Merge Selected without Trimming


Recommended Posts

Group both layers, and use rasterize.

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.

Please keep in mind to check layer size, position, rotation etc. you should add one extra step and rasterize the lower layer before merging them in case of:

  1. fractional position
  2. Layer DPI not matching documnet DPI
  3. layer rotated or sheared.

otherwise result of merge will be blurry.

so in general to be safe:

  • rasterize lower layer
  • group both layers
  • rasterize group

I've been curious about that recommendation. Often, the lower layer will be the background layer, and by definition it has the proper DPI and is aligned to the grid. So why would rasterizing it help?

you are safe when opening a file via „open“.
In case the layer is created by „place“ or „pasted“ into an exiting document it is often misaligned, or will be enlarged or reduced.
