Fig. 2-11. Image Info dialog box with fields for changing the image dimensions.
Enter the new image dimensions (in millimeters) in the appropriate fields.
Note that the pixel size in the image ( in micrometers) will change to retain
the same number of pixels in the image.
Reduce File Size
Image files can be quite large, and computer systems do not have unlimited
memory or storage space. If you are having difficulty loading or storing a
particular image, you may want to reduce the size of the file by reducing the
number of pixels in the image. (You can also trim unneeded parts of an image
to reduce its memory size. See section 12.8.a, Cropping Images.)
This function is comparable to scanning at a lower resolution, in that you are
increasing the size of the pixels in the image, thereby reducing the total
number of pixels and thus memory size.
