Substitute Colors

Performs pixel by pixel substitution of colors on your image, according to the list you define. You can create each entry in the list as one of two types.

A simple one way “replace” substitution.

Example: You can replace green pixels with red.

 

A two-way substitution or “swap”.

Example: Replace a white pixel with black, a black pixel with white.

Color replacement table

Choose color pairs to be replaced or swapped from this list.

·         The Replace indicator > is a one way operation.

Example: When executed, on white-to-blue, Replace will paint any white pixel on your image blue with no other changes to the image.

·         The Swap indicator <> is a two way operation.

Example: Using white-and-blue, the program replaces white pixels with blue, and blue pixels with white.

This is a multiple selection list box. To select more than one entry, hold the Ctrl key and click the items you wish to edit.

Example: Selecting two or more items could change all from Replace to Swap or  set the same New Color for all the items.

Add

Add a new entry to the color substitution table. Initially this new entry has both colors set to white and uses a Replace > operation.

Set the colors and operational mode below the table in the Details frame.

Delete

Deletes the currently-selected entries from the color substitution table.

Delete All

Deletes all entries from the color substitution table. (As usual, you must confirm the deletion.)

Open List

Opens a color substitution list that was previously saved to a disk file.

Save List

Saves the current color substitution table to a disk file.

Apply

Applies the color substitutions defined in the table to the image currently opened in the HyperSnap workspace. Offers an immediate preview of the result.

Click the Revert button if you do not like the result.

This function must be clicked BEFORE Done, if you want to keep color changes.

Revert

When color substitutions are applied, use Revert to “go back”/restore the image in the HyperSnap workspace to its original look.

Done

When clicked before clicking Apply, closes the Color Substitution dialog box with NO color changes automatically applied to the image in the HyperSnap workspace.

To keep color changes, click the Apply button first. HyperSnap keeps your newly defined (or modified) color table for later use on this and other images. It will also re-open in the same mode.

Old Color RGB values and picker

See and modify the “Old” color part of the substitution item(s) selected in the table above. RGB = color components  Red, Green, and Blue. Each can range from 0 to 255.

Often it’s easier to use the color picker tool (eyedropper) instead of using numbers. Click the picker to select a color from anywhere on the screen, or click it to choose a color from a color table.

New Color RGB values and picker

See and modify the “New” color part of the substitution item(s) selected in the table above. RGB = color components Red, Green, and Blue. Each can range from 0 to 255.

Often it’s easier to use the color picker tool (eyedropper) instead of using numbers. Click the eyedropper to select a color from anywhere on the screen, or click to choose a color from a color table.

Replace and Swap options

Sets a “replace” or “swap” operation for the items selected in the color substitution table, above.

·         Replace > is a one way operation.

Example: When executed, on white-to-blue, Replace will paint any white pixel on your image blue with no other changes to the image.

 

·         Swap <> is a two way operation.

Example: Using white-and-blue, the program replaces white pixels with blue, and blue pixels with white.

Color matching tolerance

Allows you to decide how closely the bitmap pixels of the new color value must match the “old color” value.

·         Move the slider all the way to the left (0%) for an exact match. Only the pixels with the exact specified values of Red, Green and Blue components will be replaced.

 

·         Move the slider to right, selecting higher % values, and more and more “close color” pixels will be replaced.

 

Experiment with different values by moving the slider multiple times, then clicking the Apply button and observing the changes on the image.

Automatically apply…

Turn this on to automatically apply the defined color substitutions above to all images you capture with HyperSnap.
