I thank for the answer!
Prompt and whether it is possible to make so in images?

Tell me, please, in the next issue. There is the original image with an alpha channel. https://habrastorage.org/files/7e4/422/0c5/7e44220c54d643b28e7d6b2479f292e6.png Tell me, how do I do it like this, while preserving the alpha channel of the image. https://habrastorage.org/files/3c7/5d9/935 ...

I mean to make a certain analog of gifsicle but on the basis of ImageMagick
i.e. I have gif the image with animation, I want it to optimize means of ImageMagick. as to me to make it.

The second question as the above-stated image is optimized

Good day! Now I am learning article - Animation Optimization . Tell me, how I can automate the optimization process animation in GIF images. -coalesce -layers Optimize How was optimized this image (I am unable to achieve this result). http://hsto.org/storage2/09e/482/07c ...

Thank you very much!

Read an article about SSIM, which is not in ImageMagic? they say it is better to use it to compare images. Tell me, is this so?

Tell me which option to use -metric type for the evaluation of visual changes image?

Thank you for your reply.I can't understand how you can obtain the coefficient of difference images?

Good evening! tell me how to use ImageMagick, you can visually compare two images and give a ratio difference images?

Thank you very much!

And the last question, how to make a picture like this?



How can I change the background to a picture are not white, and black?

Tell me, please , why not work? for %%i in (a0\*) do ( ImageMagick\convert ^ "%%i" ^ -alpha background ^ -alpha off ^ -transparent White ^ -compose DstOver ^ ( -clone 0 ) -geometry +1+0 -composite ^ ( -clone 0 ) -geometry +2+0 -composite ^ ( -clone 0 ) -geometry +4+0 -composite ^ ( -clone 0 ...

I figured, thank you very much. ImageMagick\convert ^ 1.png ^ -alpha background ^ -alpha off ^ -transparent White ^ -compose DstOver ^ ( -clone 0 ) -geometry +1+0 -composite ^ ( -clone 0 ) -geometry +2+0 -composite ^ ( -clone 0 ) -geometry +4+0 -composite ^ ( -clone 0 ) -geometry +8+0 -composite ...

I think you can do so ImageMagick\convert ^ 1.png ^ -alpha background ^ -alpha off ^ 2.png ImageMagick\convert ^ 2.png ^ -transparent White ^ -compose DstOver ^ ( -clone 0 ) -geometry +1+0 -composite ^ ( -clone 0 ) -geometry +2+0 -composite ^ ( -clone 0 ) -geometry +4+0 -composite ^ ( -clone 0 ...

Please tell me how this image http://habrastorage.org/files/1b6/788/35d/1b678835d869423fad330e2acb76b75d.png convert -alpha off http://habrastorage.org/files/aca/26f/eeb/aca26feeb69b49c19210ec1d57d63aa2.png made like this http://habrastorage.org/files/70c/c62/163/70cc6216369b478e8704d2e461cbb272.png ...

Figured out, I just used, that this image



And you can use the above image, to obtain the same result



But at the same time that the layer alpha channel is preserved?
