History
ColdFusion 8: Added this function.
Parameters
| Parameter | Description | ||
|---|---|---|---|
| name | Required. The ColdFusion image on which this operation is performed. | ||
| transpose | Optional. Transpose the image:
|
180 | 270"- Rotate an image clockwise by 90, 180, or 270 degrees. |
Usage
If you do not specify the transpose parameter for the ImageFlip function, the image is transposed on a vertical axis, creating an image that is an upside-down version of the source. Use the ImageSetAntialiasing function to improve the quality of the rendered image.
