Trying to utilize webkitBackingStorePixelRatio on the HTML canvas has presented a challenge.
An example such as:
context.webkitBackingStorePixelRatio
generates a type error in VSCode, indicating that the webkitBackingStorePixelRatio property is undefined. To address this issue, I made adjustments to the CanvasRenderingContext2D interface in lib.dom.t.ts as shown below:
interface CanvasRenderingContext2D extends CanvasCompositing, CanvasDrawImage, CanvasDrawPath, CanvasFillStrokeStyles, CanvasFilters, CanvasImageData, CanvasImageSmoothing, CanvasPath, CanvasPathDrawingStyles, CanvasRect, CanvasShadowStyles, CanvasState, CanvasText, CanvasTextDrawingStyles, CanvasTransform, CanvasUserInterface {
mozBackingStorePixelRatio: any;
msBackingStorePixelRatio: any;
oBackingStorePixelRatio: any;
backingStorePixelRatio: any;
webkitBackingStorePixelRatio: any;
readonly canvas: HTMLCanvasElement;
}
This adjustment successfully resolves the error in VSCode.
However, when compiling using tsc, the same error persists:
Property 'webkitBackingStorePixelRatio' does not exist on type 'CanvasRenderingContext2D'.Is there a method to instruct tsc from the command line to use lib.dom.d.ts in the same way as VSCode does, thus preventing this error? Alternatively, is this approach unadvisable?
