)

Parameters

Flags
Algorithm

Borders are dark areas along the edges of the image. Borders can be present on one or more sides of the image. Deskew angle is a dominant angle of the lines between the borders and inner area of the image.

If Flags = ciBexBorder border area pixels are set to white
If Flags = ciBexBorderDeskew border area pixels are set to white and whole image is deskewed.
If Flags = ciBexBorderDeskewCrop border area pixels are set to white and image is deskewed. Then image is cropped along the lines between former border and inner area.
If Flags = ciBexDeskewCrop image is deskewed, then cropped along the lines between former border and inner area. Remnants might remain on the image.
