The lazarus TJPEGImage is in lazjpeg.pas
|
|
|
|
It uses the pasjpeg and fpimage libs provided by FreePascal. See there for in
|
|
more detailed jpeg handling.

JPEG (pronounced "jay-peg") is a standardized familly of algorithms for
|
|
compression of continous tone still images. Most JPEG processes are lossy,
|
|
the output image is not exactly identical to the input image. However, on
|
|
typical photographic images, very good compression levels can be obtained
|
|
with no visible change, and remarkably high compression levels are possible
|
|
if you can tolerate a low-quality image. The Independent JPEG Group (IJG) has
|
|
created a free, portable C library for JPEG compression and decompression of
|
|
JPEG images which has been ported to FreePascal.
