Image Controls. Directly below the
Image Display is a set of controls that allows you to adjust the basic aspects
of the drawing.
This option is used to increase or decrease the size of the pattern being drawn.
This is useful when the pattern is smaller than you want, or the pattern is too
big to fit on the screen. Values bigger than one magnify the pattern. Values
smaller than one shrink the pattern.
X-Offset/Y-Offset. These options are used to move the pattern around on
the screen. The X-Offset option moves the pattern horizontally on the screen:
negative values move the pattern left, positive values move the pattern right.
The Y-Offset option moves the pattern vertically on the screen: negative values
move the pattern up, positive values move the pattern down.
Button. Pressing the Reset button sets the scale to one and the offset
values to zero.
Figure Button. Pressing the Clear Figure button clears to the image,
setting the color to the currently specified background color.
Color Button. Pressing the Back Color button, allows you to change the
color of the back to the image. The new color is only applied when you press the
Clear Figure button described above.
Offset. This option makes it easy to move/offset a drawing to specific
place on the Image Display. It works similarly to the X-Offset/Y-Offset
described above except that it allows you to choose the location graphically by
clicking on the target location. Pressing the Click-Offset button arms the
feature. Once it is armed, clicking on any place in Image Display will change
the X-Offset and Y-Offset values so the drawing will be centered on that point.
