請教前輩:
我裝了Graphicex v9.9 ,design-time時於TImage32元件的bitmap屬性可取入png檔,也看的到圖形,但為何在run-time時,執行Image321.Bitmap.LoadFromFile('c:\k2.png');
時會出現"unknown picture file extension (.png)"之錯誤訊息!請問如何解決?謝謝大家的指導

試試如下的方式:

procedure BitmapFileToPNG(const Source, Dest: String);
var
Bitmap: TBitmap;
PNG := TPNGObject.Create;
{In case something goes wrong, free booth Bitmap and PNG.Assign(Bitmap); //Convert data into PNG.SaveToFile(Dest);
finally
Bitmap.Free;
PNG file to Windows bitmap file
The above inverse. Loads a PNG: TPNGObject;
begin
PNG and Bitmap}
try
PNG); //Convert data into bitmap
Bitmap.SaveToFile(Dest);
finally
PNG.Free;
Bitmap.Free;
end
end;

謝謝版主的回覆!問題已解決
PNG := TPNGObject.Create;
PNG.LoadFromFile('c:\k3.png');
image1.Picture.Assign(PNG );
