I would like to create a pdf file manually without using any third-party libraries. I need to create a sample invoice format which will have some text, a table and an image with raw pdf objects. I looked into few pages but there is no proper data provided and suggesting using third party libs. It will be really helpful if is some information.

I gone through some sections in specification. I am able to create pdf with small text using provided example. Need some help in adding a table and an image into the pdf. In the pdf examples encoding is used so I am not able to understand the table creation. I need raw objects format without any encoding in the file.
Programming PDF in a console is easy, but first you need to write your PDF Header, so for a Single Page that should be simple enough in MS NotePad IDE and to Compile simply press Ctrl+S while using a real time view alongside.
For your starter I would use a CMD to simply write the basics then add logos and Images later as they are binary and need more maths, such as using DIR to get their filesize. HOWEVER I am going to say that to make a "Basic" File.pdf acceptable for clients, either needs a parse through Printing or other PDF Lib to tidy up to a compliant level (any single CLI.exe may do).
PDF is mainly XY co-ordinates (like on a graph) so 30 550 m 565 550 l says go to start at 30,550 then moving to 565,550 draw a line the final S is the command to strike as a stroke so each line is defined exactly where needed from origin at lower left in the pages units (normally at points as 1/72" but accepts decimals) a graph paper sheet with units at say 10/72 " can help draft a template.
