MATLAB图形PDF周围的紧密边界框 [英] Tight bounding box around PDF of MATLAB figure

问题描述

在MATLAB中创建简单图形并将其另存为PDF时，生成的PDF文件将带有一个豪华的边框.

When creating a simple figure in MATLAB and saving it as PDF, the resulting PDF file will have a luxurious bounding box.

plot(1,1,'x')
print(gcf, '-dpdf', 'test.pdf');

(从输出比例看，它们似乎总是放在A页上.)

(From the ratio of the output it seems they always put in on an A page.)

是否有一种简单的方法来获得围绕PDF的紧密边界框?

Is there a simple way to get a tight bounding box around the PDF?

推荐答案

您可以按如下所示设置边框的格式

You can format the bounding box as follows

figure(1)
hold on;
plot(1,1,'x')

ps = get(gcf, 'Position');
ratio = (ps(4)-ps(2)) / (ps(3)-ps(1))
paperWidth = 10;
paperHeight = paperWidth*ratio;


set(gcf, 'paperunits', 'centimeters');
set(gcf, 'papersize', [paperWidth paperHeight]);
set(gcf, 'PaperPosition', [0    0   paperWidth paperHeight]);


print(gcf, '-dpdf', 'test2.pdf');

对于较小的边框，您可以调整paperposition属性，例如

For smaller borders, you can adjust the paperposition property, e.g.

set(gcf, 'PaperPosition', [-0.5   -0.5   paperWidth+0.5 paperHeight+0.5]);
