ImageProxyCache

public ImageProxyCache(Context context)

Method Details

assignUniqueKeyToProxy

public boolean assignUniqueKeyToProxy(IUniqueKey key,
 ImageViewProxy proxy)

Assigns a unique key to a texture. The texture will be findable via this key using

invalid reference

#findProxyByUniqueKey()

. It is an error if an existing texture already has a key.

dropUniqueRefs

public void dropUniqueRefs()

dropUniqueRefsOlderThan

public void dropUniqueRefsOlderThan(long nanoTime)

adoptUniqueKeyFromSurface

public void adoptUniqueKeyFromSurface(ImageViewProxy proxy,
 GpuSurface texture)

Sets the unique key of the provided texture to the unique key of the GPU texture. The GPU texture must have a valid unique key.

processInvalidUniqueKey

public void processInvalidUniqueKey(Object key,
 ImageViewProxy proxy,
 boolean invalidateResource)

createTexture

@Deprecated
@SharedPtr
public @Nullable @SharedPtr ImageViewProxy createTexture(BackendFormat format,
 int width,
 int height,
 int surfaceFlags)

Deprecated.

Create a lazy ImageViewProxy without any data.

• ImageViewProxy
• ISurface.FLAG_BUDGETED
• ISurface.FLAG_APPROX_FIT
• ISurface.FLAG_MIPMAPPED
• ISurface.FLAG_PROTECTED
• ISurface.FLAG_SKIP_ALLOCATOR

createTextureFromPixels

@Deprecated
@SharedPtr
public @Nullable @SharedPtr ImageViewProxy createTextureFromPixels(@NonNull Pixmap pixmap,
 @RawPtr
 @NonNull @RawPtr PixelRef pixelRef,
 int dstColorType,
 int surfaceFlags)

Deprecated.

Creates a lazy ImageViewProxy for the pixel map.

Parameters:

pixmap - pixel map

pixelRef - raw ptr to pixel ref, must be immutable

dstColorType - a color type for surface usage, see ImageDesc

surfaceFlags - flags described as follows

See Also:

• ISurface.FLAG_BUDGETED
• ISurface.FLAG_APPROX_FIT
• ISurface.FLAG_MIPMAPPED

createRenderTexture

@Deprecated
@SharedPtr
public @Nullable @SharedPtr RenderTargetProxy createRenderTexture(BackendFormat format,
 int width,
 int height,
 int sampleCount,
 int surfaceFlags)

Deprecated.

• ISurface.FLAG_SKIP_ALLOCATOR

wrapRenderableBackendTexture

@Deprecated
@SharedPtr
public @Nullable @SharedPtr RenderTargetProxy wrapRenderableBackendTexture(BackendImage texture,
 int sampleCount,
 boolean ownership,
 boolean cacheable,
 Runnable releaseCallback)

Deprecated.

Create a RenderTarget that wraps a backend texture and is both texturable and renderable.

The texture must be single sampled and will be used as the color attachment 0 of the non-MSAA render target. If sampleCount is > 1, the underlying API uses separate MSAA render buffers then a MSAA render buffer is created that resolves to the texture.

wrapBackendRenderTarget

@Deprecated
@SharedPtr
public @Nullable @SharedPtr RenderTargetProxy wrapBackendRenderTarget(BackendRenderTarget backendRenderTarget,
 Runnable rcReleaseCB)

Deprecated.

createLazyTexture

@Deprecated
@SharedPtr
public @Nullable @SharedPtr ImageViewProxy createLazyTexture(BackendFormat format,
 int width,
 int height,
 int surfaceFlags,
 SurfaceProxy.LazyInstantiateCallback callback)

Deprecated.

Creates a texture that will be instantiated by a user-supplied callback during flush. The width and height must either both be greater than 0 or both less than or equal to zero. A non-positive value is a signal that the width height are currently unknown. The texture will not be renderable.

• ISurface.FLAG_APPROX_FIT
