Hi

Is there a way to create a text overlay on a PDF from the Microsoft Vision OCR API response in C#? Second to that, what would be the best approach in changing the font size to match the exact bounding boxes?

I have attached a sample form - Sample Document.pdf (643.4 KB). Here is the sample bounding box JSON response from the Microsoft Vision OCR API:

{
“lines”: [
{
“boundingBox”: [
79,
83,
853,
83,
853,
130,
79,
130
],
“text”: “Employment Application”
}
]
}

The bounding box definition is as follows. It show the bounding box corner position in pixels.

“boundingBox”:[
left,
top,
right,
top,
bottom,
left,
bottom,
]

The expected result should be something like this with a text overlay on the document:Result.jpg (150.6 KB)
