lol, i diden't notice the misspelt words until after the "testing zar's theory" part

older mspaint versions were able to save as .jpg's i'm surprised it was removed.
unless you download/buy an expensive program (paint shop pro, photoshop pro) or get one with something you buy (like a digital camera that comes with MGI PhotoSuit or ULead Photo Editor) you might have to search out and find a wee small and old program called bmp2jpg. it can probably be found at http://www.download.com. however, it converts to jpgs with only 75% quality so they're a bit fuzzy. otherwise, useing the other programs listed above, you can make jpg's with the same quality as bmp's, but at a fraction of the size.

while we are talking about jpegs ... is it possible to have textures in .jpeg format (or .tiff) instead of .bmp? I mean are they supported by the client?

not currently.
but, during an in-game chat, mit mentioned that in the next version it was possible to have .jpg textures since by default directx supports .jpg.

hmm is there a 3d texturing programm that can load .atm files? Cause i got one that wont load .atm. It does load .3ds files (and maybe .x also ... but i havent got any .x atm).
I probably will have to wait till the model convert converts back to .3ds hu?

it's possible sort of. just rename your jpg to bmp and the game will see it in the list. they've loaded up fine for me.

so for instance if you have a file named "blah.jpg", rename it to "blah.bmp"

to do this you'll probably need to have the "hide extentions for known filetypes" option UNchecked in mycomputer--->tools menu--->folder options--->view tab (menu name and tab name will vary depending on your vers of windows).

this is totally unsupported and if it doesn't work for you, that's about as much info as i can give.

unless its for a brend new texture, it'd probably be best to just keep useing the .bmp one, easier to use the bmp one most/all have instead of forcing everybody to redownload a texture thats just a bit smaller.

btw, i think mit also said that jpg's woulden't look as good ingame since they don't bend well.

and if your just trying to go for low size, and get one of those other programs i mentioned earlier, you could select Color Indexing, which removes all unused colors from a pictures bit depth/pallet. like, if you have a 24-bit picture that uses only 10 shades of red and 5 shades of green, color indexing would reduce the picture to only those colors instead of the millions possible in a 24-bit picture, a 15 color picture is alot smaller then a 256 color picture, and way smaller then a 24bit picture, but while still maintaining the color quality.
no clue how exactly it works, but thats what it seems to do in all the pics i've used it on.
over all, you pretty much get a picture thats less then 25kb instead of the same picture being 192kb as a 24-bit picture (while still having the same color quality). i'll even say it probably rivals the the sizes of jpg pics..

thier are no known programs to load .atm models besides the model converter.
i believe mit had mentioned that it was meant to be this way for possible future copyright reasons. basicly, so models made FOR the game would stay WITH the game as is with many other games on the market.

i only need to kno this cuse the model lib uses jpeg only...

P3gasus · Post by **P3gasus** » Thu Dec 04, 2003 10:48 am

I thought mit had a reason for going with .bmp

I know that jpegs can be of poor quality (but i always thought bmps were worse ... not for everything i see

)

Well i think i'll give modeling a try and see where i can get with my below-basic-skills *hehe*

bmp is capable of storing nearly raw image data at higher bit depths. it's definitely closer to the image than jpeg.

bmp's colour indexing and RLE compression is closer to say, a gif file, so having the option to use jpeg or bmp is great; they compliment each other nicely by doing things the other doesn't do as efficiently.

it's pretty much the same rule of thumb as any starter web design books will tell you... for text or things with hard, solid lines and edges, colour indexing is (generally) the way to go... if you have things with lots of gradiations, smooth blended lines, etc...jpeg can (often) make it look better; results in both formats of course being dependant on how much you compress it. it's all a tradeoff of compression vs. how much the negative effects of compression are noticeable, and what type of compression is best for the job.

having fun yet?

anyway, things 8-bit bmps are good for? the petrol store, the mansion texture, that sort of thing.

things jpegs are good for? natural ground textures, texmaps, etc.

since currently we're just renaming the jpg to bmp, i dunno if the file transfer system goes by name and filesize or just name, but i'd be willing to bet it's just name, so you wouldn't force a client download for old players that already have a texture if you just kept the same name and overwrote the old bmp. i agree with zar it's probably not worth it to go back and resave things... either format gets uncompressed in-game; it's really just a question of download time.

re: the bending thing... i'd be interested in figuring out how and where jpegs start looking funky, since i've had pretty decent luck with 'em so far.

for anyone desprate to change jpeg to bitmaps and vica-versa , you can open the images in Internet Explorer(im using ver 6) save them to the other type. This works, but can make for some large bitmap files.

Indeed.

Also you can download GIMP for windows. Its a nice free photo/graphics editing program. http://www.gimp.org.

gimp is *loveee*. if you want to make high quality maps / textures / misc graphics for your islands, that's the way to go without spending a dime.

it's really unfourtunate they don't have an installer that bundles the gtk stuff... every time i send someone that link they get terribly confused on what to download. or they're still under the impression it's linux-only.

to top it all off it's gotta be one of the best mascots ever in the history of mascots. long live wilber :]

I Meant .bmp to JPEG not the other way around

i think that's why he put "and vice versa" :]
