editing an image operator

I had a question about editing an image operator. I have a large photo that I would like to work on in SA. For speed of testing/development of technique I began editing in SA at a small size/resolution. Once I found the preset I wanted to work with I created a new SA canvas at the size I wanted to print in high resolution and began to use the preset. Ofcourse the preset operates on this new much larger canvas/image in a different way. I've tried playing around with the editor to make it look more like the results I got at the samller size, but not much success. Can you offer any guidance for what to change using the editor? It seems the brush modulation editor would be place to start but not been able to make sense of/use well.

The quick way to resize a paint preset is to use the b hotkey. Hold down the b key, then mouse down in the canvas and dynamically resize it.

So what is that b key resizing doing?

If the preset is really simple, it might just be resizing the Brush Source control panel's horz and vert size controls.

But a lot of paint presets thee days are more elaborate under the hood.

There might be procedural textures associated with them, so the sizing of those procedural textures might be adjusted as well.

Of what you perceive as the brush might actually be multiple instances of a much smaller brush spatially randomized, or they could be moving in a live particle cloud. So this would be an example of a virtual brush.

In this case, you might want to adjust the spacing of the randomization or of the particle cloud while keeping the brush source size the same.

For some weird vector paint presets (or for region fill as brush pen mode), the max path length actually defines what you would perceive as the brush.

Again, the b key resize tries to be smart about it (although it doesn't always succeed).

We've tried to make it smarter over time. So if you run into paint presets that don't seem to size scale well, let us know about them. This is how we've made b hot key brush resizing smarter in the past.

Here's a tip on resizing the brush.
