Note: Even when the position is in latitude and longitude, you should
also check the datum. Usually this will be WGS1984, but it might be different
and could cause an error in the position. Also, if the value of “Pixels/Inch” for
the image is set to 100, then the image will look wrong, both in the preview
and when it’s imported. The only cure for this problem is to import the image
into another application (PaintShop, Paint, etc.) and re-save it at the smaller
or larger size desired.
World files, for example, contain the kind of parameters listed in Table 1.
(See ‘A Look at Geo-Referencing in a World File’ for a full explanation of
the contents of that kind of file.) Or perhaps you have a text file that has the
information DelphMap needs. An example of the latter is shown in
Figure 15.

Click OK to import the background layer image. 4.
The file is imported as a background layer into your imagery. Also, the
file name appears the Project Files Window under the Background
Layer label. Figure 16, Figure 17 and Figure 18 show examples of
this.
