Custom transformation presets
If you wish to apply the same transformations on many images, you can define presets and apply transformations only using the preset name (X).
p=X
Any resizing transformation or image filter can be included in a preset, as well as watermarks and image compression parameters.
Defining presets
You can define your presets in the admin panel, Image Settings / Presets.
Using presets
Sample presets
| preset name | operations and filters |
|---|---|
| gallery_thumb | w=250&h=250&f=gray |
| gallery_medium | w=450&h=300&force_format=jpeg&q=85&radius=10 |
| gallery_large | w=1200&force_format=jpeg&optipress=2&wat=1&wat_gravity=northwest&wat_scale=60&wat_pad=20&wat_opacity=0.4 |
Here are a couple of images using the sample presets shown above.
An operation defined in any given preset cannot be overridden in the URL. For example, if a preset named small_img contains w=200, using /original_image_url?p=small_img&w=400 will still yield a 200-pixel-wide image.
