(3.0.16 - 3.0.18 only, PHP 4 >= 4.0.0)
ImageJPEG -- Output image to browser or file
Description
int imagejpeg (int im [, string filename [, int quality]])
ImageJPEG() creates the JPEG file in filename from the image
im. The im argument is the return from the ImageCreate()
function.
The filename argument is optional, and if left off, the raw image stream will be output
directly. To skip the filename argument in order to provide a quality argument just use an empty
string (''). By sending an image/jpeg content-type using
header(), you can create a PHP script that outputs JPEG images directly.
Note: JPEG support is only available if PHP was compiled against GD-1.8 or later.
quality is optional, and ranges from 0 (worst quality, smaller file) to
100 (best quality, biggest file). The default is the default IJG quality value (about 75).
If you want to output Progressive JPEGs, you need to set interlacing on with
ImageInterlace().

and ImageTypes().
