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))
{, new PngOptions());

IMAGINGJAVA-8115 Duplicate tiff frame results in a wrong colors (almost completly dark)

import com.aspose.imaging.Image;
import com.aspose.imaging.fileformats.tiff.TiffFrame;
import com.aspose.imaging.fileformats.tiff.TiffImage;
import com.aspose.imaging.fileformats.tiff.TiffRational;
import com.aspose.imaging.fileformats.tiff.enums.*;
import com.aspose.imaging.imageoptions.TiffOptions;

try (TiffImage source = (TiffImage) Image.load("image.tiff"))
	TiffOptions options = new TiffOptions(TiffExpectedFormat.Default);
	options.setBitsPerSample(new int[] {8, 8, 8});
	options.setXresolution(new TiffRational(72));
	options.setYresolution(new TiffRational(72));

	try (TiffImage tiffImage = new TiffImage(new TiffFrame(options, 1, 1)))
		// Iterate over the collection of input image frames
		for (TiffFrame frame : source.getFrames())
			TiffFrame copiedFrame = TiffFrame.copyFrame(frame);

			// Add copied frame to the destination image

		// The first frame is created by default, we may just remove it as it is empty
		// But it is not possible to remove the empty frame unless there are more than one frames
		final TiffFrame[] frames = tiffImage.getFrames();
		if (frames.length > 1)
			// Set next frame as Active
			// Remove the first frame

		// Save result image"image.tiff.tiff");

IMAGINGJAVA-8112 Incorrect export from SVGZ to PNG on Linux

**Please, execute this code in the Linux system**

try (com.aspose.imaging.Image image = com.aspose.imaging.Image.load("example.svgz"))

*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"))
