NAME
glFramebufferParameteri - set a named parameter of a framebuffer
C SPECIFICATION
void glFramebufferParameteri(GLenum target, GLenum pname, GLint param);
PARAMETERS
target
The target of the operation, which must be GL_READ_FRAMEBUFFER,
GL_DRAW_FRAMEBUFFER or GL_FRAMEBUFFER.
pname
A token indicating the parameter to be modified.
param
The new value for the parameter named pname.
DESCRIPTION
glFramebufferParameteri modifies the current value of the parameter
named pname in the framebuffer bound to target. target must be
GL_READ_FRAMEBFUFFER, GL_DRAW_FRAMEBUFFER or GL_FRAMEBUFFER. The token
GL_FRAMEBUFFER is treated as GL_DRAW_FRAMEBUFFER. A non-default
framebuffer must be bound to target.
pname specifies the parameter to be modified. The following symbols are
accepted in pname:
GL_FRAMEBUFFER_DEFAULT_WIDTH
param specifies the assumed with for a framebuffer object with no
attachments. If a framebuffer has attachments then the width of
those attachments is used, otherwise the value of
GL_FRAMEBUFFER_DEFAULT_WIDTH is used for the framebuffer. param
must be greater than or equal to zero and less than or equal to the
value of GL_MAX_FRAMEBUFFER_WIDTH.
GL_FRAMEBUFFER_DEFAULT_HEIGHT
param specifies the assumed height for a framebuffer object with no
attachments. If a framebuffer has attachments then the height of
those attachments is used, otherwise the value of
GL_FRAMEBUFFER_DEFAULT_HEIGHT is used for the framebuffer. param
must be greater than or equal to zero and less than or equal to the
value of GL_MAX_FRAMEBUFFER_HEIGHT.
GL_FRAMEBUFFER_DEFAULT_LAYERS
param specifies the assumed number of layers for a framebuffer
object with no attachments. If a framebuffer has attachments then
the layer count of those attachments is used, otherwise the value
of GL_FRAMEBUFFER_DEFAULT_LAYERS is used for the framebuffer.
param must be greater than or equal to zero and less than or equal
to the value of GL_MAX_FRAMEBUFFER_LAYERS.
GL_FRAMEBUFFER_DEFAULT_SAMPLES
param specifies the assumed number of samples in a framebuffer
object with no attachments. If a framebuffer has attachments then
the sample count of those attachments is used, otherwise the value
of GL_FRAMEBUFFER_DEFAULT_SAMPLES is used for the framebuffer.
param must be greater than or equal to zero and less than or equal
to the value of GL_MAX_FRAMEBUFFER_SAMPLE.
GL_FRAMEBUFFER_DEFAULT_FIXED_SAMPLE_LOCATIONS
param specifies whether the framebuffer should assume identical
sample locations and the same number of samples for all texels in
the virtual image. If param is zero, then the implementation may
vary the position or the count of samples within the virtual image
from pixel to pixel, otherwise it will use the same sample position
and count for all pixels in the virtual image.
ERRORS
GL_INVALID_ENUM is generated if target is not one of the accepted
framebuffer targets.
GL_INVAILD_VALUE is generated if pname is GL_FRAMEBUFFER_DEFAULT_WIDTH
and param is less than zero or greater than the value of
GL_MAX_FRAMEBUFFER_WIDTH.
GL_INVAILD_VALUE is generated if pname is GL_FRAMEBUFFER_DEFAULT_HEIGHT
and param is less than zero or greater than the value of
GL_MAX_FRAMEBUFFER_HEIGHT.
GL_INVAILD_VALUE is generated if pname is GL_FRAMEBUFFER_DEFAULT_LAYERS
and param is less than zero or greater than the value of
GL_MAX_FRAMEBUFFER_LAYERS.
GL_INVAILD_VALUE is generated if pname is
GL_FRAMEBUFFER_DEFAULT_SAMPLES and param is less than zero or greater
than the value of GL_MAX_FRAMEBUFFER_SAMPLES.
GL_INVALID_OPERATION is generated if the default framebuffer is bound
to target.
