So, apparently I have a chest image that I want to extend. I use ImageMagick 6.9.3-4 on Windows, but I'd also appreciate having the Linux Bash syntax for the command as well. The chest image i'm testing with is a strip of 576x384 for a video game, with each sprite being 48x48. Here's what I need to ...

So, I'm trying to edit an old game and import a custom character. I have an image of the palette I need to use, and the images of the character. I use this command to apply the palette, but there seems to be a problem with the resulting image when I try to import it into the game. cv -gravity south ...

So, I have 2 nearly identical images, except one has a semi-transparent overlay with a known color. Let's say Image A has the overlay, Image B is Image A without the overlay, and Image C is the overlay itself, which is the result I am trying to achieve.

You seem to want a simple chop and resize. Windows BAT syntax: %IM%co...

Yes, that is correct, but I don't know the command the achieve the desired result.

So, let's say I have 2 images, what I want to do is try to get the hard light from an image using an image with the effect applied and an image without the effect, so if I were to apply the effect itself to the image without the effect I'd get the image with the effect. Here's what I'm talking about...

That did not work, it just made the entire image transparent.

Plus, I am trying to remove a known background of an image that has a transparent foreground.

I don't understand. If you remove the original image apart from the transparent foreground, what are you left with? Example images might help. Please also read the IMPORTANT: Please Read This FIRST Before Posting thread. Basically, you remove the original image from the modified image and you're le...

So, I have an original image and a modified version of the same image with a transparent foreground. Both images (including the foreground in the modified image) seem to have transparency.
