Implementation of a JPEG plugin for the dcmimgle/dcmimage library.
◆ getLibraryVersionString()
| static OFString DiJPEGPlugin::getLibraryVersionString |
( |
| ) |
|
|
static |
get version information of the TIFF library.
Typical output format: "IJG, Version 6b 27-Mar-1998 (modified)"
- Returns
- name and version number of the TIFF library
◆ outputMessage()
| void DiJPEGPlugin::outputMessage |
( |
void * | arg | ) |
const |
callback function used to report IJG warning messages and the like.
Should not be called by user code directly.
- Parameters
-
| arg | opaque pointer to JPEG compress structure |
◆ setQuality()
| void DiJPEGPlugin::setQuality |
( |
const unsigned int | quality | ) |
|
set quality value for JPEG compression
- Parameters
-
| quality | quality value (0..100, in percent) |
◆ setSampling()
set (sub) sampling for JPEG compression.
Only used for color images. ESS_444 means no sub-sampling, ESS_422 horizontal subsampling of chroma components and ESS_422 horizontal and vertical subsampling of chroma components.
- Parameters
-
| sampling | sampling (valid values: ESS_444, ESS_422 or ESS_411) |
◆ write()
| virtual int DiJPEGPlugin::write |
( |
DiImage * | image, |
|
|
FILE * | stream, |
|
|
const unsigned long | frame = 0 ) const |
|
virtual |
write given image to a file stream (JPEG format)
- Parameters
-
| image | pointer to DICOM image object to be written |
| stream | stream to which the image is written (open in binary mode!) |
| frame | index of frame used for output (default: first frame = 0) |
- Returns
- true if successful, false otherwise
