In ZWCAD2008i version, we improve the Insert function to help engineers, especially topographical engineers, to manage TIF / TIFF images in a convenient way. It means TIF / TIFF images can be inserted with TFW coordinate file. Following is an example to describe the feature.
Suppose that there is a new city to be built, firstly the city territory, appearing as a DWG file, shall be divided using topographical coordinates as some small area, such as using rectangles to mark them. And for each resulting rectangle, there is an image, TIF or TIFF format, taken by plane to stand for. Furthermore, each image stores the exact coordinate data in the DWG file, and all of the data info is saved in a TFW file. Now while inserting the TIF or TIFF images into the DWG file, the TFW coordinate file can be inserted as well in the dialog box to let the different images match different rectangles.
