Template:Scale/doc
The {{scale}} affine transform template scales an element about a given origin (reference point, from left top of the element's bounding box), which defaults to the center of it's bounding box.
Contents
Usage
- {{scale|element to scale|sx = sx (default: 1.0)|sy = sy (default: sx)|origin = origin (default: 50% 50%)}}
or
- {{scale|element to scale|sx (default: 1.0)|sy (default: sx)|origin (default: 50% 50%)}}
with parameters
- sx:
scaling factor, where sx is a real number (default: 1.0);x - sy:
scaling factor, where sy is a real number (default: sx);y - origin: fixed point about which the scaling is done as top left, top right, bottom left, bottom right, center or nn% nn% as percentage of height and width from left top corner of the element's bounding box (default: 50% 50%).
Examples
Examples with valid input

Scaling an image (with default origin, i.e. at center of image box)
The image File:WalkingTheCircle.png (326 × 296 pixels 2), shown via the code
{{canvas|width = 350|height = 350|units = px|{{image|Clockface.png}}}}
yields
| |
scaled 1.0 (i.e. 100%, no scaling) with the code
{{canvas|width = 350|height = 350|units = px|{{scale|{{image|Clockface.png}}}}}}{{-}}
yields
| |
and scaled 0.5 (i.e. 50%) with the code
{{canvas|width = 350|height = 350|units = px|{{scale|{{image|Clockface.png}}|0.5}}}}{{-}}
yields
| |
and scaled 0.25 (i.e. 25%) with the code
{{canvas|width = 350|height = 350|units = px|{{scale|{{image|Clockface.png}}|0.25}}}}{{-}}
yields

More elaborate examples
Works properly: Observe the difference between scaling before translating (e.g. the dotted gold pentagons) and translating before scaling (in which case the scaling is done relative to the center of the polygon before it was translated, because the origin used for scaling is not translated) (e.g. the solid red pentagons, scaled relative to the bottom left corner of the canvas, the center of the pentagons before translation).
