Reading PSD file format.

Question

I wonder if this is even possible. I have an application that adds a context menu when you right click a file. It all works fine but here is what I'd like to do:

If the file is a PSD then I want the program to extract the image. Is this possible to do without having Photoshop installed?

Basically I want the user to right click and click "image" which would save a .jpg of the file for them.

edit: will be using c# Thanks

Answer 1

Well, there's a PSD plugin for Paint.NET which I think is Open-Source which you might want to take a look at for starters:

Answer 2

The ImageMagick libraries (which provide bindings for C#) also support the PSD format. They might be easier to get started with than getting into the Paint.NET code and also come with a quite free (BSD-like) license.

A simple sample (found at http://midimick.com/magicknet/magickDoc.html) using MagickNet would look like this:

using System;

static void Main(string[] args)
{
    MagickNet.Magick.Init();
    MagicNet.Image img = new MagicNet.Image("file.psd");
    img.Resize(System.Drawing.Size(100,100));
    img.Write("newFile.png");
    MagickNet.Magick.Term();
}

Note: MagickNet has moved to http://www.codeproject.com/KB/dotnet/ImageMagick_in_VBNET.aspx

Answer 3

FastStone does this pretty efficiently. They do not have their libraries availaible, but I guess you can contact them and see if they can help.

Check out their website: http://www.faststone.org/download.htm

Answer 4

This guy do it easier:

With a C# library and a sample project.

I've tried with PS2 files and works ok.

Answer 5

I have written a PSD parser which extracts raster format layers from all versions of PSD and PSB. http://www.telegraphics.com.au/svn/psdparse/trunk

Answer 6

You can use .NET imaging SDK from Aurigma to extract raster and text layers from PSD files.
