Get text from region?

[cew]

Hi,

I have a document with multiple pages that I want to split in single documents for each page.
Now I know that a header is always at the same location on each page. This header I want to use as the new documents filename.


Is it possible to get the text (in my case the header) for a specified region?

Best regards
cew

Hello cew,

I am afraid that your options to extract text with the Viewer are limited - But please have a look at the Get method for text:
In Pseudocode:

Code: Select all

...
// Gets first 10 characters on the page:
DoVerb("Documents[0].Pages[0].Text", "Get", DataIn(0, 10), DataOut, 0);
...

Which should work for your needs.

Best,
Stefan

Sorry, thats not what I need.

I don't know how much characters are in front of the search text and how long it will be.
All I know is the geometric position where it is located.

I need something like this:

Code: Select all

DoVerb("Documents[0].Pages[0].Text", "GetTextInRegion", DataIn(100, 100, 200, 120), DataOut, 0);

where DataIn(100, 100, 200, 120) are the upper left and lower right coordinates of the regions rectangle in pixel or something similar.

I'm afraid there is no simple way to get text from the region, but you can try to use JavaScript to do the job:

Code: Select all

function TextFromRegion(nPage, left, top, right, bottom)
{
  var nWordsCount = this.getPageNumWords(nPage);
  var sText = "";
  for (var i = 0; i < nWordsCount; i++)
  {
    var q = this.getPageNthWordQuads(nPage, i);
    var numQuads = q.length;
    var wordInRect = false;
    for (j = 0; j < numQuads; j++)
    {
      var a = q[j];
      if ((a[0] >= left) && (a[0] <= right) &&
          (a[2] >= left) && (a[2] <= right) &&
          (a[4] >= left) && (a[4] <= right) &&
          (a[6] >= left) && (a[6] <= right) &&
          (a[1] >= bottom) && (a[1] <= top) &&
          (a[3] >= bottom) && (a[3] <= top) &&
          (a[5] >= bottom) && (a[5] <= top) &&
          (a[7] >= bottom) && (a[7] <= top))
      {
        wordInRect = true;
        break;
      }
    }
    if (wordInRect)
    {
      if (sText != "") sText += " ";
      sText += this.getPageNthWord(nPage, i);
    }
  }
  return sText;
}
