[Clipart] Re: SVG support for getID3

[James Heinrich - getID3]

Hi Bryce,

Two things. The simple thing is to figure out the magic bytes that identify 
SVG files and add those into GetFileFormatArray() in getid3.php

The big task is to create module.graphic.svg.php and make it work. I'd 
suggest starting with module.graphic.jpg.php and modify it to suit your 
needs. Stick whatever data you think appropriate wherever it best fits under 
$ThisFileInfo['svg']. What is required is to set the common subkeys of 
$ThisFileInfo['video'] (datatformat, lossless, bits_per_sample, 
pixel_aspect_ratio, resolution_x, resolution_y), as well as 
$ThisFileInfo['fileformat'].

Actually, to simplify your life, I've attached a rough framework for 
module.graphic.svg.php -- please modify as appropriate.
