I have a bunch of framed A3 picture frames that I would like to use by taking screen captures of dos games using MSI Afterburner's on screen display while in Dosbox to capture shots but games default to 4:3 ratio no matter what custom resolution I put in the config file (full screen and windowed and aspect=false), short explanation I need to add 46 pixels to 1920 pixels to stretch the image capture to fill my A3 picture frame when printed at the shop, if you are interested below is the long explanation.
A3 frame holds pictures the size of 42cm x 29.7cm
using math there would be borders on each side of the frame equal to 1.2cm on each side at 4:3, so to stretch the capture to the full A3:
29.7 / 3 = 9.9
9.9 x 4 = 39.6
42 - 39.6 = 2.4
2.4 / 2 = 1.2, 1.2cm on each side
2.4 % of 1920 = 46.08
1920 + 46 = 1966, so I will need a resolution of 1966x1440 to fill the A3, I have a 16:10 monitor at 2560x1600 and the 4:3 of 2560x1600 is 2133x1600 but there is a slight quality difference in the captures I have done between 1920 and 2133, 1920x1440 was best quality. So after this long explanation how can I make Dosbox do a slightly stretched 4:3 image? Or was all of this a big waste of time because the printing shops can do the stretching for me 😐
