While the 1.6 spec is OK, it is NOT the international standard with modern and
updated content.

Thanks,
I have the 1.6 specifications pdf and have used it to create what I have so
far. With regards to text it displays text just fine.
but when I add graphics it displays only the text no image.
I will look into the tools listed
Thanks again

Start by getting a copy of ISO 32000-1:2008 (the PDF Standard) and start
reading.
Then, obtain various programs that can write PDF files with various contents in
them.
Next, get a good PDF "object viewer" such as RUPS, PoDoFo, Enfocus Browser, etc.
Then start making PDFs using the apps that already know how and look at what
they wrote in the viewers and compare to the spec.
Anything else is just "hit and miss".

I would like to learn and do my own, that is why.
Because one word processor exists , we should never write another one ?
I am asking here because obviously there are people here who have more
knowledge and expertise than what I have right now.
and I still would like to learn, more
thanks

Subject: [iText-questions] Seeing guidance on PDF images
I'm trying to develop a mini PDF library and I'm stuck on getting images into
the PDF
using to read just a simple (camera generated picture) jpg file
Bitmap bmp;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bmp.compress(CompressFormat.JPEG, 100 , bos);
How do I get this into the PDF format ?
currently this is what I have
"<< /Type /XObject \n" +
" /Subtype /Image \n" +
" /Width " + bmp.getWidth() + " \n" +
" /Height " + bmp.getHeight() + " \n" +
" /ColorSpace /DeviceRGB \n" +
" /BitsPerComponent 8 \n" +
" /Length " + bos.size() + " \n" +
" /Filter /ASCIIHexDecode \n" +
">> \n" +
"stream \n" +
bos.toString() + "\n" +
"endstream \n" +
"endobj \n\n";
1) I think my /Filter is wrong not sure what to use ?
2) The test image is 341 x 256 => 87296 bos.size() returns 84156 and
yet when I count the number of bytes between stream and endstream in the
generated .pdf file I get 78814 ? What causes these changes ?
3) What is the /Filter equivalence for CompressFormat.JPEG and
CompressFormat.PNG ?
Please any help to get from the bitmap to a displayed image in the PDF file
would be greatly appreciated.
Thanks in Advance
