Note: Reducing the file size of an image will result in some loss of resolution. In
most cases this will not affect quantitation. In general, as long as the pixel
size remains less than 10 percent of the size of the objects in your image,
changing the pixel size will not affect quantitation.
Select File > Reduce File Size to open the Reduce File Size dialog box.
The Reduce File Size dialog box shows you the size of the pixels in the image
(Pixel Size: X by Y microns), the number of pixels in the image (Pixel Count: X
by Y pixels), and the memory size of the image.
As you increase the size of the pixels, the pixel count will decrease, as will the
memory size. You can increase the pixel size in either dimension (see the
following figure for an example).
