#X text 50 12 Synopsis: [pix_alpha];
#X text 29 56 Description: set the alpha values of an RGBA-pix;
#X text 21 229 It defaults to highThresh = 0 0 0 \, lowThresh = 0 0
0 \, passVal = 0 \, and otherVal = 1 This makes any black pixels totally
transparent.;
#X text 22 170 pix_alpha compares at the color component level \, so
if you wanted pixels with any red and no green or blue in them to be
set to the passVal \, make highThresh = 1 0 0 and lowThresh = 0 0 0
;
#X text 21 74 pix_alpha sets the alpha values of a pix based on a simple
thresholding. If a pixel value is between the high and low threshold
RGB values \, then the alpha component of the pixel is set to the pass
value. If the pixel value is below the low threshold or above the high
threshold \, then the pixel alpha is set to the other value.;
