Date: Mon, 16 Feb 2004 19:21:51 +0100 From: Max Horn Subject: Re: Fix for OSX bug The problem is that our actual client area is realized as a subview of the "content view" of the window. That's normal so far. The odd part is that, while our subview starts out filling it parent 100%, upon resizes it gets changed to something smaller.... Anyway, here is a revised patch which simply enforces the size of window_view by calling setFrameSize.

.TH "SDL_MapRGB" "3" "Tue 11 Sep 2001, 23:01" "SDL" "SDL API Reference" 
.SH "NAME"
SDL_MapRGB\- Map a RGB color value to a pixel format\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBUint32 \fBSDL_MapRGB\fP\fR(\fBSDL_PixelFormat *fmt, Uint8 r, Uint8 g, Uint8 b\fR);
.SH "DESCRIPTION"
.PP
Maps the RGB color value to the specified pixel format and returns the pixel value as a 32-bit int\&.
.PP
If the format has a palette (8-bit) the index of the closest matching color in the palette will be returned\&.
.PP
If the specified pixel format has an alpha component it will be returned as all 1 bits (fully opaque)\&.
.SH "RETURN VALUE"
.PP
A pixel value best approximating the given RGB color value for a given pixel format\&. If the pixel format bpp (color depth) is less than 32-bpp then the unused upper bits of the return value can safely be ignored (e\&.g\&., with a 16-bpp format the return value can be assigned to a \fBUint16\fP, and similarly a \fBUint8\fP for an 8-bpp format)\&.
