An action or journal entry recorded before Scale and Reflect followed the
turned bounding box has no basis value. Replayed, such a step now acts along
the page's axes, as it did when it was recorded; steps recorded now carry
basis "box" and replay along the box. The built-in Reflect Horizontal action
names basis "box", so it keeps reflecting across the box's own axis.
The symbol test that reflects a turned instance names basis "page", which
is the reflection it was written for.
A block's line took the tallest ascent and deepest descent of its
characters, or the height of the stack's em boxes, whichever was larger.
The top block line's characters reach above the stack by their ascent
past the em box, and the bottom line's below it by their descent, so with
a wide Line Gap the line was too short for them. The line's ascent and
descent now also take in each character's reach from its own block line's
baseline.
A WMF without a placeable box picks its scale from the map mode its
drawing records are played in. Lines and shapes drawn under R2_NOP or
R2_XORPEN, and PATBLT records the reader does not fill, no longer count,
with the mix mode saved and restored with SAVEDC and RESTOREDC.
An open stroke that reaches far outside the picture is left out before
it joins the strokes waiting to be joined, so the strokes drawn before
it are still added.
A fill in a glyph's clip marked the clip as filled before the fill was
added. When the fill painted nothing (a palette index past the palette,
or a radial gradient that draws no circle), the next glyph painted in
the same clip became the clip's only child, and closing the clip kept
that glyph on its own, so it drew outside the clip.
The clip is now marked filled only when the fill adds the clip's first
child, and a fill that adds nothing leaves the mark as it was.
A clip group with a fill or stroke of its own and no geometry effect is
baked through bake_pieces, which baked the clipping path like any other
member instead of applying the geometry effects in it as the canvas clips
by it. A compound clipping path whose member has a Transform effect with
copies then baked into nested compound paths, and SVG, PDF and the other
exports dropped the moved member and its copies from the clip.
bake_pieces now applies with_clip_effects_applied to the clipping path
first, as the plain clip group route already does. Clipping type keeps
its own handling.
A plot of the art's bounds now leaves placed images, objects at 0%
opacity and unpainted paths out of the art of a dynamic symbol, as it
does for other symbols. An object that an instance's fill, stroke or
opacity makes the plot draw is measured for that instance only, and an
instance whose symbol holds nothing else is left out, so a document
with only such instances is refused.
A PDF/A-2b export at PDF 1.4 with Create PDF Layers and a page longer
than 14,400 pt is written as PDF 1.6, which has PDF layers. The export
decided which layers place their instances' symbol art before it raised
the version, so a hidden layer, written as a PDF layer that is off, kept
its instances' art without the art's live effects.
The version a long page needs is now settled before the document is
baked. The pages come from the artboards, which baking leaves as they
are.
The check before a PNG or JPEG is embedded as it is read the profile's
color space only from a profile of at least 128 bytes, so a gray or RGB
profile cut short after its color space reached the PDF writer. The
color space is now read from bytes 16..20 of any profile that holds
them, and valid_icc rejects the short profile.
When the last of the bounded breaks such a line reads came right before
U+2028, the line ended at that break and the next line held only the
forced break, drawing an empty line. The line now reads on to the
forced break and ends there when it fits as drawn.
In PDF/X-1a, a tagged gray JPEG that the Compression settings keep as
JPEG was decoded and written with Flate. It is now written with its
JPEG data unchanged, in DeviceGray without its profile.
A PNG or JPEG embedded as it is now has its gray or RGB profile checked
with valid_icc, like the images the recoder writes: a malformed profile
is left out, the JPEG keeping its JPEG data and the PNG decoded.
After the merge of main, the tracked-ligatures note is the only reader of
the first run's features, and the branch replaces that check with one that
reads every frame of the story, so clippy reported the binding as unused.
