Configuration
Initial Setup
The Filerobot Image Editor requires minimal configuration to start using, but offers extensive customization options for laboratory-specific workflows.
Navigate to the section where you want to add image editing capability and click Add Widget
Select Filerobot Image Editor from the Office category in the widget library
Upload your initial image or start with a blank canvas to begin editing
Required Settings
The Filerobot Image Editor works with default settings out of the box. No required configuration is needed for basic image editing functionality.
Optional Settings
Default Export Format: Set the preferred image format (PNG, JPEG, or WebP) for exported images. PNG is recommended for scientific images requiring lossless quality
Quality Settings: Configure default JPEG quality (1-100) and WebP quality settings for exported files
Watermark Template: Pre-configure organization watermarks (logo, text, or both) that can be quickly applied to images
Color Palette: Define custom color presets for annotations to match your laboratory's documentation standards
Maximum Image Size: Set limits on image dimensions or file size for performance optimization
Enable Features: Toggle specific editing features on/off based on user permissions or workflow requirements
The widget uses default values optimized for scientific image editing. Most laboratories can start using the editor immediately without custom configuration.
Advanced Configuration
For specialized laboratory workflows or compliance requirements:
Access Advanced Settings from the widget configuration panel
Configure State Management settings:
Enable automatic state saving to preserve editing sessions
Set auto-save intervals for long editing sessions
Configure state export format for sharing editing templates
Set up Compliance Features:
Enable edit history logging for FDA 21 CFR Part 11 compliance
Configure audit trail settings for regulated environments
Set up digital signature requirements for finalized images
Define User Interface Preferences:
Customize toolbar layout and available tools
Set default zoom levels and canvas size
Configure touch sensitivity for tablet users
Click Save Configuration to apply all advanced settings
Advanced configuration options affect how users interact with images and may impact compliance workflows. Test thoroughly in a development environment before deploying to production.

Click Download to save the edited image to your device or Save to Labii to attach directly to your record
State Export/Import (Experimental)
A powerful feature for collaborative editing and workflow templates:
After editing an image, click the Export State button in the toolbar
Save the exported JSON file containing all editing information (annotations, adjustments, filters)
To resume editing later or share with colleagues, click Import State and select the saved JSON file
The editor will restore the exact editing session, allowing you to continue where you left off or replicate edits on similar images
State export is particularly useful for creating standardized annotation templates for repetitive experiments (e.g., gel lanes, microscopy grids) or training team members on proper image documentation.

Best Practices
Data Organization
Structure your image documentation with consistent naming conventions for easy retrieval (e.g., "Gel_Experiment123_Lane1-8_2024-03-15")
Use descriptive annotations that clearly identify important features (molecular weights, sample IDs, regions of interest)
Organize related images within the same record section for contextual documentation of experimental workflows
Add metadata in the caption to describe experimental conditions, equipment settings, and acquisition parameters
Image Quality and Integrity
Always work with high-resolution originals and save edited versions separately to maintain source data
Use PNG format for scientific images that require lossless quality (gels, Western blots, microscopy)
Enable live comparison before finalizing edits to verify that adjustments don't obscure important data
Document all significant edits in the record notes to maintain transparency for peer review and audits
Export and save the editing state for complex annotations that may need revision or replication
Annotation Best Practices
Use consistent color coding across your experiments (e.g., red for positive results, blue for controls)
Apply text annotations with sufficient contrast for readability in both digital and printed formats
Add scale bars to microscopy images to provide dimensional context
Use arrows and shapes sparingly to avoid cluttering the image while highlighting key features
Create annotation templates using state export for standardized documentation across similar experiments
Performance Optimization
Resize large images to appropriate dimensions before extensive editing to improve responsiveness
Use selective editing rather than applying global filters when only specific regions need adjustment
Clear editing history periodically for very long editing sessions to free up memory
For batch operations, use exported state templates to quickly apply consistent edits to multiple images
Common Pitfalls to Avoid
Avoid over-editing: Excessive filters or adjustments can obscure original data and raise questions about data integrity
Avoid destructive edits: Always preserve original images; use the editor's non-destructive workflow with history management
Avoid low-quality exports: Using high JPEG compression for publication figures can introduce artifacts in scientific images
Instead: Use PNG for scientific images, maintain originals separately, and document all adjustments transparently
Avoid ambiguous annotations: Unclear labels or unmarked regions can confuse collaborators and reviewers
Instead: Use clear, descriptive text with appropriate colors and positioning for all annotations
Maintenance and Troubleshooting
Regularly review image file sizes to ensure storage efficiency without compromising quality
Monitor export settings to maintain consistency across your documentation
If the editor performs slowly, reduce image dimensions or close other browser tabs to free up memory
If annotations appear pixelated, increase the canvas resolution in configuration settings
For touch device issues, calibrate touch sensitivity in advanced settings or use a stylus for precision work
