virtual L_BOOL LBitmapRgn::BitmapHasRgn()

Determines whether the associated class object's associated bitmap has a region.


Value Meaning
TRUE The specified bitmap has a region.
FALSE The specified bitmap does not have a region.


When a bitmap has a region, the LEADTOOLS functions that modify the pixel values (for example LBitmap::Posterize) act on the region, rather than the whole bitmap. In addition, the LEADTOOLS functions that flip, reverse, rotate, shear, or resize a bitmap also transform the region to match the bitmap. For example, if you were to shear the bitmap that had a rectangular region, the region would become a parallelogram.
