Bitmap(Size,PixelFormat,Matrix,Int32) Method

In This Topic

Creates a new Bitmap object, in the chosen format representing the appearance of a DicomImage

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Function Bitmap( _
   ByVal Size As System.Drawing.Size, _
   ByVal Format As System.Drawing.Imaging.PixelFormat, _
   ByVal Matrix As System.Drawing.Drawing2D.Matrix, _
   ByVal frame As System.Integer _
) As System.Drawing.Bitmap

public System.Drawing.Bitmap Bitmap( 
   System.Drawing.Size Size,
   System.Drawing.Imaging.PixelFormat Format,
   System.Drawing.Drawing2D.Matrix Matrix,
   System.int frame
)

Parameters

Size: The size of the image to generate
Format: The requested format
Matrix: The Matrix to apply to convert from DICOM coordinates to Bitmap coordinates
frame: The frame number to use. This is 1-index, i.e. first frame is 1 not 0

Return Value

A Bitmap object

Remarks

Only some formats are allowed by Windows - only those supported by System.Drawing.Graphics.FromImage(System.Drawing.Image)

Example

DicomImage image = new DicomImage("path_to_your_dicom_image");
                    
int width = 512;
int height = 512;
Size size = new Size(width, height);
 
Matrix matrix = new Matrix();
matrix.Scale(1.5f, 1.5f); // Scale 1.5x in both width and height
                    
// Basic bitmap call with predefined size to retrieve 10th frame of a multiframe image
var bitmap = image.Bitmap(size, PixelFormat.Format24bppRgb, new Matrix(), 10);
                    
// A Matrix applied 
var bitmap = image.Bitmap(size, PixelFormat.Format24bppRgb, matrix, 1);
                    
var originalWidth = Convert.ToInt16(image.DataSet[Keyword.Columns].Value);
var originalHeight = Convert.ToInt16(image.DataSet[Keyword.Rows].Value);
Size originalSize = new Size(originalWidth, originalHeight);
                    
// Original Image Size
var bitmap = image.Bitmap(originalSize, PixelFormat.Format24bppRgb, new Matrix(), 1);
       
bitmap.Save("path_to_save_location_image.bmp");
