How to decrease the size of shading information?

[netsonicyxf]

I tried PDF Editor optimization, but the size of shading information before and after optimization are almost the same.

Hello, netsonicyxf

I dont believe we have any options which would directly impact this area... It may be related to the image compression options by some extension, but thats the best guess I would have. I will admit I don't know that ive ever seen a document with such a large bundle of shading data in the first place.

I shall bring this up to the Dev team to see what, if anything we can do here.

Kind regards,

Hello again!

The Dev team is asking if you could possibly provide a copy of the document in question for the investigation?
Judging by the size shown in your screenshot, You likely wont be able to post it on our forums or by email, so if that is possible, please upload the file here, and let us know when it is complete.

Hello,

Thank you again for the sample, Just wanted to let you know we now have a ticket for this task, to add a way to manipulate this information in the future.

RT#7274: FR: Shading information Optimize - manipulate/reduce

I cannot offer a timeline on this, but know that the dev team is looking into it. In the meantime, I am sorry to say that I do not have any workarounds to offer...

Kind regards,

Hello Daniel,

Thank you for the effort. I believe the optimization will be more powerful in the future release.

Hello,

I just wanted to followup here. The Dev team has come back after the investigation with the following:

There's nothing we can do here. The content was generated like this and is well formed. It's drawn virtually entirely with those shades. They're archived properly, without duplicates for us to remove.

When a content type is as well optimized as it can be, and there are no duplicates or otherwise errors present to remove/adjust, there isn't really anything we can do to "improve" on it further.

Kind regards,
