matlab GUI saves images on axes (coordinates)

1. Default way

The save image of the matlab GUI default menu defaults to keep the full GUI, including using "Menu->Edit->Copy Graphics".

2 Save the visible area

2.1 Code

[FileName,PathName] = uiputfile({'*.jpg','JPEG(*.jpg)';...
                                             '*.bmp','Bitmap(*.bmp)';...
                                             '*.gif','GIF(*.gif)';...
                                             '*.*',  'All Files (*.*)'},...
                                             'Save Picture','Untitled');
if FileName==0
      disp('保存失败');
      return;
else
      h=getframe(picture);%picture是GUI界面绘图的坐标系句柄
      imwrite(h.cdata,[PathName,FileName]);
end           

2.2 Description

The function getframe() is to obtain a frame of image in the coordinate axis, and the returned object has two members, cdata and colormap.

3 Save the area with the axes

3.1 Code

new_f_handle=figure('visible','off');
new_axes=copyobj(picture,new_f_handle); %picture是GUI界面绘图的坐标系句柄
set(new_axes,'units','default','position','default');
[filename,pathname,fileindex]=uiputfile({'*.jpg';'*.bmp'},'save picture as');
if ~filename
     return
else
      file=strcat(pathname,filename);
      switch fileindex %根据不同的选择保存为不同的类型
      case 1
                  print(new_f_handle,'-djpeg',file);
      case 2
                  print(new_f_handle,'-dbmp',file);
      end
end
delete(new_f_handle);

3.2 Description

In fact, a new coordinate graph is created, the GUI is copied to the new image, the new image is output, and finally the newly created graph handle is deleted.
