.ai save: objects next to type keep their own transparency
The reader gives an Xy right after a compound path or a text object to that object. The writer now writes XR before the Xy of type, images and guides, so type next to type, a compound path before type, image or guide, and type before an image or guide keep their own opacity, blend mode and knockout shape flag. - Type keeps its Isolate Blending and Knockout Group state in a state block after its text object, as its outlines did on their group. - The reader no longer gives a layer the Xy before its last text object. - The ASCII85 end marker of the text document stays on one line. - The warning and docs/file-format-parity.md also list area type in an open frame, type on an open path whose ends meet, type of only white space and threads of type on a path as written as outlines. - README.md, ROADMAP.md, docs/gaps.md, docs/roadmap.md and docs/target-app-parity.md describe the editing copy a saved .ai holds. - clip_path's doc comment is back on clip_path. - import_fuzz reaches threaded area type and vertical type.

At a precision of 9 decimals or fewer, SVG export writes each number from an integer when the integer rounds it as the decimal formatter does; the formatter still writes values halfway between two written numbers and values too large for the integer. Exporting one path of 200,000 anchors takes a median of 43.4 ms instead of 167.0 ms on Windows 11, and 20,000 rectangles 81.4 ms instead of 141.4 ms, with the same SVG (`crates/svg/src/lib.rs`).
|
||||
SVG import reads each `<circle>` and `<ellipse>` as the ellipse VectorCraft draws: four smooth anchors on the axes, starting at the right, with handles of the standard length, so an ellipse exported as `<ellipse>` comes back with the anchors it was written from and draws the same (`circles_and_ellipses_import_as_the_ellipse_drawn` in `crates/svg/tests/it/basic_shapes.rs`, `filled_ellipse_on_the_artboard_edge_survives_visually` in `prop_svg.rs`).
|
||||
SVG import keeps attributes in other applications' XML namespaces (`plotter:pen="2"`) on the objects and layers they belong to, as it keeps their `data-*` attributes: copies, duplicates and `.vectorcraft` files keep them, and SVG export writes them back with each namespace declared once on the root (the rest of #522; `crates/svg/tests/it/foreign_attributes.rs`, `tests/attributes.rs`).

In a `.ai` or EPS opened from its editing data, type has its text object's opacity and blend mode, whether it is made from the file's text document or taken from the page. Where such type has transparency and comes in with other art (the rest of its look, or page type and strokes that go with it), a group of them has it. Where the page draws its type, or the strokes around it, with transparency that is neither its text object's nor its text object's combined with that of the objects around it, the page's type and strokes keep their own instead (`crates/eps/src/import/tests_native.rs`). Where the page draws type of no text object over text objects made from the text document, with their words in any case, that type is theirs as the page draws it and is left out; the page's other type of no text object goes only to text objects whose type the text document can't make, or else is left out with a warning.

A PDF-compatible `.ai` saved with Include Editing Data for Other Apps writes point type, area type and type on a path as type in its editing copy, and objects next to it keep their own transparency (`crates/eps/src/ai_editing/tests.rs`, `cmd::fileio::tests_pdfedit::type_comes_back_from_the_editing_copy`; [file-format-parity.md](file-format-parity.md) lists what is written as outlines).

In a `.ai` or EPS opened from its editing data, type has its text object's opacity, blend mode and knockout shape flag, whether it is made from the file's text document or taken from the page, and type made from the text document takes its text object's lock.

|

A `.ai` or EPS graphic style library, whose editing data holds the styles and their list but no layers, opens with those styles in list order. Other Library… loads another document's graphic styles ([Apply graphic styles](https://helpx.adobe.com/illustrator/desktop/special-effects-styles/apply-graphic-styles/apply-graphic-styles.html)) and lists such a library's styles in a library panel. A `.ai` or EPS read as its PDF part or page because its layers can't be used also gets the styles of its list in place of the default ones (`crates/eps/src/import/tests_native.rs`, `cmd::fileio::tests_aiimport::a_graphic_style_library_in_a_ai_file_without_layers_loads_its_styles`).

A `.ai` or EPS opened from its editing data whose text document makes the type of every text object that shows takes all its type from the text document: each text object stays in its own group, frame and layer, the page's type isn't matched with them, a file of more than 5,000 text objects still opens with its layers, and type the page draws differently (in another font) keeps the layers, with a warning. A line break inside a paragraph stays a line break in it (`crates/eps/src/import/tests_native.rs`, `crates/eps/src/import/ate.rs`).
