tiggzi is set up for iphone4 at the moment (native app)
does it mean I should set my default screen size in tiggzi settings to 640x960 in order to have all images nicly match larger resolution in iphone4?

if so, why default resulution is set to 320px in tiggzi?
when I use 320px as default screen I make all images max 320px wide and this will look bad in iphone4, correct?

Hi Eric,
Marina helped me out with something like this, have a look at this

hope it helps

thanks micheal but I'm not sure this is a real solution for all images, it's more like a hack for background..

when creating in tiggzi for 320px and then testing on iphone4 (retina 640px) all images are fuzzy, they are simply too small

it is hard to create in tiggzi for 640x960px as web tester doesn't properly use viewport and 640px looks liek in the browser not in the phone

will it help if I have 2 version of each image in assets for example: myimage@2x.png so iphone picks that up automatically?

Sorry Eric,

I didn't mean to hijack your question, I was not aware of the problem with iphone, how ever I intended to build a different iphone app to get away for the transitions that apple dont like, I will to increase the dpi of the images I intended to use for apple. I will watch this post with interest as it looks like I will have the same issue.

cheers Eric

no problem michael, all feedback is welcome

let me ask you this, let's say I have image 100x60px for 320px
I think I can make it only 72dpi, correct? or it can be more?

when iphone4 runs this image it displays app like it was 320px width but of course in 640px resolutions so "there is not enough pixels" in the 72dpi 100x60px image and it looks fuzzy

are you saying I can save 100x60px image with large dpi and this will solve the issue?

sorry I meant ppi not dpi, dpi won't make a difference but ppi will, I intend to experiment with 160/240/320 ppi, on iphone

I found temporary solution, since tiggzi browser preview for 640x960px doesn't show native app in the device I stayed with 320px size

I export from PSD (640px) large images and use CSS to rescale image to smaller container

width:320px
height:60px
background-size:100%100%

original image is 640x120px
in iphone3/3GS shows OK but it is rescaled to 50% and iphone4 shows original size of teh image, it is nice and sharp

good stuff, you saved me some work!
nice to speak with you Eric
