psxdev libs - shared libraries

psxdev server library

• void psxdev_init (void);
  initialize the library.
• int psxdev_server (int dev, int sockin, int sockout);
  This is the complete file server and I/O redirection for caetla. You can provide two file descriptors/sockets (use 0=stdin and 1=stdout) which are used as stdin and stdout streams. This allows you to connect the sockets to something more useful than shell output, just take a look at the XtAppAddInput function or any other function with the same purpose (in Gtk+, Qt, libc, ...)

TIM image format library

• void tim_init (void);
  Initialize the library. Required.
• tim_t *tim_new (tim_mode_t mode, u_short width, u_short height, u_short ncluts);
  Create a new TIM image with the given attributes. The image is linear mapped after the returned pointer, so if you write tim_sizeof(tim) bytes you have saved the TIM image.
• void tim_free (tim_t *tim);
  Frees the TIM image.
• tim_chunk_t *tim_clut_addr (tim_t *tim);
  Get the address of the CLUT in the TIM image
• tim_chunk_t *tim_pixel_addr (tim_t *tim);
  Get the address of the first pixel in the TIM image
• int tim_sizeof (tim_t *tim);
  Get the size in bytes of an TIM image
• int tim_width (tim_t *tim,int ofclut);
  Get the width in pixels of a TIM image
• int tim_height (tim_t *tim,int ofclut);
  Get the height in pixels of a TIM image
• tim_pixel_t *tim_pixel (tim_t *tim, int x, int y);
  Get the address (16-bit pointer) for an X,Y pixel in an TIM image
• tim_pixel_t *tim_clut (tim_t *tim, int x, int y);
  Get the address (16-bit pointer) for an X,Y CLUT entry in an TIM image
• char *tim_get_alpha (tim_t *tim);
  This extracts the transparency plane, which is width x height bytes long. You should free this pointer with a call to free().
• char *tim_get_rgb (tim_t *tim, int shift);
  This will convert a TIM image into a RGB image. You should free this pointer with a call to free() if it is no more needed.

BS image format library

• void bs_init (void);
  Initialize the library. Required.
• int bs_encode (bs_header_t *outbuf,bs_input_image_t *img,int type,int q_scale,unsigned char *myiqtab);
  Encode a raw 24-bit RGB buffer directly into a BS image
• void bs_decode_rgb24 (unsigned char *outbuf,bs_header_t *img,int width, int height,unsigned char *myiqtab);
  Decode a BS image into a raw 24-bit RGB buffer
• void bs_decode_rgb15 (unsigned short *outbuf,bs_header_t *img,int width, int height,unsigned char *myiqtab);
  Decode a BS image into a raw 15-bit RGB buffer (*untested*)
