To update my situation,
I have added your post-build events to my project properties. But whenever I build, my output directory looks like this
\common
\ClearCanvas.Common.dll
\ClearCanvas.Dicom.dll
\ClearCanvas.Dicom.OffisWrapper.dll
\ClearCanvas.log4net.dll
\log4net.dll
\nunit.framework.dll
\logs
\plugins
\ClearCanvas.Desktop.dll
\ClearCanavs.ImageViewer.dll
\ClearCanvas.ImageViewer.Rendering.BilinearInterpolation.dll
DicomBitmap.exe
DicomBitmap.exe.config
DicomBitmap.pdb
DicomBitmap.vshost
Logging.config
ClearCanvas.Desktop.dll
ClearCanavs.ImageViewer.dll
ClearCanvas.Common.dll
ClearCanvas.Dicom.dll
ClearCanvas.Dicom.OffisWrapper.dll
ClearCanvas.log4net.dll
log4net.dll
nunit.framework.dll
And of course the output is a black file. I also notice the same thing happens on your project if I delete the refernces to ClearCanvas dlls, readd them, then re-build. I am quite lost. I guess what I would like to know is how you added the references

Hi Parmede, A few things: 1) Don't comment out the StartApp line...that has to be there for the plugins to load 2) Make sure you app.config has the "probing privatepath" line (see the app.config in the sample as an example)
3) I noticed you have a number of extra files in the same dir as the exe. In your list, everything from ClearCanvas.Desktop.dll and below should be removed, since they already exist in either the common or plugins directory. You can make sure this doesn't happen by making sure that the Copy Local property on the reference is set to false.

Parmede, I would suggest looking at the developers guide here, and specifically at the section "I want to.. / Deployment / Create a new application". This contains a discussion on the folder organization. Also, the "Getting Started / File Organization / Binary Organization" sections discuss where files are located in the viewer install, which is useful to setup your build properly, to see how the viewer is organized.

Steven and Norman,
Thank you both for your help! The problem was that I hadn't set the Copy Local value of the referenced DLLs to false. Everything has now worked.
Regards,
Parmede |

I load a multi-frame dcm file gotten from IVUS. Render them to bmp files by calling image.DrawToBitmap. But every file has no IVUS image but a line says "Unsupported transfer syntax". I am sure the dcm file is valid. Thanks |

Hi,
The dcm file may well be valid, but the viewer may not support the transfer syntax, which is what that error is saying. Try looking in the log (located in [installdir]\logs) to see what the specific issue is.

Hi Norman
I am pasting exception log here
2009-02-06 13:24:24,828 [1] ERROR - Exception thrown

Thanks for the log. Try doing a dicom dump of the file, then post back here the transfer syntax.

As a note for future reference: The code snippet at the very top of this thread works in versions 1.3 and earlier. In the coming release, the LocalImageSop class has been replaced with a basic ImageSop class for which you pass a LocalSopDataSource object. The resulting modified code for 1.5 and later is the following:
ImageSop sop = new ImageSop(new LocalSopDataSource("MyFile.dcm"));
IPresentationImage image = PresentationImageFactory.Create(sop);
Bitmap bmp = new Bitmap(width, height);
Graphics g = Graphics.FromImage(bmp);
IRenderingSurface surface = image.Renderer.GetRenderingSurface(null, width, height);
surface.ContextId = g.GetHdc();
DrawArgs drawArgs = new DrawArgs(surface, null, DrawMode.Render);
image.OnDraw(drawArgs);
drawArgs = new DrawArgs(surface, null, DrawMode.Refresh);
image.OnDraw(drawArgs);

Hi,
I want to extract a bitmap from a dicom file. I've read some topics about that on your forums. Though i get an error.
Here is the classic sample piece of code
LocalSopDataSource lsdSource = new LocalSopDataSource(dfFile);
//dfFile is a DicomFile that has been loaded.
ImageSop isSop = new ImageSop(lsdSource);
Bitmap bBitmap = null;
IPresentationImage piImage = PresentationImageFactory.Create(isSop.Frames[1]);
bBitmap = piImage.DrawToBitmap(width,height);
bBitmap.Save("d:/test.bmp");
It works fine. However, there is an error message on the output bitmap :
Echec lors du chargement du type de fournisseur (in English : Failed to load provider type ) : ClearCanvas.Common.Configuration.StandardSettingsProvider, ClearCanvas.Common , Version = 1.0.0.0, Culture = neutral, PublicKeyToken = null;
I have a recent version of the framwork : checked out from the svn last week.
I can't solve the problem. Any help would be very appreciated.

Hi, sorry for the late reply. Are you by chance trying to use the CC framework in ASP.NET or as a library from your own application?
Best regards,

I'm using the CC framework as a library from my own application.
I have now more precisions for the problem.
The problem occurs in RenderBase.cs : when Render() calls DrawTextOverlay(), accessing the AnnotationLayout (or AnnotationBoxes, i don't remember very well) property throws an exception (the same as in my last post).
As i couldn't figure out how to solve the problem, I decided to comment DrawTextOverlay() in Render() for the moment.
I hope to find something better. Perhaps I should try with a more recent release of the framework. |

Hi, can you try the same code, but using references to the binaries from our 1.5 SDK and see what happens? It looks like an assembly versioning issue, so I want to try and rule that out.
Thanks,
Stewart |

Hi,
Unfortunately I get the same error with the binaries from the 1.5 SDK
It's likely that I don't reference them the right way or something is wrong in my project structure. I wonder if i could just avoid getting the error message on the image. Is it possible to "catch" the error stream or something similar ?
Thanks for your help |

You could probably just catch the exception, but it troubles me that it doesn't work. If I get a chance later, I'll try to put something together quickly that does the same thing and see if I can reproduce ... right now, I have no other ideas.
Best Regards,
Stewart |

Since I'm not using the CC Framework extensively in my project I don't mind commenting a line so that text overlays don't get drawn on the bitmap. I was just curious about the error. However It doesn't seem that easy to get it solved.
Anyway thanks again for your help,
And thanks a lot for the CC framework; Great Job

I tried it out and everything seems to work ok. Here's the steps I took:
1. Create a new WinForms Application (called it ViewerAsLibrary)
2. Added References to SDK binaries: Common, ImageViewer, Dicom, Desktop
3. Manually copied BilinearInterpolation.dll and logging.config
4. Added a button to the Form that executes the code you provided
Here's the list of files I needed for everything to run properly (all in the same folder, no plugins folder):
BilinearInterpolation.dll
ClearCanvas.Common.dll
ClearCanvas.Desktop.dll
ClearCanvas.Dicom.dll
ClearCanvas.ImageViewer.dll
log4net.dll
Logging.config
ViewerAsLibrary.exe
I loaded an x-ray image and saved it back out as a PNG and it was ok.
Try following exactly the same steps I took and see if it works ... if it doesn't please post back.
Hope this helps,
Stewart |

I followed your steps and it works very well. No error message.
My mistake was not to add logging.config. I know it's in the developper guide but I missed it.
So I tried to add it in my project and now I get another error message on the image telling that the 'FilteredLayoutSettingsXML' property cannot be found.
Thanks for your help |

Hmm, ok. I'm not sure what the problem is, but it seems as though the .NET configuration of your application is in a funny state. I'm going to guess that if you debugged the app, the exception would be thrown from the CC code here:
ImageViewer.Annotations.Dicom.DicomFilteredAnnotationLayoutStoreSettings.FilteredLayoutSettingsXml
Line 34: return ((string)(this["FilteredLayoutSettingsXml"]));
This indicates that your app is unable to load/find that user setting. Is there anything else that is different about your application? Does it use any other libraries or any additional CC plugins? |

Another question: what version(s) of the .NET Framework are installed on your machine? |
