| * Description |
| * Constructs a Hardware Composer (HWC) list of frames from |
| * command-line specified parameters. Then sends it to the HWC |
| * be rendered. The intended purpose of this tool is as a means to |
| * reproduce and succinctly specify an observed HWC operation, with |
| * no need to modify/compile a program. |
| * |
| * The command-line syntax consists of a few standard command-line |
| * options and then a description of one or more frames. The frame |
| * descriptions are separated from one another via a comma. The |
| * beginning of a frame description requires the specification |
| * of the graphic format and then the display frame rectangle where |
| * the frame will be displayed. The display frame rectangle is |
| * specified as follows, with the right and bottom coordinates being |
| * exclusive values: |
| * |
| * [left, top, right, bottom] |
| * |
| * After these two required parameters each frame description can |
| * specify 1 or more optional attributes. The name of each optional |
| * attribute is preceded by a colon. The current implementation |
| * then requires white space after the colon and then the value of |
| * the attribute is specified. See the synopsis section above for |
| * a list of attributes and the format of their expected value. |
