Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.Owing to the invention discloses the screen content choosing method of a kind of electronic reader and electronic reader; Wherein employed electronic reader correlation technique and relative configurations principle have been that those of ordinary skills can understand; So, no longer do complete description with explanation hereinafter.Simultaneously,, be intended to express the implication with the relevant structure of characteristic of the present invention with the accompanying drawing that is hereinafter contrasted, also need be according to the complete drafting of physical size, statement formerly.
First embodiment: the screen content choosing method of electronic reader
The present invention at first proposes a kind of screen content choosing method of electronic reader, please refer to process flow diagram shown in Figure 1, and key step is following:
Step 101 : beginning.
Step 102 : load document, the position generation page pel according to the character in the document with the storage of page primitive information, generates corresponding page pel chained list.
Step 103 : frame selects page pel, changes the luminance state of the page pel in the selection range, and changes the brighter pel chained list of new peak according to the luminance state of each page pel.
Step 104 : finish.
Specify as follows:
Before step 102, also comprise being converted into unified coded format after the document parsing.In the present embodiment, document coded format by UTF8 after resolving is encoded.
In step 102, document is loaded into electronic reader; System default font (generally being stored under the fonts catalogue) according to electronic reader; With page literal is that index finds the corresponding lattice information of literal in the system font file of electronic reader; And from lattice information, extract the height and the width value of respective symbols, again according to the height and the width of the page, just can calculate the positional information of all characters on certain page; Form page pel, each page pel is formed page pel chained list.
Said page pel chained list includes a plurality of nodes, and each node is each page pel of correspondence respectively, stores length and width, screen relative coordinate, riser portions, falling portion and the encoded radio of each page pel respectively.As shown in Figure 2, the length of this page pel is 25pix, and wide is 20pix, and the screen relative coordinate is (119,412), and riser portions and falling portion are 4, and the UTF8 encoded radio is 汉, and the ID that this page pel is corresponding is 93.
Said page pel also comprises the form control information, has comprised following content:
1. the writing direction of this page pel. the character that is used for confirming this page pel is that (LTR) sets type or (RTL) sets type from right to left from left to right when setting type.
2. this page pel rank of corresponding title or title whether, be used for confirming this character whether needs placed in the middle show and the adjustment font size big or small.
3. whether this page pel has the requirement of other special display effects such as underscore, black matrix or italic demonstration.
In step 103; When said frame selects page pel; Coordinate and the page pel of writing implement being started to write, lifted the pen generation compare; Filter out a page pel of starting to write, lift the coordinate place that pen produces respectively, because page pel stores with the chain sheet form and form page pel chained list, each node in the page pel chained list is respectively in proper order to each page pel in should the page.The user starts to write, lifts the page pel at the coordinate place of pen and distinguish two nodes in the corresponding page pel chained list, the selection range of the corresponding page of each node between these two nodes when document is taken passages.
Call the interface that the figure user interface of electronic reader provides, can the above-mentioned page be plotted on the screen of electronic reader, as shown in Figure 4.
Please select process flow diagram with reference to frame shown in Figure 3 again; At first be step 103a; The user operates writing implement (for example writing pencil) and on screen, carries out frame choosing, and so-called frame choosing is exactly to write down the writing implement operation from starting to write, slide, constituting selection range to lifting the pen formed track on screen.If this moment, option one 03b was then carried out in frame choosing action first, the page pel in the selection range all is designated high bright state, as shown in Figure 5, and these page pels are added in the high bright pel chained list.If this moment of frame choosing once more (that is previous frame choosing record has been arranged) then selects resulting page pel to remove to compare high bright pel chained list frame, and is as shown in Figure 6; If page pel just was regarded as anti-choosing in the bright pel chained list of height (that is having been selected by frame), carry out option one 03c, remove its high bright state to these page pels, as shown in Figure 9, and from the bright pel chained list of height, delete; If not in the bright pel chained list of height, just be regarded as by-election by the page pel of frame choosing, carry out option one 03d, these page pels all are designated high bright state, like Fig. 7 and shown in Figure 8, and add in the high bright pel chained list.Then, the user can determine the end block choosing or continue the frame choosing, if will continue the frame choosing, then gets back to step 103a, carries out the step of frame selection word, otherwise promptly finishes.
As shown in Figure 5; The user operates writing implement and on screen, starts to write, slides into the A2 place, lifts pen from A2 then from A1; At this moment because be frame choosing first,, and add in the high bright pel chained list so the literal between from A1 to A2 all changes to high bright state from normal condition.Each node in the bright pel chained list of said height is the interior page pel of corresponding selection range respectively; When clicking A1; From page pel chained list, choose A1 corresponding page pel; After sliding into the A2 place, choose A1 to A2 place corresponding page pel in the page pel chained list, and these page pels are added paramount bright pel chained list.Electronic reader carries out high bright demonstration according to the high bright pel chained list that obtains to each page pel.
As shown in Figure 6, user's frame choosing is once more started to write, is slided into the B2 place, lifts pen from B2 then from B1 on screen.From figure, very clearly see; The pel of B1 between B2 is different fully when frame selects first, thus B1 to the pel between the B2 not in the bright pel chained list of height, just be regarded as by-election this moment; B1 also changes to high bright state from normal condition to the pel between the B2, and adds in the high bright pel chained list.Each node in the bright pel chained list of said height is the page pel in the corresponding selection range respectively, and electronic reader will change to be started to write, lift the page pel that coordinate that pen produces belongs to before and after the selection range and compare.When clicking B1; Because among the A1 to A2 that B1 corresponding page pel is not chosen in the page pel chained list place corresponding page pel; After sliding into the B2 place; Among A1 to A2 that B2 corresponding page pel is not also chosen in the page pel chained list place corresponding page pel, because the selection range corresponding page pel sequential storage in chained list between the B1, B2, and B1, B2 are in a side of A1 to A2 place corresponding page pel; Represent that then corresponding B1 to B2 place corresponding page pel forms a new high bright pel chained list, and should not overlap with the high bright pel chained list that A1 to A2 place corresponding page pel forms by the bright pel chained list of height.Electronic reader carries out high bright demonstration according to two high bright pel chained lists that obtain to A1 to A2 place's corresponding page pel and B1 to B2 place corresponding page pel.
As shown in Figure 7; If the choosing of user's frame once more is to start to write, slide into the B2 place, lift pen from B2 then from B1; From figure, very clearly see; The pel of B1 between B2 followed when frame selects first different, so B1 also changes to high bright state from normal condition to the pel between the B2, and adds in the high bright pel chained list.But since the place of starting to write of B1 just for frame choosing first lift the A2 of pen place, so A1 is just to link together to A2, B1 to B2, electronic reader will change the selection range front and back and start to write, lifts a page pel that the coordinate of generation belongs to and compare.When clicking B1; Because among the A1 to A2 that B1 corresponding page pel is not chosen in the page pel chained list place corresponding page pel; B1 corresponding page pel overlaps with A2 corresponding page pel; After sliding into the B2 place, among A1 to the A2 place corresponding page pel that B2 corresponding page pel is not also chosen in page pel chained list, owing to the selection range corresponding page pel sequential storage in chained list between B1, the B2; And B1, B2 locate a side of corresponding page pel at A1 to A2; Represent that then corresponding B1 to B2 place corresponding page pel forms a new high bright pel chained list, and should link to each other the page pel at high bright pel chained list corresponding A 1 to the B2 place of formation with the high bright pel chained list that A1 to A2 place corresponding page pel forms by the bright pel chained list of height.Electronic reader carries out high bright demonstration according to the high bright pel chained list that obtains after merging to A1 to B2 place corresponding page pel.
As shown in Figure 8, if the choosing of user's frame once more is to start to write, slide into the B2 place, lift pen from B2 then from B1, electronic reader will change selection range, and the page pel of front and back being started to write, lifted the coordinate place of pen generation compares.As can be seen from the figure; B1 to the pel between the B2 with frame first select A1 to A2 have some overlappings page pel (B1 is to A2), some page pels that do not overlap (A1 to B1, A2 to B2) are arranged; When clicking B1; Because among the A1 to A2 that B1 corresponding page pel is chosen in the page pel chained list place corresponding page pel; B1 to A2 corresponding page pel overlaps, slide into B2 place after, the A1 to A2 that B2 corresponding page pel is not also chosen in page pel chained list locates among the corresponding page pel; Then the high bright pel chained list of B1 to B2 place new high bright pel chained list of corresponding page pel formation and the corresponding page pel formation of A1 to A2 place merges; Be that B1 to A2 corresponding page pel overlaps, the chained list node that B1 to A2 corresponding page pel is corresponding also merges the page pel at high bright pel chained list corresponding A 1 to the B2 place of formation.Electronic reader carries out high bright demonstration according to the high bright pel chained list that obtains after merging to A1 to B2 place corresponding page pel.Since the page pel corresponding nodes at B1 to A2 place after merging still in the bright pel chained list of the formed height of A1 to B2 corresponding page pel; Then these overlapping page pels (B1 is to A2) continue to keep high bright state, and each page pel corresponding figures metamessage is not done change.
As shown in Figure 9, if the choosing of user's frame once more is to start to write, slide into the C2 place, lift pen from C2 then from C1, electronic reader will change selection range, and the page pel of front and back being started to write, lifted the coordinate place of pen generation compares.As can be seen from the figure, C1 is to the page pel (C1 is to C2) that overlapping is arranged in the B2 with selection range A1 between the C2, and then C1 and C2 corresponding page pel are among the corresponding high bright pel chained list of the page pel at A1 to B2 place.When clicking C1 corresponding page pel and sliding to C1 corresponding page pel; C1 and C2 corresponding page pel are deleted in the corresponding high bright pel chained list of the page pel at A1 to B2 place, and the corresponding high bright pel chained list of page pel at former A1 to B2 place becomes two corresponding high bright pel chained lists of page pel at A1 to C1 and C2 to B2 place.Electronic reader carries out high bright demonstration to A1 to C1 place, C2 to B2 place corresponding page pel respectively according to the high bright pel chained list that obtains after cutting apart.
In other embodiments, high bright pel chained list and page pel chained list doubly linked list each other.After the user specifies selection range, in the page pel chained list the pairing node of the page pel in the selection range is added backward pointer, formation and page pel chained list be the high bright pel chained list of doubly linked list each other.
Method proposed by the invention can be supported multi-pass operations; Its remarkable advantage is to select, adjust, to merge function such as a plurality of zones in that the enterprising row of literal fragment of the choosing of frame is counter; Can let the user once can obtain own interested literal fragment accurately, save user's time, strengthened operating efficiency.
