Right-hand side controls
Use any controls freely to adjust your image to whatever you need in the situation at hand.
Grid provides some additional guidelines for positioning the projection on your canvas. Despite how the grid appears on browser screen, all the lines of the grid should be exactly straight horizontally and vertically on your canvas. All circles should also be round (not oval). This, of course, assuming you don't specifically want to paint a distorted or rotated image.
Threshold slider is built combining contrast, brightness and grayscale. Use either threshold slider or contrast, brightness and grayscale settings separately.
Server-side filters (details, posterize, vectorize, outlines) can not be used simultaneously together.
Opacity is the base opacity of the image on screen. Use either opacity slider or opacity range slider.
Opacity range are two opacity values between which you want to work on. When animation is paused, you may switch between these two opacity values by clicking anywhere on page or hitting space bar. This way you can easily switch between the two opacities while painting when necessary. When the fading animation is on, it will fade between these two opacity values according to your fade durations-
Fade durations are the times in seconds that it takes for different stages of the fading animation. Fade time is used also when you use mouse clicks or spacebar to switch opacity (within opacity range) while animation is paused.
