You can activate the workbook in Project Explorer.Ĭlick the third L*a*b* Plot button, a dialog will be opened and ask the user to choose a goal.
Workbook data for the graph will be hidden. If you want to show color temperature in CIE 1931, click Show/Hide Color Temperature button on the bottom right of the graph. A chromaticity diagram with points for PL data will be created. Choose plot type ( Scatter or Line+ Symbol) and determine whether to show spectrum labels in the graph.
Two options are available: CIE 1931 and CIE 1976.
In Graph branch, select CIE type for the diagram. For the latter, select Spectral Power Distribution of Illuminant, four options are available, A, D50, D65 and Custom, for the custom type, user should replace PL sheet's column M with his actual SPD data in the app folder's Chromaticity.ogwu file. Select Standard Observer: CIE 1931 2° or CIE 1964 10°, which defines the color matching function. The latter requires input to be between 0 and 1. In Settings branch, select Spectral Type, two types are available: Radiance and Reflectance or Transmittance (0-1). You can choose multiple PL spectra, and each PL spectrum corresponds to a point in the chromaticity diagram. Choose Phtoluminescence Spectra (PL spectra) from the worksheet or the active graph. Click the second button, and it will open the PL2CIE dialog. You can also add your own data to the graph template. Open the graph window by double clicking on the worksheet's cell. In the third sheet, two graph templates ( CIE 1931 and CIE 1976) are inserted. A toolbar with three buttons will appear.Ĭlick the first button, and it will open a workbook template. With a worksheet or a graph active, click the app icon. An icon will appear in the Apps Gallery window. Plot L*a*b* data in 2D, 3D and convert L*a*b* data to CIE 1931 xyY.ĭownload ChromaticityDiagram.opx file, and then drag-and-drop onto the Origin workspace. Calculate CIE XYZ from photoluminescence spectra and add PL data to the chromaticity diagram. Open a workbook template with CIE 1931 color space chromaticity diagram and CIE 1976 UCS (uniform chromaticity scale) diagram. Last but not least, for every color, we also profile Adobe Kuller-like function to provide harmony color palette, which is good for designer or artist. Users can also organize samples color in a color-palette organizer. Also, this app also provides real-time color sampling by live camera view, or by analyzing a photo. Based on CIE color specification, several tools are developed to provide color space conversion among XYZ, xyz, LAB, HSI, HSV, color temperature, etc. #Cie color calculator software android
We port our color conversion algorithm (in native C++) to Android platform as an app, Color Calculator. There are very good online material for these topics, for example, Bruce Lindbloom has a very good Bruce Lindbloom for all these information. Besides that, digital photo developing is quite popular now, color monitor/printer profiling is also a topic we need to know so we can guarantee the color perception value are matched among all involved parties. Also, some algorithms we are using may work best in some color space than others. With deep understanding of color science, we can guarantee the color of image pixel is not shifted. While working for image processing software, color conversion (or color-space conversion) is the very fundamental skill we have to face first.
