There may be numerous situations when the order of conversion is of importance. Although it may seem first that if images that need to be converted can be “all put in one basket”, exceptions are quite often. For example, original image files may be all in the same folder, but refer to different dates; or images of larger size should be resized first. This means that when setting conversion parameters one may prefer to specify a certain order of conversion and start with files of specific names, or file type, properties, or the image size. Setting these parameters can be performed via the command-line.
