Allow custom Layout sizes (ex: A3)

[itskun]

I would like to see in your wonderful project such new features:

• A3 layout format
• images in table cells
• text multiformatting in single table cells

Hi @itskun ,

You can now specify any layout size you want using the existing setLayout() method.

Just pass a name/width/height and all the Slides in the that Presentation will be your layout size:

pptx.setLayout({ name:'A3', width:16.5, height:11.7 });

Thank you, @gitbrent !
There is issue, with this - when I'm trying to set layout, there appears a message:

PowerPoint found unreadable content in Presentation.pptx. Do you want to recover the contects of this presentation? If you trust the source of this presentation, click Yes.

So when I changed 'LAYOUT_16x9' line 92 at pptgen.js
gObjPptx.pptLayout = LAYOUTS['LAYOUT_16x9'];
to another layout name, presentation file opened without errors.

Hi @itskun ,

Sure enough there was an issue with the name value in the Slide Layout XML tags.

It's been fixed now and an A3 opens for me in PowerPoint without errors now.

I haved same bug (PowerPoint need recover) when I want set A4 layout.

pptx.setLayout({ name: 'A4', width:10.834645669, height:7.5 });

When I'm trying to set layout, there appears a message:

PowerPoint found unreadable content in Presentation.pptx. Do you want to recover the contects of this presentation? If you trust the source of this presentation, click Yes.

I solved it, by change two lines at pptgen.js

/*2620*/ LAYOUTS['LAYOUT_USER'].width  = Number(inLayout.width ) * EMU;
/*2621*/ LAYOUTS['LAYOUT_USER'].height = Number(inLayout.height) * EMU;

to this

/*2620*/ LAYOUTS['LAYOUT_USER'].width  = Math.round(Number(inLayout.width ) * EMU);
/*2621*/ LAYOUTS['LAYOUT_USER'].height = Math.round(Number(inLayout.height) * EMU);

The width or the height must be an integer not a float.

Hi @badlee ,

Thanks for the info! I've added rounding to the width and height so this won't be an issue going forward.
