Canvas Size/Cropping Macro

[jaybray]

I have a series of screenshots I need to crop. Each image has the same width (1984 px), but the height varies from screenshot to screenshot.

I need to remove 687 px from the left and right sides (1374 px in total) resulting in an image that is 600 px wide. I don't need to remove anything from the top or bottom. Using the Crop Tool or Resize Canvas, I can achieve my desired results easily if I manually Crop/Resize each image individually. However, I'd prefer to set up a macro to do this more quickly. I cannot figure out how to build a macro that removes the needed amount from the left and right while ignoring the height differences with each image.

Thanks in advance for any ideas.

Not sure this can be done at all with the APh macro facility, since it usually doesn't work/records macros in a dynamic size independent manner. In your case as you have a constant fixed width adjusting the left/right side decrement accordingly wouldn't be maybe that much of the problem here (if cropping always does work initially from a center position then), but instead taking the different possible heights dynamically into account might be problematic.

In contrast to APh you can also take a look at ImageMagick which offers quite more options here and can be easily used for batch processing too.

Ok, thanks.

I have access to Photoshop which offers the functionality I need on this. I just prefer using Affinity products whenever possible.

In PS it should be easy to do, either via an ATN action or scripting, same with Gimp etc.

Whoa @carl123 — this is slick. This appears to be working. I'll need to spend some time analyzing how you did this.

I really appreciate your time and assistance. 

⭐⭐⭐⭐⭐ for you.

Yes, @carl123, I would really love to know how you did that.

I thought this was an easy one ☺️

The final size of the image is always 600px width

So, I just created a rectangle 600px width by 3000px height (3000px just to cater for the largest anticipated image)

Then just arrange the rectangle to the middle of the document

Arrange > Align Centre
Arrange > Align Middle

Clip the image with the Rectangle to get a 600px width image (variable height depending on the original image)

Then just tidy up with...

Clip canvas / rasterise & trim
