Strange Issues with Large Image

Solar2D General Questions/Discussion
#1

Using SDK 1.1

Loading an image 320x2880, The image showed up fine, if the x and y coordinates are within 2880 offset of the origin. (image is inside a display group)

However, if I push the image to say -5000, the image simply shows up WHITE, when I move the display group’s y to 5000 to offset the position of the image.

Also, when BUILDING, the terminal is showing “FILE NOT AVAILABLE” with some of the asset files (related to compression?)

Using SDK 2.0 Beta.

The Images both show up fine, but the images are blurred, almost as if the engine has resized the images to a smaller size.

Just wondering what the limitation on the texture dimensions are?

I have tried loading the same image 320x2880, the image showed up in the visible area at a size of roughly 50x1000?

BUILDING however using SDK 2.0 gave no problems. [import]uid: 6066 topic_id: 907 reply_id: 300907[/import]

Generally the IPhone OS has a texture limitation of 1024x1024. You can’t go bigger than that, you have to tile your image. ANSCA implemented some kind of automatic image scaling. According to the docs, there should be a flag to avoid this behaviour when you load the image, but I am not sure if that works.
Performance wise you should not work with huge images, rather tile them first.

Regarding your loading error, watch out for the cases of the file names. Myimage.png is different than myImage.png. [import]uid: 5712 topic_id: 907 reply_id: 2101[/import]
