CS297-298 Project News Feed

- Completing the first deliverable,
extracting words and pictures in
pdf file and save them into a
separate file.
- Having problem with Heap memory
when allocating byte arrays to 
save pixels of images. 
- Trying to work on the second
deliverable that is the program 
that run on mobile phones and PDAs.

- Be able to get words from letters by different distances between letters.
- save pixel coordinates to text file.

Task:
-We change to use 2D array of 
bytes to save gray scaled image 
instead of 3D array of int. So it 
saves heap memory.
_ From gray scaled image, we 
convert it to black and white 
image.
- Now we can find lines of texts or images. Then we can extract words from the lines.

Tasks:
My program is able to extract 
pixels from image files and put
them into a one dimensional array
of type int.
I convert the array of type int to
three dimensional array of type int
to process each pixel easier. The 3
dimensional array is [row][column][color].
My program can convert the image to
black and white image. 
This conversion makes edges 
dectection inside the image easier.

Tasks:
1. Learning Java Advanced Imaging
to process BMP image.
How to process a page:
1- If PDF page has text + images,
export words in text to BMP files
in sequence and scale any images
to fit target screen size.
2- If PDF page is just an image,
scan horizontally for lines and
then for each line split in to
words.
