Mirror

Mirrors an image along the specified axis, producing a horizontally, vertically, or doubly mirrored result.

Remarks

The Mirror command creates a mirror image of the input by flipping it along the selected axis. This is useful for correcting images that were scanned or photographed in reverse, for preparing images for double-sided printing, or for any scenario where a mirrored version of the image is required.

How Mirror Works

• The command supports three mirroring modes, controlled by the 'Axis' property:

  • Horizontal: Flips the image around a horizontal line through its center, producing an upside-down result.
  • Vertical: Flips the image around a vertical line through its center, producing a left-right mirror (like a physical mirror).
  • Both: Flips the image around both axes, equivalent to a 180° rotation.

• The operation is performed in-place and supports all common pixel formats, including binary, grayscale, color, and images with alpha channels.

Supported Pixel Formats

All pixel formats are supported, including:

• Pixel1bppIndexed
• Pixel8bppGrayscale
• Pixel8bppIndexed
• Pixel24bppBgr
• Pixel32bppBgr
• Pixel32bppBgra
• Pixel32bppCmyk
• Pixel16bppGrayscale
• Pixel16bppGrayscaleAlpha

Configuration and Usage

• Set the 'Axis' property to control the direction of mirroring.
• Use this command in an IP Profile or as part of a processing pipeline to correct orientation or create mirrored images for special applications.
• No additional configuration is required; the operation is fast and lossless.

Diagnostics

The Mirror command does not generate diagnostic images or logs, as the operation is deterministic and visually verifiable.

Properties

Name	Type		Description
General
Axis	Axis	►	The axis on which the image should be mirrored. DefaultHorizontal Can be one of the following values: Name Value Description Horizontal 0 Mirror around a horizontal line through the center of the image. Vertical 1 Mirror around a vertical line through the center of the image - like a physical mirror. Both 2 Mirror around both axis. The 'Axis' property determines the direction in which the image will be flipped: Horizontal: The image is mirrored around a horizontal axis passing through its center. The top and bottom are swapped, producing an upside-down image. This is useful for correcting images scanned upside-down or for special effects. Vertical: The image is mirrored around a vertical axis passing through its center. The left and right sides are swapped, producing a true mirror image (as seen in a physical mirror). This is commonly used to correct images that were scanned or photographed in reverse. Both: The image is mirrored around both axes, equivalent to a 180° rotation. The result is both upside-down and left-right reversed.
Command Info
Command Type	String	►	The display name of this image processing command. The 'Command Type Name' property shows the user-friendly name of the IP Command as it appears in the Grooper UI. This helps users identify which command is being configured or executed, especially when working with IP Profiles containing multiple commands. This property is read-only and is automatically set based on the command's type.
Supported Pixel Formats	String	►	The pixel formats supported by this command. The 'Supported Pixel Formats' property lists the image pixel formats that the IP Command can process. If an image does not match one of these formats, the command will be skipped for that image. By default, all pixel formats are supported unless a derived command restricts this list. Example formats include Pixel8bppGrayscale, Pixel24bppBgr, and Pixel1bppIndexed. Use this property to verify compatibility when building IP Profiles or troubleshooting why a command did not execute.
