Want to make an image tile properly? This is accomplished by swapping all four quadrants of the image. Here is some sample code that uses imagecopy to do it: <?php function backgroundify(&$image) { $ix = imagesx($image); $iy = imagesy($image); $ixhalf = floor($ix / 2); // DON'T USE ON IMAGES WITH ODD SIZES! $iyhalf = floor($iy /2); $panel_temp = ImageCreate ($ix, $iy) or die("Cannot Initialize new GD image stream"); imagecopy($panel_temp, $image, 0,0,0,0,$ix, $iy); imagecopy($image, $panel_temp, 0,0,$ixhalf,$iyhalf, $ix-$ixhalf, $iy-$iyhalf); // move bottom right to top left imagecopy($image, $panel_temp, $ixhalf,$iyhalf, 0,0,$ix-$ixhalf, $iy-$iyhalf); // top left to bottom right imagecopy($image, $panel_temp, $ixhalf, 0,0,$iyhalf,$ix-$ixhalf, $iy-$iyhalf); // bottom left to topo right imagecopy($image, $panel_temp, 0,$iyhalf, $ixhalf,0,$ix-$ixhalf, $iy-$iyhalf); // top left to bottom right } ?> --was-- Want to make an image tile properly?
