Usage Examples:
IMAGINGNET-3438 Add Flat XML ODF Template (.fodg) file format support
string baseFolder = @“D:”;
string inputFile = Path.Combine(baseFolder,“sample.fodg”);
string outputFile = inputFile+".png";
using (Image image = Image.Load(inputFile))
{
image.Save(outputFile, new PngOptions()
{
VectorRasterizationOptions = new OdgRasterizationOptions()
{
PageSize = image.Size
}
});
}
IMAGINGNET-3559 Empty PDF file when saving specific J2K file
string fileName = “sample.j2k”; string baseFolder = “D:”; string inputImage = Path.Combine(baseFolder, fileName); string outputImage = inputImage + “.pdf”; using (Image image = Image.Load(inputImage)) { image.Save(outputImage, new PdfOptions()); }
IMAGINGNET-3405 Allow speed or memory optimization strategies for Jpeg2000 format
// Setting a memory limit of 10 megabytes for target loaded image
// JP2 codec
using (Image image = Image.Load(“inputFile.jp2”, new LoadOptions() { BufferSizeHint = 10 })) {
image.Save(“outputFile.jp2”);
}
// J2K codec
using (Image image = Image.Load(“inputFile.j2k”, new LoadOptions() { BufferSizeHint = 10 })) {
image.Save(“outputFile.j2k”);
}
// Setting a memory limit of 10 megabytes for target created image
// JP2 codec
ImageOptionsBase createOptions = new Jpeg2000Options { Codec = Jpeg2000Codec.Jp2 };
createOptions.BufferSizeHint = 10;
createOptions.Source = new FileCreateSource(“createdFile.jp2”, false);
using (var image = Image.Create(createOptions, 1000, 1000)) {
image.Save(); // save to same location
}
// J2K codec
ImageOptionsBase createOptions = new Jpeg2000Options { Codec = Jpeg2000Codec.J2K };
createOptions.BufferSizeHint = 10;
createOptions.Source = new FileCreateSource(“createdFile.j2k”, false);
using (var image = Image.Create(createOptions, 1000, 1000)) {
image.Save(); // save to same location
}
IMAGINGNET-3420 Exception on converting dng file to png
using (DngImage image = (DngImage)Image.Load(“DNGTest.dng”))
{
image.Save(“result.dng”, new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });
}
IMAGINGNET-3406 Allow speed or memory optimization strategies for Djvu format
// Setting a memory limit of 50 megabytes for target loaded image using (DjvuImage image = (DjvuImage)Image.Load(“test.djvu”, new LoadOptions { BufferSizeHint = 50 })) { for (int pageNum = 0; pageNum < image.Pages.Length; pageNum++) { image.Pages[pageNum].Save(“page” + pageNum + “.png”, new PngOptions()); } }
