Hi!

I try to create an image from memblock. I currently use a graphics card with 1GB RAM. When my memblock (created with ID 100) is about 4 0000 000 fields (size about 16MB) everything works fine. But when I try to create a memblock of 9 000 000 fields (memblock size about 36MB, value returned with agk::GetMemblockSize(100) ) and then try to use agk::CreateImageFromMemblock(image, 100) I get "Uncaught Exception: Ran out of GPU memory, try using smaller or fewer images". On systems with 2GB of GPU RAM this runs fine. Is it really consuming that much memory? Running Process Explorer shows that my app does not request more than 250MB of GPU RAM. What can i do?

Regards

Artur

Sorry, on 2GB system the same happens -- run out of GPU Memory. If I try to create image from memblock of 16 000 000 elements - 64MB of size - it gets even better, I get "Unhandled Exception: Sprite 0 does not exist". ???

Edit 2: It happens only in Tier2, Tier1 seems to work fine

Edit 2: Sorry for the confusion, I narrowed the problem further and it seems that not the CreateImageFromMemblock causes the problem, but rather SaveImage.

Is it possible to attach a the memblock chunk of your code, so we can test the memory allocation issue

Again, it maybe to do with incorrect memory referencing from AppGameKit to C variables,

Not sure, without looking at how your coding it

Its always wise to deletememblock() once finished with a block - this should release its memory.

Ok Cool - this does work, but probably looking in wrong area for final destination of the saveimage

I have run it in Tier 1 - and PNG file goes here

C : \ Users \ <Username> \ AppData \ Local\ AGKApps \ <Appname> \ media

For Tier 2, they going in here

C : \ Users \ <Username> \ AppData \ Local \ AGKApps \ My Company \ <Appname>


All I did was do a full filename search of the whole C drive to locate the filename.png and they hide in the above too

Not sure why mine states "My Company" unless it was a mishap when I installed VS15

Actually I use my own catalogue structure. Anyway, this does not impact the functionality - values like 3000x3000 and higher stop working. The funny thing is that it sometimes works, sometimes doesn't. Calling GetImageFromMemblock sometimes crashes with 4000x4000, SaveImage ALWAYS crashes. I have to use Tier2 because of some functionality I do not have in Tier1, so I would really appreciate some hints what to do.
