java - resizing an image without compromising the aspect ratio -


i use following codes resize image problem don't maintain original aspect ratio, there way can resize image without compromising aspect ratio.

bufferedimage img1 = new bufferedimage(800, 600,                     bufferedimage.type_int_rgb);             img1.creategraphics()                     .drawimage(                             imageio.read(                                     new file("/home/rvkydmpo/webapps/root/images/profilepicture/"                                             + filename)).getscaledinstance(800,                                     600, image.scale_smooth), 0, 0, null);             imageio.write(img1, "jpg", new file("/home/rvkydmpo/webapps/root/images/profilepicture/" +filename));

you might want read the docs of getscaledinstance():

image java.awt.image.getscaledinstance(int width, int height, int hints)

creates scaled version of image. new image object returned render image @ specified width , height default. new image object may loaded asynchronously if original source image has been loaded completely.

if either width or height negative number value substituted maintain aspect ratio of original image dimensions. if both width , height negative, original image dimensions used.

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
