Also consult the wiki (https://github.com/fo-dicom/fo-dicom/wiki) for answers to common questions.
@Shuun26 Seems like the tags are queried via some CFind requests. If you need more values, then first you have to add the desired values in the CFindRequest already. And secondly the server has to support those tags, meaning the server has to fill in those values in the response. Most of the servers I know only support a limited number of Tags. So you cannot expect the server to return the value of any tag you are requesting.
@Todilo I assume you are using version 5? on the main github readme page there is a link to api help: https://fo-dicom.github.io/dev/v5/usage/image_rendering.html. And I recomment do take a look at the fo-dicom-samples project. But you are right, documentation is not a strength of fo-dicom. Any help is welcome on that field.
@howff Anonymization is supported as it is defined in DICOM-standard. There is a DicomAnonymizer class that does the anonymization in various profiles. But fo-dicom does not support image recognizion to analyze pixeldata if there is some burnt in text information, or to to modify the pixels of a face to make a person not recognizable in 3d volume of head.

Hello - I'm working in a legacy codebase and am using DicomClient to execute DicomCStoreRequests. I am trying to figure out how to integrate SSL into my client/requests. I just updated to 5.0.2, and haven't been able to find anything related to SSL in the docs. The best reference I've come across is https://stackoverflow.com/a/55413970 however this seems to target an older version. Can someone point me in the right direction? Thanks
Dicom.Log
LogManager.SetImplementation(ConsoleLogManager.Instance); this is ok with console application. What to do for winform app so log can be written in log file
@yadavvirus of yourse you can implement your own logger. All you have to do is to imlement a class that intherits from ILogger and anotherone ineriting from ILogManager which then creates the instances of your ILogger-implementation. Or you can use some ready implementation of Log4Net (a nuget package), but therefore you have to read about how to use and configure log4net.
@gofal Hi, was wondering if anybody could help me with: https://stackoverflow.com/questions/72371819/fo-dicom-start-store-scp-and-then-scu-move-a-study-to-scp
Hi, maybe someone had this issue too: I am trying to assign pixel data in two steps. First a dataset and pixel data is created with
DicomPixelData.Create(dicomVideoFile.Dataset, true); - this file is stored on file system and then read from another process. This process is used to store the pixel data itself. There I am opening the pixel data with DicomPixelData.Create(dicomVideoFile.Dataset, false);because I only want to add the frames itself. When I use a FileByteBuffer object from jpeg files to add frames (JpegBaseline TS, EncapsulatedPixelData) everything works as expected. When I use a MemoryByteBuffer for bitmaps in memory instead (ImplicitVRLittleEndian, OtherWordPixelData) I get following exception: 'Expected pixel data element to have a CompositeByteBuffer.' If I change the call to DicomPixelData.Create(dicomVideoFile.Dataset, true) it works as expected. Why is there a difference?
Hi, I have a user experiencing problems, that I don't see on my pc, see debug messages below. What can cause this?

@WolvesPro I guess you are using the FrameGeometry classes? Then you get this error, if the image does not contain gemoetry data. E.g. there is no pixel spacing tag or so. Usually some secondary capture images (ultrasound or so) do not have pixel spacings. And without pixelspacing you cannot convert the pixels to Millimeter.

Image will be dark completely after resizing, I did resize image as:
using (var renderedImage = image.RenderImage(i))
{
var resizedImage = renderedImage.AsSharedBitmap().Resize(newSize);
resizeImages.Add(resizedImage);
}Then uncompress DCM file because AddGrayScale just works with uncompressed DataSet and Remove PixelData like:
var clonDs = dicomFile.Dataset.Clone(DicomTransferSyntax.ExplicitVRLittleEndian);
if (clonDs.HasPixelData())
clonDs.Remove(DicomTag.PixelData);
var newDS = clonDs.AddImageGrayscale(new GrayscaleMutationDto() { Images = resizeImages.Cast<Image>(), BitsPerPixel = (ushort)bitsAllocated, RowPixelSpacing = newPixelSpacing.Row, ColumnPixelSpacing = newPixelSpacing.Column });
newDS.Save(@"C:\ResizedImage.dcm");but ResizedImage.dcm will be black.
any clue would be appreciated.

I find maybe a bug in fo-dicom in compress file
it maybe lose the pixelDate in multy thread
it is a multy thread do compress file for same file
it maybe lose the pixelDate in multy thread

var transferSyntaxOfDcm = DicomTransferSyntax.JPEG2000Lossless;
transferSyntaxOfDcm = DicomTransferSyntax.JPEGLSLossless;
var dcm = FellowOakDicom.DicomFile.Open(inPath);
var original = dcm.Dataset;
var changed = original.Clone(transferSyntaxOfDcm);
var newdcm = new FellowOakDicom.DicomFile(changed);
newdcm.Save(outPath);
Hello everyone!
I have a question to use DicomImage in UWP application.
I know, that in fo-dicom version 4.0.8 i can add nuget package extension to UWP app and base dicom lib. But how to do it in higher version?
Version:5.0.3.
How to convert IImage to WriteableBitmap, cause if a use method T As<T>(), i had exeception, that i have byte[] array.
I see, that i need to use IImageManager in article her, but maybe somebody have example for this sutiation?
My code example here:
FileOpenPicker openPicker = new FileOpenPicker();
openPicker.ViewMode = PickerViewMode.Thumbnail;
openPicker.SuggestedStartLocation = PickerLocationId.ComputerFolder;
openPicker.FileTypeFilter.Add(".dcm");
StorageFile file = await openPicker.PickSingleFileAsync();
if (file != null)
{
Windows.Storage.Streams.IRandomAccessStream openFile = await file.OpenAsync(FileAccessMode.Read);
Stream sr = new StreamReader(openFile.AsStream()).BaseStream;
FellowOakDicom.DicomFile dicomFile = FellowOakDicom.DicomFile.Open(sr);
FellowOakDicom.Imaging.DicomImage dicomImage = new FellowOakDicom.Imaging.DicomImage(dicomFile.Dataset, 0);
FellowOakDicom.Imaging.IImage imgInterface = dicomImage.RenderImage(currentFrame);
var img1 = dicomImage.RenderImage(0).As<BitmapImage>();
}Thanks everyone for you support!

Why Property [Invert] from [GrayScaleRenderOptions] is private , and there is no way to this became true ? ref: https://github.com/fo-dicom/fo-dicom/blob/5dcac0f30bf9d1442331f934bdb0228ed274dd70/FO-DICOM.Core/Imaging/GrayscaleRenderOptions.cs

I'm using v4.0.8 because this problem used to be isolated to v5.
The two apps are certainly connected to each other, since I get a "connection was actively refused"-error if I de-synchronize their ports; not a "failed to respond"-error.
When I change TransferSyntax by Clone for MG modality , I got
Default transfer is
DCT coefficient out of range error,Default transfer is
1.2.840.10008.1.2.4.70 (JPEG Lossless, Non-Hierarchical, First-Order Prediction (Process 14 [Selection Value 1]): Default Transfer Syntax for Lossless JPEG Image Compression) and I am changing it to DicomTransferSyntax.JPEGProcess2_4, is there a way to avoid this error?
I have implemented C-Store using OnCStoreRequestAsync of IDicomCStoreProvider. But the speed of transfer seem to be very slow. Which makes it unusable at the current state. Is there improvements that I can take. Such as receiving multiple request and saving those file into the server in async way. I have read through this article:
https://www.dicomstandard.org/docs/librariesprovider2/dicomdocuments/wp-cotent/uploads/2018/10/day2_s19-matthijssen-improvedicomnetwoktransfertime.pdf?sfvrsn=3da9e205_2
it talks about Enhanced Family of objects, and A-synchronous Transfer. How to enable A-synchronous Transfer in the fo-dicom
My Current Code:
Receive a single request -> Save the file in FTP server -> Save the information in the Database -> Return the success result.
@rubit0 I'm sorry, but I want to ask you a question because you seem to be using the Unity version of Fo-Dicom. Have you solved the issue related to JPEG or IL2CPP that you mentioned before? I am currently unable to proceed with the work due to the problem with that part. I'd appreciate it if you could tell me.
