This module provides classes for working with Framebuffers & Renderbuffers and their attachments. Attachments can be pyglet Texture objects, which allows easily accessing their data, saving to disk, etc. Renderbuffers can be used if you don't need to access their data at a later time. For example:: # Create two objects to use as attachments for our Framebuffer. color_buffer = pyglet.image.Texture.create(width, height, min_filter=GL_NEAREST, mag_filter=GL_NEAREST) depth_buffer = pyglet.image.buffer.Renderbuffer(width, height, GL_DEPTH_COMPONENT) # Create a framebuffer object, and attach the two buffers: framebuffer = pyglet.image.Framebuffer() framebuffer.attach_texture(color_buffer, attachment=GL_COLOR_ATTACHMENT0) framebuffer.attach_renderbuffer(depth_buffer, attachment=GL_DEPTH_ATTACHMENT) # Bind the Framebuffer, which sets it as the active render target: framebuffer.bind() See the OpenGL documentation for more information on valid attachment types and targets. ) annotationsN)GLintGLuintglBindFramebufferglBindRenderbufferglCheckFramebufferStatusglClear)glDeleteFramebuffersglDeleteRenderbuffersglFramebufferRenderbufferglFramebufferTexture)glFramebufferTextureLayerglGenFramebuffersglGenRenderbuffers glGetIntegerv)glRenderbufferStorage glRenderbufferStorageMultisample)GL_COLOR_ATTACHMENT0GL_MAX_COLOR_ATTACHMENTSGL_RENDERBUFFER)GL_FRAMEBUFFERGL_FRAMEBUFFER_COMPLETE$GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT)(GL_FRAMEBUFFER_INCOMPLETE_DIMENSIONS_EXT%GL_FRAMEBUFFER_INCOMPLETE_DRAW_BUFFER)%GL_FRAMEBUFFER_INCOMPLETE_FORMATS_EXT,GL_FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT)%GL_FRAMEBUFFER_INCOMPLETE_READ_BUFFERGL_FRAMEBUFFER_UNSUPPORTED) TYPE_CHECKING)TexturereturnintcVt}tt||jS)z4Get the maximum allow Framebuffer Color attachments.)rrrvalue)numbers N/home/agentuser/manim-venv/lib/python3.11/site-packages/pyglet/image/buffer.pyget_max_color_attachmentsr(*s$ WWF*F333 <ceZdZdZddd Zedd Zedd Zedd ZddZ e ddZ ddZ ddZ ddZdS) RenderbufferzOpenGL Renderbuffer Object.widthr#heightinternal_formatsamplesr"Nonecvtjj|_t |_||_||_||_td|jtt|j|dkrtt||||ntt|||ttddS)zCreate a RenderBuffer instance.r,rN)pygletglcurrent_context_contextr_id_width_height_internal_formatrrrrr)selfr-r.r/r0s r'__init__zRenderbuffer.__init__4s 1 88  /1dh'''?DH555 Q;; ,_gX]_e f f f f !/?E6 R R R?A.....r)c|jjSNr7r%r;s r'idzRenderbuffer.idFs x~r)c|jSr>r8r@s r'r-zRenderbuffer.widthJs {r)c|jSr>r9r@s r'r.zRenderbuffer.heightNs |r)c:tt|jdSr>)rrr7r@s r'bindzRenderbuffer.bindRs?DH55555r)c0ttddS)Nr)rrr)r'unbindzRenderbuffer.unbindUs?A.....r)c>td|jd|_dS)Nr,)r r7r@s r'deletezRenderbuffer.deleteYsa***r)c|jF |j|jjd|_dS#tt f$rYdSwxYwdSr>)r7r6delete_renderbufferr%AttributeError ImportErrorr@s r'__del__zRenderbuffer.__del__]sc 8   11$(.AAA"K0     +6A  A strc:|jjd|jjdSNz(id=) __class____name__r7r%r@s r'__repr__zRenderbuffer.__repr__e".)@@tx~@@@@r)N)r,) r-r#r.r#r/r#r0r#r"r1r"r#r"r1r"rS)rY __module__ __qualname____doc__r<propertyrAr-r.rG staticmethodrJrLrQrZrIr)r'r+r+1s %%/////$XXX6666///\/AAAAAAr)r+ceZdZdZefddZed dZed dZed d Z d!d Z d!d Z d!d Z d!d Z d!dZed"dZed#dZeefd$dZeefd%dZeefd&dZd#dZdS)' Framebufferz:OpenGL Framebuffer Object. .. versionadded:: 2.0 targetr#r"r1ctjj|_t |_t d|jd|_d|_d|_ ||_ dS)zCreate a Framebuffer Instance.r,rN) r3r4r5r6rr7r_attachment_typesr8r9rf)r;rfs r'r<zFramebuffer.__init__nsL 1 88!TX&&&!"   r)c|jjS)zThe Framebuffer id.r?r@s r'rAzFramebuffer.idxsx~r)c|jS)z#The width of the widest attachment.rCr@s r'r-zFramebuffer.width}s {r)c|jS)z%The height of the tallest attachment.rEr@s r'r.zFramebuffer.heights |r)c:t|j|jdS)zWBind the Framebuffer.
