Re: PEMPro on ASI6200 & QHY600


Ray Gralak
 

Bill,

I can't be sure because I don't have one of those cameras but this issue might not affect PEC acquisition since only one full frame
image ever needs to be in memory at a time. From what you told me the problem with allocating the Bitmaps doesn't occur until
PEMPro's polar alignment steps that requires three images to be in memory simultaneously. Each image can use 60M * 4 bytes (240MB),
resulting in 720MB of memory out of the totally available GDI+ memory (1GB). Successful allocation of those images also assumes that
the 1GB is not so fragmented that the large chunks can be allocated. If the graphics memory cannot be allocated you will get the
error message you have reported.

Is there a possible solution? Maybe, but it may not be a quick and easy fix. It may also require purchasing or borrowing a $5K
camera to test with. Plus, privately and publicly you seem to be demanding that I drop everything I am doing to perform an immediate
fix for a camera that just came out that is causing an unexpected problem for which there may not be an easy fix.

I told you privately I would look into this, but it is not likely going to be done soon and I can't promise you a solution. If that
is not acceptable to you then I can refund the money you paid for PEMPro even though you've been using it for years.

Best regards,

Thanks for the history lesson. Fix the software and stop blaming Microsoft.

Bitmaps, the class in .Net Framework, is not the same as the low-level bitmaps in windows that I think you are
talking about.

And it's not 30 years old... only about 20 years old, which is why the limit was only 1GB.

Back then 1GB was an impossible amount of graphics memory for a desktop computer. Not at all today! :-)

The problem IS NOT on the .Net Framework, Ray. The camera works perfectly fine with other software that uses
the same framework.

Bitmaps... which PEMPro uses, should be suspect. Why the hell does PEMPro rely on bitmap tech? Thats like
30
years old man!

Bill,

The problem is that the .NET framework cannot allocate enough memory with a camera with that many pixels.

It could be fixed by Microsoft increasing the .NET Framework GDI+ memory limit above 1GB (not likely).

Or, you could use a cheap webcam instead of a 60 megapixel camera.

Is non-functional. The frames even binned 4x4 do not work.

The software is broken and a LOT of people depend on this to work. We need immediate fixes!
