This button allows you to use the left mouse button on your canvas to erase whatever happens to be there. Note that it is quite an inexact science; you will be erasing in the shape of circles, much like the paint roller effect in reverse. For more effective tools, look at the next two examples.
With the outline button, you may pick any region within the canvas to be moved. Click and hold down on the left mouse button to choose one corner, and once the rectangle is the correct size, release the mouse button. You will now have an outline on the canvas that you may move to any place on the canvas (or even off the canvas, as this works much faster as an erasing technique).
If you have clicked on this button, when you move into the canvas, you will see the image of a pencil on the page. Click and hold on the left mouse button while you outline the section of the canvas you wish to move. Once it is outlined you can move it with the left mouse button to another place on the canvas, or off the canvas altogether.
This will make connected lines in the color or pattern chosen from the first set of choices under the canvas. The thickness of the line is controlled by the Line button on top of the main control window.
This pencil will draw dots on the canvas, instead of a connected line. If you go slow enough with the left mouse button, of course, you may even get the dots to connect. The line thickness here has no bearing on what you will see. The color can be changed.
As you might infer, this tool sprays the color or pattern chosen on the canvas, in a circular pattern. That is, if you hold it still and use the left mouse button to spray, then you will see a circle of the color/pattern chosen.
Here is quite a powerful tool. This will fill the area the mouse is in with the color/pattern highlighted on the lower left of the canvas. If the canvas is empty, then it will change the entire background. If not, it will change the entire area it resides in, until it reaches a color that is different than the beginning one.
This button will be used to write within the canvas. You may change the Font as well as the color of the text you wish to write. Be warned: Once you are writing text, you may backspace to erase it, but if you stop, then you will have to use one of the other erasing techniques listed above to get rid of mistakes.
Left click on the canvas where you want the line to start, and then hold the button down as you move to where you wish the end of the line to be. You may change the color/pattern of the line by choosing a color/pattern from the first set of choices, and you may also change the thickness of the line using the Line option in the main control window.
The left mouse button will clicked once will mark the center of the ``spray'', and every left click after that will mark a line coming from the center. To stop this process, click the middle mouse button. Remember you may change the color/pattern and the thickness of the line using the Line option in the main control window.
This will create a curved line within the graph, where once again you have the option of changing the color/pattern of the curve, and the thickness. You must hold down the left mouse button to create the curve.
This will create the outline of a rectangular shape within the canvas. Color, pattern, and thickness may be altered as they have been above.
This is used the same as the rectangle tool above, except now you may choose an interior color for the rectangle from the second set of colors/patterns below the canvas.
You may also create circular regions within the canvas by clicking on the left mouse button and holding while you extend the oval to encircle the area you wish. Color/Pattern and thickness may be altered as they have been above.
This is the same as the above tool with the exception that the oval will be filled with the color/pattern you choose from the second set of choices under the canvas.
Use the left mouse button to start the line, and then move the mouse to the next point and click on the left mouse button again. Once you are finished with this, click on the center mouse button to stop the process, and you will see the line painted the color/pattern that you have highlighted in the first set of choices below the canvas.
This works the same as the tool above, except your finished product will be connected. You may make triangles, rectangles, rhomboids, trapezoids, etc using this tool.
Now the polygons you make (using the above procedure) will be filled with the color/pattern you have chosen from the second set of choices below the canvas.
Surprisingly enough, this is the same as the writing tool above. You will see a pencil on the canvas drawing out what you choose while you hold down the left mouse button. The only difference is again the line will become connected.
This will fill the ``bean'' you draw with the left mouse button. Note that even if your drawing doesn't connect, the end result will connect, and the color/pattern you have chosen from the second set below the canvas will fill the set.
