Problem Merging slides

Good morning!

I’m working right now in an application made in Ruby on Rails that needs to process every day a lot of PPT / PPTX files, the app name is Slidetown (Is in development phase).

We are implementing the shopping cart. In this shopping cart the user built his own presentation to download, but when we are trying to merge all slides with saaspose api the result is not good, because some images despairs and the presentation format is not correct.

Those are 3 examples for merge that we did:

If you want, please feel free to register in http://slidetown.herokuapp.com/
and make your own test adding multiple slides in the shopping cart, and going to checkout (Your won’t pay for it, don’t worry)

This is the MAIN feature of the application, and it’s so IMPORTANT for us, please help us.

As always, Thanks for your help!

PD: I can send you the ruby code if you want, but it’s only a HTTP request to the API, it is not a complex code.

Finally I found a way to show exactly the problem, there is a video with
the merge problem (Please open in fullscreen):

And this is the code that we use in the video:

signed_url = Saaspose::Utils.sign("slides/order_example.ppt/merge",
{:storage => "Saaspose"})
merge_with =
RestClient.post(signed_url, merge_with, :content_type =>
Saaspose::Utils.sign("storage/file/order_example.ppt", {:storage =>

The files still in the Saaspose repo (The files are the previous "Test 1"

Thank you so much for your help!

Hi Moises,

Thanks for your inquiry and sorry for the delayed response. From the provided video link, I'm able observe that you can merge these presentations but Saaspose service is generating an incorrect results e.g. missing images, incorrect format etc. As I shared earlier, It is the fault of Saaspose service and I've logged this problem under ticket id SAASSLIDES-110. It is working fine with our latest code base ( without using Saaspose Service ). It will be fixed when we will integrate Saaspose service with our latest code base.

Please let us know in case of further assistance and comments.


Thanks for your answer,we appreciate your help.

As I told you before, this is a main feature of Slidetown, and we are close
to launch the app.

Is important for us to know when are you going to integrate your latest
Saaspose service code base with this fixbug? (SAASSLIDES-110)

Thanks for your help!

Hi Moises,

Thanks for your inquiry. I have asked the responsible developer to share ETA about this issue. As soon as any information is shared with me, I will be more than happy to share that with you. Please spare us a bit more time.
