20 * Synopsis
21 * hwcRects [options] (graphicFormat displayFrame [attributes],)...
22 * options:
23 * -D #.## - End of test delay
24 * -v - Verbose
25 *
26 * graphic formats:
27 * RGBA8888 (reference frame default)
28 * RGBX8888
29 * RGB888
30 * RGB565
31 * BGRA8888
32 * RGBA5551
33 * RGBA4444
34 * YV12
35 *
36 * displayFrame
37 * [left, top, right, bottom]
38 *
39 * attributes:
40 * transform: none | fliph | flipv | rot90 | rot180 | rot270
41 * blend: none | premult | coverage
42 * color: [0.##, 0.##, 0.##]
43 * alpha: 0.##
44 * sourceDim: [width, height]
45 * sourceCrop: [left, top, right, bottom]
46 *
47 * Example:
48 * # White YV12 rectangle, with overlapping turquoise
49 * # RGBA8888 rectangle at 30%% (alpha: 0.7) transparency
50 * hwcRects -v -D 30.0 \
51 * YV12 [50, 80, 200, 300] transform: none \
52 * color: [1.0, 0.5, 0.5], \
53 * RGBA8888 [100, 150, 300, 400] blend: coverage \
54 * color: [0.251, 0.878, 0.816] alpha: 0.7 \
55 * sourceDim: [50, 60] sourceCrop: [5, 8, 12, 15]
56 *
57 * Description
58 * Constructs a Hardware Composer (HWC) list of frames from
59 * command-line specified parameters. Then sends it to the HWC
60 * be rendered. The intended purpose of this tool is as a means to
61 * reproduce and succinctly specify an observed HWC operation, with
62 * no need to modify/compile a program.
63 *
64 * The command-line syntax consists of a few standard command-line
65 * options and then a description of one or more frames. The frame
66 * descriptions are separated from one another via a comma. The
67 * beginning of a frame description requires the specification
68 * of the graphic format and then the display frame rectangle where
69 * the frame will be displayed. The display frame rectangle is
70 * specified as follows, with the right and bottom coordinates being
71 * exclusive values:
72 *
73 * [left, top, right, bottom]
74 *
75 * After these two required parameters each frame description can
76 * specify 1 or more optional attributes. The name of each optional
77 * attribute is preceded by a colon. The current implementation
78 * then requires white space after the colon and then the value of
79 * the attribute is specified. See the synopsis section above for
80 * a list of attributes and the format of their expected value.
