This command has been superceded by the SPixel and SPercent operators. |
Items in CAPS are 0/1 switches or switches with more options than 0/1. |
The Reduce operation allows you to decrease the size of a selected view by a percentage amount. For instance, this means that a 640 x 480 image could be reduced to a 320 x 240 image. It is important to remember that reducing an image, no matter what its resolution is, will lose image information. The loss of information can be minimized by only reducing an image by small amounts.
Trends
You will notice that all of the controls have a Trend button next to them. The trend button allows you to set that variable over a set of frames. Each frame of the animation can be thought of as a slice of time. The trends allow you to alter some, all, or none of the variables for a particular time slice. You will notice that the trend graphs have equidistantly spaced vertical lines. Each of these lines represents a frame in the animation. The number of frames can be altered using the Sequence controls... in the Timeline pull down menu. Animation lengths of 100 - 999 frames will be represented with a vertical bar being 10 frames, and animation length greater than 1000 frames will have a vertical bar for every 100 frames.

Width %
This control allows you to control the percentage decrease in size for the width of the image. The percentage decrease can range from 1% to 100%, with 100% being no change in the resolution. All changes made to the percentage value will be reflected in the New Width control. The width can be altered by moving the slide gadget, entering the appropriate percentage value, or entering the desired pixel value in the New Width control. Altering the value in the Old Width control will have no effect.
Height %
This control allows you to control the percentage decrease in size for the height of the image. The percentage decrease can range from 1% to 100%, with 100% being no change in the resolution. All changes made to the percentage value will be reflected in the New Height control. The width can be altered by moving the slide gadget, entering the appropriate percentage value, or entering the desired pixel value in the New Height control. Altering the value in the Old Height control will have no effect.

Replace Image
This option, when selected, will automatically replace the image that was being reduced. This allows you to reduce the amount of memory needed by the program by opening fewer image views. If you select to Undo the reduce operation, WinImages F/x will be able to retrieve the unaltered image. If this option is not selected, then WinImages F/x will create a new image view with the reduced image. This setting is saved when you exit the program, and reloaded when you start again.
Constant Zoom
The Constant Zoom option allows you to select how a stream of images is reduced. If this option is selected, then the images will all be reduced by a constant enlargement factor. This value is the percentage value on the Width and Height controls. If this option is not selected, then all images will be reduced to the same dimensions.
