Convert Word DOC to TIFF Image & Retain Orientation of Japanese Characters C# .NET | Tiff Compression & Binarization

Aspose.Words Product Family
1

We are using Aspose.Words 20.9.0. Our problem with rendering Japanese files as TIFFs is that orientation of some characters changes from horizontal to vertical and vice versa. We are using the following save options when generating image:

options.TiffCompression = TiffCompression.Ccitt3;
options.ImageColorMode = ImageColorMode.Grayscale;
options.PixelFormat = ImagePixelFormat.Format32BppArgb;
options.TiffBinarizationMethod = ImageBinarizationMethod.FloydSteinbergDithering;

I am attaching ZIP file with Word document, its rendering with Aspose.Word (with and without markings showing errors) and for comparison its rendering with MS Fax which does not have described issue.

@SamManoff,

Please note that starting from the 21.4 version of Aspose.Words for .NET, advanced typography is now supported when saving to images with GDI+ or SkiaSharp (i.e. on all .NET platforms and .NET Standard). Please try the following C# code:

Document doc = new Document(@"C:\Temp\sample\\Sample.doc");
doc.LayoutOptions.TextShaperFactory = HarfBuzzTextShaperFactory.Instance;
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.Tiff);
options.TiffCompression = TiffCompression.Ccitt3;
options.ImageColorMode = ImageColorMode.Grayscale;
options.PixelFormat = ImagePixelFormat.Format32BppArgb;
options.TiffBinarizationMethod = ImageBinarizationMethod.FloydSteinbergDithering;
doc.Save(@"C:\Temp\sample\21.7.tiff", options);
