✨ NAME ✨

Image::ExifTool::Plot — bestie, this is the module that plots your tag values in SVG format 💅 (and yes, it's part of the User Contributed Perl Documentation, we love a community moment 🫶)

🌸 DESCRIPTION 🌸

Okay so picture this: you've got ExifTool tag info, right? And you want it to look pretty. This module outputs plots in SVG format based on ExifTool tag information. It's giving data-viz main character energy, no cap ✨

🎀 METHODS 🎀

💖 new

Create a new Plot object. Fresh plot, fresh start, literally iconic.

$plot = Image::ExifTool::Plot->new;

🦋 Settings

Change plot settings. This is where you customize the vibe check of your whole plot 🌈

Inputs:

  1. Plot object reference
  2. Comma-delimited string of options

Options: (bestie, there are a LOT, but every single one matters, so here we go 💜)

  • "Type=Line" — plot type, and your choices are Line, Scatter or Histogram
  • "Style=Line" — data style, pick from Line, Marker and/or Fill
  • "NBins=20" — number of bins for histogram plot
  • "Size=800 600" — width,height of output image
  • "Margin=60 15 15 30" — left,top,right,bottom margins around plot area
  • "Legend=0 0" — x,y offset to shift plot legend
  • "TxtPad=10 10" — padding between text and x,y scale
  • "LineSpacing=20" — spacing between text lines
  • "Stroke=1" — plot stroke width and marker-size scaling factor
  • Title, XLabel, YLabel — plot title and x/y axis labels (no default, so you do have to set these yourself 🙈)
  • XMin, XMax — x axis minimum/maximum (autoscaling if not set, slay)
  • YMin, YMax — y axis minimum/maximum
  • Multi — number of columns when drawing multiple plots, followed optional number of datasets for each plot (1 by default) using any separator
  • Split — flag to split strings of numbers into lists (> 1 to split into lists of N items)
  • "Grid=darkgray" — grid color
  • "Text=black" — color of text and plot border
  • "Bkg=" — background color (default is transparent, very chic ✨)
  • "Cols=red green blue black orange gray fuchsia brown turquoise gold" — colors for plot data
  • "Marks=circle square triangle diamond star plus pentagon left down right" — marker-shape names for each dataset

🧚 AddPoints

Add points to be plotted. Gotta have data to plot, obviously 💀

Inputs:

  1. Plot object reference
  2. Tag information hash reference from ExifTool
  3. List of tag keys to plot

👑 Draw

Draw the SVG plot to the specified output file. The moment we've all been waiting for 💅

Inputs:

  1. Plot object reference
  2. Output file reference

Notes:

On return, the Plot Error and Warn members contain error or warning strings if there were any problems. If an Error is set, then the output SVG is invalid — so like, actually check those, bestie, fr fr 😭
