This can be a pain to find so here is the quick access version:
<width>x<height><specifier>
| Specifier | Meaning |
|---|---|
| % | Interpret width and height as a percentage of the current size. |
| ! | Resize to width and height exactly, loosing original aspect ratio. |
| < | Resize only if the image is smaller than the geometry specification. |
| > | Resize only if the image is greater than the geometry specification. |
