Cannot Call On Opengl Surfaces
It's not actually a problem with transparency, but in the setting of transparency for the windows. When a Surface is locked the pixel memory becomes available to access by regular software. pygame.display.set_gamma()¶ Change the hardware gamma ramps set_gamma(red, green=None, blue=None) -> bool Set the red, green, and blue gamma values on the display hardware. It allows only a portion of the screen to updated, instead of the entire area. http://electrictricycle.net/cannot-call/cannot-call-getoutputstream-after-a-call-to-getprintwriter.html
If not given, the entire surface will be copied. `special_flags` : int Optional blend operation; one of BLEND_ADD, BLEND_SUB, BLEND_MULT, BLEND_MIN, BLEND_MAX. :rtype: Rect :return: the actual area blitted. :note: `special_flags` It will be slightly different from SPG (it's a package now and not just a module anymore because the bigger number of features supported than SPG), but will include all widgets Returns the parent Surface of a subsurface. They will be stripped if the original had them.
up vote 1 down vote favorite I just turned on the pygame.OPENGL flag in my set_mode out of curiosity. If a new display mode is set, the existing Surface will automatically switch to operate on the new display. The return value will be an empty list if no display modes are available with the given arguments. I'm lookin for people who wants to collaborate to complete it, or for people who want to give an help to write a full documentation.
Lentvorski, Jr." References: [pygame] Cannot blit to an OpenGL surface From: "Andrew P. Looking forward to SPG2.September 8, 2008 10:22am - Canio Massimo Tristano - nickname: (keebus)Actually your issue is pretty wierd. It is also possible to subsurface the display Surface if the display mode is not hardware accelerated. If you are using a different type of display mode, it will simply update the entire contents of the surface.
The project is in early development and it will take a while until I manage to complete all the tasks I prefixed. Where in the analytic hierarchy is the theory of true set theory? It is safe to nest locking and unlocking calls. browse this site I don't NEED OpenGL, but I'm kind of curious about it.
The new Surface will have the same pixel formats, color palettes, and transparency settings as the original. :rtype: `Surface` ''' surf = self._surf self._prep() newsurf = SDL_ConvertSurface(surf, surf.format, surf.flags) self._unprep() return Most platforms will return a "window" key with the value set to the system id for the current display. The optional flags argument can be set to pygame.RLEACCEL to provide better performance on non accelerated displays. The color argument can be either an RGB sequence or a mapped color index. :Parameters: `color` : (int, int, int) or (int, int, int, int) or int Tuple of RGB(A) or
May everyone feel free to join the project!June 14, 2008 10:26am - Luca Fabbri - nickname: (keul)Yeah! The surface will only be unlocked after the final lock is released. ''' SDL_UnlockSurface(self._surf) if self._subsurface: self._unprep() def mustlock(self): '''Test if the surface requires locking. You can request special modules like hardware acceleration and OpenGL support. If passing a sequence of rectangles it is safe to include None values in the list, which will be skipped.
Pygame will emulate an unavailable color depth which can be slow. http://electrictricycle.net/cannot-call/cannot-call-non-interworking.html Returns the number of bits used to represent each pixel. Each feature is a bit in the flags bitmask. pygame.display.init()¶ Initialize the display module init() -> None Initializes the pygame display module.
Returns the parent Surface of a subsurface. The display module cannot do anything until it is initialized. The index should be a value from 0 to 255. :rtype: (int, int, int) ''' pal = self._surf.format.palette if not pal: raise pygame.base.error, 'Surface has no palette to get' if index http://electrictricycle.net/cannot-call/cannot-call-setfocus-within.html This value is different than the per pixel Surface alpha.
I'm looking for a lightweight and unobtrusive pygame/gui lib for a small prototype project of mine. Set the current color key for the Surface. This fix the problem for me too!June 14, 2008 6:06am - Elias - nickname: (biodome) - 4/5Thanks!
There are several to choose from, and you can even combine multiple types using the bitwise or operator, (the pipe "|" character).
When this option is enabled, this automatic stretching distorts the appearance of the pygame window. So, what should I use? Subsurfaces will also have a larger pitch than their real width. If a section of code is going to make calls that will repeatedly lock and unlock the Surface many times, it can be helpful to wrap the block inside a lock
The returned surface will still always match the requested resolution. An RLEACCEL Surface will be slower to modify, but quicker to blit as a source. :Parameters: `value` : int or None The alpha value, in range [0, 255]. See the Surface.lock() documentation for more details. http://electrictricycle.net/cannot-call/cannot-call-methods-on-int.html Here are the errors I encountered : pygame.error: Cannot blit to OPENGL Surfaces (OPENGLBLIT is ok) #when I try to blit on my surface pygame.error: Cannot call on OPENGL Surfaces #when
Surfaces in video memory are not always linearly packed. If only the width or height are set to 0, the Surface will have the same width or height as the screen resolution. In the end I'll put the possibility to skin windows, then it will be truly finished (for the features I decided for it). You can pass keyword argument values to this function.
The environment variable is checked when the pygame display is initialized. Otherwise depth, flags, and masks arguments can be used, similar to `__init__`. Otherwise, this argument is the depth, specified in bits per pixel. `flags` : int or None Otherwise, this argument is the flags for the new surface; a combination of SWSURFACE, HWSURFACE for pygame related questions, comments, and suggestions, please see help (lists, irc)
Anyone know what it is?
