13.5 Pixel Dimensions
What are pixel dimensions?
Pixel dimensions refer to the number of pixels in the width and height of a bitmapped image. Thus an image
with pixel dimensions of 200 x 300 has a width of 200 pixels and a height of 300 pixels. Pixel dimensions do
not define a fixed size for the bitmapped image. Rather the resolution determines the final physical
dimensions of the image. See Resolution (Page 172) for help understanding resolution in PlanetPress Design.
You can adjust the pixel dimensions of a bitmapped image to adjust the size it occupies at a given resolution.
This is called resampling the image, and it is particularly useful for large image files that contain more pixels
than are necessary to produce the highest quality output.
