Zoom Mode

If your history buffer is large enough, you can redraw a picture with different scaling factors. To select this mode press <#804#><#805#>〈<#805#>Alt<#806#>〉<#806#><#807#>〈<#807#>F9<#808#>〉<#808#><#804#> , the screen will be cleared, the current contents of the buffer will be drawn on the screen and the normal arrow mouse cursor will appear.

To select the region of the picture you want to magnify, move the arrow to the upper left corner of the region, press the left mouse button and drag the mouse to the lower right corner of the region (a ``rubber box'' should follow the arrow) and release the button. The resulting picture will be scaled so that the larger side of box will fit on the screen (if the option True Aspect is selected). You can repeat this operation until a magnification factor of thirty is reached.

<#810#><#811#>〈<#811#>Backspace<#812#>〉<#812#><#810#> will restore the previous scaling factor, the arrow keys will move the screen a third of the screen width/height in their direction, <#814#><#815#>〈<#815#>Return<#816#>〉<#816#><#814#> will reset to the original scaling and <#818#><#819#>〈<#819#>Undo<#820#>〉<#820#><#818#> will leave zoom mode. Remember that if your picture is built out a lot of vectors, the redrawing may take some time!
