ReportLab :
---Open source python libraries for pdf creation.
---ReportLab is fast ,flexible, and fully cross platform
---The ReportLab library directly creates PDF based on your graphics commands
Installing syntax:
---sudo apt-get install python-pip
---pip install reportlab
The pdfgen package is the lowest level interface for generating PDF documents.
A pdfgen program is essentially a sequence of instructions for "painting" a document onto a sequence of pages
The interface object which provides the painting operations is the pdfgen canvas.
The canvas should be thought of as a sheet of white paper with points on the sheet identified using Cartesian (X,Y) coordinates
--default have the (0,0) origin point at the lower bottom left corner of the page.
A simple example program that uses a canvas follows.
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvasc = canvas.Canvas("form.pdf", pagesize=letter)
c.setFont('Helvetica', 12)
c.drawString(30,750,'OFFICIAL COMMUNIQUE')
c.drawString(30,735,'OF ACME INDUSTRIES')
c.drawString(500,750,"12/12/2010")
c.line(480,747,580,747)
c.drawString(275,725,'AMOUNT OWED:')
c.drawString(500,725,"$1,000.00")
c.line(378,723,580,723)
c.drawString(30,703,'RECEIVED BY:')
c.line(120,700,580,700)
c.drawString(120,703,"JOHN DOE")
c.save()
