AW: Best practise approach for artwork for iOS and Android?

[Tiemo Hollmann TB]

Hi Jacque,

I thought the dpi only reflects at print, because any screen has it's fixed
pixels. I think an image 800x600 with 144 dpi looks identical on any screen,
as an image 800x600 with 72 dpi because in both cases 800x600 screen pixels
are being used and there is nothing between the pixels. Or don't I see
anything here?

But perhaps I really hould try to start the project with the old 800x600
images, as you and also Kee Nethery pointed out. In this case I am not sure
what would give the better quality in point-of-view resolution. Importing
the original old 800x600 images into LiveCode and let the LiveCode engine
stretch (not distore) the images to a full screen size (with white space on
some edges at some disply sizes), or would photoshop make a better job in
interpolating pixels, if I would enlarge all images in photoshop to lets say
2732x2014 (or even 3200x2400) and let the LiveCode engine shrink the images
to fit each screen.

I would bulk-convert all the images to a higher resolution, perhaps 144dpi.
On Mac, Graphic Converter can batch process these in seconds, and I am sure
there are other programs that do the same on both Mac and Windows. Use these
higher-resolution images in your project.

On mobile, use fullScreenMode "showAll", which will automatically adjust the
display to fit any resolution and screen size on both iOS and Android.
Depending on the original card size, some edges will either be cropped or
empty space will be added. There are ways around this, mainly by displaying
an image at a larger size than the (original) card size.

There was a bug in the showAll fullscreenmode when navigating cards, but
that has just been fixed and will be in the next 9.0 release. There are also
workarounds for this right now if you don't want to wait.

This is a quick process that doesn't take much time because you won't have
to adjust every image.
