[18:03:35] <Harri1>	 what exactly does doTransform method do?
[18:04:56] <Harri1>	 if i define define the method in my class as function doTransform( $image, $dstPath, $dstUrl, $params, $flags = 0){, what parameters are passed to that function or do i have to parameterize everything
[18:05:39] <Harri1>	 i would assume, i need to redefine $image, but dsturl and dstpath should be predefined
[18:36:21] <Platonides>	 Harri1: did you look at the original one?
[18:44:27] <brion>	 Harri1: start with the docs on the base method: https://doc.wikimedia.org/mediawiki-core/master/php/classMediaHandler.html#a32a05d4674c0dbda7cd145e9fab42b3d
[18:44:49] <brion>	 you may wish to also look at the implementations on the various *Handler classes that implement more or less concrete types
[18:44:57] <brion>	 $image is an input parameter, you don't change it :)
[18:45:08] <brion>	 you return a MediaTransformOutput which contains various info
[18:45:26] <brion>	 about your actual output image/data/html
[18:51:15] <Harri1>	 yes i looked at djvuhandler
[18:51:35] <Harri1>	 from that i found that the method should return new ThumbNailImage
[18:52:16] <Harri1>	 but that's what my problem is, the $image parameter should be null
[18:52:35] <brion>	 i don't understand Harri1 
[18:52:41] <brion>	 the $image parameter should NEVER be null?
[18:52:47] <brion>	 it refers to the source file you're transforming
[18:53:11] <Harri1>	 aah, so image is just a variable name
[18:53:14] <brion>	 yes?
[18:53:19] <Harri1>	 gotcha
[18:53:32] <Harri1>	 that led me off the tracks
[18:53:45] <brion>	 historically the file uploads system was originally called "image" not "file" so you'll find a mix of terminology
[18:53:59] <brion>	 for instance the metadata is still in a table called 'image' etc :)
[20:27:20] <Harri1>	 hmm
[20:28:25] <Harri1>	 so, from what i understand, the dotransform method is a proxy method for changing the parameters like width and height to send to thumbnailImage
[20:39:21] <Harri1>	 just wondering how would i get the snapshot image parameters i create with js back to php
[20:48:55] <Platonides>	 ajax?
[20:49:14] <Platonides>	 a commons way is to use thumb.php
[20:50:22] <Platonides>	 *common
[21:27:30] <Harri1>	 what do you mean use thumb.php
[21:27:38] <Harri1>	 sorry, i dont follow yet
