directx - Generating a 16-bits per channel PNG file procedurally -


is there way generate 16-bits per channel(rgba) png file using d3dx11savetexturetofile? or version of directx, image library(c++), image format

i tried use sample code here: http://msdn.microsoft.com/en-us/library/windows/desktop/bb205131(v=vs.85).aspx

and modified function names d3d11 version.

the program works when set desc.format dxgi_format_r8g8b8a8_unorm .

but d3dx11savetexturetofile returns e_fail when changed desc.format dxgi_format_r16g16b16a16_unorm .

i've tried use devil (developer's image library) doesn't support 16-bits per channel png file.

the format can save texture-formats d3dx11_iff_dds. seems d3dx11savetexturetofile can't save 16bit pngs. 1 possibility extract imagedata of texture , save manually 1 of possibilities (e.g. opencv or libpng) discussed here: writing 16 bit uncompressed image using opencv.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
