Large Bitmap on Delphi

Question

I want to create large Bitmap with code ``` LargeBmp := TBitmap.Create; try LargeBmp.Width := 1000; // fine LargeBmp.Height := 15000; // XP - EOutOfResources, Not enough memory, Win 7 - works fine ... finally FreeAndNil(LargeBmp); end; ``` This code raises an `EOutOfResources` exception with message "Not enough memory" on Windows XP but works fine in Windows 7. What is wrong? Why Not enough memory? It's only 60 MB.

Accepted Answer

Set the pixel format like this:

```
LargeBmp.PixelFormat := pf24Bit;
```

I had the same problem several times and that always solved it.
