Usage examples:
IMAGINGNET-2973 Setting for replacing missing fonts when saving ODG, SVG and MetaFile Images
FontSettings.DefaultFontName = "Comic Sans MS";
string[] files = new string[] { "missing-font.emf", "missing-font.odg", "missing-font.svg", "missing-font.wmf" };
VectorRasterizationOptions[] options = new VectorRasterizationOptions[] { new EmfRasterizationOptions(), new MetafileRasterizationOptions(), new SvgRasterizationOptions(), new WmfRasterizationOptions() };
for (int i = 0; i < files.Length; i++)
{
string outFile = files[i] + ".png";
using (Image img = Image.Load(files[i]))
{
options[i].PageWidth = img.Width;
options[i].PageHeight = img.Height;
img.Save(outFile, new PngOptions()
{
VectorRasterizationOptions = options[i]
});
}
}IMAGINGNET-2941 RasterImage to PDF
public void DicomToPdf()
{
string inputFile = "RleOnePage.dicom";
string outputFile = "RleOnePage.dicom.pdf";
using (RasterImage image = (RasterImage)Image.Load(inputFile))
{
image.Save(outputFile, new PdfOptions());
}
}
public void DngToPdf()
{

}IMAGINGNET-2985 Incorrect conversion from PSD to JPEG
To disable alpha blending explicitly, a new flag JpegOptions.PreblendAlphaIfPresent has been introduced. Please use the following code to convert PSD to JPEG without alpha blending:
string dir = @"c:\aspose.work\IMAGINGNET\2985\";
string sourcePath = dir + "alphachannel.psd";
string outputPath = dir + "alphachannel_out.jpg";
PsdLoadOptions loadOptions = new PsdLoadOptions();
loadOptions.ReadOnlyMode = true;
JpegOptions saveOptions = new JpegOptions();
saveOptions.PreblendAlphaIfPresent = false; // Disable alpha blending!
using (PsdImage image = (PsdImage)Image.Load(sourcePath, loadOptions))
{
image.Save(outputPath, saveOptions);
}IMAGINGNET-2977 Using of CMYK color profile for PSD image produce differ from Photoshop colors
string sourceFileName = "otameshitameshi-cmyk(1).psd";
using (PsdImage image = (PsdImage)Image.Load(sourceFileName))
{
image.UseRawData = true;
TiffOptions options = new TiffOptions(TiffExpectedFormat.TiffLzwCmyk);
options.IccProfile = image.CmykColorProfile.Stream as MemoryStream;
image.Save("result.tiff", options);
}IMAGINGNET-2945 Png image not properly converted to JPEG
source file: picture.png
result file: picture.png.jpg
string folder = @"D:\";
string fileName = "picture.png";
string inputFile = Path.Combine(folder, fileName);
string outputFile = Path.Combine(folder, fileName+".jpg");
using (Image image = Image.Load(inputFile))
{
JpegOptions jpegOpt = new JpegOptions
{
ColorType = JpegCompressionColorMode.Rgb,
Quality = 60,
CompressionType = JpegCompressionMode.Baseline,
Jfif = new JFIFData()
{
DensityUnits = JfifDensityUnits.PixelsPerInch,
XDensity = 100,
YDensity = 100
}
};
image.Save(outputFile, jpegOpt);
}IMAGINGNET-2936 Wrong conversion to TIFF when used CMYK profile with TiffExpectedFormat.TiffLzwCmyk mode
Input files: cmyktataro.psd, otameshitameshi-cmyk.psd
Output files: cmyktataro.psd.tif, otameshitameshi-cmyk.psd.tif
string[] fileNames = new string[] { "cmyktataro.psd", "otameshitameshi-cmyk.psd" };
string folder = @"D:\tiff";
foreach (var fileName in fileNames)
{
string inputFile = Path.Combine(folder, fileName);
