createTexture

public Texture createTexture(PixelFormat formatHint,
                             Texture.Usage usageHint,
                             Texture.WrapMode wrapMode,
                             int w,
                             int h)

Description copied from interface: ResourceFactory

Returns a new Texture with the given format and edge wrapping support. Note that the dimensions of the returned texture may be larger than those requested and the wrap mode may be a simulated version of the type requested.

Parameters:

formatHint - intended pixel format of the data to be stored in this texture

usageHint - the Dynamic vs. Static nature of the texture data

wrapMode - intended wrap mode to be used for the texture

w - width of the content in the texture

h - height of the content in the texture

Returns:

texture most appropriate for the given intended format, wrap mode and dimensions

createTexture

public Texture createTexture(PixelFormat formatHint,
                             Texture.Usage usageHint,
                             Texture.WrapMode wrapMode,
                             int w,
                             int h,
                             boolean useMipmap)

Description copied from interface: ResourceFactory

Returns a new Texture with the given format and edge wrapping support. Note that the dimensions of the returned texture may be larger than those requested and the wrap mode may be a simulated version of the type requested.

Parameters:

formatHint - intended pixel format of the data to be stored in this texture

usageHint - the Dynamic vs. Static nature of the texture data

wrapMode - intended wrap mode to be used for the texture

w - width of the content in the texture

h - height of the content in the texture

useMipmap - the flag indicates should texture be created with mipmap

Returns:

texture most appropriate for the given intended format, wrap mode and dimensions

createTexture

public Texture createTexture(MediaFrame frame)

Description copied from interface: ResourceFactory

Returns a new Texture that can contain the video image as specified in the provided MediaFrame. Note that padding is almost implicit since this method has to accommodate the line strides of each plane. Also due to renderer limitations, some format conversion may be necessary so the texture format may end up being different from the video image format.

Parameters:

frame - the video image that we need to create a new texture for

Returns:

texture most appropriate for the given video image.

getRTTWidth

public int getRTTWidth(int w,
                       Texture.WrapMode wrapMode)

getRTTHeight

public int getRTTHeight(int h,
                        Texture.WrapMode wrapMode)

createRTTexture

public RTTexture createRTTexture(int width,
                                 int height,
                                 Texture.WrapMode wrapMode)

createRTTexture

public RTTexture createRTTexture(int width,
                                 int height,
                                 Texture.WrapMode wrapMode,
                                 boolean msaa)

isFormatSupported

public boolean isFormatSupported(PixelFormat format)

Description copied from interface: ResourceFactory

Returns true if the given PixelFormat is supported; otherwise returns false.

Note that the following formats are guaranteed to be supported across all devices:

     BYTE_RGB
     BYTE_RGBA_PRE
     BYTE_GRAY
     BYTE_ALPHA
 

Support for the other formats depends on the capabilities of the device. Be sure to call this method before attempting to create a Texture with a non-standard format and plan to have an alternate codepath if the given format is not supported.

Parameters:

format - the PixelFormat to test

Returns:

true if the given format is supported; false otherwise

computeMaxTextureSize

private int computeMaxTextureSize()

getMaximumTextureSize

public int getMaximumTextureSize()

Description copied from interface: ResourceFactory

Returns the maximum supported texture dimension for this device. For example, if this method returns 2048, it means that textures larger than 2048x2048 cannot be created.

Returns:

the maximum supported texture dimension
