imagejpeg
(PHP 3>= 3.0.16, PHP 4 , PHP 5) imagejpeg -- Output image to browser or file
Descriptionbool imagejpeg ( resource image [, string filename [, int quality]] ) imagejpeg() creates the
JPEG file in filename from the image
image. The image 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.
Замечание: 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().
