I am using Imagemagick to turn a gif into a corresponding series of jpgs and I am trying to determine when each jpg happens in a series.
stolen from How do I detect an animated GIF's ticks per second?: identify -format "%T ticks: %f: Frame[%s] %m %wx%h %P%O %r %z-bit\n" tree.gif
4 ticks: tree.gif: Frame[0] GIF 247x175 247x175+0+0 PseudoClassRGBMatte 8-bit
4 ticks: tree.gif: Frame[1] GIF 247x175 247x175+0+0 PseudoClassRGBMatte 8-bit
4 ticks: tree.gif: Frame[2] GIF 247x175 247x175+0+0 PseudoClassRGBMatte 8-bit
4 ticks: tree.gif: Frame[3] GIF 247x175 247x175+0+0 PseudoClassRGBMatte 8-bit
4 ticks: tree.gif: Frame[4] GIF 247x175 247x175+0+0 PseudoClassRGBMatte 8-bit
4 ticks: tree.gif: Frame[5] GIF 247x175 247x175+0+0 PseudoClassRGBMatte 8-bit
and identify tree.gif gives me

can anyone translate this output that will tell me either the framerate or when each frame appears? Extra points if you can make it work using RMagick.
There are complications. First of all, you need to use the %T and %s escapes to look at the frame number and the delay (in centiseconds), not the vanilla identify command. Second, the delay from one frame to the next varies, so you need to be prepared to deal with cases when your animated GIF does not have a unified "frame rate" from end to end.
Here is an example command: identify -format "Frame %s: %Tcs\n" A.gif

Looking at some ICO files that have PNG data instead of ICO and I am trying to create the same. Example:
$ identify sample.ico
sample.ico[0] PNG 32x32 32x32+0+0 8-bit sRGB 884B 0.000u 0:00.000
sample.ico[1] PNG 16x16 16x16+0+0 8-bit sRGB 884B 0.000u 0:00.000
$ file sample.ico
sample.ico: MS Windows icon resource - 2 icons,
32x32, 16 colors withPNG image data, 32 x 32, 8-bit/color RGBA, non-interlaced, 4 bits/pixel,
16x16, 16 colors withPNG image data, 16 x 16, 8-bit/color RGBA, non-interlaced, 4 bits/pixel
Playing around I have found I can do something like this to get PNG ICO:
$ convert icon-32x32.png png8:test1.ico
$ identify test1.ico
test1.ico PNG 32x32 32x32+0+0 8-bit sRGB 934B 0.000u 0:00.000
But if I use multiple input files I get multiple output files:
$ convert icon-16x16.png icon-32x32.png png8:test2.ico
$ ls -1 test2*
test2-0.ico
test2-1.ico
Not prefixing with png8: converts the data to ICO.
$ convert icon-16x16.png icon-32x32.png test3.ico
$ identify test3.ico
test3.ico[0] ICO 16x16 16x16+0+0 32-bit sRGB 5.43KB 0.000u 0:00.000
test3.ico[1] ICO 32x32 32x32+0+0 32-bit sRGB 5.43KB 0.000u 0:00.000
If the file is too big for the ICO format, the PNG is "preserved":
$ convert ../icon-32x32.png ../icon-512x512.png test4.ico
$ identify test4.ico
test3.ico[0] ICO 32x32 32x32+0+0 32-bit sRGB 53.4KB 0.000u 0:00.000
test3.ico[1] PNG 512x512 512x512+0+0 8-bit sRGB 53.4KB 0.000u 0:00.000
How can I create a ICO file with PNG data for all sizes in ImageMagick?
Have not found any solution with imagemagick but one can use GIMP.
Just create a layer for each size and export as file.ico.
In options dialogue that appear check off Compress (PNG).
One can also set bpp etc. For lower resolutions one can use for example:
16x16 4bpp, 1-bit alpha, 16-slots palette
24x24 4bpp, 1-bit alpha, 16-slots palette
32x32 8bpp, 1-bit alpha, 256-slots palette
48x48 ...

I am trying to combine three channel-based TIFF files into a single RGB one. The individual files look like this (this one is red):
Based on another answer here, I tried this command to merge them:
convert \
\( ./raw/red.TIF -channel r -separate +channel \) \
\( ./raw/green.TIF -channel g -separate +channel \) \
\( ./raw/blue.TIF -channel b -separate +channel \) \
-set colorspace sRGB -combine \
./test.tif
However, instead of a nice full-colour image, what I get instead is:
(you can just make out the tiny, incorrectly combined image in the top left corner).
What is it I'm doing wrong here?
EDIT: You can get these TIFF files here. (These are Landsat images.)
Your TIFFs are pyramidal, or multi-resolution. You can see that with this command to look at the individual images in the blue TIFF:

To make the full-size RGB render you need to take the zero-index (highest resolution) image by using the sub-image number in square brackets after the filename:

-combine result.tif
I am working on a feature of an image conversion service, and I need to
scale an image - if the requested dimensions are bigger of the original image, it should not enrlage.
ImageMagick supports that, but when I use -density to improve quality of converted image (I convert from pdf to png) , the "do not enlarge" behavior does not work well.
examples:

I need to automatically convert PSD files with or without multiple layers into a TIFF LZW with only one layer, without noticeable differences.
Here is type of command I tried with Imagemagick 6.9.2-7 :
convert "fontaine_p7p.psd" -compress LZW -define tiff:endian=msb -background none -flatten fontaine_p7p.tif
Result is not as expected compare to the one obtained thanks to PhotoShop.
Layers are correctly merged, sizes of conversions are equivalent but I can see visible modifications on the Imagemagick tiff that are not visible on tiff generated thanks to PhotoShop.
Here are examples of a source PSD and the Tiff obtained via the imagemagick conversion above and where visible modifications are clearly iden :
PSD + TIFF + IdentifyVerbose
Here are details on PSD and TIFF files :

It seems that imagemagick is not handling transparency is the same way as Photoshop during conversion to Tiff.
Is somebody have proposition to have a better result with such kind of procedure ? I already tried to replace the ("-flatten" option by "-layers merge" but in that case the transparency background is completely lost.
Thanks in advance
I'm running the following, which is nearly correct:
convert joint/* \
-limit memory 512MiB \
-crop 2x1# +repage +adjoin \
-set filename:fn '%t-%[fx:p&1].%e' \
'separate/%[filename:fn]'
It splits each image in a directory of images into two images each. fx is used to alternate tile indices between 0 and 1. However, some image halves in the output directory are mysteriously missing:

Another edit: read https://bugs.launchpad.net/ubuntu/+source/imagemagick/+bug/1079813 and then http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=22387 - this is an ImageMagick bug.
According to the linked forum post, the only solution is to upgrade to ImageMagick 7.
