libpng警告:使用libpng-1.2.26构建但使用1.5.2运行的应用程序 [英] libpng warning: Application built with libpng-1.2.26 but running with 1.5.2

问题描述

我在Mac上尝试R生成png图像时遇到问题.

I have a problem on my mac when trying in R to produce png images.

我收到以下警告:

libpng警告:使用libpng-1.2.26构建但以1.5.2运行的应用程序

我正在使用R-studio GUI运行R 2.14版本.

I am running the R 2.14 version using the R-studio GUI.

我不确定libpng问题.当我定位libpng-config时，我遇到了一些问题，有些是libong-config12，有些是libpng-config14，有些没有讨厌的数字:

I am not excatly sure about the libpng problem. When I am doing locate libpng-config I'm getting several hits, some with libong-config12, some with libpng-config14, some without nay numbers:

ayeroslaviz:〜ayeroslaviz $找到libpng-config
/Applications/XAMPP/xamppfiles/bin/libpng-config
/Library/Frameworks/GTK+.framework/Versions/2.18.X11/Resources/bin/libpng-config
/opt/local/bin/libpng-config
/usr/X11/bin/libpng-config
/usr/local/bin/libpng-config

当执行哪个 libpng-config 时，我得到:/usr/local/bin/libpng-config

When doing which libpng-config I'm getting: /usr/local/bin/libpng-config

是否可以卸载旧版本的libpng或将路径更新为正确的版本.不幸的是，我什至不确定该警告的来源，因此希望在此提供所有必要的信息.

Is there a way to uninstall older versions of libpng or update the paths to the right version. Unfortunately I am not even sure, what thesource of this warning, so I hope I gave here all the needed information.

如果有人给我提示如何解决此问题，我将不胜感激.

I would be grateful for anyone who gives me a hint about how to solve this problem.

谢谢

推荐答案

幸运的是，您使用的是Mac，因此有一个更简单(但未记录)的方法.

Fortunately, you're using a Mac, so there's a simpler (but not documented) method.

quartz.save('my_filename.png', type='png') 

请注意，您要保存的图像必须是当前活动的石英窗口.

Note that the image you want to save must be the currently active quartz window.
