使用ImageMagick将PDF转换为PNG [英] Convert PDF to PNG using ImageMagick
问题描述
使用ImageMagick,我应该使用什么命令将PDF转换为PNG?我需要最高质量,最小的文件大小。这就是我到目前为止(顺便说一下):
using ImageMagick, what command should i use to convert a PDF to PNG? I need highest quality, smallest file size. this is what I have so far (very slow by the way):
convert -density 300 -depth 8 -quality 85 a.pdf a.png
看看Gmail在用户查看PDF时的作用,质量太棒了,文件大小非常小。 DPI只有96(我必须设置密度为300以获得任何体面)。谁知道GMail是怎么做到的?谢谢。
Looking at what Gmail does when a user "view" a PDF, the quality is awesome and the file size very minimal. The DPI is just 96 (I have to set a density of 300 to get anything decent). Anyone know how GMail does it? Thanks.
推荐答案
当你将密度设置为96时,它看起来不是很好吗?
when you set the density to 96, doesn't it look good?
当我尝试它时,我看到保存为jpg导致更好的质量,但更大的文件大小
when i tried it i saw that saving as jpg resulted with better quality, but larger file size
