| 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. |

| 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. |
