Implements com.sun.prism.Texture.getContentHeight.

Doc from com.sun.prism.Texture.getContentHeight.

Returns the content height of this texture, in pixels. Note that the content size of a texture may be smaller than the requested size due to hardware restrictions (e.g. lack of non-power-of-two texture support). The content height will be less than or equal to the content height.

For example, if the hardware does not support non-power-of-two textures, and you call ResourceFactory.createTexture(400, 200), the returned Texture will have physical dimensions of 512x256, but the content dimensions will be 400x200.

@Override

Implements com.sun.prism.Texture.getContentWidth.

Doc from com.sun.prism.Texture.getContentWidth.

Returns the content width of this texture, in pixels. Note that the content size of a texture may be smaller than the requested size due to hardware restrictions (e.g. lack of non-power-of-two texture support). The content width will be less than or equal to the content width.

For example, if the hardware does not support non-power-of-two textures, and you call ResourceFactory.createTexture(400, 200), the returned Texture will have physical dimensions of 512x256, but the content dimensions will be 400x200.

@Override

Implements com.sun.prism.Texture.getContentX.

Doc from com.sun.prism.Texture.getContentX.

Returns the content x-origin of this texture relative to the upper-left corner, in pixels. This value will be greater than equal to zero.

@Override

Implements com.sun.prism.Texture.getContentY.

Doc from com.sun.prism.Texture.getContentY.

@Override

Implements com.sun.prism.Texture.getLinearFiltering.

Doc from com.sun.prism.Texture.getLinearFiltering.

Returns whether linear (smooth) filtering will be used when rendering this texture. If false, a simple nearest neighbor algorithm will be used.

Implements com.sun.prism.Texture.getMaxContentHeight.

Doc from com.sun.prism.Texture.getMaxContentHeight.

Returns the max content height of this texture, in pixels. Note that the content size of a texture may be smaller than the requested size due to hardware restrictions (e.g. lack of non-power-of-two texture support). The content height will be less than or equal to the max content height.

For example, if the hardware does not support non-power-of-two textures, and you call ResourceFactory.createTexture(400, 200), the returned Texture will have physical dimensions of 512x256 and the max content dimensions will be 512x256 minus any padding needed by the implementation to simulate edge conditions., but the content dimensions will be 400x200.

@Override

Implements com.sun.prism.Texture.getSharedTexture.

Doc from com.sun.prism.Texture.getSharedTexture.

Constructs an alternate version of this Texture with an alternate WrapMode if the two modes allow the underlying texture to be shared, otherwise a null value is returned. This method can only be used to create a shared texture for REPEAT or CLAMP_TO_EDGE textures, which must necessarily have content that spans their entire physical dimensions (if their content was smaller then they would have a _SIMULATED type of wrap mode). This method expects the texture to be already locked (and checked for a valid surface) and if it returns a non-null value then that return value will have an outstanding lock in addition to retaining the lock on the original texture. Note that if the requested WrapMode is the same as the wrap mode of this texture, then this same object will be returned after having its lock count increased by 1. Thus, in all cases, the caller is responsible for locking this texture before the call, and eventually unlocking this texture after the call, and also for eventually unlocking the return value if it is non-null.

Implements com.sun.prism.Texture.isSurfaceLost.

Doc from com.sun.prism.Texture.isSurfaceLost.

Called by code wanting to know if the RTTexture's surface is lost. This happens in some cases (mostly on Windows) when, for example, the user presses Ctrl+Alt+Delete, or the system goes to sleep.

Implements com.sun.prism.Texture.update.

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

Updates this texture using the contents of the given Image. The upper-left corner of the image data will be positioned at (contentX, contentY) of the texture, and the full width and height of the image will be uploaded. This method will cause the vertex buffer to be flushed prior to uploading the pixels.

This is equivalent to calling:

    update(img, 0, 0);

@Override

Implements com.sun.prism.Texture.update.

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

Updates this texture using the contents of the given Image. The upper-left corner of the image data will be positioned at (contentX+dstx, contentY+dsty) of the texture, and the full width and height of the image will be uploaded. This method will cause the vertex buffer to be flushed prior to uploading the pixels.

This is equivalent to calling:

    update(img, dstx, dsty, img.getWidth(), img.getHeight());

@Override

Implements com.sun.prism.Texture.update.

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

Updates this texture using the contents of the given Image. 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 prior to uploading the pixels.

This is equivalent to calling:

    update(img, dstx, dsty, srcw, srch, false);

@Override

Implements com.sun.prism.Texture.update.

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

Updates this texture using the contents of the given Image. 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.

This is equivalent to calling:

    update(img.getPixelBuffer(), img.getPixelFormat(),
           dstx, dsty, img.getMinX(), img.getMinY(),
           srcw, srch, img.getScanlineStride(), skipFlush);
