Take out your modified code sections, and tell me where to put them. If people sent the whole thing, I would have many different versions, but no idea how to combine them all. // //**************************************************************** // // Created by Gonetz, 2007 // //**************************************************************** static inline void mirror32bS(uint8_t *tex, uint8_t *start, int width, int height, int mask, int line, int full, int count) { uint32_t *v8; int v9; int v10; v8 = (uint32_t *)start; v9 = height; do { v10 = 0; do { if ( width & (v10 + width) ) { *v8 = *(uint32_t *)(&tex[mask] - (mask & 4 * v10)); ++v8; } else { *v8 = *(uint32_t *)&tex[mask & 4 * v10]; ++v8; } ++v10; } while ( v10 != count ); v8 = (uint32_t *)((char *)v8 + line); tex += full; --v9; } while ( v9 ); } static inline void wrap32bS(uint8_t *tex, uint8_t *start, int height, int mask, int line, int full, int count) { uint32_t *v7; int v8; int v9; v7 = (uint32_t *)start; v8 = height; do { v9 = 0; do { *v7 = *(uint32_t *)&tex[4 * (mask & v9)]; ++v7; ++v9; } while ( v9 != count ); v7 = (uint32_t *)((char *)v7 + line); tex += full; --v8; } while ( v8 ); } static inline void clamp32bS(uint8_t *tex, uint8_t *constant, int height, int line, int full, int count) { uint32_t *v6; uint32_t *v7; int v8; uint32_t v9; int v10; v6 = (uint32_t *)constant; v7 = (uint32_t *)tex; v8 = height; do { v9 = *v6; v10 = count; do { *v7 = v9; ++v7; --v10; } while ( v10 ); v6 = (uint32_t *)((char *)v6 + full); v7 = (uint32_t *)((char *)v7 + line); --v8; } while ( v8 ); } //**************************************************************** // 32-bit Horizontal Mirror void Mirror32bS (unsigned char * tex, uint32_t mask, uint32_t max_width, uint32_t real_width, uint32_t height) { if (mask == 0) return; uint32_t mask_width = (1 << mask); uint32_t mask_mask = (mask_width-1) << 2; if (mask_width >= max_width) return; int count = max_width - mask_width; if (count <= 0) return; int line_full = real_width << 2; int line = line_full - (count << 2); if (line < 0) return; unsigned char * start = tex + (mask_width << 2); mirror32bS (tex, start, mask_width, height, mask_mask, line, line_full, count); } //**************************************************************** // 32-bit Horizontal Wrap void Wrap32bS (unsigned char * tex, uint32_t mask, uint32_t max_width, uint32_t real_width, uint32_t height) { if (mask == 0) return; uint32_t mask_width = (1 << mask); uint32_t mask_mask = (mask_width-1); if (mask_width >= max_width) return; int count = (max_width - mask_width); if (count <= 0) return; int line_full = real_width << 2; int line = line_full - (count << 2); if (line < 0) return; unsigned char * start = tex + (mask_width << 2); wrap32bS (tex, start, height, mask_mask, line, line_full, count); } //**************************************************************** // 32-bit Horizontal Clamp void Clamp32bS (unsigned char * tex, uint32_t width, uint32_t clamp_to, uint32_t real_width, uint32_t real_height) { if (real_width <= width) return; unsigned char *dest = tex + (width << 2); unsigned char *constant = dest-4; int count = clamp_to - width; int line_full = real_width << 2; int line = width << 2; clamp32bS (dest, constant, real_height, line, line_full, count); } //**************************************************************** // 32-bit Vertical Mirror void Mirror32bT (unsigned char * tex, uint32_t mask, uint32_t max_height, uint32_t real_width) { if (mask == 0) return; uint32_t mask_height = (1 << mask); uint32_t mask_mask = mask_height-1; if (max_height <= mask_height) return; int line_full = real_width << 2; unsigned char *dst = tex + mask_height * line_full; for (uint32_t y=mask_height; y>2)), (line_full>>2)); dst += line_full; } } //**************************************************************** // 32-bit Vertical Clamp void Clamp32bT (unsigned char * tex, uint32_t height, uint32_t real_width, uint32_t clamp_to) { int line_full = real_width << 2; unsigned char *dst = tex + height * line_full; unsigned char *const_line = dst - line_full; for (uint32_t y=height; y
