tgetp

Syntax

int tgetp(int x, int y)

Arguments

x, y
Image coordinates

Return

Returns the pixel value at the specified image coordinates

Description

This function lets you read a whole pixel from the first tile buffer. Unlike tget the returned value includes the values of all color channels (including the transparency channel if one is available) of the pixel. Using tgetp instead of tget takes only approximately half as much time. To decode the individual color values from the returned pixel value you have to use the Rval, Gval, Bval and Aval functions. Currently only works with 8 bit images.
