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. LEADTOOLS writes DICOM files in the LEAD-supported bits-per-pixel. DICOM files can contain many comment fields of varioius types. Use the LFile::ReadComment function to read comments in an existing file. Before writing a file, call the LFileSettings::SetComment function to create an array of comments to be saved in the file.
You can read DICOM files as follows:
Grayscale files in the 1- to 16-bit range are loaded as they are in the original file.
Palettized color files in the 1- to 16-bit range are converted to 8-bit palettized or 24-bit unpalettized. By default, they are converted to 24-bit only if the palette contains more than 256 colors.
Unpalettized color files (RGB, ARGB, or CMYK) with 1 to 16 bits per plane are converted to 24-bit RGB.
Read multipage DICOM files by setting the page number in LOADFILEOPTION.
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:
