Hi!
I am using Delphi 11 Alexandria.
When calling ievision findContours method inside a thread, I am getting the following message:
Project XXXXXXXXX.exe raised exception class $C0000005 with message 'c0000005 ACCESS_VIOLATION'.
The call stack shows this:
I have just copied the following code from an initial prototype development where works with no issues:
LFindContourImage := IEVisionLib.createImage(LIntermediateImage.GetIEVisionImage.getWidth, LIntermediateImage.GetIEVisionImage.getHeight, ievUINT8, 1);
LFindContourImage.operatorASSIGN(LIntermediateImage);
LContourRef := LFindContourImage.FindContours(IevEXTERNAL,ievCHAIN_APPROX_SIMPLE,IEVisionPoint(0,0));
Have you had any problem like this before?
By the way, in the same thread I am using other methods like erode or threshold with no AV.
Thanks,
GEVI
