Name

eglSurfaceAttrib — + set an EGL surface attribute +

C Specification

+ + + + + + + + + + + + + + + + + +

+ `EGLBoolean eglSurfaceAttrib(` +	EGLDisplay `display`,
	EGLSurface `surface`,
	EGLint `attribute`,
	EGLint `value)`;

Parameters

+ + + display + + +: +
+ Specifies the EGL display connection. +
+
+ + + surface + + +: +
+ Specifies the EGL surface. +
+
+ + + attribute + + +: +
+ Specifies the EGL surface attribute to set. +
+
+ + + value + + +: +
+ Specifies the attributes required value. +
+

Description

+ eglSurfaceAttrib sets the value of + attribute for + surface to + value. + attribute can be one of the + following: +

+ + EGL_MIPMAP_LEVEL + +

+ For mipmap textures, the + EGL_MIPMAP_LEVEL attribute + indicates which level of the mipmap should be + rendered. If the value of this attribute is outside + the range of supported mipmap levels, the closest + valid mipmap level is selected for rendering. The + default value is 0. +

+ + EGL_MULTISAMPLE_RESOLVE + +

+ Specifies the filter to use when resolving the + multisample buffer (this may occur when swapping or + copying the surface, or when changing the client API + context bound to the surface). A + value of + EGL_MULTISAMPLE_RESOLVE_DEFAULT + chooses the default implementation-defined filtering + method, while + EGL_MULTISAMPLE_RESOLVE_BOX + chooses a one-pixel wide box filter placing equal + weighting on all multisample values. +

+ The initial value of + EGL_MULTISAMPLE_RESOLVE is + EGL_MULTISAMPLE_RESOLVE_DEFAULT. +

+ + EGL_SWAP_BEHAVIOR + +

+ Specifies the effect on the color buffer of posting + a surface with + eglSwapBuffers. + A value of + EGL_BUFFER_PRESERVED indicates + that color buffer contents are unaffected, while + EGL_BUFFER_DESTROYED indicates + that color buffer contents may be destroyed or + changed by the operation. +

+ The initial value of + EGL_SWAP_BEHAVIOR is chosen by + the implementation. +

Notes

+ Attribute EGL_MULTISAMPLE_RESOLVE is + supported only if the EGL version is 1.4 or greater. +

+ Attribute EGL_SWAP_BEHAVIOR is + supported only if the EGL version is 1.2 or greater. +

+ If the value of pbuffer attribute + EGL_TEXTURE_FORMAT is + EGL_NO_TEXTURE, the value of attribute + EGL_TEXTURE_TARGET is + EGL_NO_TEXTURE, or + surface is not a pbuffer, then + attribute EGL_MIPMAP_LEVEL may be set, + but has no effect. +

Errors

+ EGL_FALSE is returned on failure, + EGL_TRUE otherwise. +

+ EGL_BAD_DISPLAY is generated if + display is not an EGL display connection. +

+ EGL_BAD_MATCH is generated if + attribute is + EGL_MULTISAMPLE_RESOLVE, + value is + EGL_MULTISAMPLE_RESOLVE_BOX, and the + EGL_SURFACE_TYPE attribute of the + EGLConfig used to create + surface does not contain + EGL_MULTISAMPLE_RESOLVE_BOX_BIT. +

+ EGL_BAD_MATCH is generated if + attribute is + EGL_SWAP_BEHAVIOR, + value is + EGL_BUFFER_PRESERVED, and the + EGL_SURFACE_TYPE attribute of the + EGLConfig used to create + surface does not contain + EGL_SWAP_BEHAVIOR_PRESERVED_BIT. +

+ EGL_NOT_INITIALIZED is generated if + display has not been initialized. +

+ EGL_BAD_SURFACE is generated if + surface is not an EGL surface. +

+ EGL_BAD_ATTRIBUTE is generated if + attribute is not a valid surface attribute. +
