Tutorial: non destructive cropping
Background
I don't like cropping through document mode: switching back to layer mode ends up in loosing the crop.
I know for many of us it is not an issue, but I figured out a way that works better for me.
Procedure
1. select the grid tool: set a 3x3 grid with black fill and white borders
2. select the top layer and draw a grid, so it will be placed as the first layer
3. change the blending mode to Lighter color
4. in the menu choose Layer --> Clipping Layer --> Clip Previous: you will be able to see just the portion of the image inside the grid, and the rest will be painted as transparent
5. use the layer handles to adjust the crop. If you want a fixed ratio, set up the horizontal and vertical sizes in the layer properties. To retain the ratio remember to scale the layer while holding shift
6. once the crop is done, set the borders of the grid as transparent (important to not affect the colors in the image)
7. if you want to hide the crop shift click on the visibility icon of the layer and use ctrl+6 to hide the layer handles
Commit the crop
1. with the crop clipping layer visible select Layout --> Document --> Trim Document: it gets rid of the transparency and resizes the document around the visible frame
2. export the image
Advantages
1. not very difficult to remember once you tried a couple of times
2. the crop is identified by a vector graphic, modifiable in the future simply adjusting the grid
Disadvantages
So far only one: remember that the trim is destructive, so don't save it along with the pld file: just before exporting
It seems is working for me, but I came up with this idea just yesterday .. any comment is welcome.

Re: Tutorial: non destructive cropping
Just a remark: if you crop in document mode and want to retain the document size when switching back to picture mode (not sure why one would want to do that), you can:
1) Create a new layer, choose "Document" under Position/Size, same colour mode as your current background layer (this will be selected automatically when the background layer is the active layer)
2) Move it to the back (make it the new background layer)
3) Switch back to Picture Mode.
No need to trim the image before exporting it, no risk forgetting to undo the trim. I guess that one could easily wrap this all up in a "Crop in Document Mode" action.
Cheers

Re: Tutorial: non destructive cropping
Works here. You'll have to crop in document mode first, then create the new background layer (which should then have the same size as the cropped image).sovereign hat geschrieben:Nice trick !

Not here. I just refer to the crop setting, not the document size: when I switch back to document mode the crop is lost.bkh hat geschrieben:Works here.

Re: Tutorial: non destructive cropping
Not sure what you mean. If you just want the previous crop rectangle, do Edit -> Select All (Cmd-A).sovereign hat geschrieben:Not here. I just refer to the crop setting, not the document size: when I switch back to document mode the crop is lost.

Re: Tutorial: non destructive cropping
Nope, for me it doesn't work: I did what you described. Then if I go to picture mode and, after that, in document mode again the original crop is lost.bkh hat geschrieben:Not sure what you mean.

Also, using the straighten tool blocks (in my case) the possibility to switch back to picture mode. Maybe a bug ?

Try my sample document (attached). Switch to document mode, select the crop tool and do Edit -> Select All.sovereign hat geschrieben:Nope, for me it doesn't work: I did what you described. Then if I go to picture mode and, after that, in document mode again the original crop is lost.
No problem here. Looks like something's wrong with your new background layer – if the distorted layer is still the bg layer, you can't switch to picture mode.sovereign hat geschrieben: Also, using the straighten tool blocks (in my case) the possibility to switch back to picture mode.

Re: Tutorial: non destructive cropping
Hi Burkhard, thanks for the example.
I still have both the issues
Perhaps something on my system ?

Re: Tutorial: non destructive cropping
Very strange. I'm on OS X here, maybe somebody else with Windows can try this?sovereign hat geschrieben:Hi Burkhard, thanks for the example.

1) download "crop sample.pld"
2) try if you can switch to document mode (in the document attributes panel)
3) if 2) works, choose the Crop tool and Edit -> Select All. Only a rectangular area in the middle should be selected. If "Hide Border Content" is off in the View menu, the screen should show something like this if zoomed at ≈60% Thanks,
Burkhard.

Re: Tutorial: non destructive cropping
No answer yet, so I tried it on my old XP installation. It works fine and I see no reason, why Windows and Mac OS should behave differently.bkh hat geschrieben:Very strange. I'm on OS X here, maybe somebody else with Windows can try this?
