AV when assigning big images to walls

Markus · Post by **Markus** » Wed Jan 21, 2009 9:44 am

Hi,

when I assign a large image (1280 x 1024) to a wall I get an AV. The debugger indicates that the problem is in TeCanvas, Line 3495.

Steps to reproduce:

Put a Tchart on a Form and a TImage. Load an image into the Timage and assign it to one of the walls:

Chart1.BottomWall.Picture.Assign(Image1.Picture);

Btw IIRC the same happens for the ImageTool.

TChart Source version 8.04, Delphi 2009 with all updates

Best regards,

Markus

Hi Markus,

Thanks for reporting. I have been able to reproduce the problem here and added it (TV52013764) to the defect list to be fixed. It seems it's a D2009 specific bug. It works in Delphi 7, for example.

Wow, I am impressed - that was a quick answer. Thanks

Hi Markus,

I found that assigning the image directly to the wall using the chart editor works fine too.

Hi Narcis,

how do you mean assigning it via the chart editor?
Do you mean assigning an image to the fill pattern?
If that is the case, this is not the same as assigning to the picture property.

Btw, I think that the Picture property of the walls never made it into the chart editor.

Hi Markus,

Yes, exactly, assigning the image via the pattern editor.

As I said in my last post, the pattern image is not the same as the picture for a wall. I think you should also add this new picture property to the chart editor, for the sake of completness.

Hi Markus,

Ok, I've added this to the list too.
