How to multiple image TIFF files be converted to JPEG files

conversionimagesjpegtiff

How can multiple image TIFF files be converted to JPEG files in a batch manner?

Update 1: convert on Linux (part of ImageMagick) as suggested by Miss Cellanie and glallen worked. It was straightforward. I downloaded the ISO image of the netbook version of Kubuntu 9.1, burned it onto a DVD, restarted, started a command-line window, changed current directory to where inter2.tif was and typed:

    convert -separate inter2.tif new_inter2.jpeg

This created the 3 expected images, new_inter2-0.jpeg, new_inter2-1.jpeg and new_inter2-2.jpeg. Some error messages were displayed:

convert: incorrect count for field "DateTime" (21, expecting 20); tag trimmed. `inter2.tif' @ tiff.c/TIFFWarnings/526.
convert: inter2.tif: unknown field with tag 317 (0x13d) encountered. `TIFFReadDirectory' @ tiff.c/TIFFWarnings/526.
convert: inter2.tif: unknown field with tag 33628 (0x835c) encountered. `TIFFReadDirectory' @ tiff.c/TIFFWarnings/526.

I have a lot of microscopy images of cells. They are in the TIFF format, one TIFF file per sample/cell picture and 3 channels/images in each TIFF file (3 different light wavelengths).

The TIFF files need to be converted to JPEG files in a batch manner (user intervention should not be required), 3 JPEG files for each TIFF file (corresponding to the 3 wavelengths).

I have tried to use the command-line tool tiffsplit that is included with LibTIFF to do the first step, extracting the 3 images from the original TIFF to 3 new TIFF files. But it crashes with the TIFF files I have (on Windows XP 64 bit, DEP enabled). The error message is:

Unhandled exception at 0x6fd853d1 in tiffsplit.exe: 0xC0000005: Access violation writing location 0x6fdc8ddb

Do you know of another solution? Either on Windows or Linux.

Here is a sample TIFF file (3.8 MB). Composite image (single JPEG file made by importing in MS Paint and saving as JPEG) to give you an impression of what it is:

There's probably a slightly more elegant way, but this should do it for you:

for FILE in $(ls *.tif); do \
    for I in R G B; do \
       convert -channel $I -separate -format jpg $FILE $FILE-$I.jpg ; \
    done ; \
done ; \ 
rename s/\.tif\-/\-/ *.jpg

Use nconvert with its infinite possibilities.

NConvert is a batch utility for converting graphic files.

Import about 400 graphic file formats
Export about 40 graphic file formats
Multipage TIFF, Animated GIF, Animated ICO support
Resize
Adjust brightness, contrast...
Modify number of colors
Apply filters (blur, average, emboss, ...)
Apply effects (lens, wave, ...)
And many many other things

Read this User guide for some examples to start.
I uploaded the full help file on pastebin to see what parameters are available

Note: A graphical front-end using nconvert is XnConvert

To answer hemalshah' initial question

download nconvert and place it somewhere
create a .cmd in the same folder and copy&paste the following command
Customize the path to your own .tiff image and execute the batch file.
This will create a new mysource_1.tiff file in the source folder (use -overwrite to replace the original)

nconvert -out tiff -multi -dpi 100 -c 4 -keepdocsize -keepfiledate mysource.tif

this can easily be expanded to convert thousands of files at once.
Nconvert understands textfiles with image paths as input
-out tiff -multi is necessary to tell nconvert to produce multi-page TIFF files
-dpi 100 obviously sets the new DPI
-keepdocsize preserves your page height and width
-keepfiledate preserves the original create date

-c 4 sets the compression method. I recommend ZLIB since it produces the smallest files
_{Other compression methods}

1 (Rle), 2 (LZW), 3 (LZW+Prediction), 4 (ZLIB)
5 (CCITT G3), 6 (CCITT G3-2D), 7 (CCITT G4) only B/W
8 (JPEG) only 24/32 bits

I separated the output tiff into single page tiff files to see if all pages are set to 100 DPI. As the screenshot proves, nconvert will solve your issue.

Ffmpeg | batch convert | make same filename

FFMpeg can't write on the same file while reading from it because it can cause errors.
The only way to do it is to convert into another file and replace the original files.
Or you can convert it to another folder and replace the original folder, it's easier.

For Windows:

mkdir outdir
for %i in (*.bmp) do (
ffmpeg -i %i -ar 22050 outdir\%i
)

Note: Replace %i with %%i when putting it in Windows batch file.

For Linux:

mkdir outdir
for i in *.wav; do
  ffmpeg -i $i -ar 22050 outdir/$i;
done

Now just replace your directory with outdir.

For your case:
If you want it for Counter Strike:GO or HLDJ, then look here. HL requires more settings,
audio must be mono (add -ac 1 flag in FFMpeg) and 16-bit (add -acodec pcm_s16le).
So your FFMpeg command (on Linux) will look like this:

mkdir outdir
for i in *.wav; do
  ffmpeg -i $i -acodec pcm_s16le -ac 1 -ar 22050 outdir/$i;
done
