Tom - can you provide a bit more information?
1) are you outputting TIFF format, and have you tried other formats?
2) are you using any compression?
3) have you tried reading your output images in software other than MapInfo?
4) are the images 8 bit, 16? single, multi band? integer or float?
5) can you upload a small sample for us to examine?
I have tried multiple formats and compressions with the same results.
I have tried opening or viewing with graphics programs like Photoshop and Irfanview with the same results.
I have attached sample.zip containing a rectified image from 10.1
The image is fairly low res earth imagery, is visible with ArcMAP, but black with Photoshop.
9.3 or 10.0 did not give me this type of grief.
Thank you in advance
I was just helping a client with almost the same issue (8-bit RGB TIFF, saves as rectified black TIFF) and found the same fix, but I was setting 255 as the nodata value. You actually can still use this file, but you have to set RGB stretch to not-None in ArcMap and this doesn't help you at all outside ArcMap.
I didn't get any joy out of changing the environment settings, mostly because I believe they only apply to geoprocessing tools.
My Google-Fu failed. Does anyone know of a way to set the default nodata value in the Georeferencing - Rectify - Save As dialog so that you don't have to reset it for every single rectification?
