PptxGenJS Helpers

When To Read This

Read this file when you need helper API details, command examples for the bundled Python scripts, or dependency notes for a slide-generation task.

Helper Modules

autoFontSize(textOrRuns, fontFace, opts): Pick a font size that fits a fixed box.
calcTextBox(fontSizePt, opts): Estimate text-box geometry from font size and content.
calcTextBoxHeightSimple(fontSizePt, numLines, leading?, padding?): Quick text height estimate.
imageSizingCrop(pathOrData, x, y, w, h): Center-crop an image into a target box.
imageSizingContain(pathOrData, x, y, w, h): Fit an image fully inside a target box.
svgToDataUri(svgString): Convert an SVG string into an embeddable data URI.
latexToSvgDataUri(texString): Render LaTeX to SVG for crisp equations.
getImageDimensions(pathOrData): Read image width, height, type, and aspect ratio.
safeOuterShadow(...): Build a safe outer-shadow config for PowerPoint output.
codeToRuns(source, language): Convert source code into rich-text runs for addText.
warnIfSlideHasOverlaps(slide, pptx): Emit overlap warnings for diagnostics.
warnIfSlideElementsOutOfBounds(slide, pptx): Emit boundary warnings for diagnostics.
alignSlideElements(slide, indices, alignment): Align selected elements precisely.
distributeSlideElements(slide, indices, direction): Evenly space selected elements.

Dependency Notes

JavaScript helpers expect these packages when you use the corresponding features:

Core authoring: pptxgenjs
Text measurement: skia-canvas, linebreak, fontkit
Syntax highlighting: prismjs
LaTeX rendering: mathjax-full

Python scripts expect these packages:

Pillow
pdf2image
python-pptx
numpy

System tools used by the Python scripts:

soffice / LibreOffice for PPTX to PDF conversion
Poppler tools for PDF size/raster support used by pdf2image
fc-list for font inspection
Optional rasterization tools for ensure_raster_image.py: Inkscape, ImageMagick, Ghostscript, heif-convert, JxrDecApp

Script Notes

render_slides.py: Convert a deck to PNGs. Good for visual review and diffing.
slides_test.py: Add a gray border outside the original canvas, render, and check whether any content leaks into the border.
create_montage.py: Combine multiple rendered slide images into a single overview image.
detect_font.py: Distinguish between fonts that are missing entirely and fonts that are installed but substituted during rendering.
ensure_raster_image.py: Produce a PNG from common vector or unusual raster formats so you can inspect or place the asset easily.

Practical Rules

Default to LAYOUT_WIDE unless the source material says otherwise.
Set font families explicitly before measuring text.
Use valign: "top" for content boxes that may grow.
Prefer native PowerPoint charts over rendered images when the chart is simple and likely to be edited later.
Use SVG instead of PNG for diagrams whenever possible.
