Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The present invention filters and controls image by increase image filtering and control module in browser, reaches the more reasonably purpose of display web page of control browser.
Fig. 2 shows the method synoptic diagram according to a preferred embodiment of the present invention.As shown in Figure 2, comprise in the browser 201: syntax analyzer 202, composing layout modules 203, first interface function 205, second interface function 206, first image filtering and control module 207 and second image filtering and control module 208.The each several part function is: 202 pairs of hypertext documents of syntax analyzer (HTML) data are analyzed the judgment data type; First image filtering and control module 207 and second image filtering and control module 208 at the size positions characteristic of figure filter, dwindle, the cutting operation; The data manipulation that first interface function 205 is realized between syntax analyzer 202 and first image filtering and the control module 207; 203 pairs of data that receive of composing layout modules layout of setting type makes demonstration more attractive in appearance rationally; Second interface function 206 is realized the data manipulation between composing layout modules 203 and second image filtering and the control module 208.
When browser received hypertext document (HTML) page from the WEB website, browser began it is handled, and processing procedure mainly is divided into grammatical analysis and two stages of composing layout.
Data at first are sent to syntax analyzer 202, enter the syntactic analysis phase.202 pairs of html data files of syntax analyzer are analyzed, and are by name when running into＜IMG〉the HTML image tag time, syntax analyzer 202 is sent to first image filtering and control module 207 by first interface function 205 with view data.207 pairs of view data of first image filtering and control module are analyzed and are handled: according to the size of images position characteristic filter, dwindle, the cutting operation, make entire image to be presented on the low-resolution display devices.First image filtering and control module 207 are sent to syntax analyzer 202 with result by first interface function 205 then.Syntax analyzer 202 continues following data are analyzed, whenever to one＜IMG〉the HTML image tag, just give first image filtering and control module 207 processing with view data, all carried out processing up to 202 pairs of all data of syntax analyzer by first interface function 205.
The foundation of first image filtering and control module 207 deal with data is size of images position characteristics, is described in detail operation strategy below.
Fig. 3 shows according to image filtering operation chart of the present invention.Filter operation mainly is at the too little image of the size on a certain direction.
Before introducing the filter operation strategy, simply introduce the notion of pixel.Pixel (pixel) is made up of these two letters of image (picture) and element (element), is to be used for a kind of unit of computed image.Pixel is the least unit of dot matrix image, is a square dot.Computing machine is used the notion of pixel in the presentation graphic size, be exactly the size of point in fact, and general high-resolution display device is 640 * 480 pixels, as desktop computer, notebook computer etc.; The display device of low resolution is generally 240 * 320 pixels, as PDA, palm PC etc.
Shown in Fig. 3 (a), image 302 is compared very high very narrow with screen 301, and its transverse width is lower than 15 pixels; Shown in Fig. 3 (b), image 303 is compared very short very wide with screen 301, and it vertically highly is lower than 15 pixels; Shown in Fig. 3 (c), the size image 304 is compared laterally vertically with screen 301 on is all very little, all is lower than 15 pixels, just after first image filtering and control module 207 are handled these image filterings are fallen, these images will not show on screen 301.
Fig. 4 shows according to image reduction operation synoptic diagram of the present invention.Reduction operation mainly is at exceeding screen 301 indication ranges, and exceeds the many images of part.
Shown in Fig. 4 (a), image 401 has transversely exceeded the indication range of screen 301, its exceed the part transverse width the image overall width 1/5～1/2 between; Shown in Fig. 4 (b), image 402 has exceeded the indication range of screen 301 on vertically, its exceed the part vertical height the image overall height 1/5～1/2 between, after first image filtering and control module 207 processing, just these images are dwindled according to certain ratio, these images intactly are shown in the screen 301.
Fig. 5 shows according to image cutting operation chart of the present invention.Cutting operation mainly is at exceeding screen 301 indication ranges, and exceeds the fewer image of part.
Shown in Fig. 5 (a), image 501 has transversely exceeded the indication range of screen 301, and its transverse width that exceeds part is less than 1/5 of image overall width; Shown in Fig. 4 (b), image 502 has exceeded the indication range of screen 301 on vertically, its vertical height that exceeds part is less than 1/5 of image overall height, just the part cutting that these images is exceeded screen after first image filtering and control module 207 processing is fallen, a part that only keeps view data makes that remainder intactly is shown in the screen 301 after these image cuttings.
Syntactic analysis phase finishes, and data enter the composing layout stage.Based on the laxity of html language, in the syntactic analysis phase of browser, first image filtering and control module 207 can can't obtain attributes of images definitely, therefore have some view data and handle.For the processing that makes all images data is protected, introduce second image filtering and control module 208 at the composing layout stage, all images data are handled once more.
Data are sent to composing layout modules 203, enter the composing layout stage.203 pairs of html data files of composing layout modules layout of setting type, when running into view data, composing layout modules 203 is sent to second image filtering and control module 208 by second interface function 206 with view data.208 pairs of view data of second image filtering and control module are analyzed and are handled: according to the size of images position characteristic filter, dwindle, the cutting operation, its processing policy and first image filtering and control module 207 are just the same.
Based on above-mentioned structural principle, at low resolution device control browser display webpage, Fig. 6 shows the process flow diagram according to another preferred embodiment of the present invention.May further comprise the steps as shown in Figure 6:
Step 601～step 603: browser receives the web page files data stream.Syntax analyzer at first carries out grammatical analysis to web page files, judges whether whether these data are view data, promptly be＜IMG〉the HTML image tag.If, execution in step 610; If not, execution in step 604.
Step 604: syntax analyzer carries out analyzing and processing at the data that are not image.
Step 605: after syntax analyzer is handled current data, judge whether the back also has data, if having, execution in step 603 continues data are handled; If no, execution in step 606.
Step 606～step 607: syntax analyzer is sent to the composing layout modules with data, and after the composing layout modules received data, whether judgment data was view data.If, execution in step 612; If not, execution in step 608.
Step 608～step 609: data are sent to display module, and display module shows web page files.
Step 610～step 611: first image filtering and control module receive view data, according to the picture size position characteristic filter, dwindle, the cutting operation.
Step 612～step 613: second image filtering and control module receive view data, according to the picture size position characteristic filter, dwindle, the cutting operation.
Because the operation strategy of first image filtering and control module and second image filtering and control module is just the same, so can only adopt an image filtering and control module, start respectively in syntactic analysis phase and composing layout stage, realize filtration and size Control image.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
