Add and modify rectangle

[Cosmic2000]

I want to load and display an existing PDF file. That is no problem to me. Than I want to add an red rectangle to the document which is 1 cm high and its width is the page width. The rectangle should be 40% transparent. First the top position of the rectangle should 0 cm from page top. Every time I click a button in my application I want to move the rectangle 2.5 cm downwards. Is this possible? Could you someone provide me an code example for c# or Delphi? I have been searching the docu and forum for hours, but I cant find a solutuon. Thanks in advance.

Hello Cosmic2000,

You could use JS to create the needed rectangle, and then when you click the buttons you have designed, just run some extra JS to move the already created rectangle with the desired offset.
Here is the JavaScript for Acrobat API Reference - the link is to the PDF file directly.

Most of the functions described in the above document are supported in our products and pretty much all of the Annotation functions are (the ones you need), and there should be examples how to execute JS code in the SDK Samples.

Best,
Stefan

OK. Thanks.

I have found this:

Code: Select all

this.addAnnot({Page: 10, type: "FreeText", contents: "test", rect: [5, 10, 100, 100]});

This adds a freetext annotation always at the first page. Why not on page 10? It is always the first page. Every page no is ignored.

Problem 2:
How to provide the values of rect: [...] in millimeters or inch? What is the default measuring unit?

Hi Cosmic2000,

"page" should be lowercase

How to provide the values of rect: [...] in millimeters or inch? What is the default measuring unit?

The rect array consists of four numbers [xll, yll, xur, yur] specifying the lower-left x, lower-left y, upper-right
x, and upper-right y coordinates—in default user space—of the rectangle defining the location of the
annotation on the page. See also the popupRect property.

Best,
Stefan
