Resolve poor performance when using large JPEG Aerial images in MapInfo Professional v16


When using Mapinfo™ Pro v16 and .JPEG Aerial photography, you notice a decrease in performance in the application during general use.


At present, there is no support for .JPEG file types when using the Mi Raster handler in MapInfo Pro™ v16. This is to say that there are no pyramid index files (.PPRC) created when opening a .JPEG image in the application.

As a result of this, larger .JPEG files (>50mb) may perform sluggishly when panning and zooming around the map.


UPDATED: March 28, 2018
.TIFF file types are supported in MapInfo Pro™ v16 by MiRaster and so performance should be significantly improved when using this file format. In addition, you will be able to make use of the "Merge" function to combine these images into .MRR format, improving the performance further.

.JPEG file type support in MiRaster is scheduled (subject to change) for a future release of MapInfo Pro™.
