Cropping image on non-transparent background


Recommended Posts

I've inset and centred an image on a white canvass background, with the intent of outputting the entire canvass and having the image framed with white borders all around.  I want though to crop the actual image a bit -- but when I select it and click on the crop tool, it wants to crop the canvass instead(!).  How do I crop an image on a non-transparent background/canvas?

Do you use Photo?
The crop tool intentionally crops the canvas.

To crop an image (layer inside document), just add a rectangular shape, fill in white, and nest to the masking position of that layer (hover over the layer thumbnail picture and drop it there).

The use the move tool to adjust the size as needed.

Use Snapping / pixel alignment.

My posts focus on technical aspects and leave out most of social grease like „maybe“, „in my opinion“, „I might be wrong“ etc. just add copy/paste all these softeners from this signature to make reading more comfortable for you. Otherwise I’m a fine person which respects you and everyone and wants to be respected.

You could try using a Rectangle as a Mask for the image.

I have never mastered color management, period, so I cannot help with that.

Many thanks.  The rectangular mask probably the easiest and will retain image data best.

 I tried other workarounds -- but I also found that after cropping an image, copying and pasting or resizing eliminates the crop.  Why?   How do you make a crop permanent so that further modifications adjustments don't reset the crop?
