How to save figures to pdf as raster images in matplotlib

Question

I have some complex graphs made using matplotlib. Saving them to a pdf using the savefig command uses a vector format, and the pdf takes ages to open. Is there any way to save the figure to pdf as a raster image to get around this problem?

Answer 1

您可以强制将单个图形元素栅格化，如下所示：

text(1,1,'foobar',rasterized=True)

Answer 2

我不知道，但是您可以使用“转换”程序（ImageMagick）将jpg转换为pdf：`convert file.jpg file.pdf'。
