Resizing Commands:

Note that none of the `resizing' commands modify the image in any way. They only affect how the image is displayed. The image remains at its original size. This allows you to arbitrarily stretch and compact the image without compounding error caused by earlier resizing. In each case, the displayed image is recomputed from the original internal image.

Normal: (Keyboard Equivalent: n) Attempts to return the image to its normal size, where one image pixel maps to one screen pixel. For example, if the image (or the current cropped portion of the image) has a size of 320x200, this command will attempt to make the image window 320 screen pixels wide by 200 screen pixels high. If the image is larger than the size of your screen, it will be shrunk (preserving the aspect ratio) until it fits on the screen.

Max Size: (Keyboard Equivalent: m) This command will make the displayed image the same size as the screen.

Maxpect: (Keyboard Equivalent: M) Makes the image as large as possible, while preserving the aspect ratio.

Dbl Size: (Keyboard Equivalent: >) Doubles the current size of the image, with the constraint that neither axis is allowed to be larger than the screen.

Half Size: (Keyboard Equivalent: <) Halves the current size of the image, with the constraint that neither axis is allowed to have a size less than 1 pixel. Note that the window size is maintained as a pair of integers. As a result you may see some integer roundoff problems.

Set Size: (Keyboard Equivalent: S) Lets you specify the exact size, or exact expansion, to display the image. Pops open a dialog box where you can type a string of the form "width x height", "expansion %", or "horiz-expansion % x vert-expansion%". The spaces between numbers aren't necessary, but the `x' and `%' characters are.

Aspect: (Keyboard Equivalent: a) Applies the `default aspect ratio' to the image. This is done automatically when the image is first loaded. Normally, the default aspect ratio is `1:1'.

4x3: (Keyboard Equivalent: 4) Attempts to resize the image so that the ratio of width to height is equal to 4 to 3.

Int Expand: (Keyboard Equivalent: I) Resizes the image to the nearest integral expansion or compression ratio. For example, if an image is currently being displayed at "162.43% x 231%", the IntExpnd command will show the image at a "200% x 200%" expansion ratio. Likewise, if an image is being shown at a "37% x 70%" expansion ratio, IntExpnd will resize it to "33% x 50%".

+10%: (Keyboard Equivalent: ) (This command is located in the upper right hand corner of the bottom three rows of buttons). Increases the current size of the image by 10%, subject to the constraint that the image cannot be made larger than the screen size (in either axis).

-10%: (Keyboard Equivalent: ) (This command is located next to the +10% command button). Decreases the current size of the image by 10%. Neither axis of the image is allowed to shrink below 1 pixel.
