Enhancement adjustments

Every cleanup option — deskew, denoise, binarize, crop, line/hole removal, color dropout, and color mode.

This is the complete reference for every enhancement control in Scanix Desktop. The same cleanups live in two lanes — the Viewer Enhancements panel (interactive, per page) and the template Scan & Image tab (automatic, every page) — and the tables below give each option's exact label, its values, and its default. For when and why to use each lane, see Image enhancement; for the capture side of the template tab, see Scan settings.

Two lanes, shared cleanups

The Enhancements panel (Viewer, right sidebar) and the template Scan & Image tab expose overlapping controls. Their labels differ slightly because one is hands-on and one is a saved configuration. Each table below notes which lane it documents.

Viewer Enhancements panel

Open a document, click Enhance in the top toolbar (or pick the Enhance tab in the right sidebar) to reveal the Enhancements panel. Every control updates a live preview; nothing is written to disk until you press the apply button. The panel is split into collapsible sections.

Transform

Manual geometry. These buttons act on the page in front of you immediately in the preview.

Control	Action	Default
Rotate 90° CCW	Rotate the page 90° counter-clockwise.	0°
Rotate 90° CW	Rotate the page 90° clockwise.	0°
180°	Rotate the page 180°.	0°
Flip Horizontal	Mirror the page left-to-right.	Off
Flip Vertical	Mirror the page top-to-bottom.	Off

When a rotation is set, the panel shows the current angle (for example, Rotation: 90°).

Auto-Corrections

Automatic geometry toggles. All three are off by default.

Control	What it does	Default
Auto-deskew	Intended to straighten a tilted page.	Off
Auto-rotate	Detect and correct page orientation.	Off
Auto-crop	Trim page borders conservatively.	Off

Auto-deskew in the Viewer panel is not yet active

The Auto-deskew toggle in the Viewer Enhancements panel is present but does not yet straighten the page. If you need automatic deskew, turn it on in the template's Scan & Image tab instead (the Auto-deskew (straighten tilted pages) checkbox), where it runs on import. The manual Transform rotate and flip buttons work normally.

Image Enhancement

Pixel cleanups that recolor the image without changing its size.

Control	Values	Default
Sharpen	On / Off	Off
Edge Enhance	On / Off	Off
Denoise	Off, Fast, Median, Bilateral	Off
Despeckle	On / Off	Off
Auto Level	On / Off	Off
Invert	On / Off	Off
Sepia	On / Off	Off
Binarize (B&W)	On / Off	Off

The Denoise selector replaces a plain on/off toggle with four modes:

Denoise mode	Use it for
Off	No denoising.
Fast	A quick, light pass.
Median	Salt-and-pepper speckle.
Bilateral	Noise reduction that preserves edges.

When Binarize (B&W) is on (and the Threshold override is off), a Method selector appears:

Binarize method	Notes	Default
Fixed	A single fixed cutoff.	Default
Otsu	Picks the cutoff automatically from the whole page.	—
Sauvola	Adapts the cutoff locally — good for uneven lighting.	—

The Threshold control sits in the same section. It is Off by default; switch it On to expose a slider.

Control	Range	When On	Default
Threshold	0–255	Sets an explicit black/white cutoff (starts at 128)	Off

When Threshold is On, its explicit value takes precedence over the Method selector above.

Morphology

Post-binarize shape cleanup. This section is collapsed by default.

Mode	Effect	Default
Off	No morphology.	Default
Erode	Thin strokes.	—
Dilate	Thicken strokes.	—
Open	Remove small speckle.	—
Close	Repair broken strokes.	—

Structural Cleanup

Removes form furniture. This section is collapsed by default; all toggles are off.

Control	What it removes	Default
Remove horizontal lines	Horizontal ruled lines.	Off
Remove vertical lines	Vertical ruled lines.	Off
Remove underlines	Underlines beneath text.	Off
Remove border	A surrounding page border.	Off

The panel notes: Auto-binarizes if upstream Binarize is off. Each of these toggles works on its own — you do not have to turn on Binarize (B&W) first.

Adjustments

Continuous sliders. Double-click a slider's value to reset it to its default.

Slider	Range	Default
Brightness	-1 to 1	0
Contrast	-1 to 1	0
Saturation	-1 to 1	0
Gamma	0.1 to 5.0	1.0

Color Mode

A three-way switch for the page's output color.

Option	Meaning	Default
Color	Keep full color.	Default
Gray	Convert to grayscale.	—
B&W	Convert to black & white.	—

Color Dropout

Drops one ink color so a form's pre-printed lines and boxes disappear, leaving the entered data. Collapsed by default.

Option	Default
None	Default
Red	—
Green	—
Blue	—

Panel footer and apply

Control	What it does
Undo	Step back one change (also Ctrl+Z).
Redo	Step forward one change (also Ctrl+Y).
Reset	Clear all changes back to defaults.
Apply	Commit the enhancement when the page is not yet recognized.
Apply & Re-OCR	Commit the enhancement and re-read the page when it already has OCR text.

The eye / eye-off button in the panel header compares the result against the original (tooltip Show original / Show enhanced). The apply button only appears once you have changed at least one control. For why the label switches between Apply and Apply & Re-OCR, see Image enhancement.

Template Scan & Image tab

When you build a template, its Scan & Image tab pre-decides the cleanups that run automatically on every page captured or imported with that template. The controls are grouped into cards; every option below is off (or set to its first value) by default. The capture controls (Resolution, Color Mode, Paper Source, Duplex) are covered in Scan settings.

Auto-Corrections (template)

Control	What it does	Default
Auto-deskew (straighten tilted pages)	Straighten a tilted page on import.	Off
Auto-rotate (detect page orientation)	Detect and correct page orientation.	Off
Auto-crop (trim borders)	Trim page borders conservatively.	Off
Remove blank pages	Discard pages detected as blank.	Off
Crop white background (keep only content)	Trim all surrounding white to keep just the content block.	Off
ID card detection (crop / split front + back)	Auto-detect ID cards and crop / stack / split them at import.	Off

Auto-crop vs Crop white background

These are two intensities of the same idea. Auto-crop keeps a normal document's margins and only trims a large white border; Crop white background removes all surrounding white to keep just the content — ideal for a card or receipt on a big white page.

When ID card detection is on, it owns cropping — Auto-crop and Crop white background are disabled (tooltip Handled by ID-card detection — turn it off to use the general crop) — and a follow-up selector controls how multiple cards are handled:

When multiple cards are detected	Result	Default
Combine front + back onto one page	Stack both sides onto a single page.	Default
Keep front + back on their own pages	Each side stays on its own page.	—
Split each card onto its own page (bed scans)	Split each detected card onto its own page.	—

Image Enhancement (template)

Control	Values	Default
Color Mode	Color, Grayscale, Black & White	Color
Binarize (convert to black & white)	On / Off	Off
Denoise (reduce noise)	On / Off	Off
Sharpen	On / Off	Off
Despeckle	On / Off	Off
Contrast	-100 to 100	0
Brightness	-100 to 100	0

Form Processing (template)

Control	What it does	Values	Default
Line removal (remove ruled lines)	Strip ruled lines from forms.	On / Off	Off
Hole removal (remove punch holes)	Erase binder punch holes.	On / Off	Off
Text enhance (improve OCR accuracy)	Sharpen text for recognition.	On / Off	Off
Bleed-through reduction	Suppress ink showing through from the back.	On / Off	Off
Crop borders (remove black edges)	Trim black scanner edges.	On / Off	Off
Color Dropout	Drop one ink color from a form.	None, Red, Green, Blue	None
