PixelFormat

Cesium.PixelFormat 枚举类型定义了一个像素的格式。该类型主要用于纹理创建和读取像素数据。

Members

DEPTH_COMPONENT

深度值,24 位或 32 位。

DEPTH_STENCIL

深度和模板缓冲值,32 位。

RGB

RGB 值,8 位每个分量。

RGBA

RGBA 值,8 位每个分量。

LUMINANCE

亮度值,8 位。

ALPHA

Alpha 值为 8 位。

LUMINANCE_ALPHA

8 位亮度值和 8 位 alpha 值。

RGB_DXT1

RGB 值,压缩为 DXT1 格式,仅有 4 位/像素。

RGBA_DXT1

RGB 值和 1 位 alpha 值,压缩为 DXT1 格式,仅有 4 位/像素。

RGBA_DXT3

RGB 值和 4 位 alpha 值,压缩为 DXT3 格式,仅有 8 位/像素。

RGBA_DXT5

RGB 值和 8 位 alpha 值,压缩为 DXT5 格式,仅有 8 位/像素。

SIGNED_INT8

带符号的 8 位整数。

SIGNED_INT16

带符号的 16 位整数。

SIGNED_INT32

带符号的 32 位整数。

UNSIGNED_INT8

无符号 8 位整数。

Examples

在下面的示例中,我们使用 Cesium.PixelFormat 枚举类型来创建一个 RGBA 类型的纹理,像素大小为 256 x 256:

var texture = new Cesium.Texture({
    context : scene.context,
    width   : 256,
    height  : 256,
    pixelFormat : Cesium.PixelFormat.RGBA,
    pixelDatatype : Cesium.PixelDatatype.UNSIGNED_BYTE
});
