History For Scale2x

Scale2x v2.2 2005/03

• Fixed a typo in the algorithm documentation of scale3x. Specifically the definition of the E3 point in the algorithm.txt file was wrong.

Scale2x v2.1 2004/12

• Added the `scale2x3' and `scale2x4' effects.
• Fixed the computation of the border pixels for scale3x.
• Fixed the scalebit.c implementation to be C++ compatible [Max Horn]

Scale2x v2.0 2004/02

• Added a new revision of the `scale3x' effect. It now looks good as `scale2x'.
• Added a new optimized C version of the `scale2x' effect.
• Added a detailed algorithm specification in the `algorithm.txt' file.
• Minor fixes at the scalebit.c file.

Scale2x v1.6 2003/07

• Added an example of the fast implementation of the effects applied to a generic bitmap. There is also an example for the not obvious Scale4x effect.
• Revised the command line tools. Now they support all the formats of .PNG images. Also images with 16 bits per channel.
• Fixed a linking problem with some libpng installations.

Scale2x v1.5 2003/05

• Added the scale3x and scale4x command line tools.

Scale2x v1.4 2003/01

• Added in the contrib dir a VisualC MMX assembler implementation by VisualBoy from the VisualBoyAdvance emulator.

Scale2x v1.3 2002/12

• Added the contrib dir with some example implementations. Java by Randy Power and C SDL by Pete Shinners.

Scale2x v1.2 2002/11

• The new Scale2x site is now http://scale2x.sourceforge.net
• The MMX implementation now correctly computes the pixel on the left and right border.
• Renamed the -t option in -w.

Scale2x v1.1 2002/11
