PXO_InputField

Post by Tom Princen » Tue Jun 07, 2016 8:35 pm

How do I calculate the coordinates (left, right, upper,...)?

In the help I find this quote “The unit is points (72 per inch).” But this does not seem correct?

Hello Tom,

Can you please provide a snippet of the code you are trying to use, and comment why you think the result is not correct?

Regards,
Stefan

PXO_InputField MyInputField = PXO_InputField();

MyInputField.top = 0;
MyInputField.bottom = 100;

MyInputField.left = 403;
MyInputField.right = 604;

MyInputField.nPage = 0;


OCR_GetField(pdf, ref Options, out TextOut, Zone, (uint)PXO_FieldInputFlags.PXO_Origin_TopLeft);

These MyinputField coordinates how do i know them? Can I visualize it on the PDF?

Hi Tom,

From the description of the PXO_InputField method:
Coordinates are in PDF page coordinates, starting with (0,0) at the lower left corner of the page, similar to conventional / Cartesian mathematics (and in contrast to Windows RECT coordinates). The unit is points (72 per inch).

So the bottom left corner of the page is (0,0), and the top right corner for an A4 page (210x297mm) is (595.2755, 841.8897)
For a Letter page - 8.5 x 11 inch the top left will be (612.0 , 792.0)

Regards,
Stefan

Is there a way to optimize the OCR results of a certain font?
I have some numbers that are very frequently are miss translated:

1 instead of 7 (see attachment 1)

Hello Tom,

There are no training tools available for our OCR currently - sorry.

Numbers are indeed quite tricky with some fonts.

Regards,
Stefan
