OpenGL Extension Viewer

What's new in this version:

Surfer 23.4
Improvements:
- Updated information in the About dialog
- Legend: do not stretch text/symbol/line/fill contents when stretching legend (only adjust the margin property), and only stretch proportionally
- Profile: update automatically when replacing the source grid file

Fixed:
- Assign NoData: inconsistent NoData assignment around the boundary line
- Automation: server exception when loading IMG file for relief map and Surfer became unusable
- Automation: xMapPerPU and yMapPerPU not reporting correctly after scale transforms were applied
- Bring to Front and Send to Back: Contents window needed a refresh
- Color Relief: Data limits did not update when changing from Reflectance to Color only after reload grid
- Colormap Editor: Data Value box did not update when set to a negative value and Apply was clicked
- Could create a Variogram inside a base layer
- Crash when adding empty base layer
- Crash when closing Surfer after file not fully loaded
- File | Open: some SRF files took a long time to open in v23 due to invisible color scale attached to a grid layer with a large data range
- Grid From Contours: some contours with ZLEVEL or Z Coordinate information were ignored
- Internal Error after assigning NoData to a grid using a DXF file containing polylines with collinear data (polygonutility.cpp)
- Internal Error when creating Worksheet window
- Map Wizard: the 'Entire grid was blanked' error appeared too early and prevented gridding
- Moving with arrows sometimes moved the object always left (or always right)
- The "Lock Position" feature still allowed a node to be moved when nudging with the arrow keys


Surfer 23.3
Improvements:
- Common graphic files: add GML extension
- Update EULA in Surfer for subscription licensing

Fixed:
- 3D View: default camera is far away when Map and layer have different coordinate systems
- 3D View: Export 3D: some surfaces export with the axis labels in the wrong location
- 3D View: Export to VRML: textured surfaces with blanked areas can lose surface color
- 3D View: Surfaces: shading resolution doesn't work anymore
- AutoSave: failure during recovery prevents Surfer from running
- Base (vector) layer: changing Map coordinate system reverses image
- Base Map: Ellipse, Rounded Rectangle, and Rectangle did not name properly using Attributes
- Base(vector): zipped SHP files imported without coordinate system information when there was a PRJ in ZIP
- Copy/Paste Format: undo/redo of actions can create multiple color scales and lead to crash
- Crash when Undo Paste Format
- Frame: Inaccurate bounding box when loading document with color scale in older versions
- Grid Data: text contents keep expanding after error until they're out of the dialog
- Internal Error after redoing unchecking of 'Show color scale' property (ColorScaleNode.cpp)
- Internal Error when certain limits & scale are applied (Axis.cpp)
- Internal Error when gridding some data using CoKriging (anisotropy.cpp)
