Image Workbench

Introduction
The Image Workbench manages different types of bitmap images, and allows you to open them in FreeCAD.

Currently, the module supports opening BMP, JPG, PNG, and XPM file formats.

Tools
Image Import: import an image on a plane in the 3D view.

Features

 * The imported image can be attached like a Sketch to one of the main planes XY, XZ, or YZ, with a positive or negative offset.
 * A major use of this tool is tracing over the image, in order to produce a contour that can be used to generate a new part.
 * The image is imported with relation of 1 pixel equals to 1 millimeter.
 * The recommendation is to have the imported image at a reasonable resolution.
 * The image can be scaled by editing the "XSize" and "YSize" values in the Property editor.
 * The image can be moved in the 3D view by editing the in the Property editor.
 * The image can be rotated around any axis by using the Property editor.

Workflow
Tracing with sketcher elements over an image works best if the image has a small (negative) offset to the sketch plane.

You can set an offset of -0,1 mm at import or later by editing the placement of the image.
