Is the max image width in Corona 512px wide?

Just wondering as I seem to be hitting that limit.

Thanks

No, I’ve had images over 1000 pixels wide, but you have to set your config.lua file correctly else images rescale:

[lua]application =
{
content =
{
width = 320,
height = 480,
scale = “letterbox”,
fps = 30,
antialias = false,
xalign = “center”,
yalign = “center”
}
}[/lua] [import]uid: 33866 topic_id: 10753 reply_id: 39068[/import]

Aha perfect, thanks

Hmm this is weird.

Today I set up a test.

I have this as my main.lua

[lua]background = display.newImage(“back1.png”);[/lua]

Loading an image 960 x 320 pixels.

Then I have this as my config.lua

[lua]application =
{
content =
{
width = 320,
height = 480,
scale = “letterbox”,
fps = 30,
antialias = false,
xalign = “center”,
yalign = “center”
}
}[/lua]

But the image is resised on the simulator so that it fits into 480, rather than spanning 960. I must be missing something?

Thanks

Try:
[lua]local background = display.newImageRect( “back1.png”, 960, 320)
background:setReferencePoint( display.TopLeftReferencePoint )
background.x = 0
background.y = 0[/lua] [import]uid: 33866 topic_id: 10753 reply_id: 39157[/import]

Aha got it:

“The other catch is that all graphics larger than 512 x 512 must use the optional “true” flag in display.newImage(), which overrides the “safety feature” on older iPhones designed to automatically downscale large images.”

[lua]bigImage = display.newImage( “bigImage.png”, 100, 200, true )[/lua] [import]uid: 55068 topic_id: 10753 reply_id: 39158[/import]
