Description
The application is a divisional application, the application number of the original application is 201610911029.4, the application date is 10 months and 18 days in 2016, and the name of the application is a rendering method and device.
Technical Field
The present invention relates to the field of computer technologies, and in particular, to a rendering method and apparatus.
Background
In the writing software of the android system, two common rendering modes are surface view rendering and OpenGL rendering. The SurfaceView rendering is well supported by an API (Application Programming Interface ), and the handwriting can achieve a good smooth effect, so that the SurfaceView rendering is commonly used for following and drawing the handwriting and inserting pictures into a canvas, but when continuous handwriting or picture moving and scaling are performed in the canvas of the writing software, the SurfaceView rendering speed cannot keep up with the operation speed, so that the phenomenon of blocking is caused, and the user experience is affected. Particularly, when global movement and scaling are performed, each handwriting or picture needs to be traversed, drawing updating is performed one by one on the view of the surface view, the whole rendering speed is reduced along with the increase of the number of the handwriting or picture, and the picture is blocked more and more.
The OpenGL rendering speed is very fast, and the OpenGL rendering method is widely applied to games and applications with gorgeous animation effects. When OpenGL rendering is used, the rendering speed of moving, scaling the handwriting or picture is increased by at least 10 times (as the number of handwriting and picture increases, the effect is more obvious, and even the rendering speed OpenGL can be reached to be in the millisecond level, while the surfview rendering is in the second level). In particular, for OpenGL rendering of a picture, texture data of the picture is stored in a video memory, and time consumption is hardly required when OpenGL rendering is performed. The OpenGL rendering does not have a click feel at all. However, openGL has its limitation that OpenGL has no smooth effect on lines, and drawing shape is not acceptable when lines are thick.
Therefore, in the prior art, a single rendering mode is adopted, so that the beneficial effects of different rendering modes cannot be achieved at the same time, and the defect limitation of the single rendering mode cannot be overcome. It is also not possible to use two rendering modes on one view, subject to API support by the operating system.
Disclosure of Invention
The invention aims to provide a rendering method and a rendering device, which can use two rendering modes, have the beneficial effects of different rendering modes and overcome the defect limitation of a single rendering mode.
In order to achieve the above object, an aspect of the present invention provides a rendering method, including:
configuring a first view and a second view on a canvas of the writing software; wherein the first view and the second view both cover the canvas, and the backgrounds of the first view and the second view are transparent;

if the first rendering mode is selected to be used, drawing a specified object on the first view by using the first rendering mode;
and if the second rendering mode is selected to be used, drawing the specified object on the second view by using the second rendering mode.
The implementation of the invention has the following beneficial effects:
the invention configures the first view and the second view on the canvas of the writing software, and because the view background is transparent, the two views are overlapped, and a user can simultaneously see the contents rendered by the two views. And according to the requirements, one part of the objects to be drawn is drawn by using a first rendering mode, and the other part of the objects to be drawn is drawn by using a second rendering mode, so that the objects to be drawn with high requirements on the smooth effect and the objects to be drawn with high requirements on the rendering speed can achieve ideal rendering effects, and the defect limitation of a single rendering mode is overcome.
In one embodiment, the selecting a rendering mode according to the object to be drawn includes:
determining the attribute of an object to be drawn according to the current working mode of writing software; when the writing software is in a writing mode, the object to be drawn is an object generated by writing according to touch operation of a user; in the case that the writing software is in a moving mode or a zooming mode, the object to be drawn is an object which moves or zooms according to the touch operation of a user;
if the object to be drawn is an object generated by writing according to touch operation of a user, selecting to use a first rendering mode;
and if the object to be drawn is the object which is moved or zoomed according to the touch operation of the user, selecting to use the second rendering mode.
Further, if the first rendering mode is selected, drawing the specified object on the first view by using the first rendering mode, which specifically includes:
if the first rendering mode is selected to be used, recording second object data, and emptying the second view; the second object data are data corresponding to all objects in the second view at present;
drawing an object corresponding to the second object data on the first view by using a first rendering mode;
monitoring touch operation of a user, and drawing an object generated according to the touch operation writing in a first rendering mode on the first view;
if the second rendering mode is selected, drawing the specified object on the second view by using the second rendering mode, wherein the method specifically comprises the following steps:

drawing an object corresponding to the first object data in the second view by using a second rendering mode;
and monitoring touch operation of a user, and drawing an object which is moved or zoomed according to the touch operation in the second view by using a second rendering mode.
Further, the first rendering mode is surface view rendering, and the second rendering mode is OpenGL rendering.
Further, the object comprises a picture and handwriting; and when the appointed object is drawn on the second view by using a second rendering mode, if the object is handwriting, drawing the handwriting according to a preset line width by using the second rendering mode.

When the working mode is switched, all objects are switched to the other view, so that the problem of image overlapping errors can be avoided.
In the further scheme, when the OpenGL is used for rendering and drawing the handwriting, the OpenGL is poor in rendering effect on the thick line, and the smooth effect can be achieved by adopting the fixed line width for drawing the handwriting.

if the object to be drawn is a zoom control point, selecting a first rendering mode; the scaling control point is defined as a control point which is generated on the edge of the picture according to clicking operation of a user and used for controlling the size of the picture;
and if the object to be drawn is a picture, selecting a second rendering mode.
In another embodiment, the rendering mode is determined directly according to the type of the drawing object. When the drawing object is a picture, as the speed requirement of picture insertion, scaling or movement is faster, a rendering mode with fast rendering speed can be used, and the scaling control point generated on the edge of the picture is relatively lower in following hand requirement, so that rendering in a rendering mode with normal speed but good other effects is adopted to meet the requirement. Different rendering modes are used according to actual demands, so that the running speed and the effect balance of the writing software are facilitated.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flowchart of a first embodiment of a rendering method provided by the present invention is shown. In a first embodiment, a rendering method includes:
s1, configuring a first view and a second view on a canvas of writing software; wherein the first view and the second view both cover the canvas, and the backgrounds of the first view and the second view are transparent;
s2, selecting a rendering mode according to the object to be drawn;
s3, if the first rendering mode is selected to be used, drawing a specified object on the first view by using the first rendering mode;
and S4, if the second rendering mode is selected to be used, drawing the specified object on the second view by using the second rendering mode.
According to the first embodiment of the rendering method, the first view and the second view are configured on the canvas of the writing software, and the two views are overlapped due to transparent view background, so that a user can see the content rendered by the two views at the same time. And according to the requirements, one part of the objects to be drawn is drawn by using a first rendering mode, and the other part of the objects to be drawn is drawn by using a second rendering mode, so that the objects to be drawn with high requirements on the smooth effect and the objects to be drawn with high requirements on the rendering speed can achieve ideal rendering effects, and the defect limitation of a single rendering mode is overcome.
Referring to fig. 2, a specific flowchart of step S2 in an embodiment of the rendering method provided by the present invention is shown. Step S2 in the first embodiment specifically includes:
s211, determining the attribute of an object to be drawn according to the current working mode of writing software; when the writing software is in a writing mode, the object to be drawn is an object generated by writing according to touch operation of a user; in the case that the writing software is in a moving mode or a zooming mode, the object to be drawn is an object which moves or zooms according to the touch operation of a user;
s212, if the object to be drawn is an object generated by writing according to touch operation of a user, selecting to use a first rendering mode;
s213, if the object to be drawn is the object which is moved or zoomed according to the touch operation of the user, selecting to use the second rendering mode.
It should be noted that, the working modes of the writing software of the touch screen terminal include a writing mode, a moving mode and a zooming mode, and those skilled in the art can know that in the writing mode, a user performs a touch operation on the touch screen terminal, and according to the track of the touch operation, a handwriting object can be generated, and the user can insert a picture on the touch screen terminal; in a moving mode, a user executes touch operation on the touch screen terminal, and an object corresponding to a touch point can be moved according to a track of the touch operation; in a zoom mode, a user performs touch operation on the edge of an object on the touch screen terminal, and the object can be zoomed according to the track of the touch operation; further, the movement mode and the scaling mode may be set to the same mode.
The writing software may be triggered into different modes of operation in a number of ways. For example, writing software on a touch screen terminal enters a writing mode by default when the writing software is started, a specific gesture can be adopted to enter a moving and zooming mode, the specific gesture can be triggered by three points, namely, three fingers of a user are simultaneously pressed down, the moving and zooming mode is entered, at the moment, an object to be drawn is switched to an object which moves or zooms according to the touch operation of the user, namely, the object is updated according to the moving and zooming operation; when the user finishes moving and zooming, the user can enter a writing mode when lifting the hand. In addition, a mode selection field may be provided on a toolbar of the writing software, and the user may switch the operation mode by operating the mode selection field.
The step S3 specifically comprises the following steps:
s311, if the first rendering mode is selected to be used, recording second object data, and emptying the second view; the second object data are data corresponding to all objects in the second view at present;
s312, drawing an object corresponding to the second object data on the first view by using a first rendering mode;
s313, monitoring touch operation of a user, and drawing an object which is written and generated according to the touch operation in the first view by using a first rendering mode;
the step S4 specifically comprises the following steps:
s411, if a second rendering mode is selected to be used, recording first object data, and emptying the first view; the first object data are data corresponding to all objects in the first view at present;
s412, drawing the object corresponding to the first object data on the second view by using a second rendering mode;
s413, monitoring touch operation of a user, and drawing an object which moves or zooms according to the touch operation by using a second rendering mode on the second view.
When the writing software is in a writing mode, as the writing handwriting generated by following the touch operation of a user or the picture inserted is not high in the requirement on the rendering speed, a rendering mode with good smooth effect and general rendering speed can be adopted, and the ideal rendering effect can be achieved; when moving, zooming the handwriting or picture and other objects, another rendering mode with high rendering speed is adopted, so that the problem that the rendering speed is blocked due to the fact that the rendering speed cannot keep pace with the operation speed can be avoided, and an ideal rendering effect can be achieved. On the android system, the rendering mode with good smooth effect is preferably surface view rendering, the rendering mode with fast rendering speed is preferably OpenGL rendering, namely the first rendering mode is preferably surface view rendering, and the second rendering mode is preferably OpenGL rendering. On other operating systems, other rendering modes may be selected as the first rendering mode and the second rendering mode.
When the OpenGL is used for rendering and drawing the handwriting, the OpenGL rendering has poor effect on the rough line rendering, and the smooth effect can be achieved by adopting the fixed line width for drawing and drawing the handwriting. Namely:
further, the object comprises a picture and handwriting; and when the appointed object is drawn on the second view by using a second rendering mode, if the object is handwriting, drawing the handwriting according to a preset line width by using the second rendering mode.
When the working mode is switched, all objects are switched to the other view, so that the problem of image overlapping errors can be avoided.
In a second embodiment of the rendering method provided by the present invention, the rendering method includes:
s1, configuring a first view and a second view on a canvas of writing software; wherein the first view and the second view both cover the canvas, and the backgrounds of the first view and the second view are transparent;
s2, selecting a rendering mode according to the object to be drawn;
s3, if the first rendering mode is selected to be used, drawing a specified object on the first view by using the first rendering mode;
and S4, if the second rendering mode is selected to be used, drawing the specified object on the second view by using the second rendering mode.
Fig. 3 is a specific flowchart of a second step S2 of the rendering method according to the present invention. The step S2 specifically comprises the following steps:
s221, if the object to be drawn is a zoom control point, selecting a first rendering mode; the scaling control point is defined as a control point which is generated on the edge of the picture according to clicking operation of a user and used for controlling the size of the picture;
s222, if the object to be drawn is a picture, selecting a second rendering mode for use.
In the second embodiment, in the android system, the first rendering mode is preferably surface view rendering, and the second rendering mode is preferably OpenGL rendering. On other operating systems, other rendering modes may be selected as the first rendering mode and the second rendering mode. In the second embodiment, a rendering mode is selected and used according to the type of the drawing object. For example, when a picture object in writing software is selected, 8 control points for controlling the size of a picture can be generated on the edge of the picture, the picture can be scaled through the control points, and the 8 control points can be rendered by using surface view rendering because the control points have relatively low requirements on hands, and the surface view rendering is easier to render; and the scaling of the picture is performed by using OpenGL rendering to avoid the condition of clamping. On the premise that the view is transparent, the content seen by the user is the overlapped content of the two views. In addition, the handwriting object can be rendered by using surface view rendering, so that the problem that the rendering effect of OpenGL rendering on handwriting is poor is avoided, namely, the step S2 further comprises:
s223, if the object to be drawn is handwriting, selecting to use a first rendering mode.
In a third embodiment of the rendering method provided by the present invention, the rendering method includes:

s3, if the first rendering mode is selected to be used, drawing a specified object on the first view by using the first rendering mode;
and S4, if the second rendering mode is selected to be used, drawing the specified object on the second view by using the second rendering mode.
Referring to fig. 4, a specific flowchart of a three-step S2 of the rendering method according to the present invention is shown.
The step S2 comprises the following steps:
s231, judging whether an object to be drawn is a target page with a page turning effect according to whether a page turning instruction for jumping from a current opened page to the target page is received;
s232, if the object to be drawn is not a target page with the page turning effect, selecting a first rendering mode;

the step S3 specifically comprises the following steps: if the first rendering mode is selected to be used, drawing an object generated, moved or zoomed by touch operation of a user on the first view by using the first rendering mode;
the step S4 specifically comprises the following steps: and if the second rendering mode is selected to be used, the first view is emptied, and the target page is drawn on the second view by using the second rendering mode.
In the third embodiment, in the android system, the first rendering mode is preferably surface view rendering, and the second rendering mode is preferably OpenGL rendering. On other operating systems, other rendering modes may be selected as the first rendering mode and the second rendering mode. In the third embodiment, openGL rendering is used for the page turning effect, so that the page turning speed is improved.
