Problem rendering EMF

Attachment: Present (inaccessible)

We are evaluating Aspose.Metafiles alongside Aspose.Slides for Java and we like what we see. However, we ran into the following and would like your input.

In testing with some powerpoint presentations that need to be supported, we came across a presentation with an embedded EMF that could not be rendered. I extracted the file from the presentation (using Aspose.Slides) and ran some tests on it.

The file can be rendered by the Microsoft Picture and Fax Viewer and opened in Microsoft Paint, but Aspose.Metafiles seems to have some problems. Rendering the image as a png gives "java.lang.ArrayIndexOutOfBoundsException: Coordinate out of bounds!", and rendering it as a jpeg works, but has incorrect colors and positioning/clipping.

I have attached the EMF, as well as the java code used to convert it to png and jpeg.

Re: Problem rendering EMF

Sorry, hotfix isn't ready yet.
As a temporal workaround you can use the following code:

         BufferedImage image = new BufferedImage(
                     (int)(mfile.getWidth() + 0.5),
                     (int)(mfile.getHeight() + 0.5),
                     BufferedImage.TYPE_3BYTE_BGR);
         Graphics2D graphics = image.createGraphics();
         AffineTransform trans = AffineTransform.getTranslateInstance(-mfile.getMinX(), -mfile.getMinY());
         mfile.playMetafile(graphics, trans);
         javax.imageio.ImageIO.write(image, format, out);

Re: Problem rendering EMF

I'm not in urgent need of a hotfix (yet). Knowing that you've found the problem and are working on a fix is good enough for now.

Thank you!

Re: Problem rendering EMF

Hello Worker.
Please check Aspose.Matafiles 1.3.0.0, it should fix your issue with createDefaultRendering().

This new version does indeed fix the output of my testcase. Thank you.

Unfortunately, it does not fix my problem. My problem is that this metafile appears in a powerpoint presentation, and that rendering the slide with that metafile to an image does not work correctly.

I have attached the presentation that includes the metafile. I have also attached the code I used to generate an image, which is a modified version of the sample code that comes with Aspose.Slides.

If I should re-ask this question in the Aspose.Slides forum, please let me know.

Re: Problem rendering EMF

It appears that the updated Aspose.Metafiles combined with Aspose.Slides for Java 1.8.5.0 completely resolved this issue. Thank you!
