The ColorStop offset < 0 and > 1 should be treated as 0 and 1 respectively.
The offset value < than the previous offset value should be replaced
by the previous value - without this change segfault occurred.
Validating the APIs parameters values is the user responsibility.
When copying an attribute, url information of stype's composite is overwritten with memcpy.
This causes double free by deleting the wrong string in freeNodeStyle.
This patch introduces tvg loader module for loading .tvg binary files.
This allows to load and reuse pregenerated scene.
tvg file format:
.tvg is a binary file format designed for saving/restoring the scene content.
It allows to save scenes and reuse them in other apps or to restore state of
the application.
@Example:
auto picture = tvg::Picture::gen();
picture->load(EXAMPLE_DIR"/tvg_file.tvg");
canvas->push(move(picture));
@API Additions:
Result paint(std::unique_ptr<Paint> paint) noexcept;
@Issue: Issue ticket is #375.
The loader was ready to handle the gradient stroke, but there was no API to support
it when the loader was introduced. We've had this API for a while already, so
its call has been added.
We are doing enough calculations in the parser if the unit is user space.
This causes the cx,cy coordinates of radial gradient to be calculated incorrectly.
So remove it.
Calculation of objectBoundingBox case in linear gradient is incorrect code.
This causes the x,y coordinates of the linear gradient to be calculated incorrectly.
So remove it.
The 'loader->svgParse->global' variable was uninitialized when no viewBox attribute
was set. If gradient was applied, the division by zero occured and no gradient was drawn.
For now the bounding box of all the shapes was established and if it was larger
than the viewBox of the SVG, the clipping layer was added. The bounds api
returns the rectangle that encloses the shapes before any transformations.
So comparing it with the viewBox doesn't make sense. The comparison is removed
and the clipping layer is always added.
- Change tag name "Doc" to "Svg"
- Fix "Mask" tag name.
- Add element to skip output
- title
- Add attribute to skip output
- id, data-name, version, overflow=visible, xmlns*, xml:space
1.
Modify that attribute information used for use type
looks like it was used for g type.
2.
Fix clippath node looking like setting "none"
(clippath's display = false is intentional)
strtof's behavior is changed by system locale.
https://linux.die.net/man/3/strtof
Because of this, strtof(10.0000) returns 0.0 in some locales.
When a given value string is locale-independent, strtof has to be
replaced to custom function.
If no viewBox attribute is given, the height and width attributes are used
to establish the viewBox size. However, this information was not available
inside the scene builder, even though it was needed.
not only clippath but alpha compositions might also have any valid color.
Set it default and let it override values while appending shapes if it's necessary.
Current loader could return invalid shapes -default, from _appendShape()-
by a certain interpretation result,
Though it's a wrong or exception case, we can prevent worse case by avoiding it.
