Converts pixels from one resolution to another.

pixelToNewDpi(pixels: number, oldDpi: number, newDpi: number)

Parameter	Type	Description
pixels	number	The value to convert.
oldDpi	number	The current dpi (dots per inch) resolution.
newDpi	number	The new dpi (dots per inch) resolution.

Examples

Shows how to use convert points to pixels with default and custom resolution.

let doc = new aw.Document();
let builder = new aw.DocumentBuilder(doc);

// Define the size of the top margin of this section in pixels, according to a custom DPI.
const myDpi = 192;

let pageSetup = builder.pageSetup;
pageSetup.topMargin = aw.ConvertUtil.pixelToPoint(100, myDpi);

expect(pageSetup.topMargin).toBeCloseTo(37.5, 2);

// At the default DPI of 96, a pixel is 0.75 points.
expect(aw.ConvertUtil.pixelToPoint(1)).toEqual(0.75);

builder.writeln(`This Text is ${pageSetup.topMargin} points/${aw.ConvertUtil.pointToPixel(pageSetup.topMargin, myDpi)} ` +
        `pixels (at a DPI of ${myDpi}) from the top of the page.`);

// Set a new DPI and adjust the top margin value accordingly.
const newDpi = 300;
pageSetup.topMargin = aw.ConvertUtil.pixelToNewDpi(pageSetup.topMargin, myDpi, newDpi);
expect(pageSetup.topMargin).toBeCloseTo(59.0, 2);

builder.writeln(`At a DPI of ${newDpi}, the text is now ${pageSetup.topMargin} points/${aw.ConvertUtil.pointToPixel(pageSetup.topMargin, myDpi)} ` +
        "pixels from the top of the page.");
