Convert colors to RGB

Hello,

I need to color convert path items stroke/fill in CMYK colorspace to RGB colorspace - essentially the functionality given by Edit > Edit Colors > Convert to RGB.

In my code, I first select the path items. I then invoke the Convert to RGB menu action. However, nothing really happens. The colors stay in CMYK.

The document color mode is RGB.

// Select all paths

error = CollectPaths(&store, &count);

ai::int32 index = 0;

for (index = 0; index < count; index++)

{

     AIArtHandle art = (*store)[index];

     ai::int32 attr;

     error = sAIArt->GetArtUserAttr(art, kArtLocked | kArtHidden, &attr);

     if (!(attr & (kArtLocked | kArtHidden)))

     {

          error = sAIArt->SetArtUserAttr(art, kArtSelected, kArtSelected);

     }

}

// Invoke Convert To RGB

AICommandID convertCmd;

sAICommandManager->GetCommandIDFromName(kColors9CommandStr, &convertCmd);

error = sAIMenu->InvokeMenuAction(convertCmd);

This is what CollectPaths looks like:

ASErr CollectPaths(AIArtHandle ***store, ai::int32 *count)

{

     *store = NULL;

     *count = 0;

     AIMatchingArtSpec specs;

     ai::int16 numSpecs = 1;

     specs.type = kPathArt;

     specs.whichAttr = 0;

     ASErr error = sAIMatchingArt->GetMatchingArt(&specs, numSpecs, store, count);

     return error;

}

Any ideas why the menu action does nothing?

Is it in disabled state because of some reason?

Thanks,

MT
