问题 How can I check what version of Windows Imaging Component is installed on a Windows machine? I suspect the Windows 2008 Servers used in Azure do not have the same version that I have on my Windows 7 development machine. I just want to verify that as I need the latest TIFF codec. 回答1: Will not make a definite statement, but I think that the WIC on the Windows Azure is the same what you have on your Windows 7. Just be aware that there are 2 OS families in Windows Azure. OS Family 1.x is using

问题 I'm trying to write a routine that will save a WPF BitmapSource as a JPEG encoded TIFF using LibTiff.net. Using the examples provided with LibTiff I came up with the following: private void SaveJpegTiff(BitmapSource source, string filename) { if (source.Format != PixelFormats.Rgb24) source = new FormatConvertedBitmap(source, PixelFormats.Rgb24, null, 0); using (Tiff tiff = Tiff.Open(filename, "w")) { tiff.SetField(TiffTag.IMAGEWIDTH, source.PixelWidth); tiff.SetField(TiffTag.IMAGELENGTH,

How can I get the StripOffsets tag to stay the same when using the LibTiff.Net 2.3 library?

问题 I have an original image that has a tag StripOffsets = 768. When I edit the image in memory and then write it back to a file I try to specifically set the StripOffsets tag manually to the same value of the original which is 768 (using the following method). //Set the height for the page output.SetField(TiffTag.ROWSPERSTRIP, ttPage[i].Height); //Set the offset for the page output.SetField(TiffTag.STRIPOFFSETS, ttPage[i].StripOffset); For some reason the end results is StripOffsets = 8. Why

问题 I am trying to use libtiff.net to read elevation data from a GeoTIFF file. So far I have mostly just been able to read metadata from the file using the example at libtiff.net's webpage. But howto read elevation data I do not understand... I tried first reading with Tiff.ReadScanline() as described here but the file I have seems to be stored differently (probably in tiles if I understand it correctly) Here is the metadata (as far as I have been able to read) (the tiff file is from the danish

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago . I need to convert a TIFF to JPEG using .NET. I have already done this succesfully using Windows 7 with a simple Bitmap.Save() . But it seems that this doesn't work on Windows XP (Windows 7 has more complete support for TIFF images). I saw that there is a .NET library called

LibTiff.NET ReadDirectory is giving System.ObjectDisposedException Only During Unit Tests

问题 Edit: FYI for future readers, this issue has been fixed as of version 2.3.606.0 of BitMiracle's LibTiff.NET.

问题 First I want to thank Bitmiracle for this great lib. Even while creating very big files, the memory footprint is very low. A few days ago I ran into a problem where I wanted to create a tiff file bigger than 4GB. I created the tiled tiff file successfully, but it seems that the color of the tiles created beyond 4GB are somehow inverted. Here the code relevant code: Usage: WriteTiledTiff("bigtiff.tiff",BitmapSourceFromBrush(new RadialGradientBrush(Colors.Aqua,Colors.Red), 256)); Methods:
