Description

If ImageImageImageImageimage is displayed in WindowHandleWindowHandleWindowHandleWindowHandlewindowHandle using a 3D plot (i.e., '3d_plot'"3d_plot""3d_plot""3d_plot""3d_plot" was set using set_paintset_paintSetPaintSetPaintSetPaint), unproject_coordinatesunproject_coordinatesUnprojectCoordinatesUnprojectCoordinatesUnprojectCoordinates calculates the image coordinates ImageRowImageRowImageRowImageRowimageRow, ImageColumnImageColumnImageColumnImageColumnimageColumn, and the HeightHeightHeightHeightheight for a given point RowRowRowRowrow,ColumnColumnColumnColumncolumn in window coordinates. The window coordinates RowRowRowRowrow, ColumnColumnColumnColumncolumn must be provided in respect to the current image part. As a consequence, this coordinates are subpixel coordinates. Given the current image part (row1,column1,row2, column2), the upper left corner corresponds to the coordinates (row1 - 0.5, col1 - 0.5). Accordingly, the bottom right corner corresponds to the coordinates (row2 - 0.5, col2 - 0.5). Use get_mposition_sub_pixget_mposition_sub_pixGetMpositionSubPixGetMpositionSubPixGetMpositionSubPix or get_mbutton_sub_pixget_mbutton_sub_pixGetMbuttonSubPixGetMbuttonSubPixGetMbuttonSubPix to obtain these coordinates directly.

One of the window parameters 'save_depth_buffer'"save_depth_buffer""save_depth_buffer""save_depth_buffer""save_depth_buffer" or 'interactive_plot'"interactive_plot""interactive_plot""interactive_plot""interactive_plot" must be set to 'true'"true""true""true""true" using set_window_paramset_window_paramSetWindowParamSetWindowParamSetWindowParam. Otherwise, unproject_coordinatesunproject_coordinatesUnprojectCoordinatesUnprojectCoordinatesUnprojectCoordinates cannot be used.
