8bit images improve loading times?

POM

Hey ,
im trying to cut loading times between scenes.. does 8bit images improve loading times as oppose to 24bit png?

If so ... can someone confirm this site - http://www.8bitalpha.com - really give you 24bit to 8bit conversion ?

Cheers.
Roy.

According to the Unoffical Game Salad Cookbook they does.

Png 8 will reduce the size of your overall game. So helpful to get apps under 20mb. But the RAM usage will be the same.

I've not noticed any difference in loading times.

If you didn't already, use 'change attribute: self.image' instead of using the 'change image' attribute. Also don't allocate actors with images but leave them as white squares. This can help with loading times.

If you have a lot of sounds you could use .caf files instead of .ogg too.

Isn't GS converts all sound in one format? I was thinking it dosen't what you give GS, wav, ogg or mp3 cause it will convert the sound.

@ POM http://pornel.net/imagealpha same guy that does ImageOptim which all GS users should use.

So yes you can have 8bit pngs with alpha

also dont forget once you convert 24 to 8 bit its reduce image image quality.

Did you mean The Unofficial GameSalad Textbook? I checked, it's in the optimization chapter. I used the wrong word though... it's Indexed, not interlaced. I corrected it and it should appear in the next update. I'm waiting for GameSalad to update the software before I update the book though.

The file size of an indexed PNG is much smaller. It's like 1/4 the size of an original. So, that's good for loading times and game space. It doesn't help with RAM though.

My only concern is loading times between scenes , but after converting ALL png's to 8bit (with no lose in quality at all) and thats a LOT of images , i dont notice any change in loading times , so unless im doing something wrong i dont see the point with changing to 8bit if your game is already under 20mb .

Opps, sorry for the wrong name.

That's exactly what what author of the topic is asking about.
