new problem appeared using display.newImage

Hi,

I’ve moved from build 894 to 912 and one of my projects that does not use automatic scaling (scale is set to “none” in the config file), all of a sudden behaves differently when using display.newImage/newImageRect.
On my config file, the resolution width and height are set to 1024x768. I’m also using landscape only orientation.

when loading an image to the screen, the image height, even if it should fit exactly to the simulated device, appears to be squeezed, so there are black bars on the top and bottom of the simulator. I’ve also checked on the device and it behaves the same. on build 894 it didn’t happen.

for example, I’m loading a 1280x720 image using newImageRect to the center of the screen and testing on galaxy3 whose resolution is exactly that. I see these top and bottom bars.
One way to get the image right, is to change the settings on config.lua to be 1280x720 as well, but this is not a solution of-course.

perhaps there was a degradation due to apple OS6 work?
has anyone encountered this as well? [import]uid: 118978 topic_id: 31116 reply_id: 331116[/import]

I’m using 912 and don’t see these things you described.
I don’t use content scaling. I have no config.lua file.
Try to detele it temporarly to see if something changes.
Are you 100% sure that your image is that size ?
Check one more time the line where you display the image.
If you use this line of code, it still appears to be squeezed ?
[lua]local img = display.newImageRect( “img.png”, display.contentWidth, display.contentHeight )
img.x = display.contentCenterX
img.y = display.contentCenterY[/lua] [import]uid: 138389 topic_id: 31116 reply_id: 124422[/import]

Interesting, you pointed out that you don’t use a config file.
If I drop the width and height declarations in the config file, the image looks good again.
Corona staff, can you say what changed recently in how you scale images?
Since you reccomend using a default scale on a config file, this seems like a degradation from previous behavior. what are the implications of not defining width and height on the config file?
