Expand description
Optional metadata to be passed into the PDF factory function.
Fields§
§title: String
The document’s title.
The name of the person who created the document.
subject: String
The subject of the document.
keywords: String
Keywords associated with the document. Commas may be used to delineate keywords within the string.
creator: String
If the document was converted to PDF from another format, the name of the conforming product that created the original document from which it was converted.
producer: String
The product that is converting this document to PDF.
creation: Option<DateTime>
The date and time the document was created.
modified: Option<DateTime>
The date and time the document was most recently modified.
lang: String
The natural language of the text in the PDF. If lang
is empty, the root
StructureElementNode::lang will be used (if not empty). Text not in
this language should be marked with StructureElementNode::lang.
raster_dpi: Option<f32>
The DPI (pixels-per-inch) at which features without native PDF support will be rasterized (e.g. draw image with perspective, draw text with perspective, …) A larger DPI would create a PDF that reflects the original intent with better fidelity, but it can make for larger PDF files too, which would use more memory while rendering, and it would be slower to be processed or sent online or to printer.
pdf_a: bool
If true
, include XMP metadata, a document UUID, and s_rgb
output intent
information. This adds length to the document and makes it
non-reproducible, but are necessary features for PDF/A-2b conformance
encoding_quality: Option<i32>
Encoding quality controls the trade-off between size and quality. By default this is set to 101 percent, which corresponds to lossless encoding. If this value is set to a value <= 100, and the image is opaque, it will be encoded (using JPEG) with that quality setting.
structure_element_tree_root: Option<StructureElementNode>
§compression_level: SkPDF_Metadata_CompressionLevel
PDF streams may be compressed to save space. Use this to specify the desired compression vs time tradeoff.
