[alt.graphics.pixutils] NCSA's image plot

jkchan@lynx.cat.syr.edu (J. K. Chan) (03/18/91)

Anyone knows how NCSA (the graphics tool developed by
the people in U. of Illinois) Image or Datascope displays their image
files on Mac?  The speed of their display is fast.  It would be nice if we
can get the source codes of the corresponding graphic subroutines.
We are using Think C 4.0 object library.  Any comment on displaying
image files on Mac screens is appreciated.  Please reply by email to the
above address.  Thanks in advance.

Elementary.  We use the MacOS CopyBits.  There are some tricks about
aligning the bitmap with byte and word boundaries to speed things up,
but I dont know that we bothered with that.

You can get the source code by anonymous ftp to ftp.ncsa.uiuc.edu, same
place as the binaries.
