How do I create a transparent gif in Go? -


when encode gif in go, background black. how make background transparent?

here code in http handler. (w responsewriter)

m := image.newrgba(image.rect(0, 0, pixelwidth, pixelheight)) gif.encode(w, m, &gif.options{numcolors: 16})

i read source of image/gif , found there has transparent color on palette.

var palette color.palette = color.palette{     image.transparent,     image.black,     image.white,     color.rgba{0, 255, 0, 255},     color.rgba{0, 100, 0, 255}, }  m := image.newpaletted(image.rect(0, 0, pixelwidth, pixelheight), palette) gif.encode(w, m, &gif.options{})

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
