Fix for bug that was causing zones later in the MAPINFOW.PRJ file to be missing from the MapImagery user interface.  This was caused by some strange characters surrounding a new Egyptian entry in the file.  Several other bugs causing leading blanks, and truncated category names were fixed.

This version also contains extensive changes to the handling of registry permission errors, which occur particularly on 64bit Windows 7 when running in 32 bit emulation modes. The software now provides more detailed error messages allowing better diagnosis of registry permission errors.

Fix for some installation issues on recent versions of MapInfo, where the installation program was not detecting the location of MapInfo components.

New code signing certificate for the MapImagery install archive as the previous one had expired.

Some fixes for auto installing the MapImagery toolbar into some recent versions of MapInfo Pro are included in this release.

The new JPEG2000 transparency support, which is a feature only available to licensed users of MapImagery Lite and MapImagery Professional, provides the ability to recognise an alpha layer within a JPEG2000 image, and render this layer as transparent within MapInfo.  This feature is particularly useful for viewing a mosaic of images that overlap, as the alpha layer can be used to mask out those areas of an image that contain bad data.

A new image header file format .MIR (MapImagery Raster) has been created to facilitate support of JPEG2000 transparency and support for rendering of local JPEG2000 files.   This file format replaces the .URL files which were generated by previous releases of MapImagery (Note that URL files will continue to be supported by the raster handler, however .MIR files will be generated by the MapImagery GUI, rather than URL files). 

From the example .MIR file listing shown below you can see that the file contains a URL, and in additional other information specifying how the image should be rendered, in this case "Alpha" options on how the JPEG2000 alpha layer should be rendered.

A new MapImagery options dialog has been created for controlling JPEG2000 alpha transparency.  This dialog controls the transparency behaviour of both the raster handler and the MapImagery GUI.   It is possible to switch off transparency support temporarily via this dialog.   It is also possible to change the colour, used to communicate transparency between the MapImagery raster handler and MapInfo.   Usually this is not necessary, as the default is fine for the vast majority of images.

The MapImagery user interface has been changed to reflect the support for JP2000 files.  In places where the ECW extension appeared in the past, now both the ECW and JP2 extension appear.   For example the main menu entry that used to read 'Open ECW Image...' now reads 'Open ECW or JP2 Image...'.

A section has been added to the online help on JPEG2000 alpha transparency support.  This section can be found here:
