pack-priv Texture createSharedLockedTexture(Texture.WrapMode altMode)

Implements abstract com.sun.prism.sw.SWTexture.createSharedLockedTexture.

Doc from com.sun.prism.sw.SWTexture.createSharedLockedTexture.

Returns a new Texture object sharing all of the information from this texture, but using the new WrapMode. The new texture will be locked (in contrast to the similarly-named method in BaseTexture).

Parameters
altMode:Texture.WrapMode

the new WrapMode for the new texture

Returns:Texture

a new, locked, texture object sharing all information with this texture except for the WrapMode

public void update(Buffer buffer, PixelFormat format, int dstx, int dsty, int srcx, int srcy, int srcw, int srch, int srcscan, boolean skipFlush)

Implements com.sun.prism.Texture.update.

Doc from com.sun.prism.Texture.update.

Updates this texture using the contents of the given Buffer. The upper-left corner of the image data will be positioned at (contentX+dstx, contentY+dsty) of the texture, and the source region to be uploaded will be srcw by srch pixels. This method will cause the vertex buffer to be flushed unless skipFlush is true.

Parameters
format:PixelFormat

the format of the data contained in the pixel buffer

dstx:int

the x-offset of the image data, in pixels, relative to the contentX of this texture

dsty:int

the y-offset of the image data, in pixels, relative to the contentY of this texture

srcx:int

the x-offset into the source buffer, in pixels

srcy:int

the y-offset into the source buffer, in pixels

srcw:int

the width of the pixel region from the source buffer

srch:int

the height of the pixel region from the source buffer

srcscan:int

the scanline stride of the source buffer, in bytes

skipFlush:boolean

if true, the vertex buffer will not be flushed

public void update(MediaFrame frame, boolean skipFlush)

Implements com.sun.prism.Texture.update.

Doc from com.sun.prism.Texture.update.

Updates this texture using the contents of the provided MediaFrame. The source and destination coordinates are implicit, you can only update the entire video texture.

Parameters
frame:MediaFrame

the source video buffer to update the texture data from

skipFlush:boolean

if true, the vertex buffer will not be flushed
