10 | Uses the GD, ImageMagic or NetPBM to manipulate |
---|
11 | images online. ImageMagic is preferred as it provides |
---|
12 | the best rotation algorithm. Below is a brief comparsion |
---|
13 | of the image manipulation packages. Personal preference |
---|
14 | is ImageMagick. |

17 | ------------------------------------------------ |
---|
18 | GIF NO(1) YES YES |
---|
19 | JPEG YES(2) YES YES |
---|
20 | PNG YES YES YES |
---|
21 | Cropping Good Good Good |
---|
22 | Scaling Fair Good Very Good |
---|
23 | Rotation Poor Fair Very Good |
---|
24 | Flip Good Poor Good |
---|
25 | |
---|
26 | |
---|
27 | (1) GIF is support in old GD say version 1.61 and below |
---|
28 | (2) Full colour JPEG is not supported in GD versions |
---|
29 | less than 2.01 with PHP. |
