Please i'm working on a project using one of the regionization preset and i want the region i draw to be filled with the part of the image brush that best match or suits the source image. I'm using image folder brush and anytime i draw the region to be filled with the brush, it will be filled with parts that i dont want.

Then again i'm using RGB Mapping under the Brush control panel.

Could you please help me out.

If you are using RGB Mapping for you image folder brush indexing, then it's choosing the best color match from the set of images in the folder. Do you want the image to be selected differently then that (best color match)?

One thing to try. Look in the paint Color Source control panel. Near the bottom is a control called Override Color. Normally the color is generated from the path start point. So that would be occurring if the Override Color control is set to Off. But for path start regionization, it's often better to generate the color from a complete statistical sampling of the entire region. If you change Override Color to Regionize Color, then that will happen. That might give you better closest color since the color sampling will be taking place over all of the pixels in the generated region.

Hi thanks for the help, 

Again how can I make the brush (image folder brush) fill the canvas  to suit two different shades in the source image with a single dab of paint. (In this instance when using any of the pen modes that fills a region with color or image brush)

Can you explain this second question in more detail. I'm not sure what you are asking for?

For example I have a flower image colored red and yellow and I want the region I draw to show both red and yellow portions of the flower image and still have  the region i drew represent the source image.

Or some portions within the source image will require me to apply the brush twice ( i.e manually drawing two regions) on the canvas  as a result of different tones within the source image but would want the brush to fill such portions by drawing only one region.

Ok, i think i got it. SA5 movie brush or image folder brush indexing is focused on the aggregate properties of the entire region (or the entire movie frame or image being analyzed for placement). As opposed to trying to take into account localized statistical arrangement and match that up between the source image and localized components of the individual movie frame or images. We've thought about adding additional indexing options that would be better at what you want to do at some point in the future.

It's kind of a shame that Apple Computer goes out of their way to prevent you from running legacy software. Because the MSG Evolver application we used to ship with Studio Artist did have some indexing options that did what you want to do.

As far as normal painting trying to match bi-level color or shape statistics based on where it's being dropped in the canvas. That's an interesting idea. So i'll add it to things to think about for the future.

Most of the paint synthesizer features tend to go the opposite direction, like brush size modulation that tightens the nib to a specific color's position.

Hi, thanks for the reply. Really appreciate it.

This means for now its not possible to achieve that in SA be it on Mac or Windows. Or can I use the MSG Evolver to achieve it on PC. Please if possible how.

Again what brush size modulators tightens the brush nib to a specific color position. Thanks 

MSG Evolver was a mac only program. It also was written for PPC, not intel chips, which was the only option available when it was written. Apple used to provide an emulator that allowed PPC code to run on intel macs. They stopped supporting that, leaving their customers unable to run legacy applications.

Brush modulators are in the Brush Modulation control panel. Look under the large number of options available for Size Modulation control there. Specific Color position ones are pretty obvious (LocalLum Dif, LocalColor Dif, ColorRange, ColorRange at Radius).


 Pleas I'm having an old version of SA ( v3 and v4). Please can you show me the MSG imdexing options that can allow me to achieve the effect we discussed earlier on. 

Please I really need it because it will reduce the number of smaller tiles or shapes  which are very difficult to see and i can't  have large canvas size since I'm using Windows OS.


You should look in the MSG Evolver user guide if you want more information on how MSG Evolver works. Look at the art mapper functionality and how to work with it. There are probably some really old posts here on the forum associated with it buried in old archives. 

Again, MSG Evolver is a PPC mac only application. So i'm a little bit unclear how you are going to run it on an intel windows computer?

None of my macs will run it at this point since rosetta support was dropped a long time ago, and we don't have any ppc machines here at this point. They all died a long time ago.

Hi thanks for the update.

Please is there a way to achieve the effect created by the MSG evolver art mapper using path start  regionisation features of SA.


Here's a tip on simulating the MSG Evolver Art Mapper in Studio Artist. This was written when SA4 came out, so it's not including all of the SA5 path start regionization options.

The particular spatially localized indexing option i mentioned that was available in Evolver for art mapping is not available in SA5. The SA5 index attribute is computed over the entire movie frame or folder image. So RGB mapping in V5 is mapped based on the full color of the movie frame or brush image (and associated area mapped from the canvas into the source image).

We've thought about adding what you want for a future update.

You might do better using manual positioning of individual images for what you are currently trying to achieve.

I'm not sure i specifically understand the question you are asking here.

Are you referring to a single region in a path start regionization process? Or how the paint synthesizer works in general? Or?

If you are referring to a single region generated by path start regionization, are you referring to how it's generated, or how something like color mapping into it would work?

SA, If you add one option we can generate coloring book too.

Dear Synthetik Software, we have many options for filling, please add a new option:Put Color Number in regionWe can create perfect coloring book that there are not anywhere.please see this website as example for my meaning.See More
