\Standard Like most painting programs, I-Tex offers you standard rectangle operations. Press the left mouse button and drag the mouse to form a rectangle, which will be drawn with the primary color.
	Solid This function draws a rectangle on the background using the primary color. If you set the opacity value to lower than 100 the rectangle will blend with the texture.
	Outline These functions give you the ability to draw an un-filled rectangle, showing only its borders. The thickness of the borders can be adjusted with the pen size parameter. If you set the opacity value to lower than 100 the rectangle will blend with the texture.

	\Get This functions are used to get information from the texture.
	Crop to New This function copies the selected rectangle to a new texture. The rectangle has a minimum size of 16x16 pixels and a maximum size of 4096x4096 pixels. By using this function you can grab a part of an existing image to work on it with I-Tex.

	\Gradient Using these rectangle functions you can fill the selected area with a color gradient from the primary- to the secondary color. You have the following possibilities :
	Horizontal This function draws a horizontal color gradient with the secondary color at the left and the primary color at the right.
	Vertical This function draws a vertical color gradient with the secondary color at the top and the primary color at the bottom.

	\Special Here are special rectangle functions which can produce interesting effects.
	Distort The texture under the rectangle will be distorted to different directions. This can be used to simulate the erosion of an old stone wall, for example.
