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
