|
|
* Pixmap geometry string interpretation : |
47 |
|
|
* Each geometry string contains zero or one scale/position |
48 |
|
|
* adjustment and may optionally be followed by a colon and one or more |
49 |
|
|
* colon-delimited pixmap operations. |
50 |
|
|
* The following table shows the valid geometry strings and their |
51 |
|
|
* affects on the background image : |
52 |
|
|
* |
53 |
|
|
* WxH+X+Y Set scaling to W% by H%, and position to X% by Y%. |
54 |
|
|
* W and H are percentages of the terminal window size. |
55 |
|
|
* X and Y are also percentages; e.g., +50+50 centers |
56 |
|
|
* the image in the window. |
57 |
|
|
* WxH+X Assumes Y == X |
58 |
|
|
* WxH Assumes Y == X == 50 (centers the image) |
59 |
|
|
* W+X+Y Assumes H == W |
60 |
|
|
* W+X Assumes H == W and Y == X |
61 |
|
|
* W Assumes H == W and Y == X == 50 |
62 |
|
|
* |
63 |
|
|
* Adjusting position only : |
64 |
|
|
* =+X+Y Set position to X% by Y% (absolute). |
65 |
|
|
* =+X Set position to X% by X%. |
66 |
|
|
* +X+Y Adjust position horizontally X% and vertically Y% |
67 |
|
|
* from current position (relative). |
68 |
|
|
* +X Adjust position horizontally X% and vertically X% |
69 |
|
|
* from current position. |
70 |
|
|
* |
71 |
|
|
* Adjusting scale only : |
72 |
|
|
* Wx0 Multiply horizontal scaling factor by W% |
73 |
|
|
* 0xH Multiply vertical scaling factor by H% |
74 |
|
|
* 0x0 No scaling (show image at normal size). |
75 |
|
|
* |
76 |
|
|
* Pixmap Operations : (should be prepended by a colon) |
77 |
|
|
* tile Tile image. Scaling/position modifiers above will affect |
78 |
|
|
* the tile size and origin. |
79 |
|
|
* propscale When scaling, scale proportionally. That is, maintain the |
80 |
|
|
* proper aspect ratio for the image. Any portion of the |
81 |
|
|
* background not covered by the image is filled with the |
82 |
|
|
* current background color. |
83 |
|
|
* hscale Scale horizontally, tile vertically ? |
84 |
|
|
* vscale Tile horizontally, scale vertically ? |
85 |
|
|
* scale Scale both up and down |
86 |
|
|
* auto Same as 100x100+50+50 |
