Java 1.6.0_17-b04 with Sun Microsystems Inc. You can check your current Java version in Matlab as follows: As noted, Matlab R2009b (7.9) and onward, at least on Microsoft Windows, pre-bundle a JRE version that does support transparency/opacity and so do not require a retrofit. The JRE can be downloaded from here, and you can configure Matlab to use it according to the instructions here.

If you are using an earlier Matlab release, consider a retrofit of JRE 1.6.0_10 or any later version (e.g., the latest available version today is 1.6 update 24). This means that it’s supported on Matlab release 7.9 (R2009b) and higher by default, and on earlier releases using a JRE retrofit. Setting a figure window’s transparency requires using Java Run-time Engine (JRE) 1.6.0_10 (also called “Java 6 update 10”) or higher. You may also wish to use Malcolm Lidierth’s MUtilities, which also has similar functionalities (plus some other goodies).

I’ve prepared a Matlab utility that contains all these options, including optional blocking/non-blocking fade effects, in my setFigTransparency utility, which is available for download on the Matlab File Exchange. If you fade-out completely (i.e., to a value of 0.0), it might be a good idea to actually close the figure window once it gets the totally-transparent value of 0.0. Of course, you can also fade-in/out to intermediate values such as 0.3 or 0.8. % If blocking, do the fade effect immediatelyĬom.(jWindow,newAlpha) Ĭom.(jFrame,newAlpha) Steps = fix(abs(deltaAlpha) / maxStepAlpha) + 1 NewAlpha = currentAlpha + stepAlpha*stepIdx Ĭom. % If blocking, do the fade effect immediately if blockingFlag || steps= 1 for stepIdx = 1 : stepsĬom. StepDuration = fadeDuration / (steps- 1 ) Steps = fix ( abs (deltaAlpha ) / maxStepAlpha ) + 1 % Compute the required opacity-setting steps

They can be set to any floating-point value between 0.0-1.0, where an opacity of 0.0 means full transparency, and any value in between means partial transparency (i.e., translucency):

Actually, setWindowOpacity sets the opacity level, rather than transparency, but they are obviously complementary and I personally find “transparency” to be more easily understandable.īy default, windows are created with an opacity of 1.0 (= not transparent). Then use Java’s setWindowOpacity method to set the window’s transparency value. Matlab figure window transparencyįollowing an idea I got from Malcolm Lidierth’s MUtilities submission on the Matlab File Exchange, the solution for setting Matlab figure window transparency is quite simple: Get the figure’s underlying Java window reference handle, as in last week’s article. The short answer is that there is no supported way of doing this with pure documented Matlab, but it is trivially easy to achieve using just a bit of Java magic powder (surprise, surprise). This could be used, for example, for window fade-in/fade-out effects. A properly written MATLAB application that needs to use a fixed-width font should set FontName to FixedWidth (note that this string is case sensitive) and rely on FixedWidthFontName to be set correctly in the end-user's environment.Every now and then, a user asks whether it is possible to make an entire Matlab window transparent ( example).

This eliminates the need to hard code the name of a fixed-width font, which may not display text properly on systems that do not use ASCII character encoding (such as in Japan where multibyte character sets are used). set(text_handle,'FontName','FixedWidth').

If you want text to use a fixed-width font that looks good in any locale, you should set FontName to the string FixedWidth: To display and print properly, this must be a font that your system supports. A string specifying the name of the font to use for the text object. FontName A name, such as Courier, or the string FixedWidthįont family. Generally, setting this property to italic or oblique selects a slanted font. MATLAB uses this property to select a font from those available on your particular system. Curly braces | italic | obliqueĬharacter slant. This section lists property names along with the types of values each accepts. To change the default value of properties see Setting Default Property Values.
