* Pixmap geometry string interpretation : |
39 |
* Each geometry string contains zero or one scale/position |
40 |
* adjustment and may optionally be followed by a colon and one or more |
41 |
* colon-delimited pixmap operations. |
42 |
* The following table shows the valid geometry strings and their |
43 |
* effects on the background image : |
44 |
* |
45 |
* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%. |
46 |
* W and H are percentages of the terminal window size. |
47 |
* X and Y are also percentages; e.g., +50+50 centers |
48 |
* the image in the window. |
49 |
* |
50 |
* Pixmap Operations : (should be prepended by a colon) |
51 |
* tile Tile image. Scaling/position modifiers above will affect |
52 |
* the tile size and origin. |
53 |
* propscale When scaling, scale proportionally. That is, maintain the |
54 |
* proper aspect ratio for the image. Any portion of the |
55 |
* background not covered by the image is filled with the |
56 |
* current background color. |
57 |
* hscale Scale horizontally, tile vertically ? |
58 |
* vscale Tile horizontally, scale vertically ? |
59 |
* scale Scale both up and down |
