Image File Format


The image file must be a standard text document, with tabs as separator. An image fine consists of five entries. The first one is a pointer to an existing .jpg file, the last four entries give the coordinates of the upper left and lower right points (normally 0,0,imagewidth,imageheight are good values). These values are essential, if the coordinate variables in the dataset are coordinates that do not match with the pixel size of the image.

The following file is CityImage.txt from the "Augsburg Traffic Data".
