I need to take another look at this. I am now able to reproduce the failure.

The failure does not appear to be in RGB@ nor DRAW_LINE@. Maybe it is in one of the "DIB block" routines when used in a 64 bit application.

I had assumed that you were reporting a regression but this does not now appear to be the case.

In the meantime there is nothing lost by only using the 32 bit version.

Hi Paul

I was about to send you a response, noting that I'd done some more checking, and found that my computer was reporting a memory error when it rebooted, and that perhaps the difference in memory accessed between the 32-bit and 64-bit versions was the problem. Then I noticed that the posts had gone over to a second page, and saw your latest comments.

It's good to know that the problem is real. As you note, I can work around it using the 32 bit version, and I've got to quite like the yellow background for some of my plots.

Merry Christmas

Norm

The fault is in the 64 bit version of RECOVER_DIB_BLOCK@. This has now been fixed for the next release of clearwin64.dll.

Hi Paul

Just to let others (and you) know that replacing

PUT_DIB_BLOCK@ ( flno, ... )

with

nFUNC = Export_Image@ ( flno )

fixes the problem.

I also replaced DRAW_LINE@ with DRAW_LINE_BETWEEN@, and removed

INCLUDE < DBOS.IN >.

Thank you for fixing this for me.

Happy New Year

Norm

To take your comment seriously, I quite like the 64-bit version.

I spend a fair bit of time writing code to process remotely sensed images. I can usually just fit my images in in 32-bit mode, but when there is a bug in my code (and that still seems to happen all too frequently) then it is a pain having to cut down my array sizes so that I can find the bug.

So far, the 64-bit version has alleviated that problem.
