Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Fig. 1 is a flowchart of a handwriting display method according to an embodiment of the present invention. As shown in fig. 1, includes:
step 101: and detecting the number of the touch points for writing input on the touch screen.
When the touch screen is used for writing, the user can write through a finger or a writing tool, and therefore the position where the finger or the writing tool is in contact with the touch screen is a contact point. In embodiments of the present invention, writing includes, but is not limited to: writing, drawing, editing, etc.
Step 102: and when the number of the contacts is more than or equal to two, switching the current color of the handwriting input according to a set sequence.
After the number of the touch points for writing input on the touch screen is detected, whether the number of the detected touch points is larger than or equal to two is judged, and if yes, the current color of the handwriting for writing input is switched according to a set sequence. The specific handwriting switching process may be various, for example: when one finger is in contact with the touch screen for writing input, one touch point exists, when another finger or a plurality of fingers click the touch screen, the existence of another touch point or a plurality of touch points is detected, and at the moment, the current color of the handwriting input by writing can be switched to a color adjacent to the current color or a color is switched immediately according to a set sequence. Thus, when one finger is writing an input, the current color of the note is switched each time another finger or fingers click on the touch screen. Of course, the current color of the handwriting input can be switched according to the specific number of the contacts.
As can be seen, the handwriting switching process may include: and switching the color of the handwriting from the current color to a first color according to the set sorting, wherein the first color is arranged behind the current color and is different from the sequence of the current color by one bit. Or switching the color of the handwriting from the current color to a second color according to the sorting, wherein the number of the touch points is n, and the second color is arranged behind the current color and has a difference of n-1 bits with the sequence of the current color.
According to the technical scheme provided by the embodiment of the invention, when the number of the contacts on the touch screen is more than or equal to two, the colors of the handwriting can be switched, namely when a single contact is used for writing, the colors of the handwriting can be switched by adding other contacts, so that the colors of the handwriting can be selected without frequently clicking color options in order to display the handwriting more abundantly in the writing process, the switching process is saved, the writing input speed is improved, and better writing experience is provided for a user.
For ensuring continuity of color switching during handwriting display, in one embodiment, after step 102, the switched color is determined as the current color. In the above embodiment, or in another embodiment, at least two colors may be preset and each color may be sorted before step 101. Therefore, due to the fact that the preset colors are two or more, the diversity of handwriting color switching is enriched.
In the second embodiment, when one touch point is used for writing input, as long as two or more touch points are detected, the current color of the handwriting is switched to the next color adjacent to the current color during handwriting display. Referring to fig. 2, the process of handwriting display in the embodiment includes:
step 201: and detecting the number of the touch points for writing input on the touch screen.
When writing on the touch screen, the number of contacts on the touch screen is recorded.
Step 202: and judging whether the number of the detected contacts is more than or equal to 2, if so, executing the step 203, otherwise, ending the handwriting color switching process.
Step 203: and switching the color of the handwriting from the current color to a first color according to a set sequence, wherein the first color is arranged behind the current color and is different from the sequence of the current color by one bit.
When writing on the touch screen, a single contact is generally adopted for writing input, and when other contacts are detected, the color of the handwriting can be switched. The description will be given taking an example in which a finger touches a touch panel. When a single finger is used for writing input on the touch screen, another finger is used for clicking the touch screen, and at the moment, two contacts are detected on the touch screen, and the current color of the handwriting input by writing is switched. Of course, the same is true for clicking the touch screen with another two or three fingers, and the current color of the handwriting to be input is switched.
Before detecting the number of touch points of writing input on the touch screen, at least two colors can be preset, and each color is sequenced, for example: arranged in the order of black, red, blue, green ┈, etc. Thus, writing input is carried out on the touch screen by a single finger, the color of the handwriting is red, when another finger or two fingers click on the touch screen, the number of detected touch points is greater than or equal to 2, namely, the color of the handwriting is switched from red to blue which is arranged behind the red and has a bit difference with the red in sequence, and the blue is the first color.
In this embodiment, after the current color of the input handwriting is switched, the switched first color may be determined as the current color. Therefore, switching the current color of the note may be performed again after that, when the single finger or/and the multi-finger clicks the touch screen, when the single finger performs writing input on the touch screen. Specifically, the writing of blue is switched to the note of green, which is the first delay because it is lined up behind blue and out of order by one bit.
According to the process, the colors of the handwriting can be sequentially switched, and the handwriting is not listed one by one, so that in the embodiment, when a single finger is used for writing input on the touch screen, the color of the handwriting can be switched once when other fingers click the touch screen once, the color of the output written note is diversified, in addition, the switching process only needs to click the touch screen once through the finger, the existing handwriting color switching process is greatly simplified, and the writing input speed is improved.
Example three: in this implementation, the current color of the handwriting can be switched to the color corresponding to the number of the contacts according to the specific number of the contacts. Referring to fig. 3, the handwriting display process includes:
step 301: and detecting the number of the touch points for writing input on the touch screen.
The number of the touch points for writing input on the touch screen can be detected, and the number of the touch points is n.
Step 302: and judging whether the number of the detected contacts is more than or equal to 2, if so, executing the step 303, and otherwise, finishing the handwriting color switching process.
Step 303: and switching the color of the handwriting from the current color to a second color according to the sorting, wherein the second color is arranged behind the current color and is different from the sequence of the current color by n-1 bits.
Also, at least two colors are preset and each color is sorted, for example: black, red, blue, green, purple ┈, etc. are arranged in this order. Thus, writing input is carried out on the touch screen by a single finger, the color of the handwriting is red, when another finger or a plurality of fingers contact the touch screen, the total number of the contacts is n, n is more than or equal to 2, and the color of the handwriting is switched from red to the color of n-1 bit behind the red in sequence with the red. Specifically, if there are two fingers on the touch screen, and n is equal to 2, the color of the handwriting is switched from red to blue, which is 1 bit behind red in sequence with red, and at this time, blue is the second color. If three fingers exist on the touch screen at the same time, and n is equal to 3, the color of the handwriting is directly switched from red to green with 2 bits behind the red in sequence. Where green is the second color. If four fingers exist on the touch screen at the same time, and n is equal to 4, the color of the handwriting is directly switched from red to purple which is 3 bits behind the red in sequence with the red, and the purple is the second color at the moment. The following is not mentioned.
In this embodiment, after switching, the second color after cutting may also be determined as the current color, so as to ensure the continuity of color switching later.
In the implementation, the color corresponding to the number of the contacts can be switched according to the specific number of the contacts, and the individual switching is not needed, so that the speed of handwriting color switching is increased, and the accuracy of the handwriting color switching is also improved. Thereby improving the speed and accuracy of handwriting input.
The second embodiment and the third embodiment take finger writing input as an example, but the embodiment of the present invention is not limited to this, and writing input may also be performed by using a writing tool, and a touch point is generated with the touch screen, and when the touch point is equal to or more than two, the color of the handwriting of the writing input may be switched. Of course, the second embodiment and the third embodiment are respectively two different setting orders, but the embodiment of the present invention is not limited thereto, and other setting orders may also be adopted, for example, a random order, that is, when the number of the touch points is greater than or equal to two, the current color of the handwriting input by writing is randomly switched to another color.
