Apply scripted modifications on an online image<br />
<li>i : image's URL</li><br />
<li>script : an object in json format. It contains the action as key and the parameters as value.<br />
	<ul><br />
		<li>[{"grey":""}] : filter grayscale</li><br />
		<li>[{"pixel":(size,blur])}] : filter pixelate</li><br />
		<li>[{"emboss":""}] : filter emboss</li><br />
		<li>[{"edges":""}] : filter edgedetect</li><br />
		<li>[{"negative":""}] : filter negate</li><br />
		<li>[{"sketch":""}] : filter mean removal</li><br />
		<li>[{"gaussian":""}] : filter gaussian blur</li><br />
		<li>[{"brightness":amount}] : filter brightness</li><br />
		<li>[{"contrast":amount}] : filter contrast</li><br />
		<li>[{"colorize":[FF0000,1-127]}] : filter colorize [color,alpha]</li><br />
		<li>[{"crop":[x,y,w,h]}] : crop image (dimensions in pixels or in %)</li><br />
		<li>[{"resize":[w,h]}] : resize image. if you put -1 instead of one dimension,it resizes with aspect ratio. {"resize":[256,-1]} calculates the new height</li><br />
		<li>[{"rotate":angle}] : rotate image</li><br />
	</ul><br />
	You can chain various actions in one script: [{"resize":[w,h]},{"colorize":["FF0000",1]},{"rotate":90}]<br />
</li><br />
<li>script can also be a json file in scripts/ folder<br />
	<ul><br />
		<li>create a file with your script (ex: {"resize":[w,h],"colorize":["FF0000",1],"rotate":90})</li><br />
		<li>name your file: myscript.json</li><br />
		<li>apply it to a picture with ?i=http://www.server.com/picture.jpg&script=myscript (without the json extension)</li><br />
	</ul><br />
</li><br />
<li>dontsave: avoid saving rendered picture</li><br />
<li>force: force the rendering even if the picture already exists (previous rendering)</li><br />
<li>help: displays this text</li><br />
<li>version: displays this api's version</li><br />
<li><br />
	picslist: returns the rendered images list in json format<br />
	<ul><br />
		<li>&random[=xx]: limit the list getting only xx rendered pictures</li><br />
	</ul><br />
</li><br />
<li>download: downloads the php api file</li><br />
