matlab保存图片清晰度_图片分辨率300dpi怎么设置

大家好，又见面了，我是你们的朋友全栈君。

用print函数：

如：t=1:100

plot(t,sin(t));

print(gcf,’-dpng’,’sin.png’);

用saveas()

如：t=1:100;

plot(t,sin(t));

saveas(gcf,’my_picture.bmp’,’bmp’);

print(‘-depsc’,’-tiff’,’-r300′,’picture1.eps’)

%满足dpi的要求

saves the current figure at 300 dpi, in a color Encapsulated

PostScript file named picture1.eps. The -tiff option creates a 72

dpi TIFF preview, which many word processor applications can

display on screen after you import the EPS file. This enables you

to view the picture on screen within your word processor and print

the document to a PostScript printer using a resolution of 300

dpi.
