Usage Examples:
IMAGINGNET-3281 Fix bug in the OdHatchedBrush.Clone
Input file: attachment: HatchedBrush.odg
Output file: attachment: HatchedBrush.odg.png
string inputFileName = Path.Combine("D:", "HatchedBrush.odg");
string outputFileName = inputFileName + ".png";
using(Image image = Image.Load(inputFileName)) {
OdgRasterizationOptions odgRasterizationOptions = new OdgRasterizationOptions();
odgRasterizationOptions.PageSize = image.Size;
image.Save(outputFileName, new PngOptions() {
VectorRasterizationOptions = odgRasterizationOptions
});
}IMAGINGNET-3311 Fix CMX FileFormat: it’s set to Undefined instead of CMX
public void TestCmxImageFormat() {
using(Image image = Image.Load("test.cmx")) {
if (image.FileFormat != FileFormat.Cmx) {
throw new Exception();
}
}
}IMAGINGNET-3261 Optimize JPEG2000 memory usage if possible
using(var image = Image.Load("test.dng"))
using(MemoryStream ms = new MemoryStream()) {
// rendering the image - the exception comes from here
image.Save(ms, new Jpeg2000Options());
// sending the image by HTTP is emulated using the local storage
using(FileStream fs = System.IO.File.OpenWrite("test.j2k")) {
ms.Seek(0, System.IO.SeekOrigin.Begin);
ms.CopyTo(fs);
fs.Flush();
}
}IMAGINGNET-3312 Fix CMX image disposal error when loading from stream
public void TestImageDisposing() {
using(FileStream fs = File.OpenRead("test.cmx")) {
using(MemoryStream input = new MemoryStream()) {
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
input.Write(buffer, 0, buffer.Length);
input.Seek(0, System.IO.SeekOrigin.Begin);
using(Image image = Image.Load(input)) {
using(MemoryStream outStream = new MemoryStream()) {
image.Save(
outStream,
new BmpOptions() {
VectorRasterizationOptions =
new CmxRasterizationOptions() {
Positioning = PositioningTypes.DefinedByDocument,
SmoothingMode = SmoothingMode.AntiAlias,
// the following lines don't affect the error, we can remove them and have the same result
PageWidth = image.Width,
PageHeight = image.Height
}
});
}
}
}
}
}IMAGINGNET-3308 Fix CDR memory leaks which affect Cloud server
input file: attachment: test.cdr
long maxMemoryLeak = 512 * 1024; //512kb
string inputFileName = "D:\\test.cdr";
string outputFileName = "D:\\test.cdr.png";
long beginRam = GC.GetTotalMemory(true);
using(Image image = Image.Load(inputFileName)) {
image.Save(outputFileName, new PngOptions {
VectorRasterizationOptions = new CdrRasterizationOptions {
PageSize = image.Size
}
});
}
long endRam = GC.GetTotalMemory(true);
float result = (endRam - beginRam);
Assert.Less(result, maxMemoryLeak);IMAGINGNET-3239 Incorrect converting EMF to PNG
string path = "D:\\Temp\\";
using(Image image = Image.Load(path + "example.emf")) {
PngOptions pngOptions = new PngOptions();
pngOptions.VectorRasterizationOptions = new EmfRasterizationOptions();
pngOptions.VectorRasterizationOptions.PageWidth = image.Width;
pngOptions.VectorRasterizationOptions.PageHeight = image.Height;
image.Save(path + "example.png", pngOptions);
}IMAGINGNET-3244 CopyFrame lost XMP metadata
public void Test(string imputPath) {
using(TiffImage tiffImage = (TiffImage) Image.Load(imputPath)) {
XmpHeaderPi xmpHeader = new XmpHeaderPi();
XmpTrailerPi xmpTrailer = new XmpTrailerPi(true);
XmpMeta meta = new XmpMeta();
meta.AddAttribute("Test", "12345");
XmpPacketWrapper packetWrapper = new XmpPacketWrapper(xmpHeader, xmpTrailer, meta);
packetWrapper.AddPackage(new PdfPackage());
packetWrapper.AddPackage(new XmpBasicPackage());
tiffImage.Frames[0].XmpData = packetWrapper;
// Assertions XMP metadata in copied frame
using(TiffFrame copiedFrame = TiffFrame.CopyFrame(tiffImage.Frames[0])) {
if (copiedFrame.XmpData != null) {
Console.WriteLine("Xmp data in copied frame is not null");
} else {
throw new Exception("Xmp data in copied frame is null");
}
}
}
}IMAGINGNET-3237 DNG to JPEG conversion fails
using (Image dngImage = Image.Load("1.original.dng"))
{
dngImage.Save("1.original.dng.jpg", new JpegOptions());
}
