# The Image menu

The Image menu contains commands that change the displayed picture. This menu is entirely disabled (all commands are dimmed) unless the QPix plug-in area has been designated by the developer as modifiable.

| Image Menu Flip Rotate Invert Filter... Filter again Image size...

Flipping and rotating images

Using these commands you can flip and rotate the image currently displayed in a QPix area.

Flipping will produce a mirror image along either a horizontal or a vertical axis. You get these options by opening the submenu under the Flip commands

Rotation options are listed in the submenu that opens under the Rotate command. Rotation can be done either by an arbitrary number of degrees (type the negative or positive number that you want), or by choosing a predefined rotation. CW means clockwise, CCW means counter-clockwise.

Inverting images

Choosing this command will result in an image that is colorized with the RGB-complements of the original colors. Best suited for grayscale or black-and-white images.

Working with filters

After choosing the Filter... menu item you will be presented QuickTime's filter definition dialog. All available filters are listed on the left. The area on the right is reserved for customizing the selected filter.

Contrary to Photoshop filters, each of which is set up in its own dialog, QuickTime offers a generic dialog for customizing filters. The thumbnail is there to preview the result of your settings on the image before accepting this dialog and applying the filter.

| Each time you click on the filter list the filter properties are reset: if you were working with a filter, choosing another you will loose the customization of the first filter. This dialog can apply one filter at a time. However, you can save a customization on disk and load it later through this dialog.

Resizing an image

The command that lets you resize an image is named Image size..., as Photoshop's corresponding command. After choosing it the following dialog appears:

You can set the new size of the image either in absolute pixels or in percentages. A handy Constrain proportions checkbox will automatically see that the aspect ratio of the original image is preserved after the resize.

| If you want to make the picture bigger than the original, remember that such advanced options as Photoshop's bicubic interpolation are not available. QPix interpolates pixels to upscale the picture, but it will not resample. A much upscaled image may lose in quality.
