1.52a 23 April 2018

• Thanks to Michael Schmid, added Apply Macro commands to the Edit and contextual (right click pop-up) menus of table windows. Also added the ResultsTable.applyMacro() method (JavaScript example).
• Thanks to Ron DeSpain, tables created by the Image>Overlay>List Elements command can be renamed "Results" and the values accessed using the getResults() and getStringResult() macro functions.

• Added 20 macro functions that work with tables. They operate on the current (frontmost) table or an optional title argument can be provided (e.g., Table.size("My Table")). Examples: Sine/Cosine Tables, Rearrange Table and Access Tables.
  • Table.create() - opens a new table
  • Table.reset() - resets (clears) the table
  • Table.size() - number of rows in the table
  • Table.title() - title of the current table
  • Table.headings() - column headings as a tab-delimited string
  • Table.get(columnName, rowIndex) - returns a numeric value
  • Table.getColumn(columnName) - returns a column as an array
  • Table.getString(columnName, rowIndex) - returns a string value
  • Table.set(columnName, rowIndex, value) - sets numeric or string value
  • Table.setColumn(columnName, array) - sets an array as a column
  • Table.update() - updates table window
  • Table.applyMacro(macro) - applies macro code to table
  • Table.rename(title1, title2) - renames a table
  • Table.save(filePath) - saves the table
  • Table.open(filePath) - opens a table
  • Table.deleteRows(index1, index2) - deletes specified rows
  • Table.renameColumn(oldName, newName) - renames a column
  • Table.deleteColumn(columnName) - deletes specified column
  • Table.showRowNumbers(boolean) - enable/disable row numbers
  • Table.showArrays(titleAndOptions, array1, array2, ...) - displays arrays in a table (like Array.show)

• Thanks to Philippe Carl, fixed a bug that caused the Image>Hyperstacks>Reduce Dimensionality command to not preserve the "Info" image property.
• Thanks to Jan Eglinger, fixed bugs that caused the roiManager("open",path) macro function to ignore the roi name and roiManager("save",path) not to be recorded when 'path' ended in ".roi".
• Thanks to Norbert Vischer, fixed a bug that caused the Image Calculator to not correctly calculate the result when the operation is MULTIPLY or DIVIDE, the 1st image is 8 or 16 bit, the 2nd image is 32 bit and "32-bit result" is unchecked.
• Thanks to Mark Rivers, fixed a bug that caused ImageJ to not correctly open some uncompressed planar RGB TIFFs.
• Fixed a 1.51s regression that caused statistical calculations on small 16-bit images or selections to be much slower.
