Bot Questions - Banner Data Format??

Post subject: Banner Data Format??
Ive been playing with this for an hour or so and I cant figure it out.

When the server sends a player banner (packet 0x1F), it gives you 96 bytes of data. It seems to be the bitmap data (and upside down).

What I dont understand, is where youre expected to get the pallet from. I tried reconstructing the bitmap using a number of common 256 color pallets (including the one Continuum uses in its banner editor), and none of them come out exactly right. (Although, the continuum pallet was the closest).

Can someone fill me in on the part I missed? Also, if anyone has a quick method of flipping the image, include that too... Im about to go to bed and I'm feeling especially lazy =)

Yes, this is correct it is the 96 BYTEs that give you the pixel data. BMP's are stored backwards (right?); what ou need to do is take groups of 12 BYTES, and reconstruct it going backwards.

This is what is sent:
ABCDEFGHIJKL123456789012

This is how it's rebuilt:
123456789012ABCDEFGHIJKL


Thats if I'm thinking right off the top of my head..

Figured out my problem... was botching the data as I was writing it to the file(s)...my bad =(

Thanks anyway.

Win32 API automatically flips the bitmap.

HM well I did it manually w/ PHP; since PHP doesn't support BMP's in it's graphics library.

Its not flipped, its stored bottom-up. This seems weird to some people, because English is a left-to-right, top-to-bottom language. I remember reading an article a while ago as to why they originally choose this way, and it made sense at the time (just like the chopped '84 dates in timestamps a long time ago).

Doesn't have to be stored bottom up.

The 96 bytes you received are not in the typical BMP format. You are getting them top to bottom. Here's the colortable you wanted (PHP switch):

O.O

I didn't do any of that icon_wink.gif I just merely copied and pasted the last 96 bytes onto a pre-made BMP banner minus it's last 96; and badda bing icon_wink.gif

Oh, but I guess having that PHP switch would help towards creating the PNG format, etc... icon_smile.gif

Aye, I've created a nice 'Banner Emporium'.

It saves (unique) banners it sees, records who it tooks them from, who it has seen wear it to a DB. Then a crontask creates pngs in PHP from the data, then i use convert in linux to get them into BMP format and badda bing!

The site should be ready soon enough...

Youre freaky nerdy, yo know that? I hope you didnt type all that out by hand.

Lol, no way I typed that out by hand. I had written a Bitmap class for java to interpret bitmap files. All I did was have it write the color table to a file when I read in a SS graphic!

Its not flipped, its stored bottom-up.

Bottom-up = flipped?

Post subject:
I suppose it depends on your definition of flipped, flipped horizontally

instead of

012
345
678

it would be

678
345
012

My god stop all being newbs. The file format for a BMP is a known thing and is well documented.

Post subject:
Newbs...? I know the format, I was just saying that you don't have to worry about flipping/un-upsidedown-ing it yourself.
