Scale a .P...le effects(1) General Commands Manual Scale a .P...le effects(1) NAME scalerx - Scale a .PNG image using the reference implementation of the Scale effects SYNOPSIS scalerx [-k N] [-w] [-r N] input.png output.png DESCRIPTION Scale2x, Scale3x and Scale4x are real-time graphics effects able to in- crease the size of small bitmaps guessing the missing pixels without blur- ring the images. They were originally developed for the AdvanceMAME project in the year 2001 to improve the quality of old games running at low video resolutions. The specification of the algorithm and more details are at: http://scale2x.sourceforge.net These command line tools read a .PNG file and write another image with the effects applied. The reference implementation of the Scale effects is used. OPTIONS -k N, --scale N Select the scale factor. Available values are 2, 2x3, 2x4, 3, and 4. -w, --wrap Compute the image border for a wraparound effect. -r N Select a specific revision of the effect. The default is scaleX us- ing algorithm 'x' or '1'. To select the new scaleK use algorithm 'k' or '2'. To scale an image without any effect use the value '0'. Other nunbers are alternative versions. Refers at the source imple- mentation for more details. COPYRIGHT This file is Copyright (C) 2003, 2004 Andrea Mazzoleni Scale a .P...le effects(1)
