Hi all!
I currently have PHP Version 4.3.1 and GD Version 2.0.11 up and runing.
When I'm rtying to ImageCreateFromJPEG and creatre a PNG thumbnail of that
image I get result in 256 colors (I guess) - it looks ugly.
When I roll back to GD Version 1.8.4 everything works fine - thumbnails are
TrueColor images.
People say that imagecreatetruecolor() solves the problem. But in my case
ImageCreateTrueColor doesn't work at all - I get just empty squares.
here is the code:
---------------------------------------------------------------------
if (!$bigimage = @ImageCreateFromJPEG($image)) {
$img = ImageCreate(100, 100);
$red = ImageColorAllocate($img, 255, 0, 0);
$yellow = ImageColorAllocate($img, 255, 255, 0);
ImageString($img, 5, 20, 20, "Image", $yellow);
ImageString($img, 5, 20, 40, "not", $yellow);
ImageString($img, 5, 20, 60, "found!", $yellow);
ImagePNG($img);
ImageDestroy($img);
exit();
}
$tnimage = ImageCreate($tnsize, $tnsize);
$darkblue = ImageColorAllocate($tnimage, 0, 0, 127);
ImageColorTransparent($tnimage,$darkblue);
$sz = GetImageSize($image);
$x = $sz[0];
$y = $sz[1];
if ($x>$y) {
$dx = 0;
$w = $tnsize;
$h = ($y / $x) * $tnsize;
$dy = ($tnsize - $h) / 2;
}else{
$dy = 0;
$h = $tnsize;
$w = ($x / $y) * $tnsize;
$dx = ($tnsize - $w) / 2;
}
ImageCopyResized($tnimage, $bigimage, $dx, $dy, 0, 0, $w, $h, $x, $y);
ImagePNG($tnimage);
ImageDestroy($tnimage);
ImageDestroy($bigimage);
----------------------------------------------------------------------------
------
Does anyone know the solution?
Thanks!
