OK now I am getting something into the XPCOM, the problem is I don;t know what.
in JavaScaript var nary = new Array(); nary[0] = document.images[0]; var ocnt = []; comp.func(nary,1, oary, ocnt); when I break in the func I see a pointer to something. but I don't any other pointers in the memory "x/20 img" I don;t even know what question I should ask now. I want to get access to the image data in a .gif and .png in a <img > html document Shaun Christof Meerwald wrote: > On Sat, 06 Jul 2002 23:12:20 -0700, Shaun Savage wrote: > >>How do you get binary data from XPCOM to JavaScript. > > > You have to use an octet array: > > void func([array, size_is(length)] in octet data, in unsigned long length, > [array, size_is(out_len)] out octet out_data, > out unsigned long out_len); > > > >>I am tring to do it as a string (in idl). > > > A XPCOM string is always zero-terminated and ASCII only (7 bits). > > > bye, Christof >
