To crop an image automatically
Select an image on the screen and run the operation in one of the following
ways:
Click the Crop Auto button on the Raster Image toolbar.
Choose Crop in the rImage menu, then Crop/Crop/Auto.
- or -
Start the operation without selecting an image.
Select an image you want to process from the dialog box.
The program automatically finds empty areas in the image and crops them.
To obtain optimal results it is recommended that you apply the deskewing
procedure or four-point correction before cropping.
Cropping by frame
If the image has a frame, then this command automatically resizes document to the
frame size, ignoring insignificant speckles and sometimes even small objects and
texts.
Note that since autocropping by frame is completely automatic, a skewed frame
and/or too many speckles on the image can spoil the results. It would be a good
idea to apply rImage > Deskew and/or rFilters > Speckle Remover to the image
before autocropping by frame.
To crop image by frame
Select an image on the screen and run the operation in one of the following ways:
