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) |
