ANNOUNCE: Tool to flash compare images

[Adrian Carter]

Flasher 1.0, 441 kb to download from
http://www.homestead.com/adriancarter/Index.html

I googled acf, searched Pricelessware and a good lot of the rest
without finding what I wanted, so built it myself. Hope a few others
find it useful.

What it does:
Suppose you have 2 image files that you know to be different, you
want to find out, visually, exactly where the differences lie.
Example: 2 cheques, one with the correct signature, the other forged.
This pgm shows you the images, one overlaying the other, with methods to
toggle rapidly between them. The pixels that differ between the
images show up as the only parts of the picture that change.
There is also an option (Split) to view both images side by side.

Flasher relies on an OCX control provided with Imaging for Windows and
Windows Professional Imaging. Imaging for Windows comes preloaded
in Windows 98 to Windows 2000, but in XP it is necessary to buy the
professional version. If you don't have either of these imaging products
available, Flasher is not for you. Flasher is built on Windows 2000, but
I have tested it ok on XP. It *ought* to work in ME & 98, but I have no
way to actually verify this.

It handles multi-page TIFF files, and any image format that is viewable
using the abovenamed softwares. The images can be scrolled, zoomed
and paged, in tandem or independently.

I use it to compare scanned documents, but it would probably also be
useful for some photographic purposes.

Enjoy.

Adrian

Thanks
But why dont you put screenshots on your site. It allows a potential
user to get a better feel of the program.

There's a shot of the side by side view there now. But the essence of
this thing is really the flashing between 2 pics - hard to show statically.

Hi Adrian,

It seems to me that in the process of creating this you must have had
to look at the problem of image "registration" to some degree (making
sure that a top image is exactly on top of the one below).

Perhaps you are part of the way towards what some people have asked
for in this group a few months ago. A quick/easy way to "centre" text
on top of a graphic ? Vertically ? Horizontally ? Or diagonally ?
Perhaps with differing opacity ?

If you can do that then I am sure some people would appreciate such a
program/utility.

Regards, John.

Hi John,
Flasher is strictly a read-only program. I'm attempting *nothing* by way
of altering the images. I'll try to describe how you would go about using
Flasher to align 2 images that are slightly offset from each other, and
maybe
one is at a somewhat different magnification.
1. First display the images side by side. Make sure synchronisation is
switched off, and then do a rough alignment by using zoom in/out and
vertical or horizontal scrolling to change the display on just one side.
2. When it looks almost right, switch to the overlay view and start the
autoflash process (view alternates between images every X milliseconds).
While autoflashing (& still unsynchronised), use zoom & scrolling again
to fine tune the alignment.
3. When satisfied with the alignment, if you like you can switch
synchronisation
on, and zoom/scroll/page both images in tandem.

Cheers,
Adrian

Okay, thanks for the feedback/explanation/suggestion.
