trim set of images same amount

I've got a set of stills extracted from a video that I'd like to process the same way, but when I apply -trim to each still they are getting trimmed a tad different each time (when they should have the exact amount of black space on every still. Is there a way to get the average trim of a set and ap...

Re: create mask for constant (nonchanging) portion of video

@snibgo

Brilliant post. Can you format that code for linux / bash?

create mask for constant (nonchanging) portion of video

I have been a long time ImageMagick user, huge fan. This question is more about theory than syntax. I have a compressed ultrasound video clip that has a portion at the top (usually 25-75 pixels) that has personal patient information. I'd like to get this value automatically. This upper portion of th...

Re: crop a rotated box out of an image

snibgo,

I have run into an issue with this code. Specifically the cropping that happens with -distort when the line goes primarily horizontal (0,202) (792,280) is unacceptable. Is there any way to use +distort and know the location of the line?

crop a rotated box out of an image

Hello, I am having a hard time wrapping my head around this one. I have an image that the user is able to draw a 3px line across, and that line is extended to the edges of the image. What I'd like to do is crop the image to the pixels under the line and rotate them to have a 3px width portrait-orien...
