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