Need clarification about Channel Ports Suite

[marcoolivotto]

Dear forum members,

about a year ago someone asked the following:

>Like say I wanted to call Gaussian Blur that photoshop already has, are there functions to do this?  Or would I have to create my own Gaussian Blur?

to which Chris Cox replied:

>Yes, from automation plugins or scripts. From other plugins: no, you'd have to create your own.

OK. But then, what is the ApplyOperation routine in the Channel Ports Suite about?

The PoorMans Type Tool plug-in included in the sample code does exactly this, Gaussian Blur - and it's a filter. Or am I missing something? If I load the relevant data from a port, process them and write them to an out port, it might work... or not?

To be honest, I am about to write my own GB routine, because the Channel Ports Suite stuff is not exactly straightforward to understand, but I am just guessing.

Many thanks in advance,

Marco Olivotto

Yes, you should be able to use the channel port operation to get a Gaussian Blur. I believe the Poor

Mans example does not actually use the results of the Gaussion Blur from Photoshop but it does use that operation. Y

ou should be able to work the code around to get the GB result from the operation and then apply your filtering to the output of  PS_GB.
