Hi Jocelyn! First of all, let me remind you of the hardcoded limitation MapInfo has on large outputs. On Friday, August 13, 2004, Cinda Graubard from GeoMax wrote to this list:
MapInfo tech support has confirmed what a client recently stated: MapInfo has a hard wired printing limitation of 28,000 pixels per any row or column. Tech support told me that MapInfo imposes this limitation in order to keep the software compatible with Microsoft's Windows 98 or lower operating systems. That's one factor to bear in mind. But the pixel size you needed seems to fall short of that limit by far. The image size you indicate may compressed fit into a jpg file of 20 MB but may during creation occupy 500 MB or more of RAM memory. Even if you have 1 GB of RAM, the available part of that during operation may be much smaller. So my guess is that RAM memory is the limiting factor here, since you are able to create a file with a lower resolution. In my experience, MapInfo does not like to diskswap memory and aborts the process when it runs out of memory. I also sometimes wonder if there is some hardcoded RAM limitation in MapInfo as well, for reasons similar to the above. Increasing RAM may be costly, and may not even help, so my suggestion is that you look into the printing process. Do you really need to print the full 914x1600 image at 300 dpi? Could you perhaps create the image with 150-200 dpi and then resample it in Photoshop? My guess is that the difference will be hard to tell, and lost in the fuzzyness that the jpeg compression will create anyway.

I am attempting to create a 300dpi jpeg file. Window size is 914mm/1600mm ; 10794/18897 pixels. I get an error message: 0# file not registered for access. I have successfully created a 150 dpi file, whoever a higher resolution is required jpeg for use in a photo package. I have 1GB ram. I look forward to any help.
