NAME

perl_fu_pixelgen - Generate the pixels of an image by expressions (in PDL)

SYNOPSIS

image = perl_fu_pixelgen (run_mode,width,height,type,expression)

DESCRIPTION

DESCRIPTION Not yet written yet, sorry... $p The source pixels (1..4 bytes per pixel, depending on format). Use like this: $p*3.5 # the return value is the result $P The source pixels without alpha. Use it like this: $P *= 0.5; $p # modify $P inplace, return also modified $p as result $x A two-dimensional vector containing the x-coordinates of each point in the current tile: $x = (zeroes(long,$w)->xvals + $destination->x)->dummy(1,$h)->sever; $y A two-dimensional vector containing the y-coordinates of each point in the current tile: $y = (zeroes(long,$h)->xvals + $destination->y)->dummy(0,$w)->sever; $bpp The bytes per pixel value of the destination area.
