I have an image . I want to show this image app designer with using axes button .
and then use roipoly command to draw a region on that axes button in app designer.
how will I do that ? I couldn't manage it.
I have codes to add image and show it in app designer . With image button I am adding image.
But I can't use roipoly command in app designer. I want to use it when I click second button .
properties (Access = private) t % Using this description
end% Callbacks that handle component events
methods (Access = private) % Button pushed function: SelectAnImageButton
function SelectAnImageButtonPushed(app, event) [filename pathname]= uigetfile({'*.jpg'},"Open file"); fullpathname= strcat(pathname,filename); imgf=imread(fullpathname); if(size(imgf,3)>1) imgf=rgb2gray(imgf); end imshow(imgf,'parent',app.UIAxes); app.t=imgf % t is in here property function and it should be app.t
end % Till here I am adding image and show it in app designer on UIaxes
% And below codes I want to use roiploy command I mean draw a region on app designer on UIAxes but it doesn't work
% Button pushed function: SegmentImageButton
function SegmentImageButtonPushed(app, event) mask=roipoly(app.t); imshow(app.t,'parent',app.UIAxes); end end
