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.
| 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. |
