Hole Remover

Hole Remover

This filter removes low-sized holes in raster objects. Only holes with size less than the specified value are removed. The filter can automatically estimate the hole size on image objects.
The filter can be used after such procedures as binarization and layering to fill undesirable holes in raster images.

To remove low-sized holes

1. Define the selection set to process and choose Hole Remover from the Filters menu or press the button on the Filters toolbar.

2. Specify the maximum size of raster holes to be removed in the current units (left box) or in dots (right box).
- or -
Set the Auto Estimating option so that the filter automatically estimates raster hole size before filtration.
To measure raster hole size on the screen, click on a pixel inside the object.
- or -
Click the button and pick two pixels on the screen. The program will estimate hole size equal to the distance between these pixels.
3. Choose Apply.
