FineReader 8.0

[Bruno Rotondi]

Hi

After reading the images FineReader autorotates them and saves them as
0001.tif, 0002.tif etc.

But these pictures are black and white only (even there must be the
color/gray information included too)

Does anyone know how to convert these *.tif back to
color/gray-Pictures?

(or is there another newsgroup to ask this question?

Thanks for any help!

If the images have been reduced to one bit images, (B&W), there is no way to
recover the lost information. Once the data is gone, it so just gone.

Nothing has gone: I can reimport the Image and all is here - or I can
manipulate the Image and THEN the data goes away and only black/white
appears. It must have to do something with the 3 Frames these tifs
have...

When you use that "G2" excuse for an NNTP client, follow the directions
at http://cfaj.freeshell.org/google/ to try to make it include context.
Context restored:

CSM1 is (as usual) correct here. Once you save a TIFF with Group4 or
Group3 compression, it's black-and-white, and that's it. You must save
your TIFFs with LZW (or RLE, or various other methods) compressions, in
grayscale (or color) to get color. I recommend LZW, as everything can
read that.

Nothing has gone: I can reimport the [image] and all is here--or I can
manipulate the [image] and THEN the data goes away and only
black/white appears. It must have to do something with the 3 [frames]
these [TIFFs] have...

TIFF is an acronym for Tagged Image File Format, so it should really be
capitalized. If you mean that these TIFFs have 3 sub-images, it's
totally possible for a TIFF to have multiple sub-images in color or
grayscale. Some (broken) software can't deal with that.

What you really should do is *describe exactly* what you did to get
these TIFFs. http://catb.org/~esr/faqs/smart-questions.html may help
you do that. You'll want write up a short list kind of like so:

0. Start FooProgram 1.2.3 (using 'DozeXP)
1. File->Acquire Image,
2. Color->Fiddle With Image->Adjust color balance
3. File->Save As->TIFF , use $COMPRESSION.

....that way, someone who's familiar with FooProgram can say, "Don't do
that! Do @STEPS instead, and it'll all work!" HTH,

Hmmm... I already said everything I can:
1. Start FineReader 8.0
2. Import the Pictures
3. Save the Work
4. You will find 0001.tif etc. which have this special Format.

BUT NEW INFO: Opening these Tifs mit Gimp gives theses Messages:
- Sorry, can not handle YCbCr images with Planarconfiguration=2
- Unsupported layout, no RGBA loader

I think If I find a program able to convert Tiffs with
Planarconfiguration=2 I could get happy

(I opened another Thread for this Problem)

Thanks!
