All graphics must be dividable by four?

Javes

Hello
I came across an old tutorial, and in that tutorial the instructor talked about an important tip regarding graphics and how it must be in dimensions that are dividable by 4 like "40x40" or "48x48"
My question is that for the old versions of gamesalad or the rule still like it is in the newest version?
And what if i can't get my graphics to be dividable by four? Can it be like "48x35" ?

Divisible by 4 is if your using Resolution Independence. If your not, they only have to be divisble by 2. If there not even when divisible by 2(or 4 if your using R.I.), they can look blurry on the device.

I am planning to create an ipad game so i don't use resolution independence.
Thanks John.

Just to chip in... Avoid odd numbers also.

Second chip - ;-) ... it seems that Apple aren't supporting 3G and 3GS any longer so always use Resolution Independence anyway for iPhones. (Or maybe it's just 3G and 3GS is hanging on in there, I can't remember, but even if so, it's days are numbered, I reckon....

As for iPads, there's a good chance that when the iPad 3 is announced in March, it'll have retina display like iPhone4's.... maybe consider that when designing for your iPad app.

ah in about 20 days we will know if iPad3 has retina display … how in the heck are we going to get a 2056x1536 into GS :
going to have get busy with the Project's Content file!

ultimately any image's maximum viewing area is the screen-size …
so for better graphic look you can use a larger image that is displays in smaller W,H (area)

if you √ Resolution Independence … GS will duplicate all images at 1/2 areaSize … your program will contain twice as many images
think it is best right now to ignore RI and work with the largest image that will display well on devices

issue with the rule of thumb ÷ 2 or 4 … thought that had to do with placement of an image X,Y on a wholePoint pixel
okay that is logical for static images
but, when an images moves in GS it does so in increments of X,Y positions …
at any given moment the position/placement of that image can be a fractional (decimal) of a pixel
(this is evinced in a scrolling bg images … gaps between images widen as the scrolling continues)

me, I use whatever size looks good!

You mean avoid odd numbers as well as making them divisible by 4 ?

@tynan
Obviously :P

Yeah... For RI you must have images to sizes that are divisible by four and not odd...

Gamesalad seems to quantize to the nearest pixel (ie: it does not anti-alias / display sub pixel events) - at least not ordinarily.

Divisible by 4 and not odd, jeez! You people want it all !

I was chipping in on not using RI, where divisible by 4 doesn't count, so the joke's on you if anything

Lol !

Damn you Ace !! And your fiendish maths.
