Metafiles consist of both raster and vector data. They are treated as vector files by Didger. That is why in Didger 3, you would import a WMF or EMF file by going to File | Import Vector and not File | Import Bitmap (Didger 3 would actually discard any bitmap information in the metafile).
Didger 4 and Didger 5 will bring in both the vector and raster components of the metafile, but it would also treat it like a vector file and not bring up the Image Registration and Warping dialog. There are a couple things you can do to calibrate it:
- You can "calibrate" a metafile (or any other vector file) after it is imported by going to Map | Coordinate Conversion (Tools | Coordinate Conversion in Didger 4) and selecting the Georeference option.
- If the metafile only consists of images and no vector data (or if you delete the vector data after it is imported), you can select all the images and go to Image | Mosaic to create a single image, then go to Image | Image Registration and Warping to calibrate it. If the metafile comes in as a single image, you can go straight to Image | Image Registration and Warping.
