Hello,

has anyone made experiences with Bodypaint Bitmaps.
If I check the dirty state of a bitmap like:

  
  Tex = bodypaint.PaintTexture.GetSelectedTexture()  
  actlay= Tex.GetActive()  
  if actlay.IsInstanceOf(c4d.OBJECT_PAINTLAYERBMP) == True:  
        
      bmp = actlay.ToPaintLayerBmp()  
      bmp.GetDirty()

I´ll get this error message:

SystemError: /perforce_buildsystem_osx/c4d_mx_buildsystem_osx/release/16.0/modules/python/source/i_getargs.cpp:1616: bad argument to internal function

I´m not allowed to set a zero flag as it is suggested in the docs:
``PaintBitmap.GetDirty( _flags_ )[URL-REMOVED]

Thanks in advance
Martin

You've created a paint layer bitmap. Which doesn't have a GetDirty() method.
You'll need to convert it to a BaseBitmap() type using GetPixelCnt() to loop through it and copy the color values to a new BaseBitmap with SetPixelCnt().

Then you should be able to use GetDirty() on it.

Hello Scott,

yes thanks! I see.
But it doesn´t make sense to me as im able to use the other members of the class with
bmp = actlay.ToPaintLayerBmp()

I want to avoid recalculating the Bitmaps on every event message in my plugin.
I copied the BP layer structure to a treeviewcustomgui and an userarea in my dialogplugin.
That´s why I was searching for a fast indicator that the user changed something at the PaintBitmap
and I thought GetDirty should be good enough.
Do you have an idea to solve this in fast manner.

Thanks in advance
Martin

No idea.
I've never tried using the layer images in other GUI's.

Sorry.

ok.
By the way the treeviewcustom gui on your website was a good resource to begin with.Thanks

my dirty status is always 1, as expected.
Because I have to initialise the bitmap in the first place or load it from a path to use GetPixelCnt()/SetPixelCnt()

So is my assuption right that the dirty status of a bitmap only reflects the count of how often a bitmap was saved with c4d and therefore it is not possible to detect if a bitmap has changed without saving it to disc?

Could someone please throw light on this issue?
Thanks in advance

Hello,

the dirty count is increased every time a part of the bitmap is changed. Unfortunately there is a bug in PaintBitmap.GetDirty(). A bug report was filed.

Best wishes,
