The buffers parameter should be a mask consisting of any combination of , and specifies whether linear or nearest interpolation should be used when scaling is performed.

If source equals target a copy is performed within the same buffer.

blit Framebuffer(QOpen GLFramebuffer Object *target, const QRect &target Rect, QOpen GLFramebuffer Object *source, const QRect &source Rect, GLbitfield buffers, GLenum filter, int read Color Attachment Index, int draw Color Attachment Index, Framebuffer Restore Policy restore Policy)blit Framebuffer(QOpen GLFramebuffer Object *target, const QRect &target Rect, QOpen GLFramebuffer Object *source, const QRect &source Rect, GLbitfield buffers, GLenum filter, int read Color Attachment Index, int draw Color Attachment Index)blit Framebuffer(QOpen GLFramebuffer Object *target, const QRect &target Rect, QOpen GLFramebuffer Object *source, const QRect &source Rect, GLbitfield buffers = GL_COLOR_BUFFER_BIT, GLenum filter = GL_NEAREST) extension.

It provides a rendering surface that can be painted on with a QPainter with the help of QOpen GLPaint Device, or rendered to using native Open GL calls.

Some drivers may not be fully conformant in this respect, however. When internal Format is not , it specifies the internal format of the texture or renderbuffer.

By default, no depth and stencil buffers are attached. Constructs an Open GL framebuffer object and binds a texture to the buffer of the given width and height. Destroys the framebuffer object and frees any allocated resources.

Note that you need to create a QOpen GLFramebuffer Object with more than one sample per pixel for primitives to be antialiased when drawing using a QPainter.

To create a multisample framebuffer object you should use one of the constructors that take a QOpen GLFramebuffer Object Format parameter, and set the QOpen GLFramebuffer Object Format::samples() property to a non-zero value.

For multisample framebuffer objects a color render buffer is created, otherwise a texture with the specified texture target is created.

The color render buffer or texture will have the specified internal format, and will be bound to the attachment in the framebuffer object.
