Detailed Description

The PySide.QtOpenGL.QGLFramebufferObjectFormat class specifies the format of an OpenGL framebuffer object.

A framebuffer object has several characteristics:

Note that the desired attachments or number of samples per pixels might not be supported by the hardware driver. Call QGLFramebufferObject.format() after creating a PySide.QtOpenGL.QGLFramebufferObject to find the exact format that was used to create the frame buffer object.

class PySide.QtOpenGL.QGLFramebufferObjectFormat
class PySide.QtOpenGL.QGLFramebufferObjectFormat(other)
Parameters:otherPySide.QtOpenGL.QGLFramebufferObjectFormat

Creates a PySide.QtOpenGL.QGLFramebufferObjectFormat object for specifying the format of an OpenGL framebuffer object.

By default the format specifies a non-multisample framebuffer object with no attachments, texture target GL_TEXTURE_2D , and internal format GL_RGBA8 . On OpenGL/ES systems, the default internal format is GL_RGBA .

Constructs a copy of other .

PySide.QtOpenGL.QGLFramebufferObjectFormat.attachment()
Return type:PySide.QtOpenGL.QGLFramebufferObject.Attachment

Returns the configuration of the depth and stencil buffers attached to a framebuffer object. The default is QGLFramebufferObject.NoAttachment .

PySide.QtOpenGL.QGLFramebufferObjectFormat.internalTextureFormat()
Return type:PySide.QtOpenGL.GLenum

Returns the internal format of a framebuffer object’s texture or multisample framebuffer object’s color buffer. The default is GL_RGBA8 on desktop OpenGL systems, and GL_RGBA on OpenGL/ES systems.

PySide.QtOpenGL.QGLFramebufferObjectFormat.__ne__(other)
Parameters:otherPySide.QtOpenGL.QGLFramebufferObjectFormat
Return type:PySide.QtCore.bool

Returns false if all the options of this framebuffer object format are the same as other ; otherwise returns true.

PySide.QtOpenGL.QGLFramebufferObjectFormat.__eq__(other)
Parameters:otherPySide.QtOpenGL.QGLFramebufferObjectFormat
Return type:PySide.QtCore.bool

Returns true if all the options of this framebuffer object format are the same as other ; otherwise returns false.

PySide.QtOpenGL.QGLFramebufferObjectFormat.samples()
Return type:PySide.QtCore.int

Returns the number of samples per pixel if a framebuffer object is a multisample framebuffer object. Otherwise, returns 0. The default value is 0.

PySide.QtOpenGL.QGLFramebufferObjectFormat.setAttachment(attachment)
Parameters:attachmentPySide.QtOpenGL.QGLFramebufferObject.Attachment
PySide.QtOpenGL.QGLFramebufferObjectFormat.setInternalTextureFormat(internalTextureFormat)
Parameters:internalTextureFormatPySide.QtOpenGL.GLenum

Sets the internal format of a framebuffer object’s texture or multisample framebuffer object’s color buffer to internalTextureFormat .

PySide.QtOpenGL.QGLFramebufferObjectFormat.setSamples(samples)
Parameters:samplesPySide.QtCore.int

Sets the number of samples per pixel for a multisample framebuffer object to samples . The default sample count of 0 represents a regular non-multisample framebuffer object.

If the desired amount of samples per pixel is not supported by the hardware then the maximum number of samples per pixel will be used. Note that multisample framebuffer objects can not be bound as textures. Also, the GL_EXT_framebuffer_multisample extension is required to create a framebuffer with more than one sample per pixel.

PySide.QtOpenGL.QGLFramebufferObjectFormat.setTextureTarget(target)
Parameters:targetPySide.QtOpenGL.GLenum

Sets the texture target of the texture attached to a framebuffer object to target . Ignored for multisample framebuffer objects.

PySide.QtOpenGL.QGLFramebufferObjectFormat.textureTarget()
Return type:PySide.QtOpenGL.GLenum

Returns the texture target of the texture attached to a framebuffer object. Ignored for multisample framebuffer objects. The default is GL_TEXTURE_2D .
