Import an image from a file with default attributes
| Visual Basic |
|---|
Public Sub FileImport( _ ByVal FileName As String, _ ByVal Type As String, _ Optional ByVal Information As Variant _ ) |
Like the Paste method, this method modifies only the minimum number of attributes necessary to ensure consistency of the image. In order to produce a valid DICOM SOP instance, many other attributes (depending on the SOP class) must be added.
If Type is omitted or zero length, it is assumed to equal the extension of the filename for “FileImport”, but must be specified for the other forms.
Only JPEG, BMP/DIB, AVI and (experimentally) MPEG formats are supported directly, but other formats may be supported via extension DLLs.
The following applies to JPEG file import:
The JPEG data is imported directly, and may either be stored or transmitted unchanged as a JPEG encapsulated SOP instance (1.2.840.10008.1.2.4.50), or automatically decompressed if necessary.
The Type parameter must be JPEG or JPG
The Information parameter is not used.
The following applies to DIB/BMP file import:
Data must be uncompressed.
If a BMP file header is present, this is detected automatically.
The Type parameter must be DIB or BMP
The Information parameter is not used.
The following applies to AVI file import:
The Type parameter must be AVI
The Information parameter is not used.
A multi-frame DICOM image is generated.
The following applies to MPEG file import:
The Type parameter must be MPG
The Information parameter is not used.
An MPEG-2 encoded DICOM image is generated.
FFMpeg implementation supports other popular video formats as well.
