有助于解决“内存不足”异常调用DrawImage的时候 [英] Help to resolve 'Out of memory' exception when calling DrawImage

问题描述

一成左右的使用者在使用我们的应用程序出现突然死机。该日志显示以下异常，我已经看到了迄今为​​止唯一的共同点是，它们都具有XP SP3。

在此先感谢

解决方案

我敢肯定，你想通了这一点了，但如果你没有我们打了同样的问题。这是在GDI +中的错误，这可以作为一种解决方法。不幸的是我不知道的为什么，但这些各种各样的问题，我倾向于更关心，它的固定少，为什么它的固定。 ;）

 图像= image.GetThumbnailImage（image.Width，image.Height，空，IntPtr.Zero）;
 

显然，这一呼吁调整的PixelFormat并把图像的格式的DrawImage的图像列表的使用可以处理。

About one percent of our users experience sudden crash while using our application. The logs show below exception, the only thing in common that I've seen so far is that, they all have XP SP3.

Thanks in advance

Out of memory.

解决方案

I'm sure you've figured this out by now, but in case you haven't we hit the same issue. It's a bug in GDI+ and this works as a workaround. Unfortunately I don't know why but with these sorts of issues I tend to care more that it's fixed and less why it's fixed. ;)

image = image.GetThumbnailImage(image.Width, image.Height, null, IntPtr.Zero);

Apparently that call adjusts the PixelFormat and puts the image in a format that the imagelist's usage of DrawImage can handle.
