Answer 1

Hi Dileep!

To insert an image as the background of all slides in a presentation:



PowerPoint.Presentation presentation = Globals.ThisAddIn.Application.ActivePresentation;
float slideHeight = presentation.PageSetup.SlideHeight;
float slideWidth = presentation.PageSetup.SlideWidth;

presentation.SlideMaster.Shapes.AddPicture(
    @"C:\BackgroundImage.jpg",
    Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoTrue, 0, 0, slideWidth, slideHeight);

Answer 2

Hai Jose,
              The above code inserted image as background. But here two problems,
  1)image fit into Presentation. That means , left, right, top, bottom size same as the presentaion size. How can i?

2)after inserting image as background, It will dispaly only when minimize or maximize the powerpoint.
Thanks
Dileep

Answer 3

Hi again!

I edited my code above to make the image size similar to the bounds of the slide.

For your 2nd problem, I'm not sure I understand what you're trying to say.
If the image is supposed to appear when the Powerpoint window is maximized or minimized,
you can try the following:



PowerPoint.Application application = Globals.ThisAddIn.Application;
PowerPoint.Presentation presentation = application.ActivePresentation;
PowerPoint.Shape backgroundImage = presentation.SlideMaster.Shapes.AddPicture(...

if (application.WindowState == PowerPoint.PpWindowState.ppWindowMaximized ||
    application.WindowState == PowerPoint.PpWindowState.ppWindowMinimized)
{
    backgroundImage.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;
}

else
{
    backgroundImage.Visible = Microsoft.Office.Core.MsoTriState.msoFalse;
}

Answer 4

Hai jose,
            My second problem still continues . The background image display only when any refresh(add new slide/minimize/maximize)
 And
my first problem , How can i take slides   left,right,top and bottom.
Thanks
Dilleep

Answer 5

As I've mentioned earlier, I edited my first code to answer your first problem (the one regarding the slide's left, top, width, height).
The left and top parameters correspond to the position of the image on the slide; in this case, they are both zero (positioned at the upper-left corner).

To address your second problem, you might want to hook up my other code to the Application.WindowActivate and Application.PresentationNewSlide events
to determine the visibility of the background image.

Answer 6

Hai Jose,
             Ok  My first problem is solved.
      But the second problem still continue. Here i checked the visibility of background image .it is true.
The interest thing is , The background show the left pane (slide master) and not dispaly in Central pane.If i  minimize the powerpoint (any Refresh method), the the central pane will show the corresponding backgrounds.
Thanks
Dileep

Answer 7

Oh ok, now I get what you mean. : )
I'm not sure if there's a more elegant way to do this, but you can try the following after adding the image to the background:



Globals.ThisAddIn.Application.CommandBars["Thumbnails"].Controls["&Reset Slide"].Execute();

Answer 8

Hai Jose,
             Thank you,
 But i have some doubt about the above code.
What is ["Thumbnails"] ?
What is ["&Reset Slide"].
How it can be fetched?
Thanks
Dileep

Answer 9

Hi Dileep!

If you would right-click any slide on the left pane (list of slides under the Normal view), you would see a popup menu.
This is the "Thumbnails" command bar.
This command bar has an item called "Reset Slide", which you need in order to update the current slide with your background image.
To execute the command that this item represents, you simply call:



Globals.ThisAddIn.Application.CommandBars["Thumbnails"].Controls["&Reset Slide"].Execute();

Answer 10

hai Jose,
 Can i find my background image or other background image by using code.
Thanks
Dileep

Answer 11

hai Jose,
          Please give me the reply.
Thanks
Dileep

Answer 12

Hi!

I think you opened a new thread for this issue. I'll just reply in that thread.

Answer 13

Hai,
         The above code set the background in all slide. But i want to apply the backgrounds selected slide only.
Thanks
Dileep

Answer 14

Hai Jose,
            If
Globals.ThisAddIn.Application.CommandBars["Thumbnails"].Controls["&Reset Slide"].Execute();  is used in powerpoint 2003.

It will get exception. My application is both for powerpoint 2003 and powerpoint 2007.
Thanks
Dileep

Answer 15

Hai Jose,
            If
Globals.ThisAddIn.Application.CommandBars["Thumbnails"].Controls["&Reset Slide"].Execute();  is used in powerpoint 2003.

It will get exception. My application is both for powerpoint 2003 and powerpoint 2007.
Thanks
Dileep

Try the following code instead:


Globals.ThisAddIn.Application.CommandBars.ExecuteMso("SlideReset");

Hai,
         The above code set the background in all slide. But i want to apply the backgrounds selected slide only.
Thanks
Dileep

Then use the Slides collection instead of the SlideMaster:


int indexOfSelectedSlide = 1;
presentation.Slides[indexOfSelectedSlide].Shapes.AddPicture(...

Answer 16

hai Jose,
            The code given below is not add the backgroundImage  of slide. If we use the below code, it fit as slide . But it can be resized.The important thing is , we cant drag the slide background.
              int indexOfSelectedSlide = 1;
presentation.Slides[indexOfSelectedSlide].Shapes.AddPicture(...
Thanks
Dileep

Answer 17

How about the following code?


object indexOfSelectedSlide = 1;
PowerPoint.SlideRange slideRange = presentation.Slides.Range(indexOfSelectedSlide);

slideRange.FollowMasterBackground = Microsoft.Office.Core.MsoTriState.msoFalse;
slideRange.Background.Fill.UserPicture(@"C:\BackgroundImage.jpg");

Answer 18

hai Jose ,
              It is working fine  the selected slide only. But i have one more problems. Now i have two options,
1) apply backgrounds all slides.
2) apply backgrouns selected slide only.
                                                      
              For this , i used the code alredy sent you. My problem is I apply backgrounds to all slide with one image and then selected only one slide  and apply backgrounds to selected slide. In this case the previous background image is not changed. If the slide has no background image, then apply background image to selected slide , now it is working. What is the problem now?
Thanks
Dileep
           

Answer 19

I haven't experienced the problem that you're getting.
It works fine on my machine.
May I see your code?
Does this problem happen on both Powerpoint 2003 and 2007?

Answer 20

hai jose,
      apply all backgrounds , i wrote code below,

PowerPoint.Presentation presentation = Globals.ThisAddIn.Application.ActivePresentation;
float slideHeight = presentation.PageSetup.SlideHeight;
float slideWidth = presentation.PageSetup.SlideWidth; presentation.SlideMaster.Shapes.AddPicture(
    @"C:\BackgroundImage.jpg",
    Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoTrue, 0, 0, slideWidth, slideHeight);
Globals.ThisAddIn.Application.CommandBars["Thumbnails"].Controls["&Reset Slide"].Execute();
  

                                       And
Apply image to as selected Background,i wrote,
 

bject indexOfSelectedSlide = 1;
PowerPoint.SlideRange slideRange = presentation.Slides.Range(indexOfSelectedSlide);

slideRange.FollowMasterBackground = Microsoft.Office.Core.MsoTriState.msoFalse;
slideRange.Background.Fill.UserPicture(@"C:\BackgroundImage.jpg");

The above two code written in Two button events.
Thanks
Dileep

Answer 21

I see. The problem is in your first code.
When you insert the image, it is being inserted as an actual Shape object, not a background.
Your second code works but the image inserted earlier is covering the new background hence you can't see the background.

Try the following for setting the background for all slides:


presentation.SlideMaster.Background.Fill.UserPicture(@"C:\BackgroundImage.jpg");

Answer 22

hai Jose,
              I have one more problems.
 i have three slide. Firstly add background to all slide. It is working . And then i selected the only one slide. And Apply background image to slected slide. Now it is working. Again i add the Background image to all slide  , The previous seleced slide
Background image is not  change.?
Thanks
Dileep

Answer 23

That's because you set the FollowMasterBackground property of the PowerPoint.SlideRange object to false.
Hence, setting again the background of the Slide Master would not affect those selected slides.
You should set that property back to true.



presentation.SlideMaster.Background.Fill.UserPicture(@"C:\BackgroundImage.jpg");

for (int i = 1; i <= presentation.Slides.Count; i++)
{
    presentation.Slides.Range(i).FollowMasterBackground = Microsoft.Office.Core.MsoTriState.msoTrue;
}

Answer 24

Hai Jose,
             Tahnk You Very Much. Now it is working . But I have one or more requirments.

I want to apply an image to all Templates  and selected slide.
Thanks
Dileep
              

Answer 25

Do you need further help on that one?
The process is the same when working with templates.
I am not sure what your requirements are, but I suggest you mark this thread as 'Answered'
and open a new thread if the functionality you want is different from what was discussed in this thread.
It would be easier to follow up our discussion.

Answer 26

Hai Jose,
              I have one or more requirements,
                                                               I have 4 slides, i selected two slide only, I want to apply the backgrounds only selected two slide. How can i do ?

thanks
