Function: linear_blend
|
|
|
|
--Usage--
|
|
> linear_blend(
|
|
> image1: image, image2: image,
|
|
> x1: coordinate, y1: coordinate,
|
|
> x2: coordinate, y2: coordinate,
|
|
> )
|
|
|
|
Blend two images together using a linear gradient.
|
|
|
|
Coordinates range from 0 to 1, where 0 is the top and the left, and 1 is the right and the bottom.
|
|
So for example a blend from @x1:0, y1:0@ to @x2:0, y2:1@ is from top to bottom.
|
|
|
|
The images must have the same size.
|
|
|
|
--Parameters--
|
|
! Parameter Type Description
|
|
| @image1@ [[type:image]] First image to blend
|
|
| @image2@ [[type:image]] Second image to blend
|
|
| @x1@,@y1@ [[type:double]] Coordinates where the gradient begins, and the first image is shown for 100%
|
|
| @x2@,@y2@ [[type:double]] Coordinates where the gradient ends, and the second image is shown for 100%
|
|
|
|
--Examples--
|
|
This gives a vertical gradient:
|
|
> linear_blend(image1: "image1.png", image2: "image2.png", x1:0, y1:0, x2:0, y2:1) == [[Image]]
|
|
>>> linear_blend(image1: <img src="image1.png" alt='"image1.png"' style="border:1px solid black;vertical-align:middle;margin:1px;" />, image2: <img src="image2.png" alt='"image2.png"' style="border:1px solid black;vertical-align:middle;margin:1px;" />, x1:0, y1:0, x2:1, y2:1) == <img src="image_linear_blend.png" alt='"image_linear_blend.png"' style="border:1px solid black;vertical-align:middle;margin:1px;" />
