1024x1024 UIUImage limit

Hi,
Apple recommend you load images no larger than 1024x1024 dimensions.

Since you can't look into image data once it is loaded into a UIImage,
what is the regular way to zoom in?

Code:

    CGRect imageRect = CGRectMake(0, 0, 320, 480);
    [myImage drawInRect:imageRect];

This code should stretch whatever size image to fit the screen of an iPhone 4/4S.

What if you wanted to zoom in so far that one pixel took up the whole screen?

Is it acceptable to draw off screen so far that only one pixel took the whole screen by making the rectangle huge?

 

The current context will do

Zooming into sat imagery where high zoom level data is not available, so the program does it's best with an image tile of lower zoom level.

The 1, 4, 16, or however many pixels should still show the colour of vegetation.

information that I think is redundant,
but there you go....

Yes I'm trying to cheat out of tiling a raster map,
And georeferencing every tile, etc.

 

That wouldn't be hard.
Once the image is split into tiles,
Georeferencing them is.


The images are not larger than 1024x1024.
I'm asking about displaying them larger on the device by
stretching them off screen.

 

It appears to work without any problems.

even some crazy stuff like:

Code:

CGRect imageRect = CGRectMake(-1000, -1000, 3200, 4800);
    [myImage drawInRect:imageRect];
