Chart Tool calculates chip vertices from the chart outline. Give option to easily transfer those values through the Results Table

Currently all fields, but alignmentTransform, are assumed immutable. Make alignmentTransform immutable and add mutability guards for other fields, e.g., copy mutable objects like arrays.

ij-plugins toolkit contain color conversion plugins but does not allow to select options like reference white, XYZ scale, etc. Replace ij-plugins toolkit conversion plugins with improved versions.

Currently the reference white for ColorChart is fixed as D65. It should be possible to use other standard illuminants, like D50.

Cross compile for Scala 2.12 and 2.13

When a plugin start next time is should bring previous values of the options

Mark created/displayed images as composite so they are displayed as color

Implement DeltaE 2000 and add tests comparing to Lindbloom calculator: http://www.brucelindbloom.com/index.html?ColorDifferenceCalc.html

The default MAGENTA color is not sometimes well visible, allow user to change

Starting page for ScalaDoc is empty. Add basic description with link to project page.

Use it in addition to Travis CI for some time to see how it performs

Show error for each color band

Do all computations automatically. Move advanced options to a separate dialog.

Allow interactive placement of color chart ROI rather than importing from the image after ROI adjustment

See: ij-plugins/ijp-toolkit#17

Allow user creation of a custom color chart where user provides:

• number of columns
• number of rows
• reference white
• CIE L*a*b* reference color values for each chip for given the reference while

This may be useful if chip reference values are not usable, for instance, a reference sRGB value is negative and otherwise using sRGB as a reference color space is desirable

Add definition for ColorGauge chart from Image Science Associates and make it available from the Calibrator plugin.

• "core" library implements main computational functionality, no UI
• "ui" adds UI components and ImageJ plugins

Some of the errors (on Calibrate, Suggest Options) are not shown, only printed to console.

It will be very useful to see which point belongs to which chip. It could be done by adding a mouse-over effect: when cursor moves over a point display it's chip name

Default FIJI distribution contains Scala 2.12. Try supporting Scala 2.12 to avoid conflicts with FIJI.

ImageJ's GenericDialog does not behave well when opened from a JavaFX dialog. Add simple emulation that will use JavaFX for UI.

Simplify package name, drop historic location, match new convention in other other IJ Plugins projects

The set a null icon on OSX.

Show how to use Color Calibrator from a script, for instance for batch calibration

When image slices have null labels use slice number as label

Help deal with situations when color chart is on one image but calibration needs to applied to different image captured under the same conditions as the chart image.

I downloaded the latest ImageJ and ijp-color. I can run the Color chart tool but if I try the Color calibrator I get an error message 'Unknown Error' with this output:

During calibration, when "Select extra info" is selected, a large number of windows will be open cluttering the screen. Let user select which information to show.

JavaFX dependency is OS dependent, when you make it a transitive dependency, chance is that somebody using it on different OS than that it was build for will run into issues.

In SBT mark JavaFX dependencies as "provided".

As discussed in this issue: #51

I am interested in computing a 3x3 color correction matrix for a camera sensor based on captured images of a Macbeth style color checker chart.

4x3 color correction matrices are also of interest but effectively covered by the current linear cross plane option.

Constructor in GridColorChart have different order of arguments, make them similar

Images that represent colors as separate gray level slices are not handled correctly, resulting in exception.

Color corrector currently assumes that a variant of a polynomial fit us used for approximation. Allow adding other approximation approaches by making Corrector abstract

Currently ReferenceColorSpace assumes D65 illuminant in toLab functions. This will result in incorrect conversion if reference colors used different illuminant and converting.

Scala Enumeration can lead to awkward syntax with *.Value and other issues, see https://pedrorijo.com/blog/scala-enums/

Help to visualize how target values compare to actual chip color values by displaying target patches on top of each chip. For original image that would be reference value for corrected color image that would be sRGB value.
