Ok. Noobs at datachangers might be wondering, "How does the computer knows what are the dimensions of the sprite grid? How does it manages to split the grid into squares and show them the way u want?" Well the answer for these questions are in the first few magical lines in the LF2 data file.
Here is a 300 x 300 pixels sprite grid.

"file(0-8): sprite\sys\x.bmp w: 99 h: 99 row: 3 col: 3"
Now lets look in to it more carefully.
file(0-8) => Now how many sprites squares are there? there are 9 of em. There is: 0, 1, 2, 3, 4, 5, 6, 7, 8 (note how 0 counts as 1). So we write in the brackets the first number and the last.

sprite\sys\x.bmp => The location of your sprite grid.

w: 99 => So how wide each sprite box in the grid is? The width of the whole image is 300 pixels. This means that each square got 300/3(the number of boxes in the row) that is 100. But wait, if we do that then the red lines(used for neatness) in the sprite grid will appear! We don't want that!. We want the computer to ignore the red lines, therefore we will subtract 1 pixel(the width of the vertical line) from the width.This will leave us with 99.

h: 99 => So how high each sprite box in the grid is? The hight of the whole image is also 300 pixels. This means that each square got 300/3(the number of boxes in the column) that is 100. But wait, if we try to do that (again), then the red lines(used for neatness) in the sprite grid will appear! We don't want that!. We want the computer to ignore the red lines, therefore we will subtract 1 pixel(the width of the horizontal line) from the width.This will leave us with 99.

row: 3 => oh well, this thing confused me a lot in the past. When people hear the word "row", they are used to it as "the horizontal line". In fact, here, its the number of columns (wrongly called "rows") in the sprite grid. That is 3.

col: 3 => As well, this thing confused me a lot in the past too. When people hear the word "column", they are used to it as "the vertical line". In fact, here, its the number of rows(wrongly called "columns") in the sprite grid. That is 3.
