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`);
