MapInfo Pro

I'm trying to open 8 bit GeoTIFF images in MapInfo Pro v2019. It seems to automatically be making white pixels transparent?

I've tried setting no transparent colour (or setting a different colour) under Adjust Image Styles, but the white pixels are always transparent in the map.

I've tried searching for a solution but didn't find any. Closest I got was some discussion about alpha channels and being able to disable this under the Raster options, however it appears that Raster options are now not available in the standard licence anyway?

Thanks,

Hi Timothy,

Can you share a GeoTiff raster that you are using?

Thanks,
Andrei

Hi Tim,

Great to hear from you as well!

Can you try to disable MiRaster handlers in Raster Preferences dialog? You will need to do it for both Native and GDAL drivers (see attached images).
That would force Pro to use older raster handlers.

Regards,
Andrei

Hi Andrei,

Am I supposed to see Raster Preferences under the Pro tab? Because I can't....

I also can't see a Raster tab in the ribbon. Does this mean maybe I missed something with the installation?

Hi Timothy,

You don't have Mapinfo Pro Raster Add-in running that's the reason why Raster preferences are not getting displayed.

You can go to Home->Tool Extension->Registered and in the tools manager window, check if Mapinfo Pro Raster Add-in is available. If it's available, click on the "Load Tool" button.

Once the Add-in is loaded, you will see the option that Andrei mentioned.

Thanks
