我在控制台应用程序中使用imageresizer.net从tiff图像中提取页面，但是当tiff包含不同图像类型的页面时，imageresizer提取的内容并不总是代表原始页面。
我正在使用托管API，使用以下代码：
ImageBuilder.Current.Build(sourceImagePath, destinationImagePath, new ResizeSettings("page=[whatever]"));
TIFF图片包含......
我得到的行为是......
我还使用libtiff.net使用this method提取相同的图像，但没有出现相同的错误。
编辑 - 使用此代码使用Wic解码器进行测试：
var settings = new ResizeSettings("decoder=wic&page=" + pageNumber);
Config.Current.Plugins.GetOrInstall<WicDecoderPlugin>();
ImageBuilder.Current.Build(sourceImagePath, destImagePath, settings);
这适用于第1页＆amp; 4（没有更改），但是我得到的对象引用没有设置为对象的实例。＆＃39;第2页和第2页的错误3使用Wic解码器时。
编辑2 - 将未能进入MVC项目的位转换为/resizer.debug：

这是我尝试继承BuilderExtension，覆盖DecodeStream和libtiff.net中的粘合。
这是我的两个测试tiff different size pages＆amp; pages with different colour space。我已针对ImageBuilder v3.2.2编译。
当我使用以下代码在ImageResizer v3.2.2源中使用ConsoleApplication项目时，我遇到了错误。我目前没时间解决这个问题了，所以我想我会把我的进展放在这里以防万一其他人想要进一步解决这个问题。
我的测试代码
我认为在ImageResizer.ImageBuilder.PrepareDestinationBitmap()的{{1}}处失败但参数无效。错误。尺寸是w = 9994，h = 7102并且我怀疑这可能是内存问题 - 但是如果我首先使用s.destBitmap = ...解码tiff并将其作为内存流传递给ImageResizer，则该错误不存在。此外，v3.2.2和v3.2.3都会出现此故障。
DecodeTiffTo32BitBitmap()我的TiffDecoder类：
var Path = @"[whatever]\TiffDecoderTests\";
var c = new Config();
new TiffDecoder().Install(c);
c.BuildImage(Path + "different_page_sizes.TIF", Path + "different_page_sizes-page2-TiffReader.png", "format=png&page=2&decoder=tiffdecoder");

FreeImageDecoder插件现在支持多页TIFF文件，并在内部使用libtiff。这是处理非常复杂/罕见的.TIFF文件的建议方法。
TIFF格式非常复杂且标准化程度很低。大多数库（如GDI +（System.Drawing）和WIC（WPF））只实现标准的一小部分，更不用说事实上的功能和添加。
要获得此级别的.TIFF支持，您需要使用库专用到.TIFF支持，例如libtiff或libtiff.net。
ImageResizer 通过FreeImage和FreeImageDecoder插件与LibTiff集成，但尚未实现多页支持。
没有划桨你不是一条小溪 - 有很多方法可以解决你的困境：
已经有4个解码器的示例实现：ImageBuilder.DecodeStream，PsdReader，WicDecoder，FreeImageDeocoder和PdfRenderer。他们的源代码is included in the download。平均解码器需要不到80行代码。
