Questions before buying

Hi, 
I have a few questions before purchasing the sdk library for both systems:

1) I am not sure what are the difference between Classic_Premium and Master
2) Can be the toolbar be customized (Classic & Master)?
3) For me is important users can select and add images from gallery in their pdfs. Is that possible? With both Sdks?
4) Is there a way to create a page breaks?

Thanks
 

dear user:
the Master edition is fully covered with Classic Edition.
while some features that master edition has, classic edition has not:
--creating tagged PDF.
--add attachment to document.
--text removal.
--image content get/set/remove.
--page content edition.
--field creating.
--PDF to HTML conversion.
--PDF optimize(linearized/compress/PDFA)
--XFDF import/export
--docx support
--draw contents from another document.

2. yes, layout xml in Android project, and storyboard file in IOS project.
3. yes, both SDK support to add images to PDF Page, and then yolu can save the PDF file, by using Page.AddContent(), this feature require premium license.
4. not sure what your mean, if you are saying page break like word document? PDF has no this type character.
    but we can create empty PDF page, and write texts to page, you only need to set font. this also need a premium license.
