copyDataToChannels()

uint32_t KisTIFFReaderFromPalette::copyDataToChannels ( quint32 x, quint32 y, quint32 dataWidth, QSharedPointer< KisBufferStreamBase > tiffstream )

inlineoverridevirtual

This function copy data from the tiff stream to the paint device starting at the given position.

Parameters

x	horizontal start position
y	vertical start position
dataWidth	width of the data to copy
tiffstream	source of data

Returns

the number of line which were copied

Implements KisTIFFReaderBase.
