# Declare each of the functions in the public BLT interface. Note that

### Reading and writing image data from channels and/or strings.
declare 0 generic {

CONST char *fileName, int permissions)
}
declare 1 generic {
int tkimg_ReadInit (Tcl_Obj *data, int c, tkimg_MFile *handle)
}
declare 2 generic {
void tkimg_WriteInit (Tcl_DString *buffer, tkimg_MFile *handle)

### Specialized put block handling transparency
declare 10 generic {
int tkimg_PhotoPutBlock (Tk_PhotoHandle handle,
Tk_PhotoImageBlock *blockPtr, int x, int y, int width, int height)
}

### Utilities to help handling the differences in 8.3.2 and 8.3 image types.
declare 20 generic {
void tkimg_FixChanMatchProc (Tcl_Interp **interp, Tcl_Channel *chan,
CONST char **file, Tcl_Obj **format, int **width, int **height)

Tcl_DString **dataPtr, Tcl_Obj **format, Tk_PhotoImageBlock **blockPtr)
}

### Like the core functions, except that they accept objPtr == NULL.
### The byte array function also handles both UTF and non-UTF cores.
declare 30 generic {
char* tkimg_GetStringFromObj (Tcl_Obj *objPtr, int *lengthPtr)
}
declare 31 generic {
char* tkimg_GetByteArrayFromObj (Tcl_Obj *objPtr, int *lengthPtr)
}
declare 32 generic {
int tkimg_ListObjGetElements (Tcl_Interp *interp, Tcl_Obj *objPtr, int *argc, Tcl_Obj ***argv)
}
