This method is similar to the DocumentBlobRemoval Method, but uses the default settings.

ImagXpress removes only black images on a white image. To remove white pixels on black image requires prior processing, to negate the bitonal image. You can specify a subset of the image to speed processing time and limit unwanted blob removal.

The image is examined for the blobs, such as the black holes left on copies by binder hole punches in the original image. Blobs within the specified region are removed from the current image.

ImagXpress finds black blobs meeting the specified minimum pixel count and yet not exceeding the specified maximum pixel count. The removed blobs are replaced with white pixels. Without a set detection area, the entire image is examined and updated if it meets the criteria. If a blob is detected on the boundaries of a sub-image, only the portion of the blob within the boundaries is removed.

Outputs

• The current image is modified, with blobs removed as specified. If the operation fails, no change is made to the image.
• The IPCountofObjectsFound property indicates the number of objects meeting the specifications.
• The IPImagewasModified property indicates whether the image was changed.

Using DocumentBlobRemoval method

1. Load a 1-bit image containing a black image on white.
2. Call DocumentBlobRemovalUsingDefaults method.
3. Examine IPCountOfObjectsFound and IPImagewasModified properties for information current image no longer has blobs.

Note: Available in Professional Edition.
