Image Scaling

/prog/, do you have fast and good image scaling algorithm in the form of:
void resample(uint8_t *Dst, int DstW, int DstH, uint8_t *Src, int SrcW, int SrcH);

???

first you have to convert ints to float for multiplication, then convert them back for memory addressing. float format is very different from int format, so conversion will take forever
