples of each other. So just merge the outline 9 times to match the number of frames convert \( text.gif -coalesce \) null: \( outline.gif outline.gif outline.gif outline.gif outline.gif outline.gif outline.gif outline.gif ...

With regard to your original question about uneven illumination correction, you could try my gaussian redist script to adjust each frame to the same gaussian histogram distribution. You can find the Unix bash script redist at

convert logo: -unique-colors -depth 8 text:

or

convert logo: -format %c -depth 8 histogram:info:

Post your source images as well as the mask.

Generally the background and overlay (first and second) images are not transparent. You may want to review

You have a binary (1-bit) tif image. Perhaps you need to convert it to grayscale first, before doing any processing.

convert num.0015.tif -depth 8 num.0015_d8.tif

or

convert num.0015.tif -type Grayscale num.0015_tg.tif


Both will make an 8-bit image.

I am no expert at animation, but your two animation do not have the same number of frames and I suspect this will be key to overlaying them one-to-one. identify text.gif text.gif[0] GIF 250x234 250x234+0+0 PseudoClass 256c 8-bit 176.459kb text.gif[1] GIF 250x234 250x234+0+0 PseudoClass 256c 8-bit 17...

You can do the following to unfold the edges (mirrored) by say 12 pixels pad=12 convert inputimage \( +clone -bordercolor white -border ${pad}x${pad} \) +swap -virtual-pixel mirror -fx "v.p{i-$pad,j-$pad}" outputimage The bordercolor is immaterial, it just increases the size of the resulti...

If you are on Unix or Mac and want to resize to a square format, you can try my squareup bash script at

Thanks.

I recently had to build IM from source. But found that many image types including convert to png, jpeg and tif did not work. I got some help from Sean Burke to find those delegate libraries. Now when I run Anthony Thyssen's flicker_cmp, I get error messages about sh: line 1: gs: command not found sh...

I have been an IM user for less than a year now and have until now been using the binary builds on my Mac OS 10.4 Tiger system. When Apple released OS 10.5 Leopard, IM started building binaries for it and th IM binary for Tiger no longer seems to include X11 display support. It would be nice if this...

Here is a set of commands. But you would likely need to script them. convert hex10.png -fuzz 10% -trim +repage hex10_trim.png // trim width=`identify -format %w hex10_trim.png` // get width of trimmed image height=`identify -format %h hex10_trim.png` // get height of trimmed image [ $width -gt $heig...

Do each image separately,

convert image1 -colorspace Gray outimage1
confert image2 -colorspace Gray outimage2

jpeg is a lossy (compressed) image format and will not preserve colors exactly. You might try first creating it as a png and then converting to jpeg while setting the quality to 100%, but even that may not help. Also jpg does not allow transparency. So png is your best format.

try

convert <first_image> <second_image> -colorspace Gray <output_file>
