QrGenerator
has a new methodnoAlpha()
which strips off the alpha channel from all selected colors.
- It is now possible to render the three markers of the generated QR codes
in different styles. The markers of the QR code can now be drawn as
- rectangles
- rectangles with rounded corners
- circles
- 'raindrops' appearing to fall inward
- 'raindrops' appearing to fall outward
- rectangles with one rounded edge at the outer corner
- rectangles with one rounded edge at the inner corner
- rectangles with rounded edge except one sharp edge at the outer corner
- rectangles with rounded edge except one sharp edge at the inner corner
- When giving a color as parameter you can now choose between ARGB, RGBA, RGB, HSLA and HSL
- It is now possible to select extra colors for the three QR code's markers. The inner and the outer parts of the markers can be rendered with different colors (if requested).
- Added new style options for generated QR codes. The "pixels" of the QR code
can now also be
- rectangles with rounded corners or
- they can be merged in a way
- to form rows or columns
- to form snake-like structures
- to form structures like water (with adhesion)
- the colors to be used can no longer be given as raw integer values.
Instead you have to feed the
withColors(...)
methods whith instances ofArgbValue
,RgbaValue
,RgbValue
,HslaValue
orHslValue
- Classes ArgbValue, RgbValue and ImgParameter had no real 'equals()' method. Fixed this by introducing lombok
- Added new configuration option for generated QR codes: the "pixels" of the QR code can now also be dots
- Added another option to draw "smaller (rectangular) pixels" so that a thin grid appears in between
- Changed name of the enum to selsect generated file format from ImageType to ImageFileType
- Started writing unit tests
- Added README.md
- Added javadoc
- Implemented wrapper around ZXing for generating QR codes
- wrapper can be reused (for multiple payloads)
- generated QR code can be configured wth respect to
- size of generate image
- file type of produced image (BMP, PNG, JPG, GIF)
- colors of "on" and "off" pixels
- error correction level
- character encoding of encoded payload
- margin around the QR code (to help scanners)
- generator can place a logo centered over the QR code
