imageHandler

imageHandler is a PHP (gd) back end class package managing

crop region, resize, adapt size and convert

of bmp, jpg, gif, png, xbmp and xbm image types

with preserved proportions and (for gif/png) transparency. For tiff images with an embedded thumbnail, the thumbnail is returned.

ImageHandler offers also availability "on-the-fly"

using a web (REST GET/PUT, json) service interface.

Anonymous (source and/or output) filenames (without extension) and remote image resources are supported.

The imageHandler output mode is

download

will open a "save file"-box in browser

stream

(default) usable in a "src" statement in a HTML page (resulting in a "thumbnail")

save

saves (resized) image on disk

Output image type for the resized image is (default) png. Non-resizable images types are returned "as is".

The class package includes

the PHP class

the "factory"

the PHP interface script

offering a web service

an PHP "index.php" page,

usable for testing, evaluating and/or image reviewing, including a (separate) editable image crop/resize test schema. The imageHandler class and index page supports PEAR log class or equivalents.

But, despite the most intense review of requirements and conditions in architecture, design and test of imageHandler, the imageHandler's ability to parse and resize an image may still depend on the image origin and the image displayability on browser capability and/or (external) viewers.

Note, imageHandler focus is image cropping/resizing, not image engineering.
