导出Matlab图为PNG？ [英] Export Matlab figure as PNG?

问题描述

我需要自动将Matlab导出到PNG。我的数字大小为600x200像素：

  hFig = figure（1）; 
 set（hFig，'Color'，[1 1 1]）; ％backgroundcolor white 
 set（hFig，'Position'，[500 500 600 200]）％size 600x200 
  

$ b $我尝试过例如

  print -dpng image.png 
  

，但image.png大于600x200像素。使用保存按钮从图形窗口GUI手动导出图形非常好，我想从脚本中自动执行。感谢任何提示！

解决方案

我也知道数字保存的问题与屏幕上看起来一样。

有可能为您工作的 saveas 命令，但也有一些解决方案改变了我。

只有我知道的方法是仔细设置每个方面：

  set（gcf， 'PaperUnits'，'inches'，'PaperSize'，[2,6]，'PaperPosition'，[0 0 2 6]）
 print（' -  dpng'，' -  r100'，'test' b $ b  

（所以纸张尺寸为2x6，打印为100dpi，PaperPosition非常重要，边框。）

I need to automatically export figures from Matlab to PNG. My figure has a size of 600x200 px:

hFig = figure(1); 
set(hFig, 'Color', [1 1 1]); % backgroundcolor white
set(hFig, 'Position', [500 500 600 200]) % size 600x200

I tried e.g.

print -dpng image.png

but the image.png is larger than 600x200 px. Exporting the figure manually from the Figure Window GUI using the "save" button works great, I want to do exactly this automatically / from a script. Thanks for any hint!

解决方案

I also know the problem that figures save never look the same as on screen.

There is the saveas command which might work for you - but does also some resolution changing for me.

Only way I know is to carefully set every aspect like this:

set(gcf,'PaperUnits','inches','PaperSize',[2,6],'PaperPosition',[0 0 2 6])
print('-dpng','-r100','test')

(so paper size is 2x6" and print with 100dpi, PaperPosition is important as you will have otherwise some extra border.)
