Save exact image output from imagesc in matlab
matlab, matlab-figure
Solution
To save the figure as a file (don't matter how it was created), one should do:
saveas(figureHandle,'filename','format')
where figureHandle could be the `gcf` handle, which means: get current figure.
As pointed in the discussion, if someone doesn't want the ticks to be shown, the person can add:
set(gca,'XTick',[])
set(gca,'YTick',[])
where gca is the handle to the current axis, just as `gcf`. If you have more than one axis, don't forget to "handle the handles". They are returned to you when you create them, i.e.:
hFig = figure(pairValuedProperties); % Create and get the figure handle
hAxes1 = suplot(2,1,1,pairValuedProperties); % Create and get the upper axes handle
hAxes2 = suplot(2,1,2,pairValuedProperties); % Create and get the bottom axes handle
where the pair value are the figure or axes properties declared in the following syntax:
`'PropertyName1',PropertyValue1,'PropertyName2',PropertyValue2,…`
Here are the matlab documentation about the Figure and Axes Properties, and about the saveas method.
Example:
The image saved with the following code:
figure
imagesc(magic(3))
set(gca,'XTick',[]) % Remove the ticks in the x axis!
set(gca,'YTick',[]) % Remove the ticks in the y axis
set(gca,'Position',[0 0 1 1]) % Make the axes occupy the hole figure
saveas(gcf,'Figure','png')
Problem
Hi , I want to save this image produced from `imagesc(magic(3))`, the exact rainbow representation, is it possible? Thanks. This question might look like a duplicate , but it is not . I looked at the solution to the similar question at this site , but it did not satisfy me . I have looked into the Matlab help center and the close answer that I got was this one , at the bottom of http://goo.gl/p907wR
