The problem I have is that half the functions do not return a result.
Can anyone tell me why?
example code that does not work:
Code: Select all
<?php
$image="orig_image.jpg";
$output = "output_image.png";
exec("convert -size 500x500 xc: -channel G \
-fx 'sc=.15; (i/w-.5)/(1+sc*cos(j*pi*2/h)-sc)+.5' \
-separate map_hourglass.png
convert $image -matte -bordercolor none -border 1x0 map_hourglass.png \
-channel RGBA -fx 'p{ v.p{i*v.w/w,j*v.h/h}.g*w, j}' \
-shave 1x0 $output ");
echo "<br><img src=\"". $output ."\"><br>";
?>
