ggplot2:方面标签模糊 [英] ggplot2: blurry facet labels
问题描述
保存ggplot
图形时-无论我使用ggsave()
还是例如png()
-刻面标签看起来模糊.例如,下面的代码将生成刻面标签"F",其外观类似于下图,并且在文本栅格的外部像素上着色.
When I save a ggplot
figure -- regardless of whether I use ggsave()
or e.g. png()
-- the facet labels come out looking blurry. For example, the following code produces a facet label 'F' that looks like the picture below, with coloration on the outer pixels of the text raster.
ggplot(data.frame(x=1, y=1, f='F'), aes(x, y)) +
facet_grid(. ~ f)
ggsave('foo.png')
提前感谢您的任何建议!
Thanks in advance for any advice!
PS-根据@Brian的要求,我正在更新此帖子,以指出我使用的是Windows计算机.
PS -- As per @Brian's request, I'm updating this post to note that I'm using a Windows machine.
PPS-这次我要再次更新我的帖子,以澄清我打算将图形插入Word.因此,根据这篇文章,我想使用基于像素的格式(例如PNG),而不是基于矢量的格式(例如PDF).
PPS -- I'm updating my post again, this time to clarify that I plan to insert the figure into Word. So as per suggestion #4 from this post that @Masoud pointed me to, I would like to use a pixel-based format (e.g. PNG) rather than a vector-based format (e.g. PDF).
推荐答案
尝试禁用抗锯齿
默认(石英):
ggsave('foo.png', antialias="none")
