I have a little doubt, I was analyzing the files of a software in DirectX 8 and I saw that it does something that I can not understand how, it takes a base image, let's call frame.dds and resizes it from an initial resolution of say 128x116 to something of the type 401x73 , all using only DirectX I believe and without losing ANY quality in the final image, follow examples of the images in question:
Initial:
Final:
How is this possible? Could someone explain me? I tried doing the same using sprites and in Sprite-> Draw I would modify the scalling, until it worked but I lost a lot of quality in the final image, the corners were blurred and etc ...
