Export
The export options.

Properties
If true, the export will include text bounding boxes that account for glyph overhangs. When enabled, text blocks with glyphs that extend beyond their frame (e.g., decorative fonts with swashes) will be exported with the full glyph bounds visible, preventing text clipping. The default value is false.
Length of one crop mark line, in design units. It shares the unit of printMarkOffset, because the exported sheet grows by the sum of the two. Values <= 0 fall back to the equivalent of 15 pt. Only used when exportPdfWithCropMarks is true.
Draw crop marks outside the bleed on every exported PDF page. Crop marks are the four pairs of corner lines that show a print shop where to cut. They are painted in the PDF registration colorant All, so they appear on every separation. This grows the PDF MediaBox to the trim plus printMarkOffset + cropMarkLength on each side, because the marks live outside the bleed. The page content, the TrimBox and the BleedBox keep describing the same physical rectangles. A page whose trim is not a rectangle, so a page with page/marginScale above 1, gets no marks and no larger page. The default value is false.
Export the PDF document with a higher compatibility to different PDF viewers. Bitmap images and some effects like gradients will be rasterized with the DPI setting instead of embedding them directly. The default value is true.
Draw registration marks outside the bleed on every exported PDF page. A registration mark is the bullseye target a press operator aligns the plates by. One sits at the middle of each page edge, and each is painted in the PDF registration colorant All, so they appear on every separation. This grows the PDF MediaBox on the same terms as exportPdfWithCropMarks, and a page whose trim is not a rectangle gets no marks either. A registration mark has one fixed size, so there is no knob for it. The default value is false.
Export the PDF document with an underlayer. An underlayer is generated by adding a graphics block behind the existing elements of the shape of the elements on the page.
The JPEG quality to use when encoding to JPEG. Valid values are (0-1], higher means better quality. Ignored for other encodings. The default value is 0.9.
The encoding quality to use for images that have to be rasterized during PDF export, e.g. images with effects or blurs applied, or any bitmap image when exportPdfWithHighCompatibility is enabled. Valid values are (0-1]. Exactly 1.0 (the default) keeps the lossless encoding, like webpQuality. Any value below 1.0 re-encodes rasterized images as lossy JPEG at the given quality, which produces much smaller files. Only rasterized content that is fully opaque can be re-encoded, because JPEG has no alpha channel. Content that keeps transparency, for example when exporting a block or a page without a background fill, stays losslessly encoded whatever this option is set to. Images whose original JPEG data is embedded directly are never re-encoded and are not affected by this option. The default value is 1.0.
The PNG compression level to use, when exporting to PNG. Valid values are 0 to 9, higher means smaller, but slower. Quality is not affected. Ignored for other encodings. The default value is 5.
Distance from the trim to the nearest edge of any printer's mark, in design units. Every mark type shares it, so it is comparable with the page bleed without converting. A negative value falls back to the equivalent of 6 pt. Zero is a real offset that places a mark on the trim edge. A mark may reach into the bleed, which the knife removes anyway, and every mark carries a white knockout underneath so it stays legible over artwork. Only used when exportPdfWithCropMarks or exportPdfWithRegistrationMarks is true.
Stroke width of any printer's mark, in points. Every mark type shares it, and a print shop calls it the weight. Points, not design units, because a weight is a print measure that never meets the page geometry. Must be 0. Values <= 0 fall back to 0.25, a hairline. Only used when exportPdfWithCropMarks or exportPdfWithRegistrationMarks is true.
An optional target height used in conjunction with target width. If used, the block will be rendered large enough, that it fills the target size entirely while maintaining its aspect ratio.
An optional target width used in conjunction with target height. If used, the block will be rendered large enough, that it fills the target size entirely while maintaining its aspect ratio.
Maximum acceptable curve-fit error, in pixels, when vectorising the underlayer contour. Smaller values produce tighter fits at the cost of more path complexity. Useful together with underlayerRenderRatio for small text on large pages. Must be 0. Values <= 0 fall back to 2.0. Defaults to 2.0 for backward compatibility.
The adjustment in size of the shape of the underlayer.
Resolution multiplier for the raster pass that extracts the underlayer contour. Higher values produce sharper underlayer outlines at the cost of memory and export time. Useful for small text on large pages, where the 1.0 default can miss fine glyph details. Must be 0. Values <= 0 fall back to 1.0. Defaults to 1.0 for backward compatibility.
The name of the spot color to be used for the underlayer's fill.
The WebP quality to use when encoding to WebP. Valid values are (0-1], higher means better quality. WebP uses a special lossless encoding that usually produces smaller file sizes than PNG. Ignored for other encodings. Defaults to 1.0.
