Annotation & Markup
Crosscheck includes a powerful annotation editor. After capturing a screenshot, you can mark up the image with drawings, text, arrows, shapes, and blur effects before saving or sharing it. Annotations are also available when viewing existing screenshots in the dashboard.
Annotation Tools
The toolbar provides the following tools. Each tool can be combined with the color picker and adjusted for stroke width.
| Tool | Description | Usage |
|---|---|---|
| Freehand Drawing (Pen) | Draw freely on the canvas with your cursor | Select the pen tool, choose a color, and draw directly on the screenshot |
| Text Box | Add text annotations anywhere on the image | Click on the canvas to place a text box, then type your annotation |
| Arrow / Line | Draw straight arrows or lines to point at specific areas | Click and drag from the start point to the end point |
| Rectangle | Draw rectangular outlines or filled shapes | Click and drag to define the rectangle area |
| Circle / Ellipse | Draw circular or elliptical outlines | Click and drag to define the circle size and position |
| Blur / Pixelate | Obscure sensitive information such as passwords or PII | Select the blur tool and drag over the area you want to hide |
| Color Picker | Change the stroke and fill color for all drawing tools | Click the color swatch in the toolbar and select a new color |
| Undo / Redo | Step backward or forward through your annotation history | Click the undo or redo button, or use keyboard shortcuts |
