BitMapRip Recovering Only Recovers ThumbNails FIXED...
« on: February 20, 2009, 09:39:08 AM »
Ok, I've searched the Internet and BitMapRip is definitely an excellent  :) tool for Picture recovery however it has one small problem.  ???

Most users complain that after recovering an Image all they get is a thumbnail sized image.  :o
 
The reason for this is that modern JPG's usually have a thumbnail embedded into the JPG file, hence BitMapRip finds the JPG opening bytes 0xFFD8 (http://en.wikipedia.org/wiki/JPEG) for the thumbnail and writes it as a separate file. Hence the main image body is separated from its headers and become useless.
 
To demonstrate this here is a recovery example...
try the following in a COMMAND prompt. (Stat | Run | cmd.exe)
 
REM ***
REM *** Go somewhere safe to play
REM *** Assuming C:\Temp Exists
REM ***
 
C:
CD \Temp
 
REM ***
REM *** Get an Image to Play with, this could be anything
REM *** but the M$ Image C:\WINNT\Web\Wallpaper\Follow.jpg
REM *** works well. But feel free to search your Disk for your
REM *** own JPG.
REM ***
 
copy C:\WINNT\Web\Wallpaper\Follow.jpg c:\temp
 
REM ***
REM *** Rescue Images from the Image
REM ***
 
BitMapRip Follow.jpg
 
REM ***
REM *** BitMapRip will run producing two Image files
REM ***    follow.jpg.0001.JPG
REM ***    follow.jpg.0002.JPG
REM ***
REM *** If you look at these images using Windows then
REM *** the first Image 0001 appears empty and the second
REM *** image is available as a Thumb nail Image only.
REM ***
REM *** However we can now stitch these files back together
REM *** to rescue the original image as B.JPG
REM ***
 
Copy follow.jpg.0001.JPG B.jpg
Type follow.jpg.0002.JPG >> B.jpg

REM ***
REM *** You will Now Find that the Original Image has now been recovered !
REM *** As B.JPG
REM ***
REM *** If you are recovering a large amount of JPG then once you have
REM *** Figured out which recovery files go with which (they are recovered
REM *** in the order they are found) then you are away with a simple CMD
REM *** Script  ;D

Hi rmarston!
Thanks for taking the time to do some testing and the tips.
A new version of BitmapRip is already in the works, and will fix these issues and also add some new festures, hopefully. I don't have any date to state for its release, but I will surely make a post in the news section!

Bye!
