When checking out an image using the ArcPad Toolbar, the following error message is displayed:
"The extent of 'the image' is too large to export. Your license does not allow you to encode rasters of this size"
Using the Get Data for ArcPad tool automatically converts an image to Mr.SID format. The Mr.SID format is a Lizard Tech proprietary format which has a 50mb conversion limit in ArcMap.
Using the Get Data for ArcPad tool for ArcPad 6.x was necessary because 6.x only supported SID images. With the release of ArcPad 7.x, other image formats are supported, therefore it is not necessary to convert to a SID image.
