MATLAB: Can I increase the size of a pixel when creating a png file

imdilateimshowMATLAB

I am creating a png file but the pixels are not visible. Is it possible to increase the pixel size?

Best Answer

There is no direct way, but you can use 'IMDILATE' to dilate the pixels. For instance, you can use the following commands:
%Using imdilate
>> se = strel('line',11,90);
>> img = imdilate(rgb1,se); %rgb1 is the matrix
>> imshow(img) %save the figure as png file
>> saveas(gcf,'myfile.png')
Also, note that the above functions require Image Processing Toolbox.For more information, refer to the following documentation link:
