 ## About

 TwelveMonkeys ImageIO provides extended image file format support for the Java platform, through plugins for the `javax.imageio.*` package.

-The main goal of this project is to provide support for formats not covered by the JRE itself. 
+The main goal of this project is to provide support for file formats not covered by the JDK. 
 Support for these formats is important, to be able to read data found
 "in the wild", as well as to maintain access to data in legacy formats.
 As there is lots of legacy data out there, we see the need for open implementations of readers for popular formats.

+#### Working with damaged images
+
+When using the normal patterns for loading images, trying to load a damaged image will result in an `IOException` being thrown.
+
+```java
+BufferedImage image = null;
+try {
+    image = ImageIO.read(file);
+} catch (IOException exception) {
+    // Handle, log a warning/error etc
+}
+```
+
+In this scenario, if the image is damaged, and `ImageIO.read` throws an exception, `image` is still `null` - it's not possible for a function to both return a value and throw an exception.
+
+However, in some cases it may be possible to get usable image data from a damaged image. The way to do this is use an `ImageReadParam` to set a `BufferedImage` as a destination.
+
+```java
+int width = reader.getWidth(0);
+int height = reader.getHeight(0);
+ImageTypeSpecifier imageType = reader.getRawImageType(0);
+BufferedImage image = imageType.createBufferedImage(width, height);
+
+ImageReadParam param = reader.getDefaultReadParam();
+param.setDestination(image);
+
+try {
+    reader.read(0, param);
+}
+catch (IOException e) {
+    // Handle, log a warning/error etc
+}
+```
+
+In theory this should work for all plugins, but the result is very much plugin/implementation specific. With some formats and some forms of damaged file, you may get an image that is mostly useful.
+However, you should be prepared for the possibility this just gives a blank or empty image.

 q: What changes do I have to make to my code in order to use the plug-ins?
@@ -492,27 +529,41 @@ q: How does it work?

 a: The TwelveMonkeys ImageIO project contains plug-ins for ImageIO. ImageIO uses a service lookup mechanism, to discover plug-ins at runtime.

+All you have to do, is to make sure you have the TwelveMonkeys ImageIO JARs in your classpath.

 You can read more about the registry and the lookup mechanism in the [IIORegistry API doc](https://docs.oracle.com/javase/7/docs/api/javax/imageio/spi/IIORegistry.html).

 The fine print: The TwelveMonkeys service providers for JPEG, BMP and TIFF, overrides the onRegistration method, and
 utilizes the pairwise partial ordering mechanism of the `IIOServiceRegistry` to make sure it is installed before
-the Sun/Oracle provided `JPEGImageReader` and `BMPImageReader`, and the Apple provided `TIFFImageReader` on OS X, 
+the Sun/Oracle provided `JPEGImageReader`, `BMPImageReader` `TIFFImageReader`, and the Apple provided `TIFFImageReader` on OS X, 
 respectively. Using the pairwise ordering will not remove any functionality form these implementations, but in most 
 cases you'll end up using the TwelveMonkeys plug-ins instead.

 q: Why is there no support for common formats like GIF or PNG?

-a: The short answer is simply that the built-in support in ImageIO for these formats are good enough as-is.
+a: The short answer is simply that the built-in support in ImageIO for these formats are considered good enough as-is.
 If you are looking for better PNG write performance on Java 7 and 8, see [JDK9 PNG Writer Backport](https://github.com/gredler/jdk9-png-writer-backport).


+q: When is the next release? What is the current release schedule?
+
+a: The goal is to make monthly releases, containing bug fixes and minor new features. 
+And quarterly releases with more "major" features.
+
+
+q: I love this project! How can I help?
+
+a: Have a look at the open issues, and see if there are any issues you can help fix, or provide sample file or create test cases for.
+It is also possible for you or your organization to become a sponsor, through GitHub Sponsors. 
+Providing funding will allow us to spend more time on fixing bugs and implementing new features. 
+

 q: What about JAI? Several of the formats are already supported by JAI.

 a: While JAI (and jai-imageio in particular) have support for some of the same formats, JAI has some major issues.
 The most obvious being:
- It's not actively developed. No issues has been fixed for years.
+- It's not actively developed. No issue has been fixed for years.
 - To get full format support, you need native libs.
 Native libs does not exist for several popular platforms/architectures, and further the native libs are not open source.
 Some environments may also prevent deployment of native libs, which brings us back to square one.
