It's still work with 1.1
Sorry for my English again.

Need change "clean" to "clear" (control.lua:259 and data.lua:23)
And change strings 122..126 (add "tostring") in control.lua to pmain['xres_text' ].text = tostring(camera_settings.w)
pmain['yres_text' ].text = tostring(camera_settings.h)
pmain ...

I chose ceil, because it’s better to take one extra pixel and guaranteed to capture the selected rectangle than not to get one pixel. However, there is no difference, this is just one pixel.

Hey, can you fix lines 141..145 (control.lua) from
args.xpos = tonumber (pmain['xpos_text' ].text)
args.ypos = tonumber (pmain['ypos_text' ].text)
args.xres = tointeger(pmain['xres_text' ].text)
args.yres = tointeger(pmain['yres_text' ].text)
args.zoom = tonumber (pmain['scale_text' ].text ...
