如何使用LibTiff c＃禁用控制台上显示的警告消息＃

Question

I need help to stop annoying warnings displayed on my console .

I'm getting the following warnings using an application that detects corrupted images . The application works as expected but these messages appear.

ReadDirectory: Warning, C:\\find corrupted images\\a.TIF: unknown field with tag 50701 (0xc60d) encountered fillStrip: C:\\find corrupted images\\b.TIF: Read error at scanlin e -1; got 7115 bytes, expected 10130 ReadDirectory: Warning, C:\\find corrupted images\\c: unknown field wit h tag 33885 (0x845d) encountered ReadDirectory: Warning, C:\\find corrupted images\\d: unknown field wit h tag 50701 (0xc60d) encountered ReadDirectory: Warning, C:\\find corrupted images\\e:

tif: unknown field with tag 50701 (0xc60d) encountered ReadDirectory: Warning, SamplesPerPixel tag is missing, assuming correct Samples PerPixel value is 1

Any ideas how to stop these messages appearing ?

Thanks in advance

You should provide your own error handler to the library if you don't want warnings to appear in console.

Start by creating class which inherits from TiffErrorHandler and overloads WarningHandler and WarningHandlerEx methods. Basically, you could do nothing in these methods.

Then set an instance of you class as the error handler for the library with SetErrorHandler method. The method is static and you can set error handler before opening an image.
