38 | * 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 |
|
|
60 | * auto Same as 100x100+50+50 |
