Impress/Draw have two crop uno commands, one an simple and elegant interactive cropping tool (.uno:Crop) and the other a dialog (.uno:GrafAttrCrop). Writer has similar dialog cropping facility within one of the tabs of .uno:GraphicDialog and it would be great if an uno command could be created that would open of the dialog and jump to the crop tab, while we patiently wait for .uno:Crop to be added to Writer (bug 34555). I would like to integrate this newly created crop uno command into the image toolbar and image context menu and am assuming it would take less to create this than fix the .uno:Crop global availability.
Full crop functionality has been implemented in bug 34555.
