You can directly change the xmlObject.
function setPageNumStyle(slide, style){ let pageNumElement = slide.powerPointFactory.pptFactory.slideFactory.content[`ppt/slides/${slide.name}.xml`]['p:sld']['p:cSld'][0]['p:spTree'][0]['p:sp'][0]; let fld = pageNumElement['p:txBody'][0]['a:p'][0]['a:fld'][0]; let styleData = {$: fld['a:rPr'][0].$}; if(style.fontSize !== undefined) styleData.$.sz = style.fontSize * 100; if(style.fontBold !== undefined) styleData.$.b = style.fontBold ? 1 : 0; if(style.fontItalic !== undefined) styleData.$.i = style.fontItalic ? 1 : 0; if(style.fontUnderline !== undefined) styleData.$.u = style.fontUnderline ? 'sng' : 0; if(style.textColor) styleData['a:solidFill'] = [{'a:srgbClr': [{$: {val: style.textColor}}]}]; if(style.fontFace){ let fontFaceAttribute = [{$: {typeface: style.fontFace, pitchFamily: 0, charset: 0}}]; styleData['a:latin'] = fontFaceAttribute; styleData['a:cs'] = fontFaceAttribute; } fld['a:rPr'][0] = styleData; }
Here's how the function works.
const PPTX = require('nodejs-pptx'); let pptx = new PPTX.Composer(); await pptx.compose(async pres => { await pres.addSlide(slide => { setPageNumStyle(slide, { fontFace: 'Abadi', fontSize: 15, fontBold: true, fontItalic: false, fontUnderline: true, textColor: '000000', }); }); }); await pptx.save(`./set-page-num-style.pptx`);
