14 \section intro_sec Introduction
+
15 
+
16 The SDL2_gfx library provides the basic drawing functions such as lines,
+
17 circles or polygons provided by SDL_gfx on SDL2 against renderers of SDL2.
+
18 
+
19 The current components of the SDL2_gfx library are:
+
20 - Graphic Primitives (SDL2_gfxPrimitives.h, SDL2_gfxPrimitives.c)
+
21 - Surface Rotozoomer (SDL2_rotozoom.h, SDL2_rotozoom.c)
+
22 - Framerate control (SDL2_framerate.h, SDL2_framerate.c)
+
23 - MMX image filters (SDL2_imageFilter.h, SDL2_imageFilter.c)
+
24 - Build-in 8x8 Font (SDL2_gfxPrimitives_font.h)
+
25 
+
26 Note that SDL2_gfx is compatible with SDL version 2.0 (not SDL 1.2).
+
27 
+
28 \section install_sec Installation
+
29 
+
30 \subsection unix Unix/Linux
+
31 
+
32 Use the standard autoconf/automake sequence to compile and install the library.
+
33 \verbatim
+
34  ./autogen.sh # (optional, recommended)
+
35  ./configure
+
36  make
+
37  make install
+
38 \endverbatim
+
39 
+
40 \\subsubsection nommx Linker Configuration
+
41 
+
42 The default location for the installation is /usr/local/lib and /usr/local/include.
+
43 This libary path may need to be added to the file the linker configuration file:
+
44 \verbatim
+
45  vi /etc/ld.so.conf
+
46  ldconfig
+
47 \endverbatim
+
48 
+
49 \\subsubsection nommx Non-MMX Platforms
+
50 
+
51 To build without MMX code enabled (i.e. ARM, PPC, AMD64 architectures):
+
52 \verbatim
+
53  ./configure --disable-mmx
+
54  make
+
55  make install
+
56 \endverbatim
+
57 
+
58 \subsection visualstudio Windows (VS2012, VS2013)
+
59 
+
60 Open the SDL2_gfx.sln solution file, right click on the solution and choose 'Rebuild'.
+
61 
+
62 The SDL2 Visual Studio solution must be placed in a directory alongside SDL2_gfx and build in the same configuration, i.e. Debug or Release, beforehand so the referenced SDL2.lib file can be found.
+
63 
+
64 \subsection platformosx Mac OSX
+
65 
+
66 The usual autotools build chain should be used. MacPorts or fink may be required.
+
67 
+
68 Xcode is supported via templates. See Xcode.zip - this template only supports SDL2_gfx
+
69 and not the tests. For this template, the Deployment Target (the lowest version to run on)
+
70 is set to 10.11 and expects the SDL2.framework preinstalled in the default location: /Library/Frameworks.
+
71 
+
72 \section test_sec Test Programs
+
73 
+
74 Change to the ./test directory and run
+
75 \verbatim
+
76  ./autogen.sh
+
77  ./configure
+
78  make
+
79 \endverbatim
+
80 to create several test programs for the libraries functions. This requires
+
81 the SDL2_gfx library to be previously compiled and installed.
+
82 
+
83 See the source in the test/*.c files for some sample code and implementation hints.
+
84 
+
85 \section documentation_sec Documentation

Uint32 SDL_framerateDelay (FPSmanager * manager)
+
+ +

Delay execution to maintain a constant framerate and calculate fps.

+

Generate a delay to accomodate currently set framerate. Call once in the graphics/rendering loop. If the computer cannot keep up with the rate (i.e. drawing too slow), the delay is zero and the delay interpolation is reset.

+
Parameters
+ + +

int draw_endpoint 
)
+
+ +

Internal function to draw anti-aliased line with alpha blending and endpoint control.

+

This implementation of the Wu antialiasing code is based on Mike Abrash's DDJ article which was reprinted as Chapter 42 of his Graphics Programming Black Book, but has been optimized to work with SDL and utilizes 32-bit fixed-point arithmetic by A. Schiffler. The endpoint control allows the supression to draw the last pixel useful for rendering continous aa-lines with alpha<255.

+
Parameters
+ + + + + + + + + + + +
rendererThe renderer to draw on.
x1X coordinate of the first point of the aa-line.
y1Y coordinate of the first point of the aa-line.
x2X coordinate of the second point of the aa-line.
y2Y coordinate of the second point of the aa-line.
rThe red value of the aa-line to draw.
gThe green value of the aa-line to draw.
bThe blue value of the aa-line to draw.
aThe alpha value of the aa-line to draw.
draw_endpointFlag indicating if the endpoint should be drawn; draw if non-zero.
+
+
+
Returns
Returns 0 on success, -1 on failure.

#define GUARD_ROWS   (2)
+
+ +

Number of guard rows added to destination surfaces.

+

This is a simple but effective workaround for observed issues. These rows allocate extra memory and are then hidden from the surface. Rows are added to the end of destination surfaces when they are allocated. This catches any potential overflows which seem to happen with just the right src image dimensions and scale/rotation and can lead to a situation where the program can segfault.

int numClockwiseTurns 
)
+
+ +

Rotates a 8/16/24/32 bit surface in increments of 90 degrees.

+

Specialized 90 degree rotator which rotates a 'src' surface in 90 degree increments clockwise returning a new surface. Faster than rotozoomer since no scanning or interpolation takes place. Input surface must be 8/16/24/32 bit. (code contributed by J. Schiller, improved by C. Allport and A. Schiffler)

+
Parameters
+ + + +
srcSource surface to rotate.
numClockwiseTurnsNumber of clockwise 90 degree turns to apply to the source.
+
+
+
Returns
The new, rotated surface; or NULL for surfaces with incorrect input format.

SDL_Surface* shrinkSurface (SDL_Surface * src,
int factorx,
int factory 
)
+
+ +

Shrink a surface by an integer ratio using averaging.

+

Shrinks a 32bit or 8bit 'src' surface to a newly created 'dst' surface. 'factorx' and 'factory' are the shrinking ratios (i.e. 2=1/2 the size, 3=1/3 the size, etc.) The destination surface is antialiased by averaging the source box RGBA or Y information. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly. The input surface is not modified. The output surface is newly allocated.

+
Parameters
+ + + + +
srcThe surface to shrink.
factorxThe horizontal shrinking ratio.
factoryThe vertical shrinking ratio.
+
+
+
Returns
The new, shrunken surface.

SDL2_ROTOZOOM_SCOPE SDL_Surface* rotateSurface90Degrees (SDL_Surface * src,
int numClockwiseTurns 
)
+
+ +

Rotates a 8/16/24/32 bit surface in increments of 90 degrees.

+

Specialized 90 degree rotator which rotates a 'src' surface in 90 degree increments clockwise returning a new surface. Faster than rotozoomer since no scanning or interpolation takes place. Input surface must be 8/16/24/32 bit. (code contributed by J. Schiller, improved by C. Allport and A. Schiffler)

+
Parameters
+ + + +
srcSource surface to rotate.
numClockwiseTurnsNumber of clockwise 90 degree turns to apply to the source.
+
+
+
Returns
The new, rotated surface; or NULL for surfaces with incorrect input format.
+ +

SDL2_ROTOZOOM_SCOPE SDL_Surface* rotozoomSurface (SDL_Surface * src,
double angle,
double zoom,
int smooth 
)
+
+ +

Rotates and zooms a surface and optional anti-aliasing.

+

Rotates and zoomes a 32bit or 8bit 'src' surface to newly created 'dst' surface. 'angle' is the rotation in degrees and 'zoom' a scaling factor. If 'smooth' is set then the destination 32bit surface is anti-aliased. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly.

+
Parameters
+ + + + + +
srcThe surface to rotozoom.
angleThe angle to rotate in degrees.
zoomThe scaling factor.
smoothAntialiasing flag; set to SMOOTHING_ON to enable.
+
+
+
Returns
The new rotozoomed surface.

SDL2_ROTOZOOM_SCOPE SDL_Surface* rotozoomSurfaceXY (SDL_Surface * src,
double angle,
double zoomx,
double zoomy,
int smooth 
)
+
+ +

Rotates and zooms a surface with different horizontal and vertival scaling factors and optional anti-aliasing.

+

Rotates and zooms a 32bit or 8bit 'src' surface to newly created 'dst' surface. 'angle' is the rotation in degrees, 'zoomx and 'zoomy' scaling factors. If 'smooth' is set then the destination 32bit surface is anti-aliased. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly.

+
Parameters
+ + + + + + +
srcThe surface to rotozoom.
angleThe angle to rotate in degrees.
zoomxThe horizontal scaling factor.
zoomyThe vertical scaling factor.

SDL2_ROTOZOOM_SCOPE SDL_Surface* shrinkSurface (SDL_Surface * src,
int factorx,
int factory 
)
+
+ +

Shrink a surface by an integer ratio using averaging.

+

Shrinks a 32bit or 8bit 'src' surface to a newly created 'dst' surface. 'factorx' and 'factory' are the shrinking ratios (i.e. 2=1/2 the size, 3=1/3 the size, etc.) The destination surface is antialiased by averaging the source box RGBA or Y information. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly. The input surface is not modified. The output surface is newly allocated.

+
Parameters
+ + + + +
srcThe surface to shrink.
factorxThe horizontal shrinking ratio.
factoryThe vertical shrinking ratio.
+
+
+
Returns
The new, shrunken surface.

SDL2_ROTOZOOM_SCOPE SDL_Surface* zoomSurface (SDL_Surface * src,
double zoomx,
double zoomy,
int smooth 
)
+
+ +

Zoom a surface by independent horizontal and vertical factors with optional smoothing.

+

Zooms a 32bit or 8bit 'src' surface to newly created 'dst' surface. 'zoomx' and 'zoomy' are scaling factors for width and height. If 'smooth' is on then the destination 32bit surface is anti-aliased. If the surface is not 8bit or 32bit RGBA/ABGR it will be converted into a 32bit RGBA format on the fly. If zoom factors are negative, the image is flipped on the axes.

+
Parameters
+ + + + + +
srcThe surface to zoom.
zoomxThe horizontal zoom factor.
zoomyThe vertical zoom factor.
smoothAntialiasing flag; set to SMOOTHING_ON to enable.
+
+
+
Returns
The new, zoomed surface.
