Aspose Words Metafile Rendering issue

Aspose.Words Product Family

Hi,

In my application I render a preview of a document using Aspose.Words. This document contains metafiles.The rendering of fonts in the metafile is not good, the fonts become all smudgy. I have attached a image to demonstrate this bug.

To debug things for you, I have run into similar problems rendering metafiles using the .net system.drawing API. The problem is that you are rendering to a transparent background. If you change the background color when rendering the image in you code to the document color ( White ) I believe this rendering issue will be resolved.

Thanks

Hi,

Mabey I was not clear enough in my description of the problem.

There is no output document. I am rendering a Aspose.Word.Document page into a System.Drawing drawing context using:

document.RenderToSize(_pageIndex, canvas, 0, 0, Size.Width, Size.Height);

If the document contains a metafile like in the picture presented in my previous post the fonts are drawn all smudgy.

Hope you can help.

Hjörtur.

Hi,

I have attached a image that demonstrates this issue, but I think this happens with all metafiles that contain text.

to replicate :

  1. Create a word document
  2. Drag Image to word document
  3. Save word document
  4. Create a Aspose.Word project
  5. Open saved document and render the first page into a graphics context

Thanks

Hello
Thank you for additional information. I cannot reproduce the problem on my side using the latest version of Aspose.Words (9.3.0). You can download this version from here:
https://releases.aspose.com/words/net
Also please try using the following code:

// Open Document
Document doc = new Document("Doc.docx");
ImageSaveOptions opt = new ImageSaveOptions(SaveFormat.Jpeg);
opt.JpegQuality = 100;
// Save output document
doc.Save("out.Jpeg", opt);

Please see the attached PDF and Jpeg produced on my side.
Best regards,
