POBitmap creation gets all-black when generating lots of them

Body
copied!<p>I'm working with Delphi 7 and I have to generate a lot of bitmaps from a FlashMovie embedded in my Delphi application. Definition of the pictures is 1010x720.</p> <p>When I generate more than 6000 pictures (the number is different everytime), I get an EOutOfResources exception. I've looked around and it seems that it could come from a lack of available handles.</p> <p>Here is the code:</p> <pre><code>var FFlashPlayerControlExport:TFlashPlayerControl; Bmp:TBitmap; pPNG:TPNGObject; begin Bmp := FFlashPlayerControlExport.CreateFrameBitmap; Bmp.Width := StrToInt(aArgs[5]); Bmp.Height := StrToInt(aArgs[6]); pPNG := TPNGObject.Create; pPNG.Assign(Bmp); pPNG.SaveToFile(sFileName); pPNG.Free; DeleteObject(Bmp.Handle); Bmp.Free; end; </code></pre> <p>I have tried CloseHandle(Bmp.Handle) just before Bmp.Free but I'm getting an EExternalException.</p> <p>Thank you all for your help!</p> <hr> <p>UPDATE 06 Dec 2012 :</p> <p>Thanks to Arioch'The's answer, I tried to set the Width and Height of FFlashPlayerControlExport directly instead of using Bmp.Width and Bmp.Height It helped because now I don't get a EOutOfResources exception but the CreateFrameBitmap saves an all-black picture after a while.</p> <p>FlashPlayerControl is still running because I see the picture on the screen.</p> <p>Code update : </p> <pre><code>var FFlashPlayerControlExport:TFlashPlayerControl; Bmp:TBitmap; pPNG:TPNGObject; begin FFlashPlayerControlExport.Width := StrToInt(aArgs[5]); FFlashPlayerControlExport.Height := StrToInt(aArgs[6]); Bmp := FFlashPlayerControlExport.CreateFrameBitmap; pPNG := TPNGObject.Create; pPNG.Assign(Bmp); pPNG.SaveToFile(sFileName); pPNG.Free; Bmp.Free; end; </code></pre> <hr> <p>UPDATE 20 Dec 2012 :</p> <p>After contacting the FlashPlayerControl developper team, I found out that the bitmaps become black when the application reaches 10.000 GDI objects. They provided an effective help with my problem, contacting them is efficient :)</p> <p>I eventually found out that the GDI objects leak comes from another parallel part of my code. This subject is close :)</p>
