Color Wand

The Color Wand area selection mode allows you to select areas in the image that are similar in color to the area you clicked on.

This is similar to a flood fill operation in paint programs, but with 24 bits you need to specify a variance because in most cases, colors change so subtly that you can't see the change - but the area fill process can! The specified variance will tell WinImages F/x the amount of difference that is allowed between the selected color and surrounding colors for carrying out the current operation.

The variance values can be specified for RGB or HSL by right clicking on the Color Wand icon in the tool box, or by selecting the Color Wand Controls... option from the Area menu. This will present you a set of RGB and HSL variance sliders. Once you have selected the desired color space (RGB or HSL), and their associated variances, select the Ok button to close the dialog. The fill region will then be selected based on the Hue or RGB values of the selected color and the specified variance value.


WinImages F/x also allows you to add and subtract flood regions with previous selected flood regions and other area selections. This is particularly useful in the Draw First Working Method for selecting complex regions in an image for the application of single or multiple effects.

As an example, the Draw First Working Method area is selected, and then an effect or filter is selected for application to that region. The area that has been selected appears as a dashed outline. In the case of the Color Wand tool, the area of similar colors will be outlined with the dashed marquee.

You could then apply any operation that you like to that area by left clicking on the operation icon. This will cause WinImages F/x to carry out the operation in the highlighted region using the current operation settings. These operation settings can be changed by right clicking on the operation icon. This will bring up the operation control dialog. You could at this point alter the settings, and then apply the effect to the selected region by left clicking on the operation icon.

An area can be added to the first color wand area by holding down the shift key and then left clicking on the color in the image that you would like to add. This can be done an unlimited number of times to add many portions of the image to the area selection.

WinImages F/x also gives you the option of removing areas from the area selection by holding down the CTRL key, and then left clicking on the region you would like to remove. Once an area has been removed, no effect will happen in that portion of the image.
