Matlab:不包含邊界和工具欄的figure(移除保存圖片的白邊)

當我們使用matlab的imshow命令顯示圖片時，會有白框和工具欄出現。在保存圖片時會出現白色的邊框。下面將說明如何去除這些顯示。

Matlab啟動時運行腳本'script.m'，文件位置在~/matlab/ directory。在該文件加上一行，或者在顯示figure時加命令

>>iptsetpref('ImshowBorder','tight');

圖片即可顯示，并且保存時沒有白框。此方法僅僅適用'imshow'命令，不適用'imagesc'命令。

如果在'startup.m'文件中包含以下命令：

%在所有的figure去除菜單欄和工具欄

>>set(0,'DefaultFigureMenu','none');

%'disp'命令顯示無空行

>>format compact;

這三條命令可以去除matlab默認的很多沒有意義的顯示信息。

Something that has bothered me for *the entire* time I’ve used it is that when you show images using ‘imshow’ the resulting figure has the image surrounded in a sea of gray border. Well, I hate that gray border. It serves no purpose and today I have figured

out how to remove it!

Matlab runs a script called ‘startup.m’ when it starts. This is located in your ~/matlab/ directory. If you include this line into that file (or just type it before you make the figure) then you remove the gray border:

>>iptsetpref('ImshowBorder','tight');

Its glorious… Now the picture scales to fill the whole window! (note this only works with the ‘imshow’ command, not ‘imagesc’).

BUT! That’s not all. I also learned about some other cute little tricks that should be included in your startup.m (if you’re me at least).

%removes menu and toolbar from all new figures

>>set(0,'DefaultFigureMenu','none');

%makes disp() calls show things without empty lines

>>format compact;

I feel like these three commands cut a lot of the pointless (inefficient) crap out of Matlab’s default display interface. Thanks to commenter?Matt?who

pointed me toward the set(0,’Default… thing. You can use this to set up *tons* of settings so that you don’t have to set it every time. Just call:

>>set(0,'Default');
