| SkString SkPDF::Metadata::fAuthor |
The name of the person who created the document.
| enum SkPDF::Metadata::CompressionLevel SkPDF::Metadata::fCompressionLevel = CompressionLevel::Default |
| DateTime SkPDF::Metadata::fCreation = {0, 0, 0, 0, 0, 0, 0, 0} |
The date and time the document was created.
The zero default value represents an unknown/unset time.
| SkString SkPDF::Metadata::fCreator |
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.
| int SkPDF::Metadata::fEncodingQuality = 101 |
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.
| SkExecutor* SkPDF::Metadata::fExecutor = nullptr |
Executor to handle threaded work within PDF Backend.
If this is nullptr, then all work will be done serially on the main thread. To have worker threads assist with various tasks, set this to a valid SkExecutor instance. Currently used for executing Deflate algorithm in parallel.
If set, the PDF output will be non-reproducible in the order and internal numbering of objects, but should render the same.
Experimental.
| SkString SkPDF::Metadata::fKeywords |
Keywords associated with the document.
Commas may be used to delineate keywords within the string.
| DateTime SkPDF::Metadata::fModified = {0, 0, 0, 0, 0, 0, 0, 0} |
The date and time the document was most recently modified.
The zero default value represents an unknown/unset time.
| enum SkPDF::Metadata::Outline SkPDF::Metadata::fOutline = Outline::None |
| bool SkPDF::Metadata::fPDFA = false |
If true, include XMP metadata, a document UUID, and sRGB output intent information.
This adds length to the document and makes it non-reproducable, but are necessary features for PDF/A-2b conformance
| SkString SkPDF::Metadata::fProducer = SkString("Skia/PDF m" SKPDF_STRING(SK_MILESTONE)) |
The product that is converting this document to PDF.
| SkScalar SkPDF::Metadata::fRasterDPI = SK_ScalarDefaultRasterDPI |
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.
| StructureElementNode* SkPDF::Metadata::fStructureElementTreeRoot = nullptr |
An optional tree of structured document tags that provide a semantic representation of the content.
The caller should retain ownership.
| SkString SkPDF::Metadata::fSubject |
The subject of the document.
| enum SkPDF::Metadata::Subsetter SkPDF::Metadata::fSubsetter = kHarfbuzz_Subsetter |
| SkString SkPDF::Metadata::fTitle |
The document's title.
