Description

bool imagejpeg ( resource image [, string filename [, int quality]] )

imagejpeg() creates a JPEG file from the given image.

Parameters

image

An image resource, returned by one of the image creation functions, such as imagecreatetruecolor().

filename

The path to the saved file. If not set or NULL, the raw image stream will be outputed directly.

To skip this argument in order to provide the quality parameter, use NULL.

quality

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).

Return Values

Returns TRUE on success or FALSE on failure.

Notes

Note: JPEG support is only available if PHP was compiled against GD-1.8 or later.

Note: If you want to output Progressive JPEGs, you need to set interlacing on with imageinterlace().
