Hello: The command line to rotate by 90 (and similarly for 180 and 270) degrees is described in the manual as: vips im_rot90 in.png out.png However, nip2 has the additional feature to rotate by an arbitrary amount (say 7.5 degrees) But there seems to be no such command as the one below: vips im_rotate in.png out.png 7.5 <--- command not recognized Further, nip2 (toolkits->image->transform->rotate->free) gives the option of bilinear, Bicubic,upside,upsharp and upsmooth algorithms). ------------- Question: Is this functionality available in command line version? Thanks Doug
