Draw on a photo

A photo shows what is there. A drawing shows what to look at. Circle the crack, point at the joint, highlight the area concerned: whoever receives the report understands in a second instead of rereading the comment.

Opening the editor

1. Open a viewpoint and click a photo to show it large.
2. Click Draw.

The tools

Tool	Use
Pen	Free, opaque stroke. The basic tool for circling and underlining
Highlighter	Semi-transparent free stroke, to cover an area without hiding what is underneath
Circle	Drag to define an ellipse
Arrow	Drag from the start towards the tip
Eraser	Removes a whole stroke in one click, not just the part you touch

Two settings go with the tools:

• Colour: the PhotoReport palette, the same one used for annotations.
• Thickness: a slider setting the stroke width.

Correcting

• Undo last stroke and Redo step back and forward one at a time.
• Clear all removes every stroke in the drawing, after confirmation. This is irreversible.

Nothing is saved until you click Save.

The drawing stays editable

The drawing is not merged into the photo. It is kept separately, as strokes, which has two useful consequences:

• You can reopen the editor later and carry on, erase or add.
• The original photo stays intact. The ZIP archive of your reports contains both.

The format is shared across every platform: a drawing made in the browser appears identically on iPhone, iPad and Android, and in exported reports.

Note

A photo annotated on iOS before version 2026.9 uses the old drawing format, which the browser cannot edit. A message tells you so. Open the photo once in the iOS app: it is converted automatically to the shared format, and becomes editable everywhere again.

Drawing or annotating?

The two complement each other:

• A viewpoint locates the observation on the plan and carries the written comment.
• A drawing pins down, inside a photo, the exact spot being discussed.

On a viewpoint with several photos, draw at least on the one serving as the main evidence.
