Usage ¶

Go to your tbl_structure.php page (i.e. reached through clicking on the 'Structure' link for a table). There click on "Change" (or change icon) and there you will see three new fields at the end of the line. They are called 'MIME-type', 'Browser transformation' and 'Transformation options'.

• The field 'MIME-type' is a drop-down field. Select the MIME-type that corresponds to the column's contents. Please note that transformations are inactive as long as no MIME-type is selected.
• The field 'Browser transformation' is a drop-down field. You can choose from a hopefully growing amount of pre-defined transformations. See below for information on how to build your own transformation. There are global transformations and mimetype-bound transformations. Global transformations can be used for any mimetype. They will take the mimetype, if necessary, into regard. Mimetype-bound transformations usually only operate on a certain mimetype. There are transformations which operate on the main mimetype (like 'image'), which will most likely take the subtype into regard, and those who only operate on a specific subtype (like 'image/jpeg'). You can use transformations on mimetypes for which the function was not defined for. There is no security check for you selected the right transformation, so take care of what the output will be like.
• The field 'Transformation options' is a free-type textfield. You have to enter transform-function specific options here. Usually the transforms can operate with default options, but it is generally a good idea to look up the overview to see which options are necessary. Much like the ENUM/SET-Fields, you have to split up several options using the format 'a','b','c',…(NOTE THE MISSING BLANKS). This is because internally the options will be parsed as an array, leaving the first value the first element in the array, and so forth. If you want to specify a MIME character set you can define it in the transformation_options. You have to put that outside of the pre- defined options of the specific mime-transform, as the last value of the set. Use the format "'; charset=XXX'". If you use a transform, for which you can specify 2 options and you want to append a character set, enter "'first parameter','second parameter','charset=us-ascii'". You can, however use the defaults for the parameters: "'','','charset =us-ascii'". The default options can be configured using $cfg['DefaultTransformations']
