javafxsvg's Introduction

JavaFxSVG

A simple library to add SVG support to JavaFX, allowing to use SVG graphics just like any other image type.

More details about the project can be found at the codecentric blog: Adding a custom image renderer to JavaFX 8

Installation

If you are using maven, just add JavaFxSVG to the dependencies

<dependency>
	<groupId>de.codecentric.centerdevice</groupId>
	<artifactId>javafxsvg</artifactId>
	<version>1.3.0</version>
</dependency>

Usage

Add this line to your application:

SvgImageLoaderFactory.install();

preferably before any JavaFX code is executed. After this, you can use SVG images just as any other Image in your application.

If the JavaFX container does not specify any width or height, the image is rendered with default dimensions (currently 400x400). To changes this behavior, a DimensionProvider can be passed with the install command:

SvgImageLoaderFactory.install(new PrimitiveDimensionProvider());

will try to determine the actual size of the SVG (as specified by width and height attributes) and use this as a fallback size.

Known Issues

Currently, SVGs are required to start with either "<svg" or "<?xml" due to some rather static signature matching. As a result, svg might not be displayed when starting with whitespace characters or comment.

Doesn't work after bundling application

After I bundle my application with the badass runtime plugin, it doesn't work. I get a long error: https://hastebin.de/avaxetebuf.sql

NoSuchMethodError with JDK 1.8.0_51

I was faced with this bug when using the latest JDK the version is "build 1.8.0_51-b16". Could you accept my pull request that fix it?

Image height and width not respected

Both fitWidth/Height in an ImageView and width/height when loading an Image do not seem to be respected.

Using version 1.3.0, though the latest tag in the repo is 1.2.1, huh?

Java 9 support

Hi,

I like this library but I was wondering what will happen with it in Java 9?
Internally it uses com.sun.javafx.iio.

Thanks,
Diego

Blurry images

I tried to use javafxsvg but the images are very blurry (see PhoenicisOrg/phoenicis#597).

big size

I used this awesome lib in a 2MB app, but it raised the size to almost 8MB just by using it. Could the size drop in the future or is the "svg support" so resource heavy thing? Thanks

Contribute to OpenJFX

Greetings,

Would you be willing to contribute javafxsvg to openjdk.java.net/projects/openjfx ?

If so, and if there is anything I can do to help, please let me know.

Best regards,
Henri

High DPI displays render blurry SVGs in Java 9+

    private Method lookupScaleMethod() throws NoSuchMethodException {
      Method scaleMethod;
      try {
        scaleMethod = Screen.class.getDeclaredMethod("getScale"); // until 8u51
      } catch (NoSuchMethodException e) {
        scaleMethod = Screen.class.getDeclaredMethod("getRenderScale");
      }
      scaleMethod.setAccessible(true);
      return scaleMethod;
    }

Both of these methods no longer work for determining the scale factor for the screen, but Java 9 introduced the public methods screen.getOutputScaleX and screen.getOutputScaleY which makes the above code obsolete.

I would have made a pull request instead of an issue, but using these new methods would make the new release incompatible with Java 8 and below, and I don't know how the owner of this repo would prefer to deal with that.

If creating a Java 9+ version of this project is acceptable, I can submit a pull request using these methods.

Anti-Aliasing?

First off, I just want to say: I love this loader. Thanks for making it, it really makes working with SVG a breeze.

One thing I noticed is that when the SVG is drawn, it looks kind of pixellated. Is there any way to ensure anti-aliasing is applied and/or a more aggressive version? At the moment, this is what our logo currently looks like using your plugin:

Compared to what it looks like on, say, a browser:

Maven

Hey, i tried today to add your program to test it out
but i got problems with including it into my program.

Is there something wrong with your maven distribution? because in you nexus is no such entry

Add support for retina displays

On retina displays, svgs should be rendered with doubled pixel density. Unfortunately this currently seems to be possible only by adding @2x to the filename. This seems redundant for svg images, so it'd be great to support this without having to duplicate the original image.

Image width and height will be ignored

When you create a image with the width and height parameter set, your SVG-Imageloader will ignore those and pick the default svg-size instead.
new Image("myImage.svg", 100, 100, false, false);
new Image("myImage.svg", 100, 0, true, false);

I debugged a little bit and noticed that BufferedImageTranscoder.setImageSize is called twice. One time with the specified width and height and another time with the default size.
The second time it is called from within SVGAbstractTranscoder.transcode

I really like your SVG support and I'm still using it a lot, but some of my images need to be scaled up first.
Thanks in advanced
