Usage Examples:

IMAGINGJAVA-7786 Support export to Dxf format in Aspose.Imaging

String inputFileName = "Pooh group.eps";
String outputFilePath = "result.dxf";
try (Image image = Image.load(inputFilePath))
{
     DxfOptions options = new DxfOptions();
     options.setTextAsLines(true);
     options.setConvertTextBeziers(true);
     options.setBezierPointCount(20);
     image.save(outputFilePath, options);
}

IMAGINGJAVA-7771 Eps can not be converted to vectorized APS (to svg for example)

String fileName = "Pooh group.eps";
String baseFolder = "D:\\";
String inputFileName = baseFolder + fileName;
String outputFile = inputFileName + ".svg";
try (EpsImage image = (EpsImage)Image.load(inputFileName))
{
    image.save(outputFile, new SvgOptions());
}

IMAGINGJAVA-7769 Fix exception with reading CDR

java
String baseFolder = "D:\\cdr\\";
String[] files = new String[] { "book work_1to19.cdr", "Backup_of_PTERR.cdr", "PTERR.cdr", "PTERR_2.cdr", "VECTOR SSV.cdr" };
int[] positioning = new int[]
		{
				PositioningTypes.DefinedByDocument, PositioningTypes.DefinedByDocument, PositioningTypes.DefinedByDocument,
				PositioningTypes.DefinedByDocument, PositioningTypes.Relative
		};

for (int i = 0; i < files.length; i++)
{
	String fileName = files[i];
	String inputFilePath = baseFolder + fileName;
	String outputFilePath = inputFilePath + ".png";
	try (CdrImage image = (CdrImage)Image.load(inputFilePath))
	{
		CdrRasterizationOptions vector = new CdrRasterizationOptions();
		vector.setPositioning(positioning[i]);
		final PngOptions options = new PngOptions();
		options.setVectorRasterizationOptions(vector);
		image.save(outputFilePath, options);
	}
}

IMAGINGJAVA-7768 ImageLoad exception on loading TGA image

try (TgaImage image = (TgaImage)Image.load("GoldBorder.tga"))
{
    image.save("output.tga.png", new PngOptions() {{ setColorType(PngColorType.TruecolorWithAlpha); }});
}
