This box shows you the currently selected colour. Clicking this box will open up the colour palette window.
This selects the dotted freehand drawing mode. Single dots will be drawn as you move the mouse with the left mouse button held down. With the right button you can erase previously applied paint.
This selects continuous freehand mode. As you move the mouse with the left mouse button held down a continuous line is drawn with the currently selected brush. You can also use the right mouse button to erase in a continuous line.
Select this to draw a straight line from one point to another. Select the first point with the mouse, hold down the mouse button, move the mouse to position the end point for the line, and release the mouse button. The left button draws a line, the right mouse button erases along the path of the line.
Filled Freehand allows you to draw an irregular-shaped object on the screen which is then filled. Select your start point, hold down the mouse button, and move the mouse around to draw the borders of your object. Release the mouse to finish the object. The left mouse button draws an object, the right mouse button will erase paint inside the area of the object.
This tool allows you to draw curved lines. Draw a line on the image as previously shown for the standard line tool, and once you release the mouse button you can change the line into a curve, passing through the two end-points of the line and a third point you can now select. By clicking on the same button you used to draw the line you can draw (or erase) the curve. Selecting the other button will cancel the curve operation.
Use this tool to Fill an area. Clicking on the icon a second time shows the current tolerance and smoothness settings. A tolerance can be given to fill surrounding pixels based on their `closeness` to the colour of the pixel clicked on. Smoothness will use this `closeness` to alter the intensity of the fill.
