RELEASE NOTES
Entrance Version 1.8

-- SUMMARY
Version 1.8.18 has two significant improvements:  one for preserving the
aspect ratio of background images in a BitmapChart and one for a first look at
drawing geometric objects (e.g. polgyon) on top of other charts.  There have 
also been a number of smaller, incremental improvements.

-- SELECT IN TREE
"Select in tree" is now available in the popup menus on the query
and table tabs.

-- BITMAP ASPECT RATIO
Bitmap charts now preserve the aspect ratio of the frame bitmap when
resizing it.

-- COPY CHART 
"Copy Chart" is now in the chart popup menu for copying one
chart to the clipboard.  To make its background clear, so that whatever 
is under the chart shows through, use these commands:

  NO FRAMECOLOR
  BACKGROUND RGBA(0,0,0,0)


-- FONTSIZE, TITLEFONTSIZE
These two new keywords have been added to set the size of the default font and 
title fonts in points:
   FONTSIZE (n)
   TITLEFONTSIZE (n)  

You can also set font properties using 
   FONT (name) (style) (size)
   TITLEFONT (name) (style) (size)
The font families available depends on the OS, but "sans serif", "serif", and 
"monospaced" are always available. The font_style can be PLAIN, BOLD, or ITALIC.
Font sizes are specified in points.

-- HTML #rrggbb COLOR SYNTAX
HTML color syntax is now supported by the command line and servlet versions.  
(The destkop version supports it as well, but syntax highlighting will be 
incorrect)

-- IMPROVED LINE AND AREA DRAWING
Line and area drawing have been improved and are faster.  This blog entry has 
examples:  http://dbentrance.com/blog/?p=403

-- TRANSLATIONS
The PLOT syntax document is now available in Spanish:  
http://dbentrance.com/newdocs/es/plotsyntax.html 
as well as Japanese, French and Russian.  To switch between languages replace 
the language code "es" with "en", "fr", "jp" or "ru".  The previous release notes 
(see below) show how to add PLOT syntax notes to the Entrance Help menu.  
Please let us know if you can help with other translations!
     
-- First Look:  GEOMETRY Series Type
XYChart, BitmapChart, and EarthChart now support GEOMETRY columns.  These
are still experimental, but fun to play with.

A geometry column can contain geometric primitives in "Well Known Text"
format.  Here are some examples:

     POINT(6 10)
     LINESTRING(3 4,10 50,20 25)
     POLYGON((1 1,5 1,5 5,1 5,1 1),(2 2,2 3,3 3,3 2,2 2))
     MULTIPOINT((3.5 5.6),(4.8 10.5))
     MULTILINESTRING((3 4,10 50,20 25),(-5 -8,-10 -8,-15 -4))
     MULTIPOLYGON(((1 1,5 1,5 5,1 5,1 1),(2 2,2 3,3 3,3 2,2 2)),((6 3,9 2,9 4,6 3)))
     GEOMETRYCOLLECTION(POINT(4 6),LINESTRING(4 6,7 10))
     POINT EMPTY\n"
     MULTIPOLYGON EMPTY\n");

There is a good introduction to the MySQL "Well Known Text" extensions
here:
http://howto-use-mysql-spatial-ext.blogspot.com/2007/11/using-circular-area-selection.html

This are some pitfalls to be aware of:  
1) GEOMETRY series types are only supported by XYChart, BitmapChart or
EarthChart, so your script must begin with PLOT (one of those types).
2) MySQL binary geometry columns must be converted to text using AsText().
3) There is a bug in the desktop application that causes GEOMETERY series
to resize themselves with each repaint.

BUG FIXES
    // #468 error messages are delayed
    // #466 no frame color on rotated bar chart
    // #462 save as PNG makes chart go away when using PAGEBITMAP TEMPORARY
    // #461 BlankChart should clear background to background color
    // #447 FRAME INSETS not working for earthchart
    // #446 Running multiple scripts from the tree does not report errors properly
