Description
If ImageImageImageImageimageimage is displayed in WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle using a 3D plot
(i.e., '3d_plot'"3d_plot""3d_plot""3d_plot""3d_plot""3d_plot" was set using set_paintset_paintSetPaintSetPaintSetPaintset_paint),
unproject_coordinatesunproject_coordinatesUnprojectCoordinatesUnprojectCoordinatesUnprojectCoordinatesunproject_coordinates calculates the image coordinates
ImageRowImageRowImageRowImageRowimageRowimage_row, ImageColumnImageColumnImageColumnImageColumnimageColumnimage_column, and the HeightHeightHeightHeightheightheight for a given
point RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn in window coordinates.
The window coordinates RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn 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_pixGetMpositionSubPixGetMpositionSubPixGetMpositionSubPixget_mposition_sub_pix or get_mbutton_sub_pixget_mbutton_sub_pixGetMbuttonSubPixGetMbuttonSubPixGetMbuttonSubPixget_mbutton_sub_pix 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""save_depth_buffer" or
'interactive_plot'"interactive_plot""interactive_plot""interactive_plot""interactive_plot""interactive_plot" must be set to 'true'"true""true""true""true""true" using
set_window_paramset_window_paramSetWindowParamSetWindowParamSetWindowParamset_window_param. Otherwise, unproject_coordinatesunproject_coordinatesUnprojectCoordinatesUnprojectCoordinatesUnprojectCoordinatesunproject_coordinates cannot
be used.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
