Summary Images memory limit?

[zxtunes.com]

I load about 9,000 images, a total volumes of 1.2Gb.
Pictures are small (256x170px)
Windwows x64. Have 8 gigabytes of memory on computer.

Images are loaded and there is no error. However, when the first call StartDrawing (ScreenOutput) I get NULL.
I use full screen app.

I checked this notebook X86 and 1.5 gigabytes of memory.

The result is completely identical. What is surprising.

On the first computer built-in video card.
On a laptop with a discrete 256mb.

In what could be the problem?

PB5.2

Did you make a typo, it should be:

Code: Select all

StartDrawing(ScreenOutput())

This is not funny.

Talk about the work program.

OK. I upload full source package: https://dl.dropboxusercontent.com/u/643 ... Mapper.zip (PB 5.2 need)

This program is needed for live shows, which I do sometimes with friends musicians.

At that time we had a banner 2.5x1.8 meters with a band logo .
In the center was a circle , where the output video. The remaining elements of the picture simply is highlighted in white.

Since it is not possible to install the projector exactly parallel to the screen , we had to make such a program.

The picture is divided into polygons which can be deformed independently . It turned out that they seem to glow .

The problem is that if you load memory images more than 1.2 years we get NULL on first StartDrawing(ScreenOutput()).
And it does not depend on the amount of RAM on your computer.

I believe that it is a bug PureBasic.
I checked on 3 different computers.

You can check this for yourself:
