ParserBase.isBitmapDataValid() contains the following lines:
var isValid:Boolean = TextureUtils.isBitmapDataValid(bitmapData);
if(!isValid) trace(">> bitmap loaded is not having power of 2 dimensions or is higher than 4096");
however, TextureUtils contains the following:
private static const MAX_SIZE : uint = 2048;
public static function isBitmapDataValid(bitmapData : BitmapData) : Boolean
{
if (bitmapData == null) return true;
var w : int = bitmapData.width;
var h : int = bitmapData.height;
if (w < 2 || h < 2 || w > MAX_SIZE || h > MAX_SIZE) return false;
if (isPowerOfTwo(w) && isPowerOfTwo(h)) return true;
return false;
}
so it seems the size limit on Bitmap textures is really 2048. Either the MAX_SIZE value should be increased to 4096 or the trace should be changed, perhaps moved into the TextureUtils class so you can do this:
public static function isBitmapDataValid(bitmapData : BitmapData) : Boolean
{
if (bitmapData == null) return true;
var w : int = bitmapData.width;
var h : int = bitmapData.height;
if (w < 2 || h < 2 || w > MAX_SIZE || h > MAX_SIZE)
{
trace("Bitmap width is "+bitmapData.width+" and height is "+bitmapData.height+". Max size is "+MAX_SIZE+" and min is 2");
return false;
}
if (isPowerOfTwo(w) && isPowerOfTwo(h))
{
return true;
}
else
{
trace("Bitmap width is "+bitmapData.width+" and height is "+bitmapData.height+". Each side should be a power of 2.");
}
return false;
}
