I have two figure windows that display images. We can set the white portion of the image to be transparent so that it will show the background color of the pushbutton (in our example, ‘green’). The other option should be at the beginning of the code. Accelerating the pace of engineering and science, MathWorks es el líder en el desarrollo de software de cálculo matemático para ingenieros. Save Figure with Specific Size, Resolution, or Background Color. 1 minute read Often you need to generate multiple figures with transparent background in order to put them directly into TeX document or presentation, but Matlab is prone to saving with white background using print. For constant transparency across the entire patch, set the FaceVertexAlphaData to a constant between 0 (fully transparent) and 1 (fully opaque), and set the FaceAlpha property to 'flat'. This command sets the boundary area for all figures to white. You can set it to the figure background color like Matt suggests. Reload the page to see its updated state. This is the red in the pictures above. Then create new gimp window with background option as tranperancy, and paste it into that and export that as png. Vote.
