Does PDF Creator 1.5 support invisible text (3 Tr)?

Post by MaxMotovilov » Thu Oct 14 2004

I have a number of PDF files that contain scanned page images along with the text generated by an OCR algorithm. The text is rendered in invisible mode (using PDF command 3 Tr). Adobe Reader shows only the images but allows selecting the invisible text. The PDF Creator shown both images and the text in front of them (as if it was rendered in mode 0). Is this a limitation of the product or a feature that can be controlled programmatically?

(I have already submitted this report along with a sample file to the tech. support)

Hello Daniel,

As mentioned in the original post, the PDF Creator has the ability to access text that is generated by a OCR packaged and included with the PDF document.

In order to access this text, you would need to use the ReachText function of the PDF Creator to retrieve a reference to the object. Once you have access to the object you can modify the object's properties.

Hope this helps?

When adding a text object to a pdf document how can you specify that it should be invisible?

Hello,

You can set the 'Hidden' attribute of the Text object to True.

Hope this helps.

Another solution is to set the 'TextRenderingMode' attribute to 3.
