Image¶

The IMAGE entity (DXF Reference) represents a raster image, the image file itself is not embedded into the DXF file, it is always a separated file. The IMAGE entity is like a block reference, it can be used to add the image multiple times at different locations with different scale and rotation angles. Every IMAGE entity requires an image definition, see entity ImageDef. Ezdxf creates only images in the xy-plan, it’s possible to place images in 3D space, therefore the Image.dxf.u_pixel and the Image.dxf.v_pixel vectors has to be set accordingly.

Subclass of	`ezdxf.entities.DXFGraphic`
DXF type	`'IMAGE'`
Factory function	`ezdxf.layouts.BaseLayout.add_image()`
Inherited DXF attributes	Common graphical DXF attributes
Required DXF version	DXF R2000 (`'AC1015'`)

Warning

Do not instantiate entity classes by yourself - always use the provided factory functions!

class ezdxf.entities.Image¶

dxf.insert¶: Insertion point, lower left corner of the image (3D Point in WCS).

dxf.u_pixel¶: U-vector of a single pixel as (x, y, z) tuple. This vector points along the visual bottom of the image, starting at the insertion point.

dxf.v_pixel¶: V-vector of a single pixel as (x, y, z) tuple. This vector points along the visual left side of the image, starting at the insertion point.

dxf.image_size¶: Image size in pixels as (x, y) tuple

dxf.image_def_handle¶: Handle to the image definition entity, see ImageDef

dxf.flags¶

`Image.SHOW_IMAGE`	1	Show image
`Image.SHOW_WHEN_NOT_ALIGNED`	2	Show image when not aligned with screen
`Image.USE_CLIPPING_BOUNDARY`	4	Use clipping boundary
`Image.USE_TRANSPARENCY`	8	Transparency is on

dxf.clipping¶

Clipping state:

0	clipping off
1	clipping on

dxf.brightness¶: Brightness value in the range [0, 100], default is 50

dxf.contrast¶: Contrast value in the range [0, 100], default is 50

dxf.fade¶: Fade value in the range [0, 100], default is 0

dxf.clipping_boundary_type¶

1	Rectangular
2	Polygonal

dxf.count_boundary_points¶: Number of clip boundary vertices, this attribute is maintained by ezdxf.

dxf.clip_mode¶

0	Outside
1	Inside

requires DXF R2010 or newer

boundary_path¶

Returns the boundray path in raw form in pixel coordinates.

A list of vertices as pixel coordinates, Two vertices describe a rectangle, lower left corner is (-0.5, -0.5) and upper right corner is (ImageSizeX-0.5, ImageSizeY-0.5), more than two vertices is a polygon as clipping path. All vertices as pixel coordinates. (read/write)

image_def¶: Returns the associated IMAGEDEF entity, see ImageDef.

reset_boundary_path() → None¶: Reset boundary path to the default rectangle [(-0.5, -0.5), (ImageSizeX-0.5, ImageSizeY-0.5)].

set_boundary_path(vertices: Iterable[UVec]) → None¶: Set boundary path to vertices. Two vertices describe a rectangle (lower left and upper right corner), more than two vertices is a polygon as clipping path.

pixel_boundary_path() → list[Vec2]¶: Returns the boundary path as closed loop in pixel coordinates. Resolves the simple form of two vertices as a rectangle. The image coordinate system has an inverted y-axis and the top-left corner is (0, 0).

Changed in version 1.2.0: renamed from boundray_path_ocs()

boundary_path_wcs() → list[Vec3]¶

Returns the boundary/clipping path in WCS coordinates.

It’s recommended to acquire the clipping path as Path object by the make_path() function:

from ezdxf.path import make_path

image = ...  # get image entity
clipping_path = make_path(image)

transform(m: Matrix44) → Self¶: Transform IMAGE entity by transformation matrix m inplace.
