Kozasoft: PhotoStamper: Features
Features

Lossless stamping

 

PhotoStamper doesn't modify any single pixel outside the datestamp area.
Here are examples of some image and its stamped version

Original
Stamped

A standard approach to stamping is the following. When image is opened in a graphics editor, the editor performs JPEG decompression, then a stamp is placed on the image and the modified image is recompressed again.

Unlike this method, PhotoStamper modifies and reencodes the stamp area only while leaving the rest intact. (For further details see technical details)

Images below illustrate the advantage of the lossless approach over the standard one.

Standard approach
(Adobe PhotoShop)
Lossless approach
(PhotoStamper)

These images represent differences between the original image and stamped versions for each approach. Black color corresponds to the unchanged pixels. (The actual differences are emphasized for easy viewing).

 

Reversibility

 

Because of the versatility of the JPEG standard, a stamp can be removed from the image to restore the original image pixels.
From the original image file PhotoStamper extracts data which corresponds to the stamped area and stores it as a custom JPEG data marker. During restoration, PhotoStamper just substitutes the stamped area with original data stored in the custom marker.
For further details see technical details.

 

Shell Extension

 

PhotoStamper integrates into Windows Explorer, so you can always stamp your image files directly from Explorer window. Just right-click on the file and pop-up menu will show "PhotoStamper" section with three options: "Stamp","Undo Stamp" and "Settings".




 

Multi-language support

 

PhotoStamper features various date/time formats for different languages. User can select a locale (language and country) and based on the locale PhotoStamper will suggest a list of date and time formats. User can pick one of suggested formats and/or modify format strings.

Examples of different stamps:

English (United States)
Dutch (Netherlands)
Japanese (Japan)


Customizable stamp appearance

 

Use can select stamp position from six predefined anchor points and adjust horizontal and vertical offsets from the anchor point. User can also select text font, size, color and opacity.

Note PhotoStamper suggests a font for stamp text based on Language/Country selection.

PhotoStamper can also add a transparent background area to make stamp reading easier. Background color, opacity and margins can be specified to achieve best readability for selected stamp text.

 

EXIF support

 

PhotoStamper reads image date and time from EXIF data (if available).
If EXIF data are not available the picture file creation time is used instead.

Note Most digital cameras store information about an image in EXIF format as a part of JPEG file.
