.NET Photoshop Filter Host Library

[null54]

This open source (MS-PL) host library allows any .NET application built with .NET 2.0 or later to run 8bf filters.

https://github.com/0xC0000054/PSFilterHost/

It supports Grayscale and RGB(A) in both 8 and 16 bits per channel.

Processing 16-bit images only works using the System.Windows.Media.Imaging classes in .NET 3.0 or later as GDI+ has limited support for 16-bit images (all GDI+ images are processed as 8-bit RGBA).

It is written in C# using Visual Studio 2010.

Great! But it would be even better to have a DLL version of it that can be accessed from C/C++ and other languages.

If you are using native C, C++ etc the host by DMMD would be a better fit, and it is probably more compatible with newer plugins as it implements the PICA suites.

It would also be possible for someone to write a C++/CLI wrapper for this host so it can be called from native code.

All suites up to Photoshop 4 are implemented with the exception of the Image Services suite, so the library could be used by plugin developers for a standalone 8bf host for example.

Although the Channel Ports suite is only enabled for Luce 2 as some filters do not handle them correctly even under Photoshop.

Added an example host application.

This is a 32-bit and 64-bit host similar to SigmaPi NiGulp.

It uses Windows Imaging Component to load and save the image, it can load any image format that has a codec installed (Camera Raw, WebP etc).

Only BMP, JPEG, GIF, PNG and TIFF are supported for saving.

Version 1.0.0.5 has been released.

Changes:

• Fixed a regression in the scripting code from 1.0.0.4.
• Added a class for the host to set the filter properties (Title, Caption, Ruler units etc).
• Added a .NET 4.0 Client Profile binary.

Added a wiki page describing how to debug filters under the Example Host from Visual C++.

First, awesome idea from your part, and I wish you good luck with it.

Second, thanks @null54 for promote our Photoshop Host SDK http://www.thepluginsite.com/forum/view ... =15&t=3992. Indeed it contain only one ANS C dll which can be called from multiple language programming. Unfortunately we didn't have time for creating Mac version as I promised, but I hope we'll find time in one day.

Thank you and good luck.
