Values

glColorspace → const EglSurfaceAttributes

Specifies the color space used by OpenGL and OpenGL ES when rendering to the surface. If its value is EGL_GL_COLORSPACE_SRGB, then a non-linear, perceptually uniform color space is assumed, with a corresponding GL_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING value of GL_SRGB. If its value is EGL_GL_COLORSPACE_LINEAR, then a linear color space is assumed, with a corresponding GL_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING value of GL_LINEAR. The default value of gl_colorspace is gl_colorspace_srgb. Note that the EGL_GL_COLORSPACE attribute is used only by OpenGL and OpenGL ES contexts supporting sRGB framebuffers. EGL itself does not distinguish multiple colorspace models. Refer to the ``sRGB Conversion'' sections of the OpenGL 4.6 and OpenGL ES 3.2 Specifications for more information.

height → const EglSurfaceAttributes

Specifies the required height of the pixel buffer surface. The default value is 0.

largestPbuffer → const EglSurfaceAttributes

Requests the largest available pixel buffer surface when the allocation would otherwise fail. Use eglQuerySurface to retrieve the dimensions of the allocated pixel buffer. The default value is EGL_FALSE.

mipmapTexture → const EglSurfaceAttributes

Specifies whether storage for mipmaps should be allocated. Space for mipmaps will be set aside if the attribute value is EGL_TRUE and EGL_TEXTURE_FORMAT is not EGL_NO_TEXTURE. The default value is EGL_FALSE.

textureFormat → const EglSurfaceAttributes

Specifies the format of the texture that will be created when a pbuffer is bound to a texture map. Possible values are EGL_NO_TEXTURE, EGL_TEXTURE_RGB, and EGL_TEXTURE_RGBA. The default value is EGL_NO_TEXTURE.

textureTarget → const EglSurfaceAttributes

Specifies the target for the texture that will be created when the pbuffer is created with a texture format of EGL_TEXTURE_RGB or EGL_TEXTURE_RGBA. Possible values are EGL_NO_TEXTURE, or EGL_TEXTURE_2D. The default value is EGL_NO_TEXTURE.

vgAlphaFormat → const EglSurfaceAttributes

Specifies how alpha values are interpreted by OpenVG when rendering to the surface. If its value is EGL_VG_ALPHA_FORMAT_NONPRE, then alpha values are not premultipled. If its value is EGL_VG_ALPHA_FORMAT_PRE, then alpha values are premultiplied. The default value of EGL_VG_ALPHA_FORMAT is EGL_VG_ALPHA_FORMAT_NONPRE.

vgColorspace → const EglSurfaceAttributes

Specifies the color space used by OpenVG when rendering to the surface. If its value is EGL_VG_COLORSPACE_sRGB, then a non-linear, perceptually uniform color space is assumed, with a corresponding VGImageFormat of form VG_s*. If its value is EGL_VG_COLORSPACE_LINEAR, then a linear color space is assumed, with a corresponding VGImageFormat of form VG_l*. The default value of EGL_VG_COLORSPACE is EGL_VG_COLORSPACE_sRGB.

width → const EglSurfaceAttributes

Specifies the required width of the pixel buffer surface. The default value is 0.
