# 项目说明
图形应用基础框架，基于 pixi.js([官网](https://pixijs.com/), [API Docs](https://pixijs.download/release/docs/index.html))
viewport 使用的 github 开源的 pixi-viewport[pixi-viewport](https://github.com/davidfig/pixi-viewport)
# 路线图
- 图形的位置、旋转属性使用 pixijs 的 transform 变换(完成)
- 图形对象的拖拽使用原始的 transform(图形的变换使用原始的变换)(完成)
- 图形交互抽象(完成)
- 图形子元素变换处理和存储(完成)
- 图形复制功能(完成)
- 绘制应用图形外包围框及旋转缩放功能(完成)
- 绘制增加吸附功能（移动到特定位置附近吸附）（完成）
- 菜单事件及处理
- 打包
- 添加拖拽轨迹限制功能
- 添加图形对象 可编辑属性 定义功能
# pixijs 一些概念
- 如果图形对象本身有碰撞检测区域，子图形的碰撞检测范围在父级的碰撞检测区域内
- v7.2 中 eventMode 属性值的意义：
> - "none"：忽略所有交互事件，且忽略其子级的交互事件。
> - "passive"：不发出(emit)事件，并忽略对自身和非交互式子对象的所有命中测试。交互式子项仍将发出(emit)事件。
> - "auto"：不发出(emit)事件，但如果父级是交互式的，则会进行命中测试。与 v7 中的 interactive=false 相同
> - "static"：发出(emit)事件并进行命中测试。与 v7 中的 interactive=true 相同
> - "dynamic"：发出(emit)事件并进行命中测试，但也会接收模拟的交互事件，以便在鼠标不移动时进行交互

// `Any` contains an arbitrary serialized protocol buffer message along with a
// URL that describes the type of the serialized message.
//
// Protobuf library provides support to pack/unpack Any values in the form
// of utility functions or additional generated methods of the Any type.
//
// Example 1: Pack and unpack a message in C++.
//
// Foo foo = ...;
// Any any;
// any.PackFrom(foo);
// ...
// if (any.UnpackTo(&foo)) {
// ...
// }
//
// Example 2: Pack and unpack a message in Java.
//
// Foo foo = ...;
// Any any = Any.pack(foo);
// ...
// if (any.is(Foo.class)) {
// foo = any.unpack(Foo.class);
// }
// // or ...
// if (any.isSameTypeAs(Foo.getDefaultInstance())) {
// foo = any.unpack(Foo.getDefaultInstance());
// }
//
// Example 3: Pack and unpack a message in Python.
//
// foo = Foo(...)
// any = Any()
// any.Pack(foo)
// ...
// if any.Is(Foo.DESCRIPTOR):
// any.Unpack(foo)
// ...
//
// Example 4: Pack and unpack a message in Go
//
// foo := &pb.Foo{...}
// any, err := anypb.New(foo)
// if err != nil {
// ...
// }
// ...
// foo := &pb.Foo{}
// if err := any.UnmarshalTo(foo); err != nil {
// ...
// }
//
// The pack methods provided by protobuf library will by default use
// 'type.googleapis.com/full.type.name' as the type URL and the unpack
// methods only use the fully qualified type name after the last '/'
// in the type URL, for example "foo.bar.com/x/y.z" will yield type
// name "y.z".
//
// JSON
//
// The JSON representation of an `Any` value uses the regular
// representation of the deserialized, embedded message, with an
// additional field `@type` which contains the type URL. Example:
//
// package google.profile;
// message Person {
// string first_name = 1;
// string last_name = 2;
// }
//
// {
// "@type": "type.googleapis.com/google.profile.Person",
// "firstName": <string>,
// "lastName": <string>
// }
//
// If the embedded message type is well-known and has a custom JSON
// representation, that representation will be embedded adding a field
// `value` which holds the custom JSON in addition to the `@type`
// field. Example (for message [google.protobuf.Duration][]):
//
// {
// "@type": "type.googleapis.com/google.protobuf.Duration",
// "value": "1.212s"
// }
//
message Any {
// A URL/resource name that uniquely identifies the type of the serialized
// protocol buffer message. This string must contain at least
// one "/" character. The last segment of the URL's path must represent
// the fully qualified name of the type (as in
// `path/google.protobuf.Duration`). The name should be in a canonical form
// (e.g., leading "." is not accepted).
//
// In practice, teams usually precompile into the binary all types that they
// expect it to use in the context of Any. However, for URLs which use the
// scheme `http`, `https`, or no scheme, one can optionally set up a type
// server that maps type URLs to message definitions as follows:
//
// * If no scheme is provided, `https` is assumed.
// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
// value in binary format, or produce an error.
// * Applications are allowed to cache lookup results based on the
// URL, or have them precompiled into a binary to avoid any
// lookup. Therefore, binary compatibility needs to be preserved
// on changes to types. (Use versioned type names to manage
// breaking changes.)
//
// Note: this functionality is not currently available in the official
// protobuf release, and it is not used for type URLs beginning with
// type.googleapis.com.
//
// Schemes other than `http`, `https` (or the empty scheme) might be
// used with implementation specific semantics.
//
string type_url = 1;
// Must be a valid serialized protocol buffer of the above specified type.

//
// package google.acl.v1;

// rpc GetAcl(GetAclRequest) returns (Acl) {
// option (google.api.http).get = "/v1/{resource=**}:getAcl";

// Example of a mixin configuration:
//
// apis:
// - name: google.storage.v2.Storage
// mixins:
// - name: google.acl.v1.AccessControl
//
// The mixin construct implies that all methods in `AccessControl` are
// also declared with same name and request/response types in
// `Storage`. A documentation generator or annotation processor will
// see the effective `Storage.GetAcl` method after inheriting
// documentation and annotations as follows:
//
// service Storage {
// // Get the underlying ACL object.
// rpc GetAcl(GetAclRequest) returns (Acl) {
// option (google.api.http).get = "/v2/{resource=**}:getAcl";
// }

// }
//
// Note how the version in the path pattern changed from `v1` to `v2`.
//
// If the `root` field in the mixin is specified, it should be a

//
// apis:
// - name: google.storage.v2.Storage
// mixins:
// - name: google.acl.v1.AccessControl
// root: acls
//
// This implies the following inherited HTTP annotation:

// // Get the underlying ACL object.
// rpc GetAcl(GetAclRequest) returns (Acl) {
// option (google.api.http).get = "/v2/acls/{resource=**}:getAcl";

// insertions to the same point will come out in the order they were added).
// The double-@ is intended to make it unlikely that the generated code
// could contain things that look like insertion points by accident.

// other declarations that should be placed in this scope.
//
// Note that if the line containing the insertion point begins with
// whitespace, the same whitespace will be added to every line of the
// inserted text. This is useful for languages like Python, where
// indentation matters. In these languages, the insertion point comment
// should be indented the same amount as any inserted code will need to be
// in order to work correctly in that context.

//
// Notes:
// - A location may refer to a repeated field itself (i.e. not to any
// particular index within it). This is used whenever a set of elements are
// logically enclosed in a single code segment. For example, an entire
// extend block (possibly containing multiple extension definitions) will
// have an outer location whose path refers to the "extensions" repeated

// - Multiple locations may have the same path. This happens when a single
// logical declaration is spread out across multiple places. The most
// obvious example is the "extend" block again -- there may be multiple
// extend blocks in the same scope, each of which will have the same path.
// - A location's span is not always a subset of its parent's span. For
// example, the "extendee" of an extension declaration appears at the
// beginning of the "extend" block and is shared by all extensions within
// the block.
// - Just because a location's span is a subset of some other location's span
// does not mean that it is a descendant. For example, a "group" defines
// both a type and a field in a single declaration. Thus, the locations
// corresponding to the type and field and their components will overlap.

// `FieldMask` represents a set of symbolic field paths, for example:
//
// paths: "f.a"
// paths: "f.b.d"
//
// Here `f` represents a field in some root message, `a` and `b`
// fields in the message found in `f`, and `d` a field found in the
// message in `f.b`.
//
// Field masks are used to specify a subset of fields that should be
// returned by a get operation or modified by an update operation.
// Field masks also have a custom JSON encoding (see below).
//
// # Field Masks in Projections
//
// When used in the context of a projection, a response message or
// sub-message is filtered by the API to only contain those fields as
// specified in the mask. For example, if the mask in the previous
// example is applied to a response message as follows:
//
// f {
// a : 22
// b {
// d : 1
// x : 2
// }
// y : 13
// }
// z: 8
//
// The result will not contain specific values for fields x,y and z
// (their value will be set to the default, and omitted in proto text
// output):
//
//
// f {
// a : 22
// b {
// d : 1
// }
// }
//
// A repeated field is not allowed except at the last position of a
// paths string.
//
// If a FieldMask object is not present in a get operation, the
// operation applies to all fields (as if a FieldMask of all fields
// had been specified).
//
// Note that a field mask does not necessarily apply to the
// top-level response message. In case of a REST get operation, the
// field mask applies directly to the response, but in case of a REST
// list operation, the mask instead applies to each individual message
// in the returned resource list. In case of a REST custom method,
// other definitions may be used. Where the mask applies will be
// clearly documented together with its declaration in the API. In
// any case, the effect on the returned resource/resources is required
// behavior for APIs.
//
// # Field Masks in Update Operations
//
// A field mask in update operations specifies which fields of the
// targeted resource are going to be updated. The API is required
// to only change the values of the fields as specified in the mask
// and leave the others untouched. If a resource is passed in to
// describe the updated values, the API ignores the values of all
// fields not covered by the mask.
//
// If a repeated field is specified for an update operation, new values will
// be appended to the existing repeated field in the target resource. Note that
// a repeated field is only allowed in the last position of a `paths` string.
//
// If a sub-message is specified in the last position of the field mask for an
// update operation, then new value will be merged into the existing sub-message
// in the target resource.
//
// For example, given the target message:
//
// f {
// b {
// d: 1
// x: 2
// }
// c: [1]
// }
//
// And an update message:
//
// f {
// b {
// d: 10
// }
// c: [2]
// }
//
// then if the field mask is:
//
// paths: ["f.b", "f.c"]
//
// then the result will be:
//
// f {
// b {
// d: 10
// x: 2
// }
// c: [1, 2]
// }
//
// An implementation may provide options to override this default behavior for
// repeated and message fields.
//
// In order to reset a field's value to the default, the field must
// be in the mask and set to the default value in the provided resource.
// Hence, in order to reset all fields of a resource, provide a default
// instance of the resource and set all fields in the mask, or do
// not provide a mask as described below.
//
// If a field mask is not present on update, the operation applies to
// all fields (as if a field mask of all fields has been specified).
// Note that in the presence of schema evolution, this may mean that
// fields the client does not know and has therefore not filled into
// the request will be reset to their default. If this is unwanted
// behavior, a specific service may require a client to always specify
// a field mask, producing an error if not.
//
// As with get operations, the location of the resource which
// describes the updated values in the request message depends on the
// operation kind. In any case, the effect of the field mask is
// required to be honored by the API.
//
// ## Considerations for HTTP REST
//
// The HTTP kind of an update operation which uses a field mask must
// be set to PATCH instead of PUT in order to satisfy HTTP semantics
// (PUT must only be used for full updates).
//
// # JSON Encoding of Field Masks
//
// In JSON, a field mask is encoded as a single string where paths are
// separated by a comma. Fields name in each path are converted
// to/from lower-camel naming conventions.
//
// As an example, consider the following message declarations:
//
// message Profile {
// User user = 1;
// Photo photo = 2;
// }
// message User {
// string display_name = 1;
// string address = 2;
// }
//
// In proto a field mask for `Profile` may look as such:
//
// mask {
// paths: "user.display_name"
// paths: "photo"
// }
//
// In JSON, the same mask is represented as below:
//
// {
// mask: "user.displayName,photo"
// }
//
// # Field Masks and Oneof Fields
//
// Field masks treat fields in oneofs just as regular fields. Consider the
// following message:
//
// message SampleMessage {
// oneof test_oneof {
// string name = 4;
// SubMessage sub_message = 9;
// }
// }
//
// The field mask can be:
//
// mask {
// paths: "name"
// }
//
// Or:
//
// mask {
// paths: "sub_message"
// }
//
// Note that oneof type names ("test_oneof" in this case) cannot be used in
// paths.
//
// ## Field Mask Verification
//
// The implementation of any API method which has a FieldMask type field in the
// request should verify the included field paths, and return an
// `INVALID_ARGUMENT` error if any path is unmappable.
message FieldMask {
// The set of field mask paths.
repeated string paths = 1;

//
// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
// second table is needed for interpretation, using a [24-hour linear
// smear](https://developers.google.com/time/smear).
//
// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
// restricting to that range, we ensure that we can convert to and from [RFC
// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
//
// # Examples
//
// Example 1: Compute Timestamp from POSIX `time()`.
//
// Timestamp timestamp;
// timestamp.set_seconds(time(NULL));
// timestamp.set_nanos(0);
//
// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
//
// struct timeval tv;
// gettimeofday(&tv, NULL);
//
// Timestamp timestamp;
// timestamp.set_seconds(tv.tv_sec);
// timestamp.set_nanos(tv.tv_usec * 1000);
//
// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
//
// FILETIME ft;
// GetSystemTimeAsFileTime(&ft);
// UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
//
// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
// Timestamp timestamp;
// timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
//
// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
//
// long millis = System.currentTimeMillis();
//
// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
// .setNanos((int) ((millis % 1000) * 1000000)).build();
//
// Example 5: Compute Timestamp from Java `Instant.now()`.
//
// Instant now = Instant.now();
//
// Timestamp timestamp =
// Timestamp.newBuilder().setSeconds(now.getEpochSecond())
// .setNanos(now.getNano()).build();
//
// Example 6: Compute Timestamp from current time in Python.
//
// timestamp = Timestamp()
// timestamp.GetCurrentTime()
//
// # JSON Mapping
//
// In JSON format, the Timestamp type is encoded as a string in the
// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
// where {year} is always expressed using four digits while {month}, {day},
// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
// is required. A proto3 JSON serializer should always use UTC (as indicated by
// "Z") when printing the Timestamp type and a proto3 JSON parser should be
// able to accept both UTC and other timezones (as indicated by an offset).
//
// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
// 01:30 UTC on January 15, 2017.
//
// In JavaScript, one can convert a Date object to this format using the
// standard
// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
// method. In Python, a standard `datetime.datetime` object can be converted
// to this format using
// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
// the Joda Time's [`ISODateTimeFormat.dateTime()`](
// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
// ) to obtain a formatter capable of generating timestamps in this format.

Protocol Buffers - Google's data interchange format
Copyright 2008 Google Inc.
https://developers.google.com/protocol-buffers/
This package contains a precompiled binary version of the protocol buffer
compiler (protoc). This binary is intended for users who want to use Protocol
Buffers in languages other than C++ but do not want to compile protoc
themselves. To install, simply place this binary somewhere in your PATH.
If you intend to use the included well known types then don't forget to
copy the contents of the 'include' directory somewhere as well, for example
into '/usr/local/include/'.
Please refer to our official github site for more installation instructions:
