Input params for convert [cleanup]

• source - depending on action: file: a multi-part file uploaded, post: a post var containg content, url: the url to use
• save_as - filename returned in the headers, defaults to the basename of the original input. (required for convert/post)
• max_jpeg_size - the max size width or height of jpeg desired, aspect ratio will be kept

[optional]

• target_format - [default: jpeg] only jpeg supported.
• eps_width - [default: calculated] a hint to the system about the width of the eps
• eps_height - [default: calculated] a hint to the system about the height of the eps

note: eps_width and $eps_height are helpful so the convert script does not need to figure out the size.
