ImageGear Professional DLL for Windows
enumIGOrientationModes

Identifies how the image is oriented before it is drawn on the output device. Possible values are determined by the constants of the form IG_DSPL_ORIENT_X_Y, where each of X and Y can be LEFT, TOP, RIGHT or BOTTOM. X represents the position of the topmost row of the bitmap after applying the transformation. Y represents the position of the left-most column of the bitmap after applying the transformation.

For example, IG_DSPL_ORIENT_RIGHT_TOP means that the left-most column becomes the image's new topmost row, and that the topmost row becomes the image's new right-most column. The image, therefore, is rotated on 90 degrees.

Values:

IG_DSPL_ORIENT_BOTTOM_LEFT The image is flipped vertically.
IG_DSPL_ORIENT_BOTTOM_RIGHT The image is rotated 180 degrees.
IG_DSPL_ORIENT_LEFT_BOTTOM The image is rotated 270 degrees.
IG_DSPL_ORIENT_LEFT_TOP The image is rotated 270 degrees and then flipped vertically.
IG_DSPL_ORIENT_RIGHT_BOTTOM The image is rotated 90 degrees and then flipped vertically.
IG_DSPL_ORIENT_RIGHT_TOP The image is rotated 90 degrees.
IG_DSPL_ORIENT_TOP_LEFT The image is displayed unchanged.
IG_DSPL_ORIENT_TOP_RIGHT The image is flipped horizontally.
