Parsing a .pdn


Recommended Posts

Hi Everyone,

 

I am an indie game developer working on a 2D game for my thesis, which will require a custom engine. I really enjoy Paint.NET, so I wanted to know if there was a way I could use it as a kind of world layout tool. I want to use layers to create a level of the game world in Paint.NET, then access the .pdn to parse the file into something my game can later load at run-time.

 

In short, is there a way for me to parse a .pdn file to find out image and layer information? If so, what information would I find available?

 

I am using Python (but can use C) if that matters.

 

Thanks!

I hate to disappoint, but I don't see that happening. I could be wrong. You may want to wait to hear it from the horse's mouth.

 

As far as I know....When Rick created the .pdn, he didn't reinvent the wheel. He simple let the .Net Framework handle certain things. I think it's very unlikely that you'll be able to reverse-engineer it, without also reverse-engineering parts of .Net  (or using Mono as a dependency). Even third-party .pdn viewers, like IrfanView, are only able to read the embedded png preview and not the different layers.

 

It's been years since I listened to this, but from what I remember, Rick goes into some of the minor details of the .pdn format.... http://www.dotnetrocks.com/default.aspx?showNum=229

 

Hope that helps.

 

TL;DR... Make your life easier and use a different format for your game.

You are wrong. The Irfanview plugin can read and show all individual layers and create the composite image in full resolution with alpha channel.

 

You are right. The Irfanview plugin uses an embedded deserializer (written in C) to extract layer and metadata informations.

Well what do you know. I stand corrected. I didn't remember it being able to show individual layers. I haven't used it in a number of years ;)
