NativeScript Image Colors

npm npm

NativeScript image colors

Example

import { ImageColors  } from 'nativescript-image-colors';



let image = page.getViewById<Image>(`image`);
colors = ImageColors.getColorPalette(image);

colors.color1;
colors.color2;
colors.color3;

Usage

returns a ColorPalette that has 3 color properties color1, color2, and color3. the Color Palette also contains a AndroidPalette and IosPalette object properties. The AndroidPalette has properties that correspond with https://developer.android.com/reference/android/support/v7/graphics/Palette.html. The IosPalette object corresponds with the SLColorArt object from the https://cocoapods.org/?q=ColorArt object. ColorPalette is a composite of these two so you don't have to do null and platform checks. please note the colors will not be consistent between platforms since the algorithms used are different.

Libraries used:

Android: https://developer.android.com/reference/android/support/v7/graphics/Palette.html iOS: https://github.com/panicinc/ColorArt

nativescript-image-colors's Issues

Javascript version

My nativescript project is in javascript and i need to extract the colors from an image.n Can you kindly give me the javascript code, instead of typescript?

Error -> undefined is not an object (evaluating 'image.ios.image')

I tried to use the module with two images, 1st I took an image with the camera module and 2nd I loaded an image from the filesystem. Both times I can display the image in my view, and see in my console.log : Image(14) so I assume the image is loaded properly.

Bot times I get the following error:

Error -> undefined is not an object (evaluating 'image.ios.image')

1st with camera:

      camera.takePicture(cameraOptions)
          .then( (imageAsset) => {
              // Using the image from camera
              console.log("imageAsset", imageAsset);
              this.image = new Image();
              this.image.src = imageAsset;
              console.log("imageAsset", imageAsset.nativeImage)
              console.log("IMAGE from CAMERA", this.image)
              const colors = ImageColors.getColorPalette(this.image)
              console.log("FAILS:", colors) // undefined is not an object (evaluating 'image.ios.image')

2nd from file:

              const folder: Folder = <Folder> knownFolders.currentApp();
              const folderPath: string = path.join(folder.path, "assets/images/test.png");
              const imageFromLocalFile: ImageSource = <ImageSource> fromFile(folderPath);
              this.image = new Image();
              this.image.src = imageFromLocalFile;
              console.log("IMAGE from FILE", this.image)
              const colors = ImageColors.getColorPalette(this.image)
              console.log("FAILS:", colors)
