Technical note

SID to AI: what carries over and what does not

SID is made of pixels and AI stores geometry, so the conversion traces the image into paths. Once traced, the artwork scales to any size without softening, which is the point of the exercise. It is a reconstruction rather than the original drawing: curves are fitted to the pixel edges, so the cleaner and sharper the source, the closer the paths follow what the designer intended. A line in a SID image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the SID does not survive as colour in the AI.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see SID data has GIS software. reaConverter renders it to AI for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to AI with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

Client demanded PNGs but sent AI files ‘because you have Adobe, right?’ Jokes on them—reaConverter handled it while I sipped my coffee.
