Problem viewing TIFF in PDF File

["Poppenborg, Franz" <Po...@Buhlmann.de>]

Hi,

i am using FOP to assemble b/w images with some text in the footnote into a
PDF.

Now i got a problem with images which come from a certain scanner. FOP seems
to render those images but i cant see them in the resulting pdf. Acrobat
also displays the following error message "Insufficient data for an image".
By the way the image seems to be in the pdf. There are tags for the images
in it, like "/Image./Name /Im1./ ... ./BitsPerComponent 1./ColorSpace
/DeviceGray./Filter /CCITTFaxDecode ./DecodeParms << /K -1 /Columns 1664
>>".

When i look at the TIFF Files the headers present me the following data:
The good one:

IFD OFFSET = 116
The number of tags = 16

254 New Subfile Type     LONG     1      2        (2 Hex)

The bad one:
Page 1 of 1
IFD OFFSET = 24
The number of tags = 13

254 New Subfile Type     LONG     1      0        (0 Hex)

283 Y Resolution         RATIONAL 1      <16>     200 / 1 = 200.000

I've tried to convert the picture into a tiff Document with the header
information shown for the good image. I have done this with JAI. This was no
problem and the images are viewed, but my next problem is that the PDF File
grows up and is now appr. 3 times bigger then before. When i look into the
pdf i might find the answer in one line in the pdf: "./BitsPerComponent
8./ColorSpace /DeviceRGB". In other documents stands "./BitsPerComponent
1./ColorSpace /DeviceGray".

But how can i tell fop to recognize my converted image as a B/W Image.

Can anyone help?
