Kirill Osipov 9a606ec4e9 Cap PixelBuffer.from_bytes dimensions at 64k x 64k 
Following review feedback, the reader now rejects a header claiming a
width or height beyond 65536, guarding against malformed byte streams
that would otherwise trigger an unreasonable allocation. The writer
stays full 32-bit ('unlimited'), and native little-endian order and the
transparency mask are kept as-is. Adds Ruby and Python tests for the
oversized-header rejection.

Kirill Osipov 35ec1107b6 Add PixelBuffer#to_bytes for zero-overhead RGBA pixel access 
Exposes a GSI method on tl::PixelBuffer that returns the raw ARGB32
contents as a byte vector (4 bytes per pixel, row-major, top to bottom)
via a single memcpy. Unlike to_png_data this skips all image encoding,
which is useful when the caller just wants direct pixel data.

Matthias Koefferlein 7508c8e4a4 Enabling context writing also for top cells - this allows the OASIS writer to generate proxy cells on output during fix of issue #2350 2026-05-25 01:13:58 +02:00
Matthias Koefferlein 37977d21e9 Fixing issue #2350 (strm2oas writes empty OAS) 
Problem was that the OASIS writer was simply ignoring
all top level proxy cells (PCells, Library references).

The original bug #1835 fixed that by changing the
reader behavior, so it would keep top level proxies.
However, doing the spin through the writer got them
removed and in addition, the cleanup happing during
editing would also remove them.

Solution is to centralize the strategy of cleaning
cells. The cleanup now is changed to not remove
proxy top cells if they are the only ones. This is
consistent with the previous reader-only behavior.

The writer implements the same behavior by means
dropping cells marked for cleanup, instead of simply
skipping all proxy cells.

Matthias Koefferlein 95271e3edc Fixing color interpolation of false color maps 
Problem was when an interval was separated from
the rest through a discontinuous color and did not have any
color range (start and end color same).

The new scheme fixes the problem by computing a
data mapping that has two slightly distinct values
for the two discontinuous colors.

Matthias Koefferlein 378d2cd961 Changed visibility management of tool options (aka "Editor options") 
Now, the tool options dock is either visible or not. Visibility
can be configured like for the other docks. Key binding stays
"F3" by default for the dock visibility.

The dock is populated with pages depending on the tool. It may
also be empty.

Matthias Koefferlein 4cc1d2ff9a Fixed a potential crash 
This bug was triggered during development and happened
because the tool bar build code was invalidating
QAction objects indirectly while they are used for
building the main menu.

Solution is to separate building of menu bar and
tool bar / context menus.

Matthias Koefferlein b5be4fc497 Small bugfix on object snap - observe snap directions 
Problem: snapping with angle constraints and object snapping
sometimes gave results not conforming to the angle constaints.
This happened when shape edges are parallel to the cutlines that
define the angle constraint.
