Usage Examples:

IMAGINGJAVA-9275 Implement RasterImage.Create method that provide the ability to create a raster image without specifying its format.

// Creating 32bit raster image in memory
try (RasterImage newImage = RasterImage.create(100, 100))
{
   Graphics gr = new Graphics(newImage);
   gr.clear(Color.getBlue());
   gr.drawRectangle(new Pen(Color.getRed()), 50, 50, 100, 100);
   newImage.resize(450, 450);
   newImage.save("out_image.png"); // we can export the image in any supported format
}
// Creating 32bit raster image in memory, filled with a green color
int[] argb32Pixels = new int[10000];
Arrays.fill(argb32Pixels, Color.getGreen().toArgb());

try (RasterImage newImage = RasterImage.create(100, 100, argb32Pixels))
{
   newImage.save("out_image.png"); // we can export the image in any supported format
}

{

IMAGINGJAVA-9273 CDR rendering produces all-black (PDF/vector) or blank (raster) output

// Code used ---- Case A: CDR > PDF produces an all-black page ----
try (Image image = Image.load("Monthly Music - 03 March.cdr"))
{
	image.save("out.pdf", new PdfOptions()
		{{
			setVectorRasterizationOptions(new CdrRasterizationOptions()
			{{
				setPageSize(Size.to_SizeF(image.getSize()));
				setPositioning(PositioningTypes.DefinedByDocument);
				setBackgroundColor(Color.getWhite());
			}});
		}});
}

// ---- Case B: CDR > PNG produces a blank image ----
try (Image image = Image.load("Monthly Music - 03 March.cdr"))
{
	image.Save("out.png", new PngOptions()
			{{
				setVectorRasterizationOptions(new CdrRasterizationOptions()
				{{
					setPageSize(Size.to_SizeF(image.getSize()));
					setBackgroundColor(Color.getWhite());
				}});
			}});
}

{

IMAGINGJAVA-9272 The feasibility of iterating over SVG file content

try (SvgImage image = (SvgImage)Image.load("sample_car.svg"))
{
    List<AsposeSvgNode> objects = image.getSvgObjects();
    String findId = "path3043";
    System.out.println("Number of entries: " + objects.size());

    for (AsposeSvgNode obj : objects)
    {
        if (findId.equals(obj.getPropertyValue("id")))
        {
            System.out.println("Content of entry ID: " + findId);
            System.out.println(obj);
            break;
        }
    }
}
