Method Detail

loadImage

public static Bitmap loadImage(java.io.InputStream is,
                               boolean closeStream)
                        throws java.lang.Exception

loadImage

public static Bitmap loadImage(java.io.InputStream is)
                        throws java.lang.Exception

Creates a Bitmap from an Inputstream by using Android's BitmapFactory.

Parameters:

is - the stream

Returns:

the bitmap

Throws:

java.lang.Exception

convert

public static Bitmap convert(Drawable dable)

Creates a Bitmap from a Drawable. This bypasses Android's BitmapFactory. However, Android is free to scale these resources on loading, so you might have to rescale them to fit. Prefer to put your images for textures into /raw if possible.

Parameters:

dable - the Drawable

Returns:

the bitmap

rescale

public static Bitmap rescale(Bitmap bitmap,
                             int width,
                             int height)

Rescales a Bitmap.

Parameters:

bitmap - the bitmap

width - the new width

height - the new height

Returns:

the rescaled bitmap
