You say a 190Kb Image..
What is that? what res? What depth?

Just curious, but if this image format is so simple, why haven't a company done it yet?

um the res doesnt matter
it is like the .raw format exept smaller and mor ecompressable

and the res is however high colors dbpro has and 800x600(until i update the core with A scroll bar)

and i dont know why

Ok, the Res does matter!! Lol.. It determines how much data is required to be stored (Unless your format is vector not bitmap based?)

So - what resolution (size) images did you use to make your 190K image? I'm only asking so I can compare to PNG, GIF, JPEG and bitmap..

um i really dont want to try to figure it out
i guess it is vector not bitmap then
it has no preset or limit to res u draw and the res is the highest and lowest x,y

(downlaod the file and oops it is 160kb oh well)

Hmm.. interesting file format.

So are you saying it only records pixels that are SET? All the others is assumes are blank?

Its not a vector.. Vector is where you specify a start and end point and thickness, etc for a line. Bitmap is for pixel based images.

Right.. So it assumes the background is a certain colour and only records the non-background colours.. Sounds a little like PNG..

How big does a file come out that has every pixel set to non-standard at sat 320x200?

um probably a bit high
and do u mean each one a different color too

it would probably range from 600kb to 1.2mb but still be compressable to under 50kb in normal zip

You think? Could you try?

I'm just wondering why this format hasn't already been done.

I mean currently, it seems to have
loseless compression (WinZIP, or whatever your want)
I assume 32bit colour
This method you use assuming a pixel is "blank" unless otherwise specified could very easily be adapted to allow transparency couldn't it?

What do the numbers in the textfile represent?

um i will eidt this post once i am done with the test cause it will take a while with that paint program and i iwlll amke a 640x480 image
with just one color but still add in about 100kb and u got colors


lemme get an exampel file and comment it

nbi ; a verifing thing to make sure this is nbi
1.6 ;version number to make sure interprter is not out of date
0 ;bgcolor red amount
0 ;bgolor green amount
0 ;bgcolor blue amount
255 ;pixel color data amount of red
255 ;pixel color data amount of greem
255 ;pixel color data amount of blue
2 ;how many pixels you are coloring wiht this color(compression encouraged)
147 ;the x coordinate of the pixel
134 ;the y coordinate of the pixel
156 ;the x coordinate fo the second pixel
123 lthe y coordinate of the second pixel




so um i trully dont know why no one has thought this up ascii compresses so much better than binary also
who knows this could trully make me rich


edit:
well i finalyl got it done btu made a special program for it that just amde a random image that used every pixel
and i almost wet my pants when i looked at it
2.8mb
561kb compressed in .zip
btu however this is with ever pixel being colored which things such as photos do but thinik of .raw some images of them are over 10mb
and this is with no artifacts or quality degrades

edit2:
so wut do u thnk higher or lower than u thought

edit3:
COULD A MOD/ADMIN PLEASE MOVE THIS TO GENERAL TALK OR DARKBAISC PROFESSIONAL DISCUSSION
(the reaosn is cause hardly anyone comes to this board i mena there are post from august on the front page)
Thanks

2.8Mb for a 640x480 image?! Thats quite high...

a completely uncompressed BMP at 640x480x24 has 3 bytes per pixel (24/8) and 640*480 pixels..
640*480*3 = 921600bytes
921600 / 1024 = 900kbytes

That zips down to about 136Kb.. This was a test file I knocked up in paint just spraying random colours for a minute.

You method will work well if there are only a few colours, not for photo's. Photo's tend to have completly unique colours.

Its a good idea, its basically pallete based then.

It sounds like you declare a colour and draw in all the pixels of that colour.

A suggestion that MAY or MAY NOT help..
When storing the pixel coords, try to do fixed width (declare at the start the width).. So say 3 digits for this example. Then put all the pixels on one line for that colour, eg:
001001512512087561
Are pixels:
1,1
515,512
87,561

Now, for that example, 5 bytes are wasted on excess zero's.. BUT you save 6 bytes from carrige returns (yes, evertime you press enter is costs 1byte, maybe 2.. I dont know if Carrige Return Line Feed is 1 or two bytes.. Think its 1).

This method could be furthered to say how many pixels you are colouring and how many digits for THAT set.. so if your only colouring a grouop in the double digit range, set it to two!

Just some thoughts.. Good idea tho!

that was my original idea i changed it because i have to read it as a string then convert it to a integer it gets pretty hard um and i got a new idea

how about instead of having
255
255
255
why nto just the actual color number although it will put more stress on the paint ti puts less stress on the core and file size
and hwo about like a little format chooser like u cna have nbifp for photos(although i would need to get something better which i ahve made somehtings thta increase size WITH a lot of colors but decrease it with a few

so i need some opinions and god how i wish i could just move this thread to the general or WIP board

got it converted now upgraded to 1.7a beta

nwo an example file would be

nbi ; a verifing thing to make sure this is nbi
1.7 ;version number to make sure interprter is not out of date
0 ;bgcolor red amount
0 ;bgolor green amount
0 ;bgcolor blue amount
1843834 ;pixel color data the rgb value
2 ;how many pixels you are coloring wiht this color(compression encouraged)
147 ;the x coordinate of the pixel
134 ;the y coordinate of the pixel
156 ;the x coordinate fo the second pixel
123 lthe y coordinate of the second pixel

Is it any better?
My advice is, any time you make a change like this you should have a tester. Like a program that makes a file full of random pixels, then a blank one, then a few pixels of same colour, etc.. That way you can compare easier.
It shuold be better as before, say you had white.. It'd be 3 bytes + 1 for CRLF, times 3.. so 12 bytes to represent a colour. Now its no more than what.. 8?

um however high dbpro goes for color which i belive is 8 digits(or bytes)

here is how i want the format to look

nbi ;verify
2.0 ;version number
16835 ;rgb value for background
4 ;the max amount of digits in one pixel x,y(like the farthest this could go is 9999 ;x 9999 ;y
283934 ;rgb value for pixel
2
00150901 ;x and y saving room on carriage returns
00191023 ;x and y for naother pixel
