Immediate Action mode
The immediate mode is very simple in concept: When you create an area selection, as soon as the selection is complete, the change or effect is applied to the action image immediately. This sounds simple - in fact, it sounds so simple that it doesn't sound very powerful, but that's not so. WinImages F/x has a number of tricks you can use to make this very powerful, very accurate, and still simple and fast. The key rests in the use of the right mouse button during area selection, and the boolean modifiers, which we will discuss a little further on.
Select, then Operate mode
This mode works more like Photoshop ®, in that you create the selection step by step, editing and changing it using the various area tools, and then when the area is exactly as you wish, you left-click on the operation you want to perform, and it then is applied to the area selection you made.
Stroking and Regional Tools
Some tools can be used both to select entire regions, or areas, and also to create paths that brush-strokes can follow. Examples of this are the ellipse and the freehand tool. Looking at the area toolbox, the top nine tools are the ones that can both stroke and fill.
These are the tools that can only create filled areas:
WinImages F/x handles text as one or more area selections: If you memorize anything about WinImages F/x, it should be this! There is no more often misunderstood tool in WinImages F/x than the text tool.
The idea is this: If you want to create text as almost every other program in the world does it, you select the color fill operator, then the text tool, and bingo, you've got it done. It works just as you'd expect it to. And, it only works as you'd expect it to if you use the color fill tool!
But! If you'd instead prefer to turn the surface of the image into a kaleidoscope underneath the word "FOO", then select the kaleidoscope operator, the text tool, and type in "FOO". It's just that easy. In fact, any effect in the program may be executed in the shape of the area selection - and that capability is so powerful, you could spend weeks experimenting with nothing else.

If you right-click on the A/A button in the area toolbox, a dialog opens that allows you to set the feathering for the area selection. Feathering is a measure of how soft the edge of the area selection will be. This function is also available from the area menu.
WinImages F/x's color keying also creates an area, or areas, but does not create a path. You can key using RGB or HSV methods. You can also key using any of the area tools along with the special color key modifier; more on that below.
Boolean Tool Modifiers
There are a number of "boolean" tool modifiers you can use. These do things like invert the area selection, or mix the current selection with the one made previously. You'll find these at the bottom of the area toolbox. They're easy to spot, because they are all in the second row from the bottom of the toolbox.
Selection Aspect Ratio Control
Often, you'll want to control the shape of the area selection so that it conforms in a general sense to the shape of the image, or to a perfect square or circle. These tools prvide those capabilities, and also allow you to constrain the shape of the area selection to that of the source image, which can be very useful when compositing images.
Splattering is a neat modifier that allows you to throw many ellipses or rectangles at an image or layer in one step. Splatter runs inside the area selection you make using any tool.
Number of Levels: 0 to infinity
You can choose how many records are kept at one time, from none to as many as your memory will hold. As far as WinImages F/x is concerned, there is no limit - but you will eventually run out of memory if you set the control to infinite. At least, with today's PC's you will. Who knows about the future?
Setting and Using the History
Use the Number of Undo Levels in the Settings menu to control the history. To use it, just click the thumbs-up and thumbs-down tools at the upper right of the main window.
What is kept in the History
WinImages F/x keeps the RGBA data (of course) that actually comprises the image itself. But it also records aspect ratio changes, names and much more when needed. It can even restore an image after a resize operation!
The magic wand allows you to click on an area, and based on the method and tolerance you set (using the right mouse button on the wand tool), the wand will make an area selection for you, in which any effect you like may be applied.
This is where it gets interesting. The color key modifier (shown as a gold key over a rainbow in the area tool box) can make area selection become a color key. And there are a number of powerful keying methods available. RGB and HSV, of course, but also our unique and powerful color space keying methods work here. The color space key can actually measure, remember, and use every color in the keying sample area - even if there are millions of them! You can learn more about color space keying here. Plus, there are specialized keying modes that work with heightfields - you can key on height and steepness, two key concepts that will allow you to manipulate heightfield data in a very intuitive and effective manner.
Finally, you can color-key in a non-destructive manner by using image layers. You set the layer to the keying color or colors, and then choose the appropriate layer keying mode. These modes are discussed here.
