When I insert an image into a LO Writer document and then crop parts of the image, the orginal image is still part of the document and can be restored any time using right clip + “properties > (tab “crop”) > original size” (translated from German LO). This could be a problem regarding file size + data protection in general, but also leads to unwanted effects (e.g. with right click > compress) etc.
In this case I made a screenshot from LO Writer window, changed it to “anchored as character” and cropped it, so that the image only showed an icon in the icon bar.
I’m looking for a way to permanently remove the cropped parts of the image - like function “compress” does in MS Word 2016 (but obviously not in LO Writer 6.3.4.2 30 / Linux Mint 19.2 / both in German).
Always optimize the images before you insert them into an ODF document. Use third party free (or non-free) image editors.
Within LibreOffice you have two options.
Example Screenshot- you crop the image.
Then right-click on the crop and choose “Save” from the context menu.
Confirm that only the selection is saved.
- select the cropped image and choose
File>Export
from the menu. Click on “Selection” in the dialog and select PNG.
Otherwise follow the suggestion of @Zizi64
Quick workaround
You easily can really (!) crop an image… in Draw.
Procedure:
-
Insert image (as image/bitmap) in Draw
-
Crop image - cut/copy into clipboard
-
Insert
(paste special)
from Clipboard into Draw or Writer as a bitmap -
The originally hidden parts of the image are removed
Otherwise use @Zizi64 's procedure. In many/most cases a good hint. If you want to export your documents into PDF format I strictly recommend not to use simply cropped images but to use really cropped ones.
