Detailed Description

Holds parameters for setting glTexParameteri variables. <visibility=local>

Synopsis

Holds parameters for setting glTexParameteri variables. See the man page for glTexParameteri for description. This class is not needed unless the caller wishes to change the defaults for a textured image. maxtexturesize is used to specify the maximum texture size used for an image. The value used will be the smallest power of 2 that is >= maxtexturesize. By default, the display hosts' maximum texture size will be used. Again, this isn't normally changed. GLPCTextureParams may be deleted after GLPCTexturedImage is created.

void casa::GLPCTextureParams::maxTextureSize

(

GLint

maxtexturesize

)

Set value to use for max texture size.

Value will be rounded up to a power of 2 >= maxTextureSize.

void casa::GLPCTextureParams::wrap	(	GLint	wrapS,
		GLint	wrapT = 0
	)

Set wrap parameters.

If wrapT is 0, use wrapS.
