InsertImage Method

Show in webframe







An item in the Data Set.
Image to insert.
The zero-based index at which the image should be inserted.
The type of compression to use.
Photometric constant.
Value that represents the resulting image pixel depth. Possible values are:
Value Meaning
0 Keep the original file's pixel depth (do not convert).
1 to 8 Use the specified bits per pixel in the resulting image.
12 Use 12 bits per pixel in the resulting image.
16 Use 16 bits per pixel in the resulting image.
24 Use 24 bits per pixel in the resulting image.
32 Use 32 bits per pixel in the resulting image.
The quality factor (Q factor) is a number that determines the degree of loss in the compression process. You can set a value from 2 to 255, where 2 is the highest quality and 255 is the most compression.
Flags that control the behavior of this method.
Inserts an image in a Pixel Data element.

Parameters

element
An item in the Data Set.
image
Image to insert.
index
The zero-based index at which the image should be inserted.
compression
The type of compression to use.
photometric
Photometric constant.
bitsPerPixel
Value that represents the resulting image pixel depth. Possible values are:
Value Meaning
0 Keep the original file's pixel depth (do not convert).
1 to 8 Use the specified bits per pixel in the resulting image.
12 Use 12 bits per pixel in the resulting image.
16 Use 16 bits per pixel in the resulting image.
24 Use 24 bits per pixel in the resulting image.
32 Use 32 bits per pixel in the resulting image.
qualityFactor
The quality factor (Q factor) is a number that determines the degree of loss in the compression process. You can set a value from 2 to 255, where 2 is the highest quality and 255 is the most compression.
flags
Flags that control the behavior of this method.
Remarks
Most DICOM files will only have one Data Element of type DicomTag.PixelData. Therefore, in most instances you can set element to null, since the method will automatically insert the image into the only Pixel Data Element in the file. If element is not null, it must point to the Pixel Data Element itself.

If the DICOM file is DicomClassType.BasicDirectory, the file may contain more than one Pixel Data Element. In this case you must specify in element the Pixel Data Element in which to insert the image.

For a table of possible Compression, Photometric, BitsPerPixel, and Quality Factor combinations, refer to Compression Table.

For more options when using the JPEG 2000 compression, refer to Jpeg2000Options.

This method will either insert, delete or update one or more of the following elements:

If the Shared Functional Groups Sequence element or the Per-frame Functional Groups Sequence element is added, an item child element may be added that contains either the (0028,9132) Frame VOI LUT Sequence element or the (0028,9145) Pixel Value Transformation Sequence element.

This method is indifferent to the pixel data restrictions imposed by the various DICOM IOD classes; for example, this method will allow the user to insert a colored image into a "Digital X-Ray Image Storage" Data Set.

This method will always insert a "Number of Frames" (0028, 0008) element and set its value.

The Multi-frame Functional Groups module may have a Shared Functional Groups Sequence item, and/or a Per-frame Functional Groups Sequence item. Either of these items may have a Pixel Value Transformation Sequence (0028,9145) item, or a Frame VOI LUT Sequence (0028,9132) item. The five DICOM_SETIMAGE_MFG flags can be used to add or modify existing information in the Pixel Value Transformation Sequence or the Frame VOI LUT Sequence.

The following flags are used only if the corresponding sequence (Frame VOI LUT Sequence or Pixel Value Transformation Sequence) does not already exist.


In this case, the sequence is placed in the sequence indicated by the flag (Per-frame Functional Groups Sequence or Shared Functional Groups Sequence).
If a Frame VOI LUT Sequence or a Pixel Value Transformation Sequence already exists in a DICOM dataset, the four above flags are ignored, and the sequence is placed in the location where sequences already exist.

For a detailed discussion on Multi-frame Functional Groups see the topic Multi-frame Functional Groups.

Note:
DicomSetImageFlags.MfgVoiLutPerFrame cannot be combined with DicomSetImageFlags.MfgVoiLutShared.
DicomSetImageFlags.MfgModalityLutPerFrame cannot be combined with DicomSetImageFlags.MfgModalityLutShared.
