Load a DICOM image from local storage in C#

DICOM

To load a DICOM image from local storage, use the CreateGdPictureImageFromFile method of the GdPictureImaging class.

This method returns a non-zero GdPicture image identifier (imageID) on success. If it fails, it returns 0 — use GetStat() to get the failure reason.

DICOM files can contain multiple pages/frames. You can use:

When you no longer need the image resource, release it with ReleaseGdPictureImage method.

To load a DICOM image from local storage, use the following code:

using GdPicture14;
using System;


using GdPictureImaging gdpictureImaging = new GdPictureImaging();


int imageID = gdpictureImaging.CreateGdPictureImageFromFile(@"C:\temp\source.dcm", false);
if (imageID == 0)
{
    Console.WriteLine($"Load failed: {gdpictureImaging.GetStat()}");
    return;
}


int pageCount = gdpictureImaging.DicomGetPageCount(imageID);
if (pageCount > 1)
{
    GdPictureStatus status = gdpictureImaging.DicomSelectPage(imageID, 1);
    if (status != GdPictureStatus.OK)
    {
        Console.WriteLine($"DicomSelectPage failed: {status}");
        gdpictureImaging.ReleaseGdPictureImage(imageID);
        return;
    }
}


GdPictureStatus saveStatus = gdpictureImaging.SaveAsPNG(imageID, @"C:\temp\output.png");
if (saveStatus != GdPictureStatus.OK)
{
    Console.WriteLine($"SaveAsPNG failed: {saveStatus}");
}


gdpictureImaging.ReleaseGdPictureImage(imageID);
