I'm trying to resize GIF images and up with very large files
For example:
Original width = 720
New width = 980
Original height = 1008
New height = 1274
Original filesize = 80kb
After resizing = 235kb
Based on the area increase; I'd expect the file size to about double, not be
4x as large.
$src_img = imagecreatefromgif($filename);
$dest_img = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($dest_img, $src_img, 0, 0, 0, 0, $new_width, $new_height,
$org_width, $org_height);
imagegif($dest_img, $filename);
I tried using imagetruecolortopalette() and it helped a little; but screwed
up the image quality.
Can anyone explain or have a solution?
What's the image? If it's photo-like, save it as a PNG or JPEG and you'll
get much smaller files. GIF's don't do very well with some images as it
can't encode them very efficiently.
I don't remember which way it goes, but a 1x500 gif of a solid color will
be much much much larger than a 500x1 gif of a solid color. The latter it
can compress by sayign something like "x color for the next 500 columns on
this row".
If it were me, I'd try jpeg/png first.
