Change Log

1.0.4.1

Bug Fixes

  • Fixed an issue where GimpPaletteSerializer.Deserialize could get itself stuck in an infinite loop if a GPL file was formatted a certain way
  • GimpPaletteSerializer.Serialize now uses ASCII encoding instead of UTF-8, fixing a problem where palette files couldn't be opened in Inkscape.

1.0.4.0

Changes and new features

  • Added new AdobePhotoShopColorSwatchSerializer serializer for reading and writing Adobe PhotoShop colour swatches (both version 1 and version 2)
  • You can now set the Columns property of a ColorGrid control to 0, which will then internally calculate columns based on the size of the control, the cell size, and the spacing. A new read-only ActualColumns property has been added which will allow you to get the real number of columns if required. The AutoSize behaviour has been changed so that only the vertical height of the control is adjusted when Columns is zero
  • Save Palette button in the ColorPickerDialog now obtains the serializer to use based on the selected filter index, allowing correct saving if multiple serializers use the same extension.
  • Added CanReadFrom method to IPaletteSerializer.
  • PaletteSerializer.GetSerializer now makes use of the above new method to access the relevant serializer rather than just matching extensions. This means if you have two serializers that support different .pal formatted files, these can now be loaded successfully, instead of one loading and one failing.
  • Added new RawPaletteSerializer which reads and writes palettes that are simply RGB triplets in byte form
  • Added new ShowAlphaChannel property to ColorEditor and ColorPickerDialog. This property allows the alpha channel editing controls to be hidden, for when working with 8-bit colours.
  • The rendering of the selected cell in a ColorGrid control who's SelectedCellStyle is Zoomed now uses Padding.Left and Padding.Top to determine the size of the zoom box, avoiding massive boxes the larger the CellSize gets.
  • Added a new standard 256 colour palette. You can use this in the ColorGrid by setting the Palette property to ColorPalette.Standard256 or obtain the array of colours by calling ColorPalettes.StandardPalette
  • ColorGrid and RgbaColorSlider controls now only create transparency brushes when required. A new virtual method SupportsTransparentBackColor allows inheritors to create their own brushes if required.
  • Added EditingColor event to ColorGrid, allowing the edit colour action to be cancelled, or replaced with a custom editor
  • Added CurrentCell property and GetCellOffset methods to the ColorGrid.
  • ColorCollection now implements IEquatable
  • Added more tests
  • Added new Navigate method to ColorGrid for easier moving within the cells of the grid

Bug Fixes

  • The ColorGrid control now tries to be smarter with painting, and only paints cells that intersect with the clip rectangle. In addition, where possible only individual cells are invalidated rather than the entire control.
  • Corrected invalid error messages from the Save Palette button in the ColorPickerDialog.
  • Load Palette and Save Palette buttons in the ColorPickerDialog now check the CanRead and CanWrite properties of the serializer.
  • Double clicking with any button other than the left in ColorGrid control no longer attempts to initiate colour editing
  • Setting the Color property of the ColorGrid control to Color.Empty no longer treats the value as a valid colour
  • The ColorGrid control no longer defines custom colour regions when the ShowCustomColors property was false. This manifested in hover and selection effects working if you moved your mouse over the bottom of a resized grid.
  • Clicking "white space" areas of a ColorWheel control will no longer incorrectly set the colour to the closest matching point on the wheel itself. However, starting to select a colour within the wheel and then moving outside the bounds will continue to select the closest match as usual.
  • Fixed a crash that occurred when creating controls that inherited from ColorGrid or RgbaColorSlider
  • When the AutoAddColors and ShowCustomColors properties are false, unmatched colours will no longer be silently added to the ColorGrid custom palette unexpectedly. This also resolves various crashes after the colour regions fix above was applied.
  • The ColorWheel control now makes use of ButtonRenderer.DrawParentBackground to draw itself, to avoid ugly blocks of solid colours when hosted in containers such as the TabControl
  • The ColorEditorManager control's ColorChanged event has now been marked as the default event, so when you double click the component in the designer, a code window now correctly opens.
  • If the underlying entry in a ColorCollection bound to a ColorGrid control was modified, and this particular entry was the selected colour, the ColorGrid would not keep its Color property in sync and would clear the selected index.
  • Attempting to set the Columns property to less than zero now throws an ArgumentOutOfRange exception rather than setting it, then crashing later on
  • Double clicking a colour in the grid of the ColorPickerDialog no longer opens another copy of the ColorPickerDialog
  • Fixed problems in the ColorGrid with keyboard navigation and initial focus if no valid colour index was set.
  • The ColorCollection.Find method now correctly works when adding named colours (e.g. Color.CornflowerBlue) to the collection, but searching by ARGB value (e.g. Color.FromArgb(100, 149, 237))
  • Fixed an issue where if the internal dictionary lookup in ColorCollection class had been created and the collection was then updated, in some cases the lookup wasn't correctly modified.

1.0.3.0

Changes and new features

  • Added Find method to ColorCollection
  • Replaced ColorComparer.Brightness with version derived from here
  • Added new InterleavedBitmapPaletteSerializer class, that allows palettes to be loaded from ILBM (IFF Interleaved Bitmap) format files (LBM images or BBM palettes). Note: Writing is not yet supported.
  • Added CanRead and CanWrite properties to IPaletteSerializer to indicate input/output support.
  • The PaletteSerializer.DefaultOpenFilter and PaletteSerializer.DefaultSaveFilter make use of the above properties when building filters
  • Added the ability for multiple extensions to be supplied.
  • The colours displayed in the drop down list component of the ColorEditor now only load when the drop down is opened, or the Up, Down, Page Up or Page Down keys are pressed
  • Reworked the ColorEditor control to work nicer with RGB colours. Previously, the Color property was a wrapper around the HslColor property, meaning if you set it to a named colour such as Color.Red, the name was lost, and the hex/name editor didn't show the name. Now it keeps track of both colours, so if you set it to a named value, you can see (and get) the named value back.
  • Reworked the ColorEditorManager component to also store separate copies of the RGB/HSL colours instead of loosing named colour information
  • Experimented with making the hex/named colour field in the ColorEditor control slightly wider than the other controls. Looks a touch odd now that all fields aren't a uniform width, but does make it much easier to read that the selected colour is LightGoldenRodYellow!

Bug Fixes

  • Setting the SelectionSize property of the ColorWheel didn't resize the wheel as it was supposed to
  • When the orientation of a ColorSlider (or derived control) was Vertical, the colour bar was drawn in the reverse order of the scale.
  • Changing the Value of the LightnessColorSlider control now correctly updates the Color property of that control, in turn making the ColorEditorManager change the luminosity of linked controls. Also setting the Color of the LightnessColorSlider now correctly updates the Value. This now means you can bind a ColorWheel to a LightnessColorSlider for full control over the brightness of a colour, which is not possible to do with the wheel alone.

1.0.2.3

Changes and new features

  • Added static LoadPalette and instance Load methods to ColorCollection
  • Added Save method to ColorCollection
  • Added new constructor to ColorCollection that accepts a System.Drawing.Imaging.ColorPalette class.
  • Added new AutoFit property to the ColorGrid. When set, the CellSize property is automatically calculated based on the size of the control, and its contents. You can't combine AutoFit with AutoSize.
  • ColorCollection is now clone-able

Bug Fixes

  • Removed unnecessary UpdateStyles calls.
  • Fixed a problem if a window was opened by pressing Enter, and a ColorGrid was the first focusable control on the new window, the pop-up colour editing dialog would be activated, regardless of the ColorGrid's editing settings

1.0.2.2

Changes and new features

  • Added Name and DefaultExtension properties to IPaletteSerializer
  • Added new static properties DefaultOpenFilter and DefaultSaveFilter, and static method GetSerializer to PaletteSerializer. These allow the use of reflection for easily providing palette load and save functionality automatically based on loaded assemblies.
  • Added the SupportsTransparentBackColor control style to ColorGrid
  • Added system colours to the ColorEditor named colour drop down
  • Added a new DoubleSoft cell border style to the ColorGrid

Bug fixes

  • Setting the Spacing or CellSize properties of the ColorGrid control didn't recalculate the layout
  • ColorEditor now uses TextRenderer.DrawText instead of Graphics.DrawString so all text is rendered consistently.

1.0.2.1

Changes and new features

  • Added new constructor to the ColorCollection class that accepts an IEnumerable<int>
  • ColorCollection now implements IClonable
  • Added dotted outline to design time ColorGrid control

Bug fixes

  • Fixed invalid default value for the EditMode property of a ColorGrid
  • Fixed AutoSize property of ColorGrid control not being persisted

1.0.2.0

Note: Several of the updates in this version are breaking changes due to renaming of classes and enum values. Some more changes to your code will be required to use the new Color Picker API.

Changes and new features

  • IPaletteReader replaced with IPaletteSerializer
  • JascPaletteReader replaced with JascPaletteSerializer
  • GimpPaletteReader replaced with GimpPaletteSerializer
  • PaintNetPaletteReader replaced with PaintNetPaletteSerializer
  • The values of the ColorEditingMode enum have been renamed to make more sense.
  • The ColorEditor now supports selecting of named colours as the hex editor is now a drop down list. As well as being able to select named colours from the list, you can now also type names directly into the hex editor and they will be processed accordingly.
  • The ColorPickerDialog now can load and save palette files
  • Palette support has been reworked to allow the saving of palettes as well as loading. Unfortunately due to the initial names of these classes this is a breaking change.
  • Added a bit more documentation

Bug fixes

  • Corrected some grammatical errors in existing documentation and headers

1.0.1.0

Changes and new features

  • Added GimpPaletteReader for reading palette files created by Gimp
  • Added ReadPalette(fileName) overload to IPaletteReader
  • Renamed Jasc10PaletteReader to JascPaletteReader
  • Reworked Jasc palette import to match how Gimp is doing it
  • Added a testing project. Currently this just tests the different palette readers are importing data correctly.

1.0.0.0

  • Initial Release
