• File.ReadAllText() method: Reads the text in the text file into a string object.
• PdfDocument.Pages.Add() method: Adds a page to a PDF document.
• PdfTextWidget.Draw() method: Draws the text widget at a specified location on the page.

The following are the detailed steps to convert TXT to PDF in Python:

• Read text from the TXT file using File.ReadAllText() method.
• Create a PdfDocument instance and add a page to the PDF file.
• Create a PDF font and brush objects.
• Set the text format and layout.
• Create a PdfTextWidget object to hold the text content.
• Draw the text widget at a specified location on the PDF page using PdfTextWidget.Draw() method.
• Save the PDF file using PdfDocument.SaveToFile() method.

from spire.pdf.common import *
from spire.pdf import *

def ReadFromTxt(fname: str) -> str:
    with open(fname, 'r') as f:
        text = f.read()
    return text

inputFile = "input.txt"
outputFile = "TextToPdf.pdf"

# Get text from the txt file
text = ReadFromTxt(inputFile)

# Create a PdfDocument instance
pdf = PdfDocument()

# Add a page
page = pdf.Pages.Add()

# Create a PDF font and PDF brush
font = PdfFont(PdfFontFamily.TimesRoman, 11.0)
brush = PdfBrushes.get_Black()

# Set the text alignment and line spacing
strformat = PdfStringFormat()
strformat.LineSpacing = 10.0
strformat.Alignment = PdfTextAlignment.Justify

# Set the text layout 
textLayout = PdfTextLayout()
textLayout.Break = PdfLayoutBreakType.FitPage
textLayout.Layout = PdfLayoutType.Paginate

# Create a PdfTextWidget instance to hold the text content
textWidget = PdfTextWidget(text, font, brush)

# Set the text format
textWidget.StringFormat = strformat

# Draw the text at the specified location on the page
bounds = RectangleF(PointF(0.0, 20.0), page.Canvas.ClientSize)
textWidget.Draw(page, bounds, textLayout)

# Save the result file
pdf.SaveToFile(outputFile, FileFormat.PDF)
pdf.Close()
