Usage Examples:
IMAGINGNET-4894 Cloud eps tests are failed on Imaging v21.11 beta
string inputFileName = "test.eps";
string destFilePath = inputFileName + ".png";
using (var image = Image.Load(path))
{
Console.WriteLine(image.BitsPerPixel);
image.Save(destFilePath, new PngOptions());
}
File.Delete(destFilePath);
IMAGINGNET-4885 “Image loading failed.” exception when open TGA document
using (Image image = Image.Load("slow_cape.tga"))
{
image.Save("output.png", new PngOptions());
}
IMAGINGNET-4862 Export SVG with embedded WebP image
using (SvgImage image = (SvgImage)Image.Load(@"D:\input.svg"))
{
image.Save(@"D:\output.webp", new WebPOptions());
}
IMAGINGNET-4834 Tiff to pdf Issue: file size increasing drastically
using (TiffImage image = (TiffImage)Image.Load(@"FX8C0D.TIF"))
{
Aspose.Imaging.ImageOptions.PdfOptions pdfOptions = new Aspose.Imaging.ImageOptions.PdfOptions()
{
ResolutionSettings = new Aspose.Imaging.ResolutionSetting(
image.HorizontalResolution,
image.VerticalResolution),
PdfCoreOptions = new Aspose.Imaging.FileFormats.Pdf.PdfCoreOptions()
{
Compression = PdfImageCompressionOptions.Ccitt4,
}
};
image.Save(@"FX8C0D.pdf", pdfOptions);
}
IMAGINGNET-4752 Incorrect conversion from tif to pdf
string baseFolder = TestDirectory;
string fileName = "Input.tif";
string inputFileName = Path.Combine(baseFolder, fileName);
string outputFileName = inputFileName + ".pdf";
using (Image image = Image.Load(inputFileName))
{
image.Save(outputFileName, new PdfOptions()
{
PdfCoreOptions = new PdfCoreOptions() { Compression = PdfImageCompressionOptions.Ccitt4 }
});
}
IMAGINGNET-4724 Error on use copied TiffFrame
const string filename = "in.tiff";
TiffFrame copiedFrame;
// prepare test data
using (var image = new TiffImage(new TiffFrame(new TiffOptions(TiffExpectedFormat.Default), 100, 100)))
