ColorProfileConvert.__init__()

ColorProfileConvert.PrepareTransform()
Prepares the color conversion i.e. checks if a conversion is needed.

ColorProfileConvert.Convert()

Converts the color profiles of the pixel data.

Methods Documentation

ColorProfileConvert.__init__(self)
ColorProfileConvert.PrepareTransform(self, srccolormode, srcprofile, dstcolormode, dstprofile, bgr)
Prepares the color conversion i.e. checks if a conversion is needed.
A conversion is only necessary if True is returned. Two identical color spaces will return False.

  • dstprofile (c4d.bitmaps.ColorProfile) – The destination color profile.

  • bgr (bool) – True to swap the RGB channels. Only necessary when working directly with Windows bitmaps.

Return type

bool

Returns

True a conversion is necessary, otherwise False.

ColorProfileConvert.Convert(self, src, dst, cnt, skipInputComponents, skipOutputComponents)

Converts the color profiles of the pixel data.

Parameters

  • src (bytes) – The source pixel buffer.

  • dst (bytes) – The destination pixel buffer.

  • cnt (int) – The number of pixels to convert.

  • skipInputComponents (bool) –

    The number of bytes to skip in the source buffer after each converted pixel. For instance a RGB pixel contains 3 bytes.
    After conversion the number of skipInputComponents bytes is added to the source pointer.

  • skipOutputComponents (bool) –

    The number of bytes to skip in the destination buffer after each converted pixel. For instance a RGB pixel contains 3 bytes.
    After conversion the number of SkipOutputComponents bytes is added to the destination pointer.
