9. Using Reference Angle a Enter R or select Reference from the menu to use a different base line not the X axis for the graphic angle Reference angle lt 0 0 gt b You can either enter a degree value to define the new base line or define it graphically by selecting a point If you select a point you will be prompted for the second point Reference angle lt 0 0 gt Second point Select the second point to define the line that should be rotated to a particular angle New angle in the value for the angle the new base line should take The selected data will rotate the same amount The angle of rotation will actually be the angle between the reference line positions For example if the rotation should bring a certain line to a vertical position you could draw the base line over that line and then type 90 for the new angle The default angle will then be 90 minus the angle of the base line 5 Respond yes if you do not want to retain the original data in addition to the rotated copy Note 1 If raster data is placed so that it is outside of the set raster drawing limits the portion outside the drawing limits will be lost If this happens use UNDO use gRESIZE to extend the raster limits as necessary then use gROTATE to rotate the data Nothing will be lost because all raster is within the new raster limits 184 2 Rotating raster data may distort it somewhat The line a

11. For example if the desired rotation would bring a certain line to a vertical position you could draw the base line over that line and then 168 type 90 for the new angle The default angle then will be 90 minus the angle of the base line As soon as the rotation angle has been specified the highlighted data will rotate about the base point The highlighting will be removed Move Rotate Scale You can select another option to change or press RETURN to terminate the command Using Scale 1 If you enter 5 or select Scale from the menu the pasted data will be highlighted and you can change the size of the image The default value is initially set to X 1 Y 1 Base point 2 Select the point about which the raster will be scaled This point will not change its location It also serves as the first point for the scale rectangle if you use the graphic method of scaling Scale factors lt 1 0 1 0 gt Fit 3 The data is scaled from the base point You can type the numerical values by which to scale the X and Y dimensions or select Fit and change the height and width graphically If you select Fit you will be prompted to select the original size Select original size Select two corners of a box representing the size of the original image Select new size Draw the window to show the relative size of the desired image to the reference box The data that filled the original rectangle
