unfortunately that is not exactly what I need. What I need is image.ini related problem. In this file you could define Filters[] ie. command line commands for imageMagick. In filter definition you could use parameters. Then in [image class] section in this same file you could define the use filters and provide values for attributes. However as I see the actual value of attribute must be provided in image.ini. My question is if there is any way to provide the value in template and get image generated with that value of parameter
So, you are thinking of doing something like specifying the size of the image from the template. As far as i know, there is no way to do what you want without changing the kernel/libraries.
