Method Detail
uploadCompressedTextureFromByteArray | () | method |
public function uploadCompressedTextureFromByteArray(data:ByteArray, byteArrayOffset:uint, async:Boolean = false):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11, AIR 3 |
Uploads a compressed texture in Adobe Texture Format (ATF) from a ByteArray object.
ATF file version 2 requires SWF version 21 or newer and ATF file version 3 requires SWF version 29 or newer.
For ATF files created with png image without alpha the format string given during Context3DObject::createTexture
should be "COMPRESSED" and for ATF files created with png image with alpha the format string given during
Context3DObject::createTexture should be "COMPRESSED_ALPHA".
Parameters
data:ByteArray — a byte array that contains a compressed texture
including mipmaps. The ByteArray object must use the little endian format.
| |
byteArrayOffset:uint — the position in the byte array at which to start reading the texture data.
| |
async:Boolean (default = false)CubeTexture object dispatches Event.TEXTURE_READY.
Default value: false.
|
Throws
TypeError — Null Pointer Error: when data is null.
| |
ArgumentError — Texture Decoding Failed: when the compression format of this object cannot be
derived from the format of the compressed data in data or when the SWF version is
incompatible with the ATF file version.
| |
ArgumentError — Texture Size Does Not Match: when the width and height of the decompressed
texture do not equal the dimensions of this Texture object.
| |
ArgumentError — Miplevel Too Large: if the mip level of the decompressed texture is greater
than that implied by the size of the texture.
| |
ArgumentError — Texture Format Mismatch: if the decoded ATF bytes don't contain a texture
compatible with this texture's format.
| |
Error — 3768: The Stage3D API may not be used during background execution.
| |
RangeError — Bad Input Size: when there is integer overflow of byteArrayOffset or
if byteArrayOffset + 6 is greater than the length of data, or if the
number of bytes available from byteArrayOffset to the end of the data byte array
is less than the amount of data required for ATF texture.
|
uploadFromBitmapData | () | method |
public function uploadFromBitmapData(source:BitmapData, miplevel:uint = 0):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11, AIR 3 |
Uploads a texture from a BitmapData object.
Parameters
source:BitmapData — a bitmap.
| |
miplevel:uint (default = 0) |
Throws
TypeError — Null Pointer Error: when source is null.
| |
ArgumentError — Miplevel Too Large: if the specified mip level is greater than that
implied by the larger of the Texture's dimensions.
| |
ArgumentError — Invalid BitmapData Error: if source if the BitmapData
object does not contain a valid cube texture face. The image must have sides
equal to a power of two, and the correct size for the miplevel specified.
| |
ArgumentError — Texture Format Mismatch: if the texture format is Context3DTextureFormat.COMPRESSED or
Context3DTextureFormat.COMPRESSED_ALPHA and the code is executing on a mobile platform where runtime texture compression is not supported.
| |
Error — 3768: The Stage3D API may not be used during background execution.
|
uploadFromBitmapDataAsync | () | method |
public function uploadFromBitmapDataAsync(source:BitmapData, miplevel:uint = 0):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 24 |
Uploads miplevel 0 for a texture from a BitmapData object asynchronously.
Any draw method which attempts to use the texture fails until the upload completes successfully.
Upon successful upload, this Texture object dispatches Event.TEXTURE_READY.
Event.TEXTURE_READY is a callback to indicate that the asynchronous call received for the texture object have been executed successfully.
Upon any error during the background upload , this Texture object dispatches Event.ERROREVENT.
Parameters
source:BitmapData — a bitmap
| |
miplevel:uint (default = 0) |
Throws
TypeError — Null Pointer Error: when source is null.
| |
ArgumentError — Invalid BitmapData Error: if source if the BitmapData
object does not contain a valid texture. The image must be
equal to a power of two, and the correct size for the miplevel specified.
| |
ArgumentError — Texture Format Mismatch: if the texture format is Context3DTextureFormat.COMPRESSED or
Context3DTextureFormat.COMPRESSED_ALPHA and the code is executing on a mobile platform where runtime texture compression is not supported.
| |
ArgumentError — Asynchronous upload supported for miplevel 0 only.
| |
Error — 3768: The Stage3D API may not be used during background execution.
|
uploadFromByteArray | () | method |
public function uploadFromByteArray(data:ByteArray, byteArrayOffset:uint, miplevel:uint = 0):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11, AIR 3 |
Uploads a texture from a ByteArray.
Parameters
data:ByteArray — a byte array that is contains enough bytes in the textures internal format to fill the texture.
rgba textures are read as bytes per texel component (1 or 4).
float textures are read as floats per texel component (1 or 4).
The ByteArray object must use the little endian format.
| |
byteArrayOffset:uint — the position in the byte array object at which to start reading the texture data.
| |
miplevel:uint (default = 0) |
Throws
TypeError — Null Pointer Error: when data is null.
| |
ArgumentError — Miplevel Too Large: if the specified mip level is greater than
that implied by the larger of the Texture's dimensions.
| |
RangeError — Bad Input Size: if the number of bytes available from byteArrayOffset
to the end of the data byte array is less than the amount of data required
for a texture of this mip level or if byteArrayOffset is greater than or equal to the length of data.
| |
ArgumentError — Texture Format Mismatch: if the texture format is Context3DTextureFormat.COMPRESSED or
Context3DTextureFormat.COMPRESSED_ALPHA and the code is executing on a mobile platform where runtime texture compression is not supported.
| |
Error — 3768: The Stage3D API may not be used during background execution.
|
uploadFromByteArrayAsync | () | method |
public function uploadFromByteArrayAsync(data:ByteArray, byteArrayOffset:uint, miplevel:uint = 0):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 24 |
Uploads miplevel 0 for a texture from a ByteArray asynchronously.
Any draw method which attempts to use the texture fails until the upload completes successfully.
Upon successful upload, this Texture object dispatches Event.TEXTURE_READY.
Event.TEXTURE_READY is a callback to indicate that the asynchronous calls received for the texture object have been executed successfully.
Upon any error during the background upload, this Texture object dispatches Event.ERROREVENT.
Parameters
data:ByteArray — a byte array that contains enough bytes in the textures internal format to fill the texture.
rgba textures are read as bytes per texel component (1 or 4).
float textures are read as floats per texel component (1 or 4).
The ByteArray object must use the little endian format.
| |
byteArrayOffset:uint — the position in the byte array object at which to start reading the texture data.
| |
miplevel:uint (default = 0) |
Throws
TypeError — Null Pointer Error: when data is null.
| |
RangeError — Bad Input Size: if the number of bytes available from byteArrayOffset
to the end of the data byte array is less than the amount of data required
for a texture of mip level 0 or if byteArrayOffset is greater than or equal to the length of data.
| |
ArgumentError — Texture Format Mismatch: if the texture format is Context3DTextureFormat.COMPRESSED or
Context3DTextureFormat.COMPRESSED_ALPHA and the code is executing on a mobile platform where runtime texture compression is not supported.
| |
ArgumentError — Asynchronous upload supported for miplevel 0 only.
| |
