Old-style Windows Metafiles
(WMF) exported by Surfer (or copied to the clipboard) are now higher resolution
and look better.
Exporting in bitmap format now allows setting of dithering and quantization
options.
DXF Export will now only map a Surfer color to a DXF gray color if the Surfer
color is itself a gray color. This results in better overall mapping of Surfer
to DXF colors.
Fixed a problem where scrolling rotated bitmaps produced an "Internal
inconsistency detected" error.
The vector pattern editor now accepts lines containing more than two vertices.
Worksheet now uses correct delimiters when saving to user-defined ASCII formats.
Bitmap fill patterns will now appear the same on printers and in metafiles
as they do on the screen.
Specifying a bitmap fill pattern in the Contour Properties dialog box causes
the text in the Levels table to take on the color of the fill (fixed).
A bug was introduced in version 8.02 that caused the gridding search neighborhood
to contain more or less points than it should have. This resulted in subtle
accuracy errors for any gridding method using a search. This has been corrected.
Surfer 8.02 (Oct 1, 2002)
Creating a periodogram
from some unusual grids can cause a crash (fixed).
Fixed an internal error when calculating the kriging standard deviation grid.
Fixed a problem with post map label lines being drawn incorrectly.
Fixed an issue with slow save times in the worksheet.
Bitmaps sometimes draw upside down (fixed).
Two small memory leaks were fixed in the bitmap export code.
Fixed some problems with the SYLK import/export to make it faster when there
are a lot of cell formats present.
Exporting an "empty" plot to a GSB or MIF file resulted in an invalid
file (fixed).
Fixed an internal error when saving the worksheet to SLK format.
Fixed a problem reading some LVL files that resulted in a "Bad format"
message.
The EMF import filter reported an "Internal Inconsistency" error
with some metafiles (fixed).
Metafiles sometimes lose the right and bottom edges when drawn (fixed).
Updated the symbols.srf example to use the latest symbol sets.
Fixed an internal error message during gridding. This was caused by an out
of memory condition that was not correctly reported due to a Microsoft bug.
Increased the precision of polynomial regression. This allows a few marginal
cases with large orders to proceed to completion.
Worked around several printer issues related to printing bitmaps. Most of
these problems were related to poorly written HP printer drivers that do not
implement the required functionality or report incorrect information to the
program.
Fixed a bug in the Inverse Distance Gridding algorithm that resulted in incorrect
grids if there are no faults and the power is not equal to 2.0.
Some metafiles produced by Surfer could not be read by non-Golden Software
apps due to incorrect information in the metafile header (fixed).
Modified the base map font scaling to NOT scale text when the base map is
scaled. This allows the font size displayed in the base map dialog to accurately
reflect the physical size in the drawing, and emulates the Surfer 7 behavior.
A similar modification was made for symbols in base maps.
Fixed a minor bug that caused the Y axis title on variograms from being updated
when the estimator was changed.
Fixed a floating point exception that was triggered by setting the in-line
label font height to 0.0.
Added an error message if an attempt is made to digitize a map with perspective
projection. This is no longer allowed due to accuracy issues. Change the map
to orthographic projection before digitizing.
The MIF import filter has been improved to handle rotated text better.
Line width in surface plots was not correct at various zoom levels or when
printed (fixed).
Version 8.01 (May 9, 2002)
Fixed a redraw issue caused
by showing/hiding the rulers
Clipped image maps were extrapolating colors beyond the grid limits (fixed)
Includes the latest version of Sax BASIC (change list not available)
Disabled F1 Help in Internet Update
Added the requested size of the bitmap to the error message when a bitmap
cannot be created
Disabled unused ID fields in some output option dialogs (like SHP)
Resolved conflicting hotkeys in the Map menu
Fixed an issue when reading CSV files (blanks were interpreted as delimiters)
Added the XLS extension to the "Files of Type" list in the File
Open dialog
Fixed a bug that resulted in a very long grid report when breaklines were
used
Improved error messages when bitmap output fails
Fixed an internal error that resulted from vector pattern names longer than
29 characters.
Fixed an issue with the Scripter help window always being on top
Added a better error message when a standard deviation grid is completelyblanked
Help | Feedback | Problem Report now does a better job distinguishing the
OS and version number
The worksheet has been modified to correctly read BLN files with space delimiters
Surfer 8 now closes unclosed polygons in BLN files
Now shipping and installing MSVCP60.DLL
Fixed an issue with class limits when the maximum data value is exactly 0.0
The WMF import filter has been altered to work around a problem with bad PolyPolygon
data in some metafiles
Worked around a Microsoft bug that failed to output carriage returns in reports
saved in TXT format
Changing the worksheet columns in the Grid Data dialog resulted in several
errors when the columns contained data in disjoint rows (fixed)
Fixed an issue that prevented validation of the serial information when executed
by a non-Administrator account
Worked around an issue when printing custom bitmap patterns on Postscript
printers
Fixed a bug that caused all 3D OpenGL text to be output in bold
Modified the printer output code to reduce the output file size and increase
the speed. Most of these issues were related to true-color bitmaps
Surfer was ignoring the nugget effect when kriging (fixed)
The GSB export filter has been fixed (it would occasionally write an invalid
file).
Dithering has been improved when exporting to bitmap formats.
The SHP import filter now correctly recognizes "No Data" values.
Image map resolution has been improved when exporting to bitmap formats. See
the new MaxImageMapRes setting below for additional information.
Worksheet Cell Properties dialog now displays the proper cell type when an
entire column is selected.
Surfer no longer opens two copies of worksheet files when the data files are
double clicked from the shell.
