News of the Data Plotting Software DISLIN
22-Mai-2001
DISLIN version 7.5 is released with the following new features:
- PDF files can be created by DISLIN with the keyword 'PDF' in the
routine METAFL. DISLIN supports compressed and non compressed PDF
files. The new DISLIN routine PDFMOD selects the compression mode.
PostScript fonts can be used for PDF files in the same way as for
PostScript files.
- The routine TRIANG calculates the Delaunay triangulation of an
arbitrary collection of points in the plane. The Delaunay
triangulation can directly be used to display surfaces and contours
of irregularily distributed data points. The corresponding routines
are CRVTRI, SURTRI and CONTRI.
- The routine CICR3P calculates circles specified by three points.
- The keyword 'DELAY' is added to the keyword list of the routine
WINMOD for blocking the graphics window in DISFIN for a short time.
The delay time can be modified with the routine WINOPT.
- Hardware fonts for widgets can be defined with the new routine
SWGFNT (CFONT, NSIZE) where CFONT can contain a Windows or X11
font. NSIZE specifies the font size in points.
- The routine SWGSTP (STEP) defines a step value for scale widgets.
Callback routines are now possible for scale widgets.
- The colours of shaded contour lines can be defined directly with
the routine CONCLR.
- A temperature colour table is added to the list of colour tables.
It can be defined with the parameter 'TEMP' in the routine SETVLT.
- The possible length of strings in the routines NAME and TITLIN
is increased from 60 to 132 characters.
10-November-2000
DISLIN version 7.4 is released with the following new features:
- TeX instructions for mathematical formulas can be used in all
text plotting routines if TeX mode is enabled with the routine
TEXMOD. The routine TEXOPT sets additional parameters for TeX mode.
- The keyword 'PPM' can be used in METAFL for creating PPM files.
The PPM (Portable Pixmap) format is added to DISLIN for creating
MPEG movies with the third party program mpeg_encode.
- The routine SURISO plots isosurfaces of the form f(x,y,z) = constant.
The algorithm used in SURISO is based on the Marching Cubes method.
Flat or smooth shading can be used with SURISO and lighting may be
enabled.
- Lighting can be enabled for shaded surfaces with the routine
LIGHT. The routines LITPOS, LITMOD, LITOPT and MATOPT modify
lighting parameters. The routine GETLIT calculates colour values
for given points and corresponding normals.
- All shaded surfaces can have additional mesh lines if mesh lines are
enabled with the routine SURMSH. With the keyword 'ONLY' in SURMSH,
the shading of surfaces is suppressed and only mesh lines are
plotted. Especially, the routine SURSHD can be used instead of
SURFCE for plotting mesh grids with an alternate hidden-line
algorithm.
- The routine SPHE3D plots a sphere where lighting can be enabled.
- The keyword 'DMONTH' is added to the routines TICMOD and LABMOD
for plotting date ticks and labels for every second month. The
keyword 'TINY' is added to LABMOD for plotting only the first
character of month labels.
- The routine GETSCR returns the screen size in pixels.
- The routine GETDSP returns now the values 'XWIN', 'WIND' and 'NONE'
for X11, Windows and other displays.
- The items of list widgets can be modified with the new keyword
'LIST' in SWGATT.
