| virtual int DiJPEGPlugin::write | ( | DiImage * | image, | |
| FILE * | stream, | |||
| const unsigned long | frame = 0 | |||
| ) | const [virtual] |
write given image to a file stream (JPEG format)
| 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) |
Implements DiPluginFormat.
| void DiJPEGPlugin::setQuality | ( | const unsigned int | quality | ) |
set quality value for JPEG compression
| quality | quality value (0..100, in percent) |
| void DiJPEGPlugin::setSampling | ( | const E_SubSampling | sampling | ) |
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.
| sampling | sampling (valid values: ESS_444, ESS_422 or ESS_411) |
| 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.
| arg | opaque pointer to JPEG compress structure |
| static OFString DiJPEGPlugin::getLibraryVersionString | ( | ) | [static] |
get version information of the TIFF library.
Typical output format: "IJG, Version 6b 27-Mar-1998 (modified)"
