* Pixmap geometry string interpretation : |
61 |
* Each geometry string contains zero or one scale/position |
62 |
* adjustment and may optionally be followed by a colon and one or more |
63 |
* colon-delimited pixmap operations. |
64 |
* The following table shows the valid geometry strings and their |
65 |
* effects on the background image : |
66 |
* |
67 |
* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%. |
68 |
* W and H are percentages of the terminal window size. |
69 |
* X and Y are also percentages; e.g., +50+50 centers |
70 |
* the image in the window. |
71 |
* |
72 |
* Pixmap Operations : (should be prepended by a colon) |
73 |
* tile Tile image. Scaling/position modifiers above will affect |
74 |
* the tile size and origin. |
75 |
* propscale When scaling, scale proportionally. That is, maintain the |
76 |
* proper aspect ratio for the image. Any portion of the |
77 |
* background not covered by the image is filled with the |
78 |
* current background color. |
79 |
* hscale Scale horizontally, tile vertically ? |
80 |
* vscale Tile horizontally, scale vertically ? |
81 |
* scale Scale both up and down |
82 |
* auto Same as 100x100+50+50 |
