Lock button:
The current size of width-to-height of the target image can be
locked, allowing the ratio of width-to-height of the Source
image to change according to the scale value, or the scale
value to change according to the ratio of width-to-height of
the Source image. This is especially useful in cases where the
size of an image does not fit the size of the paper on which
you want to print the image, but you want to keep the image’s
original proportions. Enter the size of the paper in the Width
and Height fields of the Target box and then click the lock
button. The scale value is automatically changed, maintaining
the current ratio of width-to-height to fit the paper.
Scale slider:
An image can be reduced or enlarged by moving the Scale
slider. You can also click the left or right arrow to change the
image size in 1% increments.
The range of possible reduction or enlargement varies
depending on the current resolution setting.
Scale indicator:
The percentage of enlargement or reduction is shown in the
Scale indicator field. You can type a new value directly into
this field, or use the Scale slider to determine the value.
