                                    the source image. <font color="navy"><b>Low 
                                    Bump</b></font> sets the intensity of bumps 
                                    where the source image is black, and <font
                                     color="navy"><b>High Bump</b></font> sets 
                                    the same for where the source image white. 
                                    When the source image lies between black 
                                    and white the level of the bumps is interpolated 
                                    between these two levels.<br> Using these 
                                    controls you can set the same level of bumping 
                                    across the image, or increase/decrease bumps 
                                    in dark or light areas. Bump levels are 
                                    usually set quite low.</p>

                                    image. The stroke maps are applied for each 
                                    active level producing grey image which 
                                    is then refined to define the intensity 
                                    of the strokes. <font color="navy"><b>Contr 
                                    Start</b></font> sets the % intensity of 
                                    the stroke maps above which the final image 
                                    is white. <font color="navy"><b>Contr End</b></font> 
                                    specifies the % intensity of the stroke 
                                    maps below which the final image is black. 
                                    Any intensity falling in between is interpolated 
                                    between the two. Setting <font color="navy"><b>Contr 
                                    Start</b></font> and <font color="navy"><b>Contr 
                                    End</b></font> to the same value reduces 
                                    the output to black or white; a slight gradient 
                                    produces a smoother transition; a large 
                                    difference between the two produces a much 
                                    softer effect. If <font color="navy"><b>Contr 
                                    Start</b></font> is set to 100 and <font
                                     color="navy"><b>Contr End</b></font> is 
                                    set to 0, you will see the final raw stroke 
                                    map image data.</p>
                                    <p align="left">Setting the value of these 
                                    two controls lower produces darker images, 
                                    and vice versa. Increasing the bump levels 
                                    results in a darker stroke map, so to maintain 
                                    similar output balance, if you increase 
                                    the bump levels you will need to decrease

                                    and <font color="navy"><b>Contr End</b></font>.</p>

                                    values gives softer images. This setting 
                                    works best with the square numbers 1, 4, 
                                    9 and 16. Non-square numbers <i>can</i> 
                                    produce artefacts depending on the settings.</td>
