An emf+ picture added to a slide is not rendered

I am using the Microsoft Chart Control to generated a diagram and write it to a memorystream in emfplus format. Next I add this to a slide with a picture frame. This used to work ok in earlier versions of aspose.slide. But not anymore in the latest versions. So I am forced to export the chart in jpeg format.

The following EmfPlus used to work:
chart.SaveImage(ms, ChartImageFormat.EmfPlus);

Now I need to use Jpeg:
var ms = new MemoryStream();
//chart.SaveImage(ms, ChartImageFormat.EmfPlus);
chart.SaveImage(ms, ChartImageFormat.Jpeg);
ms.Position = 0;
var pic = new Picture(slideShow.Presentation, ms);
var idpic = slideShow.Presentation.Pictures.Add(pic);
ms.Dispose();
slide.Shapes.AddPictureFrame(idpic, X0, Y0, W0, H0);

Is EmfPlus support dropped?

Hi Humatix,

Thanks for using Aspose.Slides.

Aspose still supports emf. I have checked by using following code snippet for rendering of emf images on slides.

PresentationEx pres = new PresentationEx();
//Get the first slide
SlideEx sld = pres.Slides[0];

//Add autoshape of rectangle type
int idx = sld.Shapes.AddAutoShape(ShapeTypeEx.Rectangle, 10, 10, 648, 393);
ShapeEx shp = sld.Shapes[idx];

//Set the fill type to Picture
shp.FillFormat.FillType = FillTypeEx.Picture;

//Set the picture fill mode
shp.FillFormat.PictureFillFormat.PictureFillMode = PictureFillModeEx.Tile;

//Set the picture
Image img = new Metafile("D:\\chart_835_524_10.emf");

ImageEx imgx = pres.Images.AddImage(img);

shp.FillFormat.PictureFillFormat.Picture.Image = imgx;

//Write the PPTX file to disk
pres.Write("D:\\Output.pptx");

If this code does not satisfy your requirement please share your working code and reference presentation for further investigation

I appreciate your code.


However,
1. I am not using PresentationEx (Excel 2007) but Presentation (Excel 97 - Excel 2003).
2. I am not using the emf format but the emfplus (or emf+) format.
3. I am not using an autoshape but a Picture and the AddPictureFrame method.
4. I am not loading the image from a file but from a memorystream.

I cannot use PresentationEx because some of our customers want Excel 97 compatible presentations.

Can you confirm that :
1. The emf image that you use is indeed in the emfplus format.
2. That this image is correctly rendered when you add it to a Presentation (not PresentationEx) instance the way I did in my code.

I noticed that the code you provide does NOT include the emf as such in the generated pptx. Wat is included is the png version of the emf file and not the emf file itself.


Using your code the generated pptx file is about 187KB.
Inserting the image manually in PowerPoint 2007 and save the presentation gives a pptx file of about 64KB. The difference almost completely caused by the size of the emf versus that of the png version.

What then, is the point of adding a emf image to a presentation when you loose the vector presentation and hence the scaling abilities?

<span style=“font-size:10.0pt;font-family:“Arial”,“sans-serif””> Hi Humatix,

I am afraid that I could not understand issue exactly, For better understanding of issue, please share your working code and reference presentation for further investigation. Also please share which version of Aspose.Slides you are using.

Please correct me if I am wrong, while using above shared code Aspose.Slides generates pptx having size equal to 90.6 KB and by inserting the image manually in MS PowerPoint 2007 and save the presentation gives a pptx file of about 106KB. (Both pptx are attached herewith)

We are sorry for your inconvenience and really appreciate your patience,

Find attached a copy of my code.

Please note the following:
1. When you open the included TestEmfPlus.emf directly you can see it is a emfplus image where the gradient of the graph bars are rendered as intended.
2. In the generated powerpoint the same image is dittered and the perfect gradient effect is lost. Not something I want to show to our customers.

I am using the latest version of Aspose.Slide (5.9), Visual Studio 2008 and
Windows 7 Professional.

So I repeat my question: is the emfplus format supported in the Presentation class (Exel 97)?

With supported I mean: embedded in the presentation as a scalable vector image (emfplus) without loss of quality and with being converted to a bitmap format like png or jpg.

Hi Humatix,

Please accept my apologies for a late reply.

I have worked with your project file plus reference presentation and able to see the issue of loss of quality in case of saving it in ppt. whereas in case of pptx format it’s not losing its quality.

I have tested the scenario in Aspose.Slides for .NET 5.9.0 and able to reproduce the same problem of losing quality of emf+ image in case of ppt presentation. For the sake of correction, I have logged this issue with ID SLIDESNET-33252 in our issue tracking system. Our development team will look into this issue and you will be updated via this forum thread once it is resolved.


We apologize for your inconvenience.

When can I expect the bug to be fixed. It is more than a month now since you logged the issue with SLIDESNET-33252.

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

I have verified from our issue tracking system and like to share that the issue shared has not yet been resolved. I have requested our development team to schedule the issue. I will share the information with you as soon as the issue is resolved.

We are sorry for your inconvenience and really appreciate your patience,

Thanks for your cooperation.

I am very disappointed that this issue is still not solved in the 6.2.0 release of 2012-05-7.

Can you confirm that the issue will be solved in the next release (6.3)?

Hi Aspose Support team,

We have been facing exact same issue for our project development as well. It would be great if you could help us with the above mentioned issue.

Also it would be great if you could suggest the best image format that can be used for Presentation (Excel 97 - Excel 2003).

Thanks.

M Bhatnagar

Hi M Bhatnagar,


Thanks for your interest in Aspose.Slides.

Can you please share the issue details along with source code and sample images used along with generated output on your end so that I may observe and add that in our issue tracking system.

Can you please re-iterate your statement regarding best image format. Do you mean slide images generated or some thing else. Please share details about this as well so that I may help you further.

Many Thanks,

Hi,We are using DotNet charting to generate a chart and we write it to a memory stream in emfplus format. This used to work fine in the earlier versions of Aspsose.Slides. Following is the code for Presentation Generation( 97 - Excel 2003)

byte[] bytesChartImage = _objChartGenerator.GenerateChartImageStream(chartInstanceID, institutionID, programInstanceID, Constants.EMF_PLUS_Format, shape.Width / 6 , shape.Height / 6 , out p_intErrorCode, p_strUserHierarchyXML);

if (p_intErrorCode == 0)

{

shape.TextFrame.Text = String.Empty;

shape.FillFormat.Type = FillType.Picture;

Picture pic = new Picture(pres, new MemoryStream(bytesChartImage));

int picId = pres.Pictures.Add(pic);

shape.FillFormat.PictureId = picId;

}

The method GenerateChartImageStream above returns a byte array of an image with the format that is specified in the parameter of the method. The above code does not work when we migrated to the latest version of Aspose. The byte array created above is using the EMFPLUS format. We had to forcefully generate a image using the JPEG so as to render the image to the PPT slide.

Just FYI - EMF format renders perfectly on the Presentation (2007) i.e pptx.

Let us know if you need more information.

Thanks.

Manish.

Hi Manish,


I have observed the issue shared by you. Unfortunately, I cannot use the sample code shared by you. Please provide the emf plus image of chart in the form of file and I will try to add that in PPT shape using Aspose.Slides to reproduce the issue further.

Many Thanks,

Hi ,


Please find the attached rar file which contains the EMF format image.

Let me know if you need any more information.

Manish

Hi Manish,


I have observed the image shared and have been able to reproduce the issue specified. I have set the issue priority to High, which is maximum possible priority for normal support forum. I will share the further feedback with you as soon as it will be shared by our development team. I have shared the generated presentation for your kind reference.


Many Thanks,

Hi Mudassir,
