@m_adam
This is my code:

    def DrawMsg(self, x1, y1, x2, y2, msg):
        """
        This method is called to render the content of the view.
        """

        # Enables double buffering to avoid flickering.
        self.OffScreenOn()

        # Draw the background.
        self.DrawSetPen(c4d.COLOR_BG)
        self.DrawRectangle(x1, y1, x2, y2)
        self.ScrollArea(1, 1, x1, y1, self.GetWidth(), self.GetHeight())

Hello! plugincafe!
I want to save all material's preview image.
And i try to use BaseBitmap.ScaleIt() , but it's not working.
All images remain the before ScaleIt() size，I'm not sure what went wrong.
there are my code:

import c4d


def SetBmpSize(mats,size):
    bmps = []
    for m in mats:
        image = m.GetPreview(0)

        dst_bmp = c4d.bitmaps.BaseBitmap()
        dst_bmp.Init(size, size)
        
        image.ScaleIt(dst_bmp, 256, True, True)

        bmps.append(image)
    return bmps

def main():
    path = "D:\\Program Files\\my folder"
    
    mats = doc.GetMaterials()
    
    bmps = SetBmpSize(mats,32)
    for index,bmp in enumerate(bmps):
        c4d.bitmaps.ShowBitmap(bmp)
        #name = path + "\\" + str(index) + "material preview.tif"
        #bmp.Save(name, c4d.FILTER_TIF, data=None, savebits=c4d.SAVEBIT_0)
    

if __name__=='__main__':
    main()

this is the show in picture viewer after ScaleIt() Image:

All right. Thanks for your reply.
Cheers~

Hi ~
I want to get which port the node's input port connects to. and I try to use gvport.getdestination () in the Python SDK, but I find that the port has to be the output port to return properly, and if the port is the input port, it returns an empty list.
Does anyone know how to return the connected port from the input port?

Cheers~

@zipit
Thank you zipit.
I find your methods convenient, but I still need an iterative approach
Can you give me some simple example?

Cheers
