Eliminate White filter ver. 1.0w  (international version)


 Introduction 

The Eliminate White filter is a simple Photoshop plug-in filter that
generates transparency in a layer based on the "whiteness" of each 
pixel color. This is useful when you want to "peel" an image off the 
white background and put it on an independent layer. It's also useful 
for creating interesting effects. Please read the How-To section 
below for more information.

The filter was created using the Filter Factory, a scriptable plug-in 
found on the Adobe Photoshop 3.0x /4.0x Deluxe CD-ROM. While the 
Eliminate White filter itself is freeware, the copyright of the 
Filter Factory portion is owned by Adobe Systems Incorporated. You 
can distribute this filter freely as long as the original archive 
file is unaltered. For distribution on CD-ROMs such as freeware 
collection, uploading to BBSs or to ftp/www sites on the Intenet,
you must get prior permission from the author.

 How to install 

Like other Photoshop plug-in filters, simply copy the file labeled 
"elimwhit.8bf" with PLUG-IN icon into your Plug-ins folder and 
restart Photoshop.


 How to use 
The Eliminate White filter generates transparency based on the 
"whiteness" of the color of each pixel. This is useful when you want 
to "peel" an image off the white background to an independent layer. 
This works nicely with gradations, too. Here's the basic how to use 
this filter:

1:
Prepare a target image as a non-background layer and select the layer 
in the Layers palette. (Note: the Eliminate White filter works with 
RGB images only.) You can convert a background layer to a non-
background layer by double-clicking "Background" in the Layers 
palette. 

2.
Apply the filter by choosing "Eliminate White" from the Filter > 
Transparency submenu. This creates transparency based on the 
"whiteness" of each pixel value. At this point, the image may look 
less saturated than before applying the filter.

3.
This is an important step. Run Photoshop's "Layer > Matting > Remove 
White Matte" command to the same layer. Now, the original saturation 
of the image 
comes back, and all white areas becomes transparent. In Photoshop 
3.0x, "Remove White Matte" command is found under "Select" menu.



 Source script 
The "ewscript.afs" file contains the original script of the Eliminate 
White filter. If you are interested in how the filter works, try 
loading the .afs file using the "Load" button in the Filter Factory 
plug-in dialog box. The Filter Factory plug-in itself can be found in 
the "Other Goodies" folder on Adobe Photoshop CD-ROM. The Filter 
Factory plug-in is an optional one and cannot be installed with the 
Adobe Photoshop installer. The Filter Factory plug-in is not 
available on the floppy disk set of Photoshop.
