Internal or<h3>Intended use: Internal
"TblAsRasterDD" is a implementation of a ActiveCaching2dDD which provides for the display of data held within a table to be displayed as a raster image in an environment where individual depictions of the data are automatically cached.
This class adds to the interface defined in DisplayData . It adds the capability to display vector/array data from a Table column as a raster image. It is assumed that the Y axis is defined to be either the row number of the table column being displayed or the scalar value from the same row number in a different table column (e.g. plotting intensity as a function of frequency against row number or time determined from a different column of the table). The X axis is assumed to be a one dimensional array or vector of of data for each row in the column being displayed. It is assumed that the length of this array/vector does not change throughout the column of the table.
A TblAsRasterDD object could be construed and used as follows:
TblAsRasterDD *tardd1 = 0; tardd1 = new TblAsRasterDD("tablename"); Colormap cmap1("Hot Metal 2"); tardd1->setColormap(&cmap1, 1.0); wcHolder->addDisplayData((DisplayData *)tardd1);
To allow the display of data from a table as a raster image.
