So here is the result of my images after I use the image joiner tool.



and the result on my iPad is:



I have other examples, but this is the most noticeable.

I also attached the image joined png because I couldn't figure out how to UN-attach it

Other problems I'm seeing on the iPad is that that even though everything is transparent, I can see lines where the transparent image ends. It is most noticeable on Sound: On

Additionally, when I go into the game, my main backgrounds are blurry as well.

Any help would be GREATLY appreciated.

Not sure if this matters, but I use agk::setSize on the subimages. Will this affect the parent image somehow?

Have you tried experimenting with:
SetImageMinFilter( iImageIndex, mode )
SetImageMagFilter( iImageIndex, mode )?

...I assume you're using the AppGameKit Player? If this is from AppGameKit Viewer then the image will be blurry no matter what you do.

No, this isn't from the AppGameKit Player, I believe that's Tier 1? This is using Tier 2 (sorry, I should have stated that).

And to answer your question, no I haven't tried using those--researching them now...

OK, hope it helps... haven't seen this issue before but I've not been using atlas images much.

Tried using both of those functions with no noticeable difference. Tried both with 0's and with 1's for the mode.

Perhaps it's a size issue? Looking at other images I'm using, only ones that are above 1024x1024 are looking bad...

Maybe they are being reduced in size yes. Pain to edit your code but perhaps a trial with one sprite is worth it?

This looks to be the issue. Not sure what the max size of the parent image can be, but 1024x1024 and under works, and 2048x1024 does not look good.

Keep this in mind everyone!

How did you get the image joiner to work on a mac?

I didn't. I do most of my development on PC, then transfer files over to my wife's mac. Use it for a brief time, then give it back to my wife before she gets too annoyed

I have noticed with atlas file sub-images and animation sub-frames from a larger image that the sprite sometimes has a barely perceivable edge.

This only happens when one sub-image is directly adjacent to another in the source.

I presume its related to the filtering baxslash mentioned.

Giving all the images at least a 1 pixel transparent border in the source fixes it for me.

Marl, thanks for the clarification.

I would suggest that the ImageJoiner tool should do this automatically for us. I have around 300 sprites and having to do a border in the source sprites would take ages. Plus all XY co-ordinates would have to be adjusted

Marl you don't need to go into the trouble of adding a transparent border!

The single images can be odd sized and non ^2. That is not the problem. The most important thing is that when using ImageJoiner you use a ^2 size, which makes total sense.

What matters is the SetSpriteUVBorder() AppGameKit is offsetting all UV co-ords by 0.5 pixels because of scrolling! Setting SetSpriteUVBorder (iSpriteIndex, 0) fixes this problem! When using at Atlas you cannot do UV scrolling anyway!

Just another AppGameKit quirk that took a lot of investigation
