WMF font spacing problem

Hi there,

I have an app that generates slides containing scaled wmf documents, in a web farm of 6 servers,

2 of the servers are creating Slides with fonts that are incorrectly spaced !! (bottom ppt in attached image)

whilst the rest are correct (top ppt in the attached image),

FYI

I have been informed that the servers are all identical, any ideas ?

I'm using aspose slides 2.7.2.0

If I dump the wmf straight out of the app it looks ok on all servers,

Note :

height/width is calculated as Math.Round(((4.49) * .3942) * 576),0)

The actual wmf size is 46.57 cm x 46.57 cm

If I edit the WMF (righ click edit picture ( the text spacing corrects itself )

below is the code to add a wmf to the slide....

System.IO.MemoryStream ms = new System.IO.MemoryStream(PPUP.FILEDATA);

System.Drawing.Imaging.Metafile meta = new System.Drawing.Imaging.Metafile(ms);

Picture objPicture = new Picture(Tombpres, meta);

int objPictureID = Tombpres.Pictures.Add(objPicture);

PictureFrame objPictureFrame = objSlide.Shapes.AddPictureFrame(objPictureID, xpos, ypos, pictureWidth, pictureHeight);

It seems that fonts are not installed on other two servers , probably some of the fonts are missing there.

Hi there, The installed fonts are identical on all machines !

Any other ideas ?

Hello,

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Please check, if it is a trust level problem.

Aspose.Slides must use System.Drawing.Imaging.Metafile class to open and render presentations with wmf/emf metafiles. By unknown reasons Microsoft's .Net framework doesn't allow this class to work with Medium trust level. It works in Full trust mode only. So it looks like currently Aspose.Slides can't process presentations with metafiles in Medium trust.

Please provide your source presentation, in case, it is not resolved, so we could investigate it.

  • C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config - no reference to trust level
  • C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\CONFIG\machine.config - trust level is set to full ()
  • application web.config - no reference to trust level

  • Is there anything else ?

    Try the full trust level in your web.config file e.g

    <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

    Settings in web.config file takes precedence over the machine.config file.

    Sorry it did not work !

    I have set the trust level to full, however the wmf fonts spacing is still incorrect on some of the web farm servers.

    Any other ideas ?

    Hi there, Just chasing this problem, have you a solution yet ?

    I have requested the technical team lead to help you. He will help you as soon as possible. Thanks for your patience.

    Try to add metafile as stream instead of System.Drawing.Imaging.Metafile.

    System.IO.MemoryStream ms = new System.IO.MemoryStream(PPUP.FILEDATA);

    Picture objPicture = new Picture(Tombpres, ms);

    int objPictureID = Tombpres.Pictures.Add(objPicture);

    PictureFrame objPictureFrame = objSlide.Shapes.AddPictureFrame(objPictureID, xpos, ypos, pictureWidth, pictureHeight);


    There can be too many possible reasons so it would be great if you can provide metafile and both presentations with wrong and correct font spacing. May be servers have different .Net runtime version. May be some of them don't have GDI+.

    The suggested solution worked,

    Thanks for you all help on this.
