AcDbRasterImage and lazzing loading...

[Anonymous]

Hi,
I am having problems using AcDbRasterImage.
The user select images to load.
So I have a loop where an image is loaded at each step.
But AutoCAD don´t make any memory verification, so Autocad CRASH when
memory available finish.
I tried to check my memory available inside my loop and skip the loop when
memory finish, but AcDbRasterImageDef::load is a lazzing and images is
loaded when my command finish.

Anyone have any solution???

Thanks,
Aragao

Hi,

My code is something like that:

size=2>::attachImage(const std::vector<CSgString>&
