* Pixmap geometry string interpretation : |
31 |
* Each geometry string contains zero or one scale/position |
32 |
* adjustment and may optionally be followed by a colon and one or more |
33 |
* colon-delimited pixmap operations. |
34 |
* The following table shows the valid geometry strings and their |
35 |
* affects on the background image : |
36 |
* |
37 |
* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%. |
38 |
* W and H are percentages of the terminal window size. |
39 |
* X and Y are also percentages; e.g., +50+50 centers |
40 |
* the image in the window. |
41 |
* WxH+X Assumes Y == X |
42 |
* WxH Assumes Y == X == 50 (centers the image) |
43 |
* W+X+Y Assumes H == W |
44 |
* W+X Assumes H == W and Y == X |
45 |
* W Assumes H == W and Y == X == 50 |
46 |
* |
47 |
* Adjusting position only : |
48 |
* =+X+Y Set position to X% by Y% (absolute). |
49 |
* =+X Set position to X% by X%. |
50 |
* +X+Y Adjust position horizontally X% and vertically Y% |
51 |
* from current position (relative). |
52 |
* +X Adjust position horizontally X% and vertically X% |
53 |
* from current position. |
54 |
* |
55 |
* Adjusting scale only : |
56 |
* Wx0 Multiply horizontal scaling factor by W% |
57 |
* 0xH Multiply vertical scaling factor by H% |
58 |
* 0x0 No scaling (show image at normal size). |
59 |
* |
60 |
* Pixmap Operations : (should be prepended by a colon) |
61 |
* tile Tile image. Scaling/position modifiers above will affect |
62 |
* the tile size and origin. |
63 |
* propscale When scaling, scale proportionally. That is, maintain the |
64 |
* proper aspect ratio for the image. Any portion of the |
65 |
* background not covered by the image is filled with the |
66 |
* current background color. |
67 |
* hscale Scale horizontally, tile vertically ? |
68 |
* vscale Tile horizontally, scale vertically ? |
69 |
* scale Scale both up and down |
70 |
* auto Same as 100x100+50+50 |
