What is the best way to add a georeferenced raster image



I need to update the active MapView with a new raster image each time there is mouse zoom/scroll input. I have the raw raster image in memory and I know the lat/lon coordinates of the corners of the image.


I have the code working to detect the mouse action and generates the appropriate raster image to fill the display correctly, I just need to work out how to add the raster image quickly. Presumably the best way is to add it by georeference as I know the lat/lon of all four coordinates of the image.


How can I easily inject a raster image using the lat/lon coordiantes of where I want it placed? I know how to do it from a raster image stoared in an MDB file but how can I just add a raster image directly from a memory?


Many thanks for your help.

Hi Adrian


As far as I know, there is no way to display the image directly from memory.


You have to save the image data in a (temporary) file. This file can be displayed with a legend entry. If you don't have a raster feature from a warehouse to use for the recordset of the legend entry, you can do it with a memory recordset (see
