+#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.;
