References copy2screen(), and tgraphmodeparameters::directscreenaccess.

void copySurface2screen (  void   ) 
 

when using SDL, all operations are not performed on the displaymemory itself (as is the case with DOS), but on a buffer.

This function copies the buffer to the screen, performing a color conversion if necessary

Definition at line 1379 of file basegfx.cpp.

void ellipse (  int  x1,
int  y1,
int  x2,
int  y2,
int  color,
float  tolerance
) 
 

paints an ellipse on the screen that fills the rectangle x1/y1 - x2/y2.

The thickness of the ellipse depends on tolerance. This function is just for highlighting elements on the screen, not for drawing nice and mathematically correct ellipse

Definition at line 1214 of file basegfx.cpp.

References putpixel().

void flippict (  void *  s,
void *  d,
int  dir = 1
) 
 

mirrors a picture horizontally (dir=1) or vertically (dir=0).

d must point to a buffer with the size of imagesize2(s)

Definition at line 675 of file basegfx.cpp.

void generategrayxlattable (  ppixelxlattable  tab,
char  offset,
char  size,
dacpalette256 *  pal
) 
 

A translation table ( to be used by xlatpict ) is generated to translate any color of palette pal to its gray value.

The new pixels after the translation are still to be used with the palette pal. offset and size specify a range of colors that are assumed to be a linear transition from white to black. So all colors are mapped to one of the colors of the offset-size range.

void putxlatfilter (  int  x1,
int  y1,
void *  pictbuffer,
char *  xlattables
) 
 

puts the image in pictbuffer on the screen performing a color translation.

xlattables points to an array of n*256 byte. n must be equal or greater than the highest pixel in pictbuffer. Example: you want to paint the tracks on the screen which are left by heavy vehicles. There is an image of a track which contains just pixels of 0, 1 and two. You now provide a set of 3 tables each 256 bytes large. The first one just counts from 0 to 255 The second one has color values that are a bit darker than the original: If color #2 was blue, table[2] would have the index of a dark blue color. The third table is like the second one, but points to even darker colors. If you now paint the track using this function: where there is color #0 in the track image, the pixel on the screen would be unchanged where there is color #1 in the track image, the pixel on the screen is made darker and where there is color #2, the pixel on the screen is becoming even more darker Ok, that's all. A very specialized function. I just checked and noticed that it is not used any more by ASC. Damn, why did I write this description instead of just deleting this procedure ;-)
