Is there a library in C# that will allow me to read the layers in a photoshop file (PSD) and extract them as transparent images (PNG)?

Photoshop has a batch command that will extract all layers in individual files but there is no choice of transparent PNGs. My goal is to create a small utility program that will create combinations of layers as you like (for example think of creating a card deck).

There's a nice article on CodeProject which might be helpful. And here's a thread on SO discussing PSD file format parsing with C#.

我在任何地方都找不到太多，但这就是我最终这样做的方式。

using Photoshop;

Photoshop.PsdFile psd = new Photoshop.PsdFile();
psd.Load(pingTextsPsd);

for (int j = 0; j < psd.Layers.Count; j++)
            {
                System.Drawing.Image myPsdImage = ImageDecoder.DecodeImage(psd.Layers[j]);

                myPsdImage.Save(pingsOutputPath + psd.Layers[j].Name + ".png");

            }

我必须下载 Frank Blumenberg 先生所做的 cs 文件（基于 Jonas Beckeman 的 Endogine 引擎），因为获得paintdotnet dll 本身还不够。

我相信正是在这里我得到了cs文件。

这应该允许您获得图层..

:-)

这似乎也适用于 CS6 文件。

您可以使用 Photoshop COM 做到这一点。

ImagicMagick（在另一篇 SO 文章中提到）确实允许单独提取层。见：http ://www.rubblewebs.co.uk/imagemagick/psd.php

您可以使用命令行工具自己尝试：

convert boots.psd[0] -thumbnail 340x340 boots_png.png

I found a code sample that does this in Java.

"Supports uncompressed or RLE-compressed RGB files only"

Also supports only older PSD versions :

"Does not support additional features in PS versions higher than 3.0"

Also ImageMagick handles PSD and has interfaces to many languages :

"Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), JMagick (Java), L-Magick (Lisp), NMagick (Neko/Haxe), MagickNet (.NET), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (PHP), IMagick (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick (Tcl/TK)"

如果您没有安装 Photoshop，那么您可能需要查看http://frankblumenberg.de/doku/doku.php?id=paintnet:psdplugin上的代码以获取更多加载 PSD 文件的示例代码。

不幸的是，我不知道现有的 PNG 库可以满足您的要求，但用于 PNG 文件操作的规范库代码位于http://www.libpng.org/pub/png/。
