The at text box is where you enter the output res o lu tion. This text box is
not active if the unit chosen for output size is “pixels,” when res o lu tion
is fi xed at 300 ppi. The value cho sen at other set tings should re fl ect
the res o lu tion of the out put de vice on which the fi nal image is to be
printed. The units for resolution can be selected from the res o lu tion
menu, which offers a choice of pixels per inch (ppi) or pixels per cen ti -
me ter (ppcm). The default res o lu tion is 300 ppi.

Make changes to options as described below
Keep the crop
When Keep the crop is selected, you can use the mouse to adjust the size and posi-
tion of the current crop as desired. If you enter a new value for height or width in the
Size/Resolution palette, the remaining dimension changes au to mat i cal ly to maintain a
con stant height-width aspect ratio, and scale is adjusted to refl ect the new di men sions
(scale can not be increased beyond 200%). If the image can not be output at the cur-
rent resolution using the new dimensions, resolution will au to mat i cal ly be adjusted to an
ap pro pri ate value. This option is useful when you want to specify height and width after
selecting a crop.
Keep the output size
Keep the output size locks output dimensions and fi le size at their current val ues, set-
ting the aspect ratio of the current crop according to the dimensions input in the Size/
Res o lu tion palette. This height-width aspect ratio will be main tained when you adjust
the size of the crop in the active window, and scale will be ad just ed to refl ect changes
to the size of the crop (scale can not be increased beyond 200%). If the image can not
be output at the current resolution using the new dimensions, resolution will automati-
cally be adjusted to an appropriate value. This option is useful when you want to set the
output di men sions and fi le size of the fi nal image before selecting a crop.
Width/Height
The out put dimensions for the current crop can be entered in these text
box es. The units used to describe output di men sions can be cho sen
from the menu to the right of the text boxes.
Scale/File Size
Scale (output size as a percentage of input size, maximum 200%) is displayed at the bottom of the
Size/Res o lu tion pal ette, to geth er with the uncompressed fi le size of the image that would be cre at ed at
current set tings. File size depends on the color model (RGB or CMYK) and, in the case of RGB images,
on the pixel bit-depth that will be used when the image is saved. Separate uncompressed fi le sizes are
shown for CMYK and for eight-bit and sixteen-bit RGB.
