 pictureType : list
        type of pictures,for example :jpg,png...
 sizeMode : int
     None or 0 for pdf's pagesize is the biggest of all the pictures
     1 for pdf's pagesize is the min of all the pictures
     2 for pdf's pagesize is the given value of width and height

 width : int
     width of the pdf page
 height : int
     height of the pdf page
