Display image using GUI MATLAB in a specific region
I'm looking for how can I display an image in my GUI in a specific region of my interf开发者_高级运维ace.
In GUIDE, you can draw axes into the GUI. Then, in a callback function, you can plot an image into the axes.
Personally, I would rather not have the image inside the GUI, because it makes it harder to resize everything properly, and if you want to have a closer look at the image, or capture it to paste into another application, having the figure as part of the GUI can be inconvenient. Thus, I prefer to have the image open in a separate figure window.
Try the following code:
function movingimage
%# Plotting a figure
fig1=figure('Name','Plotting an image',...
'Unit','normalized', 'Position',[.1 .1 .8 .8]);
uicontrol(fig1,'Style','text','Unit','Normalized',...
'Position',[.9 .85 .1 .07],'String','Press the button below to move the image location.');
uicontrol(fig1,'Style','pushbutton','Unit','Normalized',...
'Position',[.9 .8 .05 .05],'String','Move','Callback',{@action_Callback});
%# Say, you wish to plot an image of relative dimension (.3 x .3) to the figure.
xdim=.3; ydim=.3;
%# Image's movable range in x is (1 - xdim)
dx=1-xdim;
%# Image's Movable range in y is (1 - ydim)
dy=1-ydim;
%# considering the size of the image...
pos = [.5*dx .5*dy xdim ydim]; %# Initial location of the image is at the center of the figure.
ax1 = axes('position',pos);
img = load('mandrill');
image(img.X)
colormap(img.map);axis off;axis equal;
function action_Callback(hObj,eventdata)
pos=[rand(1)*dx rand(1)*dy xdim ydim];
set(ax1,'position',pos);
end
end
The most direct and easy way I find to do this is to use the Axis component as shown in this tutorial:
