|
|
* 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.
