This document covers frequently asked questions about Image Presets (also called image formats or macros).
When creating the Image Preset, add the following under the URL Modifiers:
layer=1&src=<>/<>&size=300,300
Save the Image Preset and Submit a publish job.
Here is an example Image Preset. The preset is called Layer_Ab.
Working example:
http://s7d9.scene7.com/is/image/TechSupport3/Jackie 5FOld?$Layer 5FAb$
Using req=resolve, you can see the layering commands that are set in the preset:
http://s7d9.scene7.com/is/image/TechSupport3/Jackie_Old?$Layer_Ab$&req=resolve
Image presets can reference IR images, as can templates. Or, you can also wrap entire IR requests inside IS requests to apply image-only presets.
http://s7d7.scene7.com/ir/render/renderCatalog/fileName_vignette?obj=objectID&src=is(renderCatalog/fileName?$adobeTest$)
Where vignette object is defined as objectID and adobeTest is a defined preset. You can replace the parenthesis curly brackets.
Note:
If you think you're running into this limit, check the length of the URL query string in the preset setup. The content after the ? has the limit of 512 characters.
For example:
wid=400&hei=400&fmt=jpeg&qlt=75,0&op_sharpen=0&resMode=bicub&op_usm=0.0,0.0,0,0&iccEmbed=0
The default parameters alone use 90 characters.
