---------
When I load a texture direct in a material channel, c4d show the resolution info.
How can I get this information?

And what if I have textures in a layer shader.
How to get the resolution for all images in the layer shader?

I found an old post from Matthias.
Is this the way to go?

Unfortunatly the resolution or the link to the bitmap is not stored in a container. You have to check the bitmap manually, going by the path provided.

cheers,

I think he meant that you have to get the information from the image file manually.
Like this:

    Filename fn = GeGetC4DPath(C4D_PATH_DESKTOP) + "myimage.jpg";  
  
  AutoAlloc<BaseBitmap> bmp;  
  if (IMAGERESULT_OK != bmp->Init(fn)) return FALSE;  
  
  LONG bw = bmp->GetBw();      //The image width  
  LONG bh = bmp->GetBh();      //The image height  
  GePrint(LongToString(bw));  
  GePrint(LongToString(bh));  
  
  
  MultipassBitmap *mbmp = NULL;  
  mbmp = MultipassBitmap::Alloc(bw, bh, COLORMODE_RGBf);  
  if (!mbmp) return FALSE;  
  
  GeData d = mbmp->GetParameter(MPBTYPE_DPI);  //Gets the dpi info  
  LONG dpi = d.GetLong();  
  GePrint(LongToString(dpi));  
  
  MultipassBitmap::Free(mbmp);

Yes, that is what I thought.
I use GetColorMode.

	orgImage->Init(fname, -1, nullptr);
	Int32 colorMode = orgImage->GetColorMode();	//The image colormode
	Int32 bw = orgImage->GetBw();				//The image width
    Int32 bh = orgImage->GetBh();				//The image height

Here also a translation from the Int32 colormode to a String with the colormode description
Perhaps someone might find it useful (it saves typing in).

String modeToString(Int32 colorMode)
{
	switch (colorMode)
	{
