How to resize slides to size of presentation

[jinhuang1992]

Hi there,

I'm trying to figure out how to make a slide readjust the sizing of it's shapes and background theme when I change the slide size of the presentation. In PowerPoint, when you change the size, the shapes and background automatically scales to the new size; but when I create a new Presentation instance, set it to a certain size and append slides of different sizes, it doesn't scale to the new size.

I've also tried manually adjusting the shape sizes by the ratio between the new size and old size but that doesn't adjust the background theme's size nor does it scale properly (shapes float outside the page). Am I missing a step? I'm greatly appreciative of any help, thanks!

I have figured out that I have to resize all shapes (shapes from master slides + shapes in all other slides) within the presentation in order for them to be sized correctly when we change the size of a presentation (A4 to Letter etc.).

May I suggest a function that takes SlideSizeType as a parameter on the Presentation class and when this method is called, it resizes all shapes to its correct ratio along with the page size. If I want to resize a presentation, I don't believe we should be required to resize every single shape as well and that's what PowerPoint does when you change the sizing of it.

Thanks in advance!

Dear jinhuang1992,

Many thanks for the detail.
I areadly tested the method you mentioned in the other post, and also found it has some issues, hence I didn't tell you. So sorry for this. And we are doing a new feature which would automatically adjust the size of content on the slide. Once there is no any issue after testing, we will let you know.
So sorry for all inconvenience caused.

One more thing, I was trying to access the master slide's slide layouts, how do I do that?

Dear jinhuang1992,

Thanks for your feedback.
Sorry that Spire.Presentation doesn't support accessing the master slide's slide layouts at present. But we have added it into our schedule. Once there is any progress, we will let you know.

Hi Betsy,

Any update on this? Thanks in advance!

Dear jinhuang1992,

Thanks for your inquiry.
About the feature to automatically adjust the size of content on the slide, there are some issues exist after testing, and our Dev team is still working on it. Once the feature is available, we will let you know.
Regarding the other feature to access the master slide's slide layouts, our Dev team is still investigating and developing, but in development, there are some different opinions between us, so would you please provide us with sample document and point out what you want to access in detail? This would be helpful to detect if the feature can fulfill your requirement when it is achieved.

Great sounds good, and I have attached an example PowerPoint file; If you switch over to the Master Slide View, under the master page are the child slide layouts. I am unable to access the shapes within these slide layouts and make changes to them, I would like to be able to perform actions on these shapes as well. Please let me know if you're still unclear, thanks!
