GDI+ 記憶體不足

using (Graphics g = Graphics.FromImage(bmp))<br /> {<br /> //Graphics g = Graphics.FromImage(bmp);<br /> g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;<br /> g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;<br /> g.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality;<br /> g.DrawImage(image, 0, 0, image.Width, image.Height);<br /> //}<br /> //下面的浮水印操作，就直接對 bmp 進行了<br /> //......<br /> addWatermarkText(g, addText, "WM_TOP_LEFT", 130, 200);</p><p> resultImage.Image = bmp;<br /> g.Dispose();<br /> MessageBox.Show("浮水印添加成功！");<br /> }<br />

這種使用using的方式，在使用完成之後，自動回收，釋放資源

 

如果手動的用g.dispose()；可能會造成釋放不完全，出現記憶體不足的錯誤
