我最近一直在尝试在MATLAB中创建一个自定义尺寸的图形，并使用saveas函数自动将其保存.特别是，在以我创建文件的大小保存文件时遇到了问题.粗略地说，我的代码如下:

I have recently been trying to create a custom-sized graph in MATLAB and save it automatically using the saveas function. In particular, I am having issues saving the files in the size that I create them. Roughly speaking, my code is as follows:

mygraph = figure('Position',[1,20,1280,1024]);
% creates a figure positioned 1 px from the left of the screen
% 20 px from the bottom of the screen
% that is 1280 px in length and 1024 px in height

% some code to create graph

saveas(mygraph,'mygraphfilename','emf')
% saves figure as mygraphfilename.emf. 

到目前为止，我的代码可以正常工作，因为它可以在屏幕上创建自定义大小的图形，但是似乎可以将图片本身保存为默认大小.奇怪的是，如果我不使用saveas函数并手动保存图形，那么图像将保持其大小.

So far, my code works fine in that it can create a custom sized graph on my screen, but it seems to save the pictures themselves in a default size. The weird thing is that if I do not use the saveas function and save the figure manually, then the image retains its size.

为了澄清起见，我目前将图形另存为emf，不过如果可行的话，我也愿意使用jpg/png/bmp.

For clarification purposes, I'm currently saving the graphs as emf, though I'm also open to using jpg/png/bmp if works fine too.

推荐答案

尝试设置以下内容:

set(mygraph, 'PaperPositionMode','auto')     %# WYSIWYG
print -dmeta -r0 file.emf
