DICOM Format (DIC)

DICOM (DIC) files are commonly used in medical images.

LEADTOOLS reads a broad range of DICOM formats, converting them to LEAD-supported bits-per-pixel as necessary. Read Support is provided in all toolkits. Full support for this file format is available in the Medical Imaging toolkits.

LEADTOOLS writes DICOM files in the LEAD-supported bits-per-pixel. DICOM files can contain many comment fields of various types. Use the L_ReadFileComment function to read comments in an existing file. Before writing a file, use the L_SetComment function to create an array of comments to be saved in the file. Use the L_DeleteComment function to delete a comment field from a file.

You can read DICOM files as follows:

You can write DICOM files as 8, 12, or 16-bit grayscale, 8-bit palettized color, or 24-bit RGB color (8 bits per plane).

The file constants associated with this file format are:
