Base Interfaces

XIeeeFloatReadOnlyBitmap
┗ XBitmap

XBitmap

(言及／関連d interface's 要約:): This is a generic interface to a bitmap.

Usage 制限s

not published

Description

専攻するd interface for bitmaps 含む／封じ込めるing IEEE floats as their color 構成要素s. In contrast to XIeeeFloatBitmap, this interface only 許すs read-only 接近.

Use this interface for e.g. bitmaps that are calculated on-the-飛行機で行く, or that are pure 機能の, and thus cannot be 修正するd.

If you get passed an instance of XHalfFloatReadOnlyBitmap that also supports the XVolatileBitmap interface, things become a bit more 複雑にするd. When reading data, one has to check for both VolatileContentDestroyedException and mismatching FloatingPointBitmapLayout return values. If either of them occurs, the whole bitmap read 操作／手術 should be repeated.

Methods' 要約
getData	Query the raw data of this bitmap.
getPixel	Get a 選び出す／独身 pixel of the bitmap, returning its color value.
getMemoryLayout	Query the memory layout for this bitmap.

Methods' 詳細（に述べる）s

getData

sequence< float >
getData(	[out] FloatingPointBitmapLayout	bitmapLayout,
	[in] ::com::sun::星／主役にする::geometry::IntegerRectangle2D	rect )
raises(	::com::sun::星／主役にする::lang::IndexOutOfBoundsException, VolatileContentDestroyedException );

Description

Query the raw data of this bitmap.

Query the raw data of this bitmap, in the 判型 as defined by getMemoryLayout(). With the given rectangle, a subset of the whole bitmap can be queried. When querying subsets of the bitmap, the same scanline padding takes place as when the whole bitmap is requested.

公式文書，認める that the bitmap memory layout might change for volatile bitmaps.

Parameter bitmapLayout

The memory layout the returned data is in.

Parameter rect

A rectangle, within the bounds of the bitmap, to retrieve the contens from.

Throws

VolatileContentDestroyedException if the bitmap is volatile, and the content has been destroyed by the system.

Throws

com::sun::星／主役にする::lang::IndexOutOfBoundsException if parts of the given rectangle are outside the permissible bitmap area.

getPixel

sequence< float >
getPixel(	[out] FloatingPointBitmapLayout	bitmapLayout,
	[in] ::com::sun::星／主役にする::geometry::IntegerPoint2D	pos )
raises(	::com::sun::星／主役にする::lang::IndexOutOfBoundsException, VolatileContentDestroyedException );

Description

Get a 選び出す／独身 pixel of the bitmap, returning its color value.

公式文書，認める that the bitmap memory layout might change for volatile bitmaps.

Parameter bitmapLayout

The memory layout the returned data is in.

Parameter pos

A position, within the bounds of the bitmap, to retrieve the color from.

Throws

VolatileContentDestroyedException if the bitmap is volatile, and the content has been destroyed by the system.

Throws

com::sun::星／主役にする::lang::IndexOutOfBoundsException if the given position is outside the permissible bitmap area.

getMemoryLayout

FloatingPointBitmapLayout
getMemoryLayout();

Description

Query the memory layout for this bitmap.

Please 公式文書，認める that for volatile bitmaps, the memory layout might change between その後の calls.
