Core Image Patch Template

M.Oostrik's picture

Hi everyone

Last year i created a Core Image filter for Quartz Composer, based on the Paul Bourks article Edge blending using commodity projectors

For ease of use I'd like to make it into a custom patch, but being a novice in this field I didn't succeed so far. I was wondering if there is a template available, or if somebody can help me in any way.

Here is the filter.

with regards, Matthias

templates

There's a built-in template for using the supported API. We've also got a template for the unofficial api (what we use).

For just a core image filter, making a plugin probably isn't too helpful. It might be easier to use, but there will be a tiny performance hit, and users will need to install it before they can use compositions that make use of it (whereas core image filters just work everywhere).

Makes much sense

This means I'm finished with the project, thanx ;-)

silly question

How do I install the CI filter into my library? I really need to get my head around where everything goes with qc. I can add it to library as a macro, but I've noticed other people's comps have this patch as a ci filter on its own.

Re: silly question

Either

save the macro composition, put it in ~/Library/Graphics/Quartz Composer Patches. The macro will then appear in the Patch Creator.

Or

10.6.x or later, create a Virtual Macro. Select patch[es] to turn into a Virtual Macro, go to Editor menu, click "Add to Library". You can then fill in the name, copyright and description & boom - immediately added to Library.

The first type of macro is good for 10.5.x and higher. The latter is good only for 10.6.x & higher.
