Color Replacer - v6.2
© 2006 Martin Vicanek. 
First release date: 05.03.2008 (Version 4.0)
Updates: 06.09.2009 (Version 6.2)


DESCRIPTION:

This filter performs color replacement functions.

The function is similar to Photoshop's Replace Color command, however, this plugin is more flexible since you can select the source and target colors independently. Therefore, it is possible to tint gray areas with an arbitrary color, which can be useful for recovering the color in overexposed areas.


INSTALLATION:

Simply unzip "colorreplacer.zip" and copy "colorreplacer.8bf" to your "\Photoshop\Plug-Ins\" folder, or whichever plugin folder your host program uses. Load your program, open an image, go to the plugins menu and select the plugin.


64-BIT SYSTEMS:

If you are using Photoshop CS4 or CS5 on a 64-bit edition of Windows (XP, Vista or 7), then there are two editions of Photoshop installed on your computer: a 32-bit edition and a 64-bit edition. Color Replacer will run on the 32-bit Photoshop edition.

Please copy "colorreplacer.8bf" to the 32-bit Plug-ins folder: Its default location is 
C:\Program Files (x86)\Adobe\Adobe Photoshop CS5 or CS4\Plug-Ins. 
The (x86) part is important!

To use Color Replacer, make sure you are running the 32-bit version of Photoshop! The default location is
C:\Program Files (x86)\Adobe\Adobe Photoshop CS5 or CS4\Photoshop.exe.
Again, the (x86) part is important.


USAGE:

Image preview area: 
Left-click to select the source color. The image protion around the clicked point will be magnified to allow more accurate selection.
Right-click and drag to move the image (only if its display size exceeds the preview area).

Zoom control: 
Use + and - to zoom in and out.

100%: 
Press to show actual pixel resolution.

Fit: 
Press to scale the image so it will fit entirely in the preview area.


"Source Color" Section
----------------------
Here you can choose or modify the source color. Click on the color pad or use the HSL sliders to set the Hue, Saturation and Lightness, respectively.


"Tolerance" section (new in Version 6.2)
-------------------
Controls the selection mask tolerance, i.e. the range of similar colors which will be included in the selection.

Chroma:
Controls how much the hue and saturation may differ from the source color.

Luma:
Controls how much the brightness may differ from the source color.

Fuzziness:
Controls the softness of the transition between selected and non-selected colors. A zero value will produce a strictly binary selection (on or off).

View Selection:
Displays the selection mask.


"Target Color" Section
----------------------
This is where you select the target color.

Copy from Source:
Copy source color to target color. Good as a starting point for further adjustments.

Click on the color pad or use the HSL sliders to set the Hue, Saturation and Lightness, respectively.


General Controls
----------------

Replace: (new in Version 6.2):
Apply the color replacement according to the current slider settings without leaving the plugin, hence facilitating multiple replacements. After pressing "Replace" the sliders will be reset to their default starting positions.

Undo: (new in Version 6.2):
Go back to previous replacement. You can press repeatedly to roll back to any point.

Reset All:
Resets all controllers to their default settings.

Exit the plugin without modifying the image.

Apply all color replacements to image and exit the plugin.

Dialog Size Grip (lower right corner):
