| This module is rated as ready for general use. It has reached a mature form and is thought to be bug-free and ready for use wherever appropriate. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing. |
This module contains very few code - but it is heavily used.
It is needed to verify that a given display size is trailed by "px".
It can be expanded to check for other dimensions, as e.g. "em".
it will be used by Template:F, Created with/layout, ...
Use it with e.g. {{#invoke:Dsize|main|{{{sizepar}}} }}
| {{#invoke:Dsize|main|72px}} | 72px | width |
| {{#invoke:Dsize|main|72}} | 72px | width |
| {{#invoke:Dsize|main|72x}} | 72xpx | width |
| {{#invoke:Dsize|main|x64px}} | x64px | height |
| {{#invoke:Dsize|main|72x64}} 0 | 72x64px 0 | w × h |
Module:Galeria has a similar but more powerful and complex function.
