the menu.
Information (I)
Click on the Image menu, then select Information
(or use the Information tool on the toolbar.) An
information box opens, displaying the following
about the image:
Name, Compression (jpg, gif, etc.), Original size,
Current size, Original colors (color depth), Current
Colors (color depth), Disk size (bytes), Memory size
(bytes), Current directory index, Loaded in (time to
load image.)
Click the OK button when you are done viewing the
information.
Rotate Left (L)
Click on the Image menu, then select Rotate Left. The
entire image will be turned 90 degrees; the top of the
image will move towards the left.
Rotate Right (R)
Click on the Image menu, then select Rotate Right. The
entire image will be turned 90 degrees; the top of the
image will move towards the right.
Vertical Flip (V)
Click on the Image menu, then select Vertical Flip. The
entire image will be turned upside-down. Note that the
left/right orientation will remain the same.
Horizontal Flip (H)
Click on the Image menu, then select Horizontal Flip.
The entire image will be turned side-to-side, as in a
mirror.
Resize
Click on the Image menu, then select Resize. A dialog
box opens, allowing you to choose the new size. There
are several built-in choices, or you can type over the
old numbers. The first number is the width, the second
is the height, both in pixels. If you leave the Preserve
aspect ratio box checked, only type in one number, the
other will be calculated for you and the image will be
resized with the same proportions as the original.
Remember: if you have a small image and try to make
it very large (or the reverse case,) you may lose
some quality. For better results, try Resample.
Click OK to resize the image. This action can be
reversed by the Edit menu's Undo command.
The Crop command, on the Edit menu, can also be useful
in resizing.
Resample (Ctrl + R)
Click on the Image menu, then select Resample. A dialog
box opens, allowing you to choose the resample filter
to be used if you are enlarging the image. This is the
same dialog box used for resize; the image can be resized
directly with Resample.
Click OK to resample the image. This action can be
reversed by the Edit menu's Undo command.
Resampling an image often improves its quality,
especially when enlarging it. Enlarging without
resampling can often result in a blurry image.
Increase Color Depth
Click on the Image menu, then select Increase Color
Depth. A dialog box opens, showing the possible color
depths; select one.
Click OK to make the change. This action can be
reversed by the Edit menu's Undo command.
Decrease Color Depth
Click on the Image menu, then select Decrease Color
Depth. A dialog box opens, showing the possible color
depths. Select one, or type in a custom number (2 to
256.)
Click OK to make the change. This action can be
reversed by the Edit menu's Undo command.
Some images use more color depth than necessary. They
can take up a lot of extra space. Decreasing the depth
can reduce the size of the image file, often without
affecting the quality of the image. Also, some older
programs that use images can't handle the larger number
of colors.
Convert to Greyscale
Click on the Image menu, then select Convert to Greyscale.
Greyscale (or Grayscale) is actually a color mode, like
RGB. It contains more information about the photo than
Black and White. Converting from color to greyscale
will usually give a much better effect than from
color to black and white. It also prints better.
This action can be reversed by the Edit menu's Undo
command.
Negative
Click on the Image menu, then select Negative. The image
will be converted to a reversed-color version of the
original.
This action can be reversed by the Edit menu's Undo
command.
Brightness
Click on the Image menu, then select Brightness. A dialog
will appear with a slider control. Move the setting up
or down, for more or less brightness. You'll see the
image change as you move the control. When you are
satisfied, click OK. To quit without changing the
image, click Cancel.
Together with the Contrast option, this can help
correct an image that is far too light or dark.
This action can be reversed by the Edit menu's Undo
command.
Contrast
Click on the Image menu, then select Contrast. A dialog
will appear with a slider control. Move the setting up
or down, for more or less contrast. You'll see the
image change as you move the control. When you are
satisfied, click OK. To quit without changing the
image, click Cancel.

This action can be reversed by the Edit menu's Undo
command.
Color Balance
Click on the Image menu, then select Color Balance. A
dialog will appear with three slider controls, one each
for Red, Green, and Blue. Move the settings up or down,
for more or less of each color. You'll see the image
change as you move the controls. When you are satisfied,
click OK. To quit without changing the image, click
Cancel.
Sometimes an image with a lot of shadows can be
corrected better with Color Balance, than with
the Brightness / Contrast combination.
This action can be reversed by the Edit menu's Undo
command.
Gamma Correction (Ctrl + G)
Click on the Image menu, then select Gamma Correction.
A dialog will appear with a slider control. Move the
setting up or down, to adjust the intensity of the
image. You'll see the image change as you move the
control. When you are satisfied, click OK. To quit
without changing the image, click Cancel.
This action can be reversed by the Edit menu's Undo
command.

Setup dialog.

command.

Swap Colors

Colors; a sub-menu appears. Select one of the color
combinations and click on it. The image will change.
This command operates at the pixel level, changing the
color of all, or most, depending on which combination
you select. For example: if you choose RGB -> RBG,
the pixels that are green will be made blue, and the
blue pixels will be made green. (In this combination
the red pixels stay the same.) The possible swaps are:
RGB > RBG
RGB > BGR
RGB > BRG
RGB > GRB
RGB > GBR

of the dialog, and a complete description, go here.
This action can be reversed by the Edit menu's Undo
command.
