Sample Output

So, I have two images that are nearly identical, the alpha channel should be the same between both images, but one of the images has a white background and the character has a different color, while the other image has a transparent background. Other than that, the alpha channel should be the same b...

What I want it to do for the pixels in between is morph the images together so it looks seamless rather then fade/blend the images together. Put this another way: you have two images, as if a camera viewed a scene from two positions. You want each row of the output to be as if viewed from intermedi...

So, what I want to do is use composite to compose two stereoscopic images together so the top row of pixels display the left side image and the bottom row of pixels display the right side image. Here's what I did. 1.I have 2 720x720 stereoscopic images where one is the left camera and the other is t...

So, I have an animation I rendered twice, one where it's in a map of daytime and one in a nighttime equivalent map. The animation has frames numbered ani1_000000 to ani1_007199 for both daytime and nighttime. What I want to do is generate an entirely new set of images where at the beginning it's day...

Let's say I have a grayscale version of the image, and 2 of the color channels. Assuming that the fx command below was used to generate the grayscale, how can I recreate the third channel and piece the channels together in one command?

So, here's what I want to do. Let's say I have a normal image with RGB color channels. I want to either generate or use a random noise image for this. Basically, what I want to do is switch the red and green color channels based off the noise image's pixels. If the pixel is black the colors aren't s...

Looks like I found an image with the same color differences, it wasn't a result of my friend editing it. Here is my ImageMagick and System Info: Distributor ID: LinuxMint Description: Linux Mint 18.2 Sonya Release: 18.2 Codename: sonya Version: ImageMagick 6.8.9-9 Q16 x86_64 2017-05-26 http://www.im...

So, I had an image I wanted my friend to edit. He edited the image and sent it back to me. When I opened it however, I noticed that the colors in the altered image were slightly different than the original even in areas where no edits were made. So, what I want to do is alter the edited image's colo...

What I want to do is convert both images to greyscale, and render an output image which has values that are the absolute difference between the two input images. code in1.png in2.png -colorspace Gray -compose Difference -composite out.png Also, How can I extract a semi-transparent overlay from an i...

So, let's say I have 2 images. Both are identical, except one has a semi-transparent overlay placed over it. What I want to do is convert both images to greyscale, and render an output image which has values that are the absolute difference between the two input images. Also, How can I extract a sem...

So, I have a transparent image, and I want to outline it with it's own colors. I want the color of each pixel to be determined by the pixels next to it, with semi-transparent pixels having less effect than fully opaque pixels, and fully transparent pixels having no effect at all. Unfortunately, I ca...

So, let's say I have an image, and I want to invert the hue, but not the lightness. I know this command will produce the same result, but I'm looking for a simpler command. convert "input.png" -negate -colorspace Lab ^ -channel R -negate +channel ^ -colorspace sRGB "hue_invert.png&quo...

So, I want to generate a start button for the LXDE menu similar to that of the Windows XP Zune Theme but with custom text. Here is an image of the Zune theme: https://skattercdn.azureedge.net/files/2006/11/windowszunetheme.png The image doesn't have to be 100% accurate, just needs to look similar wi...

Sorry, but I do not understand your description of what you want to happen. Perhaps you can provide the full image that you start with and explain in more detail with diagrams if possible. When you say H do you mean the height of 384 or 48? If you know how to clone it twice, what is the code you us...
