imager 0.40.2 Minor release

* added crop.bbox for cropping image to the bounding box of a pixset
* updated CImg: fixes issues with Intel C compiler and libtiff giving pop-up warnings on Windows 
* threshold now has an "adjust" argument, to adjust the auto-thresholding

imager 0.40.1 Minor release

* Updated CImg, imager should now compile on Solaris
* Fixed memory access bug in px.flood

imager 0.40 Major release

• added pixset class to represent sets of pixels in an image (implemented as binary images). A test on an image (e.g., im > 0) results in a pixset object. Pixsets come with many convenience functions for plotting, manipulation, morphology, etc. They are described in the "pixsets" vignette.
• improved reductions (parmax, parmin, etc.). Most are now implemented in C++ and some run in parallel using OpenMP. A median combine operation (parmedian) has been added.
• added load.video, save.video, make.video functions. Loading and saving videos used to be a bit fragile and platform-dependent, it should now be easier and more robust (also slower, sorry). It's now possible to load individual frames from a video. You still need ffmpeg.
• to load images from URLs imager now uses the downloader package, which is more robust than the previous solution
• it's now possible to import images from the raster package and from the magick package.
• unified RGB representations so that every function expects RGB values to be in the [0-1] range. There used to be a conflict in expectations here, with R expecting [0-1] and CImg [0-255]. This might break existing code (albeit in minor ways).
• new function implot, lets you draw on an image using R's base graphics.
• improved interactive functions for grabbing image regions (grabRect, grabLine, etc.)
• improved grayscale conversion
• improved plotting. The default is now to have a constant aspect ratio that matches the aspect ratio of the image.
• save.image now accepts a quality argument when saving JPEGs.
• native support for TIFF, now supports non-integer values in TIFF files
• rm.alpha removes alpha channel, flatten.alpha flattens it
• imfill now accepts colour names, e.g. imfill(10,10,val='red')
• improved documentation and examples
• added functions for conversion to/from CIELAB

imager 0.31 Minor release

• fixed inline C++ plugin, this time for OS X systems
• added interpolation option to plot.cimg (to prevent systematic antialiasing when plotting small images)

imager 0.30 Major release.

• new S3 class imlist improves support for image lists
• enabled OpenMP. Many CImg primitives now run in parallel.
• experimental support for CImg's DSL via imeval, patch_summary.
• improved as.raster,plot. Now support palettes via colourscale argument.
• new interactive functions for selecting image regions (grabRect,grabPoint,grabLine)
• new patchstat function for fast extraction of patch statistics
• new patchmatch function
• cleaned up the API, improved the documentation
• fixed bug in inline C++ plugin, should now work on Windows.
• improved configure script. FFTW3 is now optional (should be less confusing to OSX users)

imager 0.20. Major release

• added a tutorial (vignette), which includes a worked-out example of multi-scale blob detection
• new functions:
  • iminfo gives you information on an image file (uses ImageMagick)
  • load.example loads test images
  • crop.borders (self-explanatory)
• long computations can now be interrupted thanks to update in CImg
• the array subset operator is now more intelligent: you do not have to specify flat dimensions, i.e. imfill(10,10)[3,1] does what you'd expect (i.e., the same as imfill(10,10)[3,1,1,1])
• improvements and bugs fixed in print.cimg, as.cimg, imresize, frame, plot.cimg, subim, as.raster, renorm
• improved documentation and examples

imager 0.16. Bugfix + minor features

• as.data.frame.cimg now has optional "wide" formats
• load.image now uses readbitmap by default (should work better on Windows)
• Made the test for ImageMagick more stringent, which fixes a bug in load.image on certain machines
• Added new reductions which.parmax, which.parmin

imager 0.15: Substantial update

• User-visible changes:
  • the threshold function now supports auto-thresholding (based on k-means)
  • new accessor functions: imrow, imcol
  • new replacement functions: channel(im,1) <-, R(im) <- , etc.
  • new reduction function: enorm (Euclidean norm of a list of images)
  • improved as.cimg.function, pixel.grid
  • subim is now called imsub for greater consistency (imsub still available as alias)
  • improved documentation
• Other:
  • Reorganised R code into separate files for clarity

0.14 Minor update

• Build system now uses configure
• Fixed paths in Makevars
• Hopeful bugfix in load.image for Windows 7 users

0.13 Initial release on CRAN
