`c4d.bitmaps.BaseBitmap` ¶

The bitmap class can be used to load, read, draw and save bitmap pictures of various formats. Be sure to call BaseBitmap.Init() before you attempt to use a newly allocated bitmap.

Note

Bitmaps are organized so that x = y = 0 is the top left corner.

Note

Though the bitmap class can work with other bit depths than 24 and 32, please note that only these function support other bit depths: BaseBitmap.GetBw() , BaseBitmap.GetBh() , BaseBitmap.GetBt() , BaseBitmap.GetBpz() , BaseBitmap.Init() , BaseBitmap.GetPixelCnt() , BaseBitmap.SetPixelCnt() , BaseBitmap.SetCMAP() , BaseBitmap.AddChannel() , BaseBitmap.RemoveChannel() , BaseBitmap.GetAlphaPixel() , BaseBitmap.SetAlphaPixel() , BaseBitmap.GetChannelCount() , BaseBitmap.GetChannelNum() (to use higher bit depths or multiple channels, see MultipassBitmap ).

Members ¶

BaseBitmap. __init__ ( ) ¶

Return type:	`BaseBitmap`
Returns:	The new bitmap.

BaseBitmap. __getitem__ ( key ) ¶

This is similar to GetPixel() . An example:

r, g, b = bmp[5, 5] #returns the color of a pixel at position x(5), y(5)

Raises:	IndexError – If the pixel position is out of the bitmap boundaries. See `GetSize()` , `GetBw()` and `GetBh()` .
Parameters:	key ( int ) – The pixel position.
Return type:	tuple(int, int, int)
Returns:	The color of a pixel. Range between 0-255 .

BaseBitmap. __setitem__ ( key , value ) ¶

This is similar to GetPixel() . An example:

bmp[5, 5] = (50, 255, 50) #returns the color of a pixel at position x(5), y(5)

Note

The Vector objects does not support item deletion. For instance by calling del(bmp[5,5]) .

Raises:	IndexError – If the pixel position is out of the bitmap boundaries. See `GetSize()` , `GetBw()` and `GetBh()` .
Parameters:	key ( int ) – The pixel position. value ( tuple ( int , int , int ) ) – The color of the pixel. Range between 0-255 .

BaseBitmap. __eq__ ( self , other ) ¶

BaseBitmap. __ne__ ( self , other ) ¶

Check if two references point to the same bitmap.

Note

Does not compare if two references are equal.

BaseBitmap. SetPixel ( x , y , r , g , b ) ¶

Sets the pixel at (x, y) to the color specified by (r,g,b) (0 <= r/g/b <= 255) . Similar to the __setitem__() .

Note

Currently this method does no range check of x and y . This might be added in the future. Please do the check on your own.

Parameters:	x ( int ) – The X coordinate. y ( int ) – The Y coordinate. r ( int ) – The red component. g ( int ) – The green component. b ( int ) – The blue component.
Return type:	bool

conversion ( c4d.bitmaps.ColorProfileConvert ) –
New in version R17.032.
This should be normally set to None . Pass a color profile only if a conversion is wanted before retrieving the pixel data. This only works if either the bitmap is 32-bit per component (so no 8/16-bit images) or the dstmode is 32-bit per component. The conversion is done before color reduction (e.g. if dstmode is 16-bit the profile is first applied and then the data resampled to 16-bit).

Return type:

bool

Returns:

True if successful, otherwise False .

BaseBitmap. SetPixelCnt ( x , y , cnt , buffer , inc , srcmode , flags ) ¶

Sets cnt pixels at ( x , y ) in the bitmap from buffer with mode srcmode , incrementing inc bytes for each pixel. The following example shows you how to read/write from/into an image:
