Usage Examples:

IMAGINGJAVA-8116 Exception on converting EMF to PNG

String baseFolder = "D:\\";
String file = "BetterEMF.emf";
String inputFileName = baseFolder + file;
String outputFileName = inputFileName + ".png";
try (Image image = Image.load(inputFileName))
{
	image.save(outputFileName, new PngOptions());
}

### GIF export to APNG:

try (Image image = Image.load("gif-image.gif"))
{
    image.save("output.png", new ApngOptions() {{ setFullFrame(true); }});
}

*Note that you should provide `FullFrame = true` for `new ApngOptions()` to get rid of artifacts.*

### Saving GIF frames as HTML5 images:

try (GifImage image = (GifImage)Image.load("gif-image.gif"))
{
	Image[] pages = image.getPages();
	for (int i = 0; i < pages.length; i++)
	{

	}
}

IMAGINGJAVA-1573 Exception on saving DICOM image

try (Image image = Image.load("sample.dcm")
{
	image.save("sample.dcm.jpeg", new JpegOptions());
}
