Page renumbering

[anovy]

Hi,
On your PDF-Tools SDK web page you advertise this:

New Placement functionality for watermarks and also Text masking and Replacement functionality to allow page renumbering etc on merged/extracted PDF files.

Unfortunately in the documentation I cannot find anything about this. Do you have some guidelines how to achive the page renumbering for merged or extracted PDF files (what API functions to use and how)?

Actual text replacement is theoretically possible using the low level API - but as the doc's state - there is no support given for the low level API and you will need to be extremely proficient and knowledgeable in regards the PDF format itself to achieve this - but there is a simpler way ...

Using the watermark function to overlay a text box with the required values along the footer location (for example).

So if I good understand, the advertised "Text masking and Replacement functionality" can be used only by the supreme PDF professionals (as you)? And it is without any support? So why you advertise this among the main PDF-Tools features on your web page for regular developers?

Anyway, do you provide at least some support (help, guidelines) for the mentioned watermark method? Can this be achieved by a text watermark, or only by image watermark? And how I can recognize what text represents the header or footer, its size and position etc.?

[John - Tracker Supp]

Replacement and masking of text is achieved by using the watermark functions - either text or image based watermarks.

The use of the Low Level API and the ability to do certain things is clearly stated where applicable and we do not suggest anywhere that you can directly edit text objects or any page level objects using any of our products - except by using the low level API !

Use of watermarks is demonstrated in several of the example apps provided - please investigate them ...

As to placement - this is done on a co-ordinate basis - so you will need to establish where on the page you wish to place the text/image watermarks accordingly.

Thank you. Could you please also explain if the headers and footers are special entities? By other words: The question is, if I can recognize, what text element is header or footer, so I will know what text to cover by watermark.

[John - Tracker Supp]

It is highly unlikely you will be able to recognise by anything other than the position visually - but if you upload a couple of sample pages showing what you need to replace - once seen, we can comment further - please zip any pages/files before uploading.

I think it is not necessary at the moment. I just needed to know if the headers/footers are some special entities in PDF hierarchy, or if they are just standard text as any other text. Thank you.

Ok - good luck.
