snibgo,

IM does have a setting, for interlace of raw images, but I am not sure that is what you need. But you can try that. See http://www.imagemagick.org/script/comma ... #interlace

Before I go any further, Thank you both. Seriously, it is kinda awesome to get this much help so quickly.

snibgo, I placed your code into a file called fix.sh and made the changes to the double %'s and ^'s per your instrucitons. When I run it -

Code: Select all

sh fix.sh T1016.png

I get

Code: Select all

fix.sh: line 2: fg: no job control
fix.sh: line 8: fg: no job control

Am I doing this properly?

I think bash shell needs a hash-bang-bin-bash first line thingy.

Yes, I saw that, couldn't make it do anything useful. Or anything at all.

snibgo, scratch that, I figured out the issue with my script. Below are the changes -

Code: Select all

convert \
  xc:black xc:white -append -write mpr:m +delete \
  -size 720x400 \
  tile:mpr:m \
  mask.png

convert \
  -size 720x480 -depth 16 -sampling-factor 4:2:2 \
  T1016.uyvy \
  -crop 100^^x50% \
  -filter Point -resize 100%x200% \
  mask.png \
  -composite \
  t.png

You are a freaking genius, IMHO. The resulting image is perfect. https://www.dropbox.com/s/pk30221axinp9um/t.png

Thank you both again. If I can work this out into a script to encompass all the steps, I will post it. I know if it helped me, someone out there is looking for a solution too.

Good stuff. I corrected my script a few seconds after posting it. Change a line from ...

Code: Select all

-crop 100^^x50% \

... to ...

Code: Select all

-crop 100%x50% \

I've made those changes to the fix.sh script. It works both ways - don't know why - but here's the modified code.

Code: Select all

convert \
  xc:black xc:white -append -write mpr:m +delete \
  -size 720x400 \
  tile:mpr:m \
  mask.png

convert \
  -size 720x480 -depth 16 -sampling-factor 4:2:2 \
  T1016.uyvy \
  -crop 100%x50% \
  -filter Point -resize 100%x200% \
  mask.png \
  -composite \
  t.png

You can actually combine this into one command line. See if this works. It seems to for me.

convert \
xc:black xc:white -append -write mpr:m +delete \
-size 720x480 \
tile:mpr:m -write mpr:tile +delete \
-size 720x480 -depth 16 -sampling-factor 4:2:2 \
T1016.uyvy \
-crop 100%x50% \
-filter Point -resize 100%x200% \
mpr:tile \
-composite \
t2.png

Agggghhh ... I made a mistake. For mask.png, I wrote:

Code: Select all

 -size 720x400 \

This should be the same size as the desired image, so:

Code: Select all

 -size 720x480 \

And this explains the blockiness at the bottom of the result. With this correction, the blockiness vanishes.

Sorry about that. (fmw42's latest script also needs this correction.)

Sorry about that. (fmw42's latest script also needs this correction.)

Thanks for pointing that out. I have edited my script above.

Hey everybody,
I hope this will help someone out in the future. The following script will take *.ithmb files from an iPod Photo Cache and convert them into usable PNG files.
****Please note, this was written for *.ithmb files from an iPhone Photo cache. I believe it would work with *.ithmb files for any iDevice with the proper changes to the

Code: Select all

-size 720x480 -depth 16 -sampling-factor 4:2:2

options in the second convert section and the proper changes to the

Code: Select all

-size 720x400

option in the first convert section to create the properly sized mask.png file.****

This code is for UNIX-based OSes, but also could be modified for Windows I suppose - I have no idea how to do that nor do I particularly care to learn so you are on your own for that part.

Just copy and paste the code into a new file and name it Convert.sh (or something similar with the .sh extension) and then run it from within the folder with the *.ithmb files from the terminal with

Code: Select all

sh Convert.sh

You will end up with 3 versions of each ithmb file - one *.ithmb version, one *.uyvy version (this is simply a renamed version of the ithmb file used for imagemagick's convert command) and a *.png version (the usable version).

Special thanks to snibgo and fmw42 here and to Keith Wiley for Keith's iPod Photo Reader http://keithwiley.com/software/keithsIP ... ader.shtml.

Code: Select all

for img in *.ithmb; do
filename=${img%.*}
cp "$filename.ithmb" "$filename.uyvy"&&
convert \
xc:black xc:white -append -write mpr:m +delete \
-size 720x400 \
tile:mpr:m \
mask.png

convert \
-size 720x480 -depth 16 -sampling-factor 4:2:2 \
"$filename.uyvy" \
-crop 100%x50% \
-filter Point -resize 100%x200% \
mask.png \
-composite \
"$filename.png"
done

I need to covert ithmb file on my windows PC programmatically either using any script or command line or programing in c++,vc++ or any other

could you help me and guide me how can i do this on windows.

thanks.

The utility works great

I have a big ITHMB file 500MB with many photos. I use windows.

The following commands work fine.

convert xc:black xc:white -append -write mpr:m +delete -size 720x400 tile:mpr:m mask.png
convert -size 720x480 -depth 16 -sampling-factor 4:2:2 F1019_3.uyvy -crop 100%x50% -filter Point -resize 100%x200% mask.png -composite F1019_1.png

The problem is it converts 1 image. The ithmb has many images.

Is there a way to break them into multiple files and then use the above commands so that I get a png output for all photos?

Whats the eof character that can be used to break the ITHMB into?

Please ignore earlier question. Found answer on other forums. ITHMB file size / 720*480*2 = Number of photos in the file.
