Howdy,
Is it possible to colorize the object icons in the Object Manager, like the native joints in R13+?
I did a search for "colorize icon" but came up with nothing.
Adios,

Hi Dan,
It is possible, we did this in our original release of X-Particles. The user could choose a colour from a description element and colorize an object's icon with that. It worked fine, but we dropped it in later versions - I can't remember why now!
What we did was have a monochrome image for the object icon. Then the user colour was multiplied into that to recolour the icon. The code from Message() in the ObjectData plugin looked like this:
Bool XSystem::Message(GeListNode *node, LONG type, void *data)
{
BaseDocument *doc;
BaseContainer *nodebc;
BaseObject *op = (BaseObject* )node;
LONG x, y;
GetCustomIconData *cid;
UWORD r, g, b;
Real pixr, pixg, pixb;
Filename sysic;
Vector colicn;
nodebc = op->GetDataInstance();
doc = node->GetDocument();
switch(type)
{
case MSG_GETCUSTOMICON:
cid = (GetCustomIconData* )data;
if(cid)
{
colicn = nodebc->GetVector(XOVM_ICONCOLOR); // description COLOR element
GetIcon(OXPSystemIcon, cid->dat); // OXPSystemIcon registered in main.cpp
sysic = GeGetPluginPath() + Filename("res") + Filename("sysicon.tif"); // monochrome icon for this object
// sysbm is a BaseBitmap class-level variable AutoAlloc'ed in the class definition
if(sysbm && sysbm->Init(sysic) == IMAGERESULT_OK)
{
for(y = 0; y < 32; y++)
{
for(x = 0; x < 32; x++)
{
sysbm->GetPixel(x, y, &r;, &g;, &b;);
pixr = Real(r) /255 * colicn.x;
pixg = Real(g) / 255 * colicn.y;
pixb = Real(b) / 255 * colicn.z;
r = (pixr * 255);
g = (pixg * 255);
b = (pixb * 255);
sysbm->SetPixel(x, y, (LONG)r, (LONG)g, (LONG)b);
}
}
cid->dat->bmp = sysbm;
cid->filled = TRUE;
}
}
break;
//.... etc.....
The crucial things are the monochrome icon to start with and that you must be able to get its bitmap. I registered the icon in main.cpp to make that easy.
