ISCC - SVG Processing

SVG handling module.

svg_rasterize(fp, max_size=_SVG_MAX_RENDER_SIZE)

Rasterize an SVG file to a PIL Image via resvg.

Renders at native size when it fits within max_size, caps oversized SVGs.

Parameters:

Name	Type	Description	Default
fp		Filepath to SVG file.	required
max_size		Maximum pixel dimension on any side (default 4096).	_SVG_MAX_RENDER_SIZE

Returns:

Type	Description
	Rasterized image as PIL Image object

svg_meta_extract(fp)

Extract metadata from SVG file.

Extracts from ISCC namespace in RDF, SVG native elements, and Dublin Core/CC in RDF, with ISCC namespace taking highest priority.

Parameters:

Name	Type	Description	Default
fp		Filepath to SVG file.	required

Returns:

Type	Description
	Metadata mapped to IsccMeta schema

svg_meta_embed(fp, meta)

Embed metadata into a copy of the SVG file.

Writes to SVG native elements (title, desc) and RDF/Dublin Core in the metadata element, mirroring the image module's dual ISCC+DC strategy.

Parameters:

Name	Type	Description	Default
fp		Filepath to source SVG file.	required
meta		Metadata to embed into SVG.	required

Returns:

Type	Description
	Filepath to the new SVG file with updated metadata

svg_meta_delete(fp)

Delete all metadata from SVG file (in place).

Removes title, desc, and metadata elements from the SVG XML.

Parameters:

Name	Type	Description	Default
fp		Filepath to SVG file.	required

svg_thumbnail(fp, img=None, **options)

Create a thumbnail for an SVG file.

Parameters:

Name	Type	Description	Default
fp		Filepath to SVG file.	required
img		Pre-rasterized PIL Image to reuse (avoids re-rasterization).	None
options		Keyword arguments forwarded to sdk_opts: image_thumbnail_size - Size of the larger side of the thumbnail in pixels. Default: 128	{}

Returns:

Type	Description
	Thumbnail image as PIL Image object
