PngEncoder Change Log
|
Version 2.0.1 to 2.0.2
|
-
Fixed a bug where the images were not encoded properly in COLOR_TRUECOLOR, COLOR_TRUECOLOR_ALPHA and
COLOR_GRAYSCALE_ALPHA when the source image were read using ImageIO.read()
-
Now when encoding to an indexed color image the proper algorithm is chosen depending on the
color count of the original image:
- setIndexedColorMode(PngEncoder.INDEXED_COLORS_ORIGINAL) - use pixels from original image,
should be used when there is less then 256 colors in the original image
- setIndexedColorMode(PngEncoder.INDEXED_COLORS_CONVERT) - convert pixels to make sure all
pixels are written to the target image
- setIndexedColorMode(PngEncoder.INDEXED_COLORS_AUTO) - let the PngEncoder find the best
mode automatically. May take longer time to encode

|
Version 2.0 to 2.0.1
|
- Fixed a bug where some colors where written as white when converting from TRUECOLOR to INDEXED
|
|
Version 1.1 to 2.0
|
- Added possibility to encode images with alpha transparency:
PngEncoder encoder = new PngEncoder(PngEncoder.COLOR_TRUECOLOR_ALPHA);
PngEncoder encoder = new PngEncoder(PngEncoder.COLOR_GRAYSCALE_ALPHA);
PngEncoder encoder = new PngEncoder(PngEncoder.COLOR_INDEXED_ALPHA);
- Increased the speed of the encoding even more
|
|
Version 1.0.1 to 1.1
|
- Added possibility for indexed encoding.
PngEncoder encoder = new PngEncoder(PngEncoder.COLOR_INDEXED);
- Added possibility for grayscale encoding.
PngEncoder encoder = new PngEncoder(PngEncoder.COLOR_GRAYSCALE);
|
|
Version 1.0 to 1.0.1
|
- Removed the obfuscation from the public fields COLOR_INDEXED
COLOR_TRUECOLOR, DEFAULT_COMPRESSION, BEST_SPEED, and BEST_COMPRESSION.
