Detailed Description

ImageCalculatorDialog is the GUI interface for the image calculation and arithmatic.

This class handles all user input, and calls other classes for actual computation.

Author:: Erica Liszewski 2006-04-20

What's New:: 2006-07-28 New Image Calculator tool auto-generates polygons based on conditional statement that includes/excludes pixels from the area

History:: 2006-08-06 Deborah Lee Soltesz added algorithm choosing functionality. The choice is passed along to the ImageShapeFinder class that implements the algorithm through the ImageCalculator class. This is a temporary capability and will be removed when the final algorithm is developed.

Todo:: dls 2006-08-06 remove algorithm choice functionality

void ImageCalculatorDialog::acceptFunction ( char * ch ) [protected, slot]

void acceptFunction(char* ch) char* ch - the function to be added Called when various buttons are pushed, The function name is passed in as a string, and the parenthesis are places at the end.

(i.e. for a sine function, you would only pass in 'sin' and the parens would be added to display 'sin()' in the equation.

void ImageCalculatorDialog::acceptFunction ( const QString & ch ) [protected, slot]

void acceptFunction(const QString & ch) const QString & ch - the function to be added Same as above, but takes a QString instead of a char*.

This is used for the functions drop-down.

void ImageCalculatorDialog::insertBand ( QListBoxItem * item ) [protected, slot]

void insertBand(QListBoxItem * item) QListBoxItem * item - the layer to be added Adds a variable representing a layer to the equation.

This is called when an item in the layers listbox is double-clicked.
