c# - Resize and Fit Image in WPF -

i have following:

using (bmp == new bitmap(50, 50)) {     using (g == graphics.fromimage(bmp)) {         g.interpolationmode = drawing2d.interpolationmode.highqualitybicubic;         g.drawimage(img, 0, 0, 50, 50);     } } 

the user provides app image app has resize , fit entire image.

the problem above code stretches image, not fit (as 4:3 movie fits in widescreen tv leaving blackbars).

does have solution this? also, prefer not use gdi.

you need take size of input image account. here code snippet should right direction:

int x1 = 0, y1 = 0, x2 = 50, y2 = 50; if (img. width <= img.height)  {    // compute x1, y1 fit img horizontally bmp } else {    // compute y1, y2 fit img vertically bmp }  g.drawimage(img, x1,y1, x2,y2); 

also notice asking resizing image in wpf using system.drawing uses gdi+ under hood.
