Pre-release version 0.0.6

Release Notes for Scala Media Computation Library 0.0.6

In addition to miscellaneous small refactorings, additions, and bug fixes that have been introduced, the most essential changes are listed below.

Color-Related Functionality

• Adds toString method to PresetColor.
• Changes the equality of Color instances as follows:
  • By default (by using .equals() and ==) equality is determined by the four color values (RGBA) only. Also, hash codes are calculated on the basis of those four values only.
  • Method equalsIncludingName() considers also canonical names of the colors.
  • In addition to the above, method equalsIncludingNameAndPresetness() also differentiates colors based on whether or not both of the colors are presets.
• Adds an is() method that directly calls the equals() method.
• Implements darker() and lighter() methods for colors as simplified versions for shading and tinting. These methods use constant factors instead of accepting them as their parameters.
• Fixes a color tinting calculation bug.
• Implements some methods for mixing colors based on given proportion of other given color.

Bitmap-Related Functionality

• Implements crop() method for the new Bitmap class and removes the related code from the old architecture.
• Refactors bitmap iteration and offers several kinds of methods for performing it, including the following ones in the Bitmap class:
  • mergePixelsWith() for merging two bitmaps using a function that merges colors of two pixels.
  • setColorsByLocation() accepts a function that determines color for a pixel by its coordinates.
  • transformColorToColor() accepts a function that determines a new colors for a pixel based on its current color.
  • transformLocationColorToColor() accepts a function that determines a new colors for a pixel based on its current color and location.
  • iteratePixels() accepts a function that receives a mutable Pixel instance and modifies it to set a new color for the corresponding pixel.
  • colorAt() returns the color of a pixel in the specified coordinates in the bitmap directly from the related Java/AWT BufferedImage without using a PixelSnapshot.
• Moves some bitmap filters, including palette-based color channel, grayscale, and posterization filters, from the old architecture to be usable with the new Bitmap class.
• Refactors matrix iterating functionality out of pixel snapshot iterators into generalized enumerator and iterator classes that are located in their own packages under the infrastructure package.
• Moves pixel snapshot iterator classes into smcl.pictures.iterators package.

Other User-Visible Functionality

• Adds methods to convert Pos instances into
  • new Pos instances using given conversion functions
  • tuples of (floored) Ints and Doubles.
• Adds methods to wrap Pos instances into tuples with other values.
• Renames position type constants to PosTypeUpperLeftCorner and PosTypeCenter.
• Renames viewer update style constants to VUSPreventViewerUpdates and VUSUpdateViewerPerDefaults. These are are not currently being used in the new architecture's API.
• Fixes a percentage validation bug in CommonValidators.

Indpendent JVM/AWT-Specific Low-Level Functionality

• Changes more of the Bitmap interface to use Doubles instead of Ints.

Build Process

• Changes SBT version to 1.1.1.
• Sets versions of sbt-env-vars and sbt-library-info to 0.1.2 and 0.2.2, respectively.
• Starts to prepare for transition to Scala.js 1.0.x.
• Removes withSources() and withJavadoc() calls from build.sbt, as they are not recommended to be used (and IntelliJ IDEA may not like them).
• Removes unnecessary constants from build.sbt.
• Updates .gitattributes.
• Adds a script as well as related shortcut icons and .desktop file templates for launching standard SMCL development terminals for SBT and Git in Bash/Gnome environment.

Pre-release version 0.0.5

Release Notes for Scala Media Computation Library 0.0.5

Pre-release version 0.0.4

Release Notes for Scala Media Computation Library 0.0.4

In addition to miscellaneous refactorings, small additions, and bug fixes that have bee introduced, the most essential changes are listed below.

User-Visible Functionality

• Viewports can be used to set pictures' sizes.
• Picture elements can be combined into new pictures in various ways.
• Picture elements can be replicated and alternated with others to create new pictures.
• Polygons and basic arcs are implemented.
• Polygons and arcs are used to provide triangles, rectangles, regular pentagons, regular star pentagons, circles, ellipses, and crosshairs.
• Object's positions will be their center points.
• Shape-related coordinates in the DrawingSurfaceAdapter are changed to be Doubles.
• Bitmaps can be loaded from files.
• Bitmaps can be iterated as pixels as well as colors by pixels.
• Rotation is implemented for shapes (scaling and shearing are missing, as well as rotation for bitmaps).
• An "enumeration" SideIndependentAlignment has been added.
• Double-based settings are added and some Int-based settings are converted into Double-based ones.
• A setting for regular star pentagon's cusp radius is added.
• A bunch of helper methods is added for instance to Dims, Bounds, Pos, Movable, and Rotatable.
• Object equality has been implemented for RGB colors.
• Bmp is renamed to Bitmap, Image to Picture, and ImageElement to PictureElement.
• AspectRatio class is added.

Build Process

• The code providing build information is created by a custom-made sbt-build-info plugin that copies and filters the files from a separate template project that has been added.
• Adds custom-made sbt-env-vars plugin for reading values of environment variables.
• Adds sbt-slack-notify plugin for later implementation of automatic build notifications.
• Started to add support for sbt-github-release and sbt-release plugins.
