# Load document from disk
doc = PdfDocument()
doc. LoadFromFile(inputFile)
# Define a rectangle
rctg = RectangleF (0.0, 0.0, 200.0, 300.0)
pdfPageBase = doc.Pages.get_Item (0)
finder = PdfTextFinder(pdfPageBase)
finder.Options.Parameter = TextFindParameter.none
finder.Options.Area = rctg
# Find text in the rectangle
findouts = finder.FindAllText()
sb=[]
for fragment in findouts:
sb.append (fragment.Text)
sb.append (fragment.TextStates[0].FontName)
sb.append(str(round(fragment.TextStates[0].FontSize,2)))
result ="result.txt"
