Re: [ab] Using lispbuilder with cl-opengl

Of course, messing around with pixel formats wouldn't be at all necessary if convert-image works properly with GL windows... Does it? On Sun, Jul 12, 2009 at 12:39 AM, Elliott Slaughter < elliottslaugh...@gmail.com> wrote: > Another question along the lines of my first question: > > A lot of the

Re: [ab] Using lispbuilder with cl-opengl

Another question along the lines of my first question: A lot of the C++ tutorials have code to deal with the pixel format and bit depth of surfaces loaded from files [1]. For example, surface->format->BytesPerPixel might be used to get the bit depth, or surface->format->Rmask might be used to
