Description
This script allows to display images that are loaded in memory without the need of
temporary files. There are 2 main usages:
- When an image is retrieved from a database
- When an image is created with GD
MemImage(string data, float x, float y [, float w [, float h, [array link]]])
$data holds the image in memory. It must be in PNG format.
GDImage(resource im, float x, float y [, float w [, float h, [array link]]])
$im is a GD identifier. If you use JpGraph, you can retrieve it via a call to
$graph->Stroke(_IMG_HANDLER) (from version 1.10.1).
Moreover, this script allows to call the standard Image() method with a URL of the form:
var://variable
where variable is a global variable holding an image (PNG or JPEG).
This feature requires PHP>=4.3.2 and FPDF>=1.52.
