note 33244 added to function.imagecopyresized

Hi, today it took me some hours to figure out this function. This one seems to be _really_ bicubic, because it calculates the rectangles of the src image fitting to one pixel of the dst image and averages them. The Quality is much better than the function with the same name above, but unfortunately its twice or triple as slow. :-( Maybe someone can enhance / tune it. Would be cool. It's still not usable for thumbnail lists. --Daniel function ImageCopyResampleBicubic (&$dst_img, &$src_img, $dst_x, $dst_y, $src_x, $src_y, $dst_w, $dst_h, $src_w, $src_h) { ImagePaletteCopy ($dst_img, $src_img); $rX = $src_w / $dst_w; $rY = $src_h / $dst_h; $w = 0; for ($y = $dst_y; $y < $dst_h; $y++) { $ow = $w; $w = round(($y + 1) * $rY); $t = 0; for ($x = $dst_x; $x < $dst_w; $x++) { $r = $g = $b = 0; $a = 0; $ot = $t; $t = round(($x + 1) * $rX); for ($u = 0; $u < ($w - $ow); $u++) { for ($p = 0; $p < ($t - $ot); $p++) { $c = ImageColorsForIndex ($src_img, ImageColorAt ($src_img, $ot + $p, $ow + $u)); $r += $c['red']; $g += $c['green']; $b += $c['blue']; $a++; } } ImageSetPixel ($dst_img, $x, $y, ImageColorClosest ($dst_img, $r / $a, $g / $a, $b / $a)); } } } ---- Manual Page -- http://www.php.net/manual/en/function.imagecopyresized.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+33244 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+33244&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+33244&report=yes
