Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in other embodiments," etc. in various places in this specification are not necessarily All refer to the same embodiment, but mean "one or more but not all embodiments" unless specifically emphasized otherwise. The terms "including", "including", "having" and their variants mean "including but not limited to" unless specifically emphasized otherwise.

In the printing function of the electronic device, there are few printing parameters for the user to set, so that the printing function of the electronic device is relatively simple and cannot meet the printing demand of the user. If the user is provided with the authority to configure the printing parameters, due to the complicated setting of the printing parameters, the configuration of the printing parameters will be incorrect, resulting in poor printing results or even printing errors.

To this end, the present application provides a picture printing method, wherein a corresponding printing template is determined according to the number of pictures to be printed and the characteristics of the pictures to be printed, wherein the characteristics of the pictures to be printed include any of the size, content, and pixels of the pictures to be printed. one or more. When receiving the printing instruction, the picture to be printed is processed according to the printing parameters corresponding to the printing template, the processed picture to be printed is sent to the printer, and the printer is instructed to print the processed picture to be printed. Compared with selecting printing parameters, selecting a printing template can reduce the problems of printing failure and poor printing effect caused by wrong parameter selection. At the same time, since the printing template is determined according to the number and characteristics of the pictures to be printed, the corresponding The matching degree between the printing parameters and the to-be-printed picture is better. After processing the to-be-printed picture according to the printing parameters corresponding to the printing template, and then printing, a better printing effect can be obtained.

The image printing method provided by the embodiment of the present application is exemplarily described below.

The picture printing method provided by the embodiment of the present application is applied to an electronic device.

Exemplarily, the electronic devices described in the embodiments of the present application may be mobile phones, wearable devices (such as smart watches, smart bracelets, smart glasses, smart jewelry, etc.), tablet computers, in-vehicle devices, augmented reality (AR) )/virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), and other electronic devices that can connect to printers. The above electronic devices include but are not limited to devices equipped with iOS ^® , Android ^® , Microsoft ^® , Harmony OS or other operating systems. The embodiments of the present application do not limit any specific types of electronic devices.

The picture printing method provided by the embodiments of the present application can be applied to various types of picture printing scenarios. Taking the electronic device as a mobile phone as an example below, some application scenarios are introduced in conjunction with the accompanying drawings.

Scenario 1: Big Picture Printing Scenario

Exemplarily, as shown in FIG. 1A , when the mobile phone detects an operation of opening a gallery application, it displays a gallery preview interface as shown in FIG. 1B , and the gallery preview interface displays pictures stored in the mobile phone. In the gallery preview interface, if an operation of selecting a picture is detected (for example, the operation of long-pressing the picture), the selected picture will be marked. For example, as shown in Figure 1C, a "√" mark is added to the selected image. After selecting a picture, the gallery preview interface displays picture operation options, and you can perform corresponding processing on the picture by clicking the picture operation option. For example, as shown in FIG. 1C , the picture operation options include "share", "select all", "copy", and "more" options. If the operation of clicking "Share" is detected, the mobile phone opens the sharing interface. As shown in Figure 1D, the sharing interface displays the selected picture and displays sharing options such as "Information", "Email", "Bluetooth", "Print", etc. The user can open another process by clicking any sharing option to send Or print selected pictures. When the mobile phone detects the operation of clicking "Print", the printing process is opened, and the selected picture is used as the picture to be printed. Exemplarily, the picture to be printed is one piece, and the mobile phone determines that the picture to be printed conforms to the large picture printing template according to the size and resolution of the picture to be printed, and displays the large picture printing interface as shown in FIG. Displays pictures to be printed.

In one embodiment, the mobile phone determines the number of images to be printed that need to be cropped according to the zoom ratio and the size of the paper, and displays them on the large image printing interface. For example, as shown in FIG. 1E , a dividing line is displayed on the picture to be printed, and the dividing line divides the picture to be printed into 4 sub-pictures.

In the large image printing interface, if the operation of clicking "Start Printing" is detected, the mobile phone will process the to-be-printed image according to the printing parameters corresponding to the large image printing template, and obtain 4 sub-images, instructing the printer to print the 4 sub-images in sequence. Among them, the processing of the picture to be printed includes scaling, cropping, filling and other processing. After the user obtains the printed 4 sub-images, splicing the 4 sub-images can obtain a complete large image.

In one embodiment, the large-picture printing interface displays some printing parameters corresponding to the large-picture printing template. For example, the printing parameters displayed on the large-picture printing interface include: the logo of the currently connected printer "HP Laser M330", and the mode "A4 paper". /B&W/1copy/Portrait", and the zoom ratio "Zoom in 2 times". Among them, A4 paper in the mode represents the paper size, black and white represents the color, 1 copy represents the number of prints, and vertical represents the arrangement direction. In one embodiment, the user can modify some printing parameters corresponding to the large image printing template. For example, in the large image printing interface, the mobile phone responds to the user's operation of clicking "printer selection" to enter the printer page for the user to select a printer. Alternatively, the mobile phone enters the mode page in response to the operation of clicking "mode", and modifies the paper size, color, print quantity and arrangement direction according to the user's modification operation. Alternatively, the mobile phone enters the zoom ratio page to reset the zoom ratio in response to the operation of clicking the "zoom ratio" triggered by the user. Exemplarily, if an operation of clicking "zoom ratio" is detected, the mobile phone displays a zoom ratio setting page as shown in FIG. 1F . On the zoom ratio setting page, the user can select the zoom ratio option to reset the zoom ratio. For example, the currently selected zoom ratio is "zoom in by 2 times", and if it is detected that the user clicks the operation of "zoom in by 1 time", the zoom ratio is modified to zoom in by 1 times. If the operation of clicking the "Cancel" option is detected, the mobile phone returns to the large image printing interface. If an operation of modifying the printing parameters by the user is received, when the operation of clicking "start printing" is detected, the mobile phone processes the picture to be printed according to the modified printing parameters.

Optionally, when detecting the user's operation of modifying the printing parameters, the mobile phone may also prompt the user whether to save the large image printing template after the modification of the printing parameters. In the case of detecting that the user instructs to save the large-picture printing template with the modified printing parameters, the mobile phone saves the large-picture printing template with the modified printing parameters. If it is detected that the user instructs not to save the large image printing template after the modification of the printing parameters, the mobile phone does not save the large image printing template after the modification of the printing parameters. Subsequent users may choose to use one of the large image printing template with the modified printing parameters and the large image printing template without modified parameters as the default large image printing template.

In one embodiment, the positions of the sub-images may be marked on each sub-image printed by the printer, so as to facilitate the user to perform splicing. For example, the row number and column number where the subgraph is located, or the page number where the subgraph is located can be identified.

As shown in FIG. 2A , in one embodiment, the large image printing interface also displays an option of "splicing mark", and the mobile phone is used to mark the sub-pictures according to the parameters of the splicing mark, and instruct the printer to print the marked sub-pictures. Users can view the parameters of the splice logo and edit the parameters of the splice logo. For example, if it is detected that the user clicks on the option of "splicing logo", the interface of splicing logo as shown in FIG. 2B is opened. In the splicing logo interface, a variety of splicing logo formats are displayed. For example, the format of the splice logo includes a default format and a custom format. The parameters of the default format are blank 2 rows and 2 columns, here are p rows and q columns. Wherein, the blank space represents the blank area left around the divided sub-images. Here, the p row and the q column represent the splicing marks marked on the subgraph. The parameters corresponding to the custom format can be input by the user. For example, the names of the custom formats added by the user are Mode 1, Mode 2, and Custom 1, respectively. The parameters of the format of mode 1 are blank 2 rows and 2 columns, where p row and q column are connected; the parameters of the format of mode 2 are blank 0 rows and 0 columns, none; the parameters of the custom 1 format are blank 1 row 1 column, p row q column. At the same time, the mobile phone displays the sub-image style after adding the splicing logo on the splicing logo interface according to the currently selected splicing logo format, and the user can click the preview button to browse the print effects corresponding to the divided sub-images in turn. For example, if the currently selected splicing ID is the default, and the currently previewed sub-image is a sub-image located in 2 rows and 2 columns, "here is 2 rows and 2 columns" will be displayed on the surrounding edges of the sub-image.

Scenario 2: Long Image Printing Scenario

Exemplarily, as shown in FIG. 3A and FIG. 3B , on the gallery preview interface, if an operation of selecting a picture is detected, a "√" mark is added to the selected picture. After a picture is selected, the gallery preview interface displays picture operation options. For example, as shown in FIG. 3B , the picture operation options include "share", "select all", "copy", and "more" options. If an operation of clicking "Share" is detected, the mobile phone displays a sharing interface as shown in FIG. 3C . The sharing interface displays the selected picture, as well as sharing options such as "Information", "Email", "Bluetooth", "Print". If the operation of clicking "print" is detected, the mobile phone starts the printing process, and takes the selected picture as the picture to be printed. Exemplarily, the picture to be printed is one piece, and the mobile phone determines that the picture to be printed conforms to the long picture printing template according to the size and resolution of the picture to be printed, and displays the long picture printing interface as shown in FIG. Image to be printed. The long-image printing interface also displays some printing parameters corresponding to the long-image printing template. For example, the printing parameters displayed in the long-image printing interface include: the logo of the currently connected printer "HP Laser M330", the mode "A4 paper/color/1 copy" /portrait", zoom ratio "1x zoom". At the same time, the mobile phone determines that the picture to be printed needs to be divided into 2 sub-pictures according to the size of the picture to be printed and the size of the paper used for printing, and displays a dividing line on the picture to be printed, and the dividing line divides the picture to be printed into 2 sub-pictures.

If the operation of clicking "Start Printing" is detected, the mobile phone processes the picture to be printed according to the printing parameters corresponding to the long picture printing template, and obtains 2 sub-pictures, instructing the printer to print the 2 sub-pictures in sequence. After the user obtains the two printed sub-images, splicing the two sub-images can obtain a complete long image. In one embodiment, the user can modify the printing parameters corresponding to the long-picture printing template on the long-picture printing interface. If an operation of modifying the printing parameters is detected, the subsequent mobile phone processes the pictures to be printed according to the modified printing parameters. In one embodiment, the mobile phone adds a splicing mark on each sub-picture according to a preset splicing mark, for example, the splicing mark can be a page number, the mobile phone instructs the printer to print the sub-picture after adding the page number, and the user can determine each sub-picture according to the page number. position for easy splicing.

Scenario 3: inch photo printing scenario

Exemplarily, as shown in FIG. 4A and FIG. 4B , on the gallery preview interface, if an operation of selecting a picture is detected, a "√" mark is added to the selected picture. After selecting a picture, the gallery preview interface displays the picture operation options "Share", "Select All", "Copy", and "More" options. If an operation of clicking "Share" is detected, the mobile phone displays a sharing interface as shown in FIG. 4C . The sharing interface displays the selected picture, as well as sharing options such as "Information", "Email", "Bluetooth", "Print". If the operation of clicking "print" is detected, the mobile phone will start the printing process and use the selected picture as the picture to be printed. Exemplarily, the picture to be printed is one piece, and the mobile phone determines that the picture to be printed conforms to the inch photo printing template according to the size and content of the picture to be printed, and displays the inch photo printing interface as shown in FIG. Printed photo. In one embodiment, the mobile phone determines the number of pictures to be printed that can be arranged on the paper according to the size of the picture to be printed and the size of the paper, and displays the effect of arranging multiple pictures to be printed on the paper on the inch photo printing interface. The inch photo printing interface also displays some printing parameters corresponding to the inch photo printing template. For example, display the logo of the currently connected printer "HP Laser M330", the mode is "photo paper/color/4*6/portrait", and the zoom ratio is "1x magnification". If the operation of clicking "start printing" is detected, the mobile phone processes the picture to be printed according to the printing parameters corresponding to the inch photo printing template, and instructs the printer to print the processed picture to be printed. In one embodiment, the user can modify the printing parameters corresponding to the photo printing template on the photo printing interface. If an operation of modifying the printing parameters is detected, the subsequent mobile phone processes the pictures to be printed according to the modified printing parameters.

Scenario 4: Landscape print scenario

Exemplarily, as shown in FIG. 5A and FIG. 5B , on the gallery preview interface, if an operation of selecting a picture is detected, a mark of "√" is added to the selected picture. After selecting a picture, the gallery preview interface displays the picture operation options "Share", "Select All", "Copy", and "More" options.

In another embodiment, after determining the target printing template, the electronic device outputs the printing parameters corresponding to the target printing template. The output printing parameters may be voice prompts for printing parameters, or may be displayed on a display interface, so as to facilitate the user to confirm the printing parameters. After outputting the printing parameters corresponding to the target printing template, if the electronic device detects a printing instruction, the electronic device uses the picture processing parameters corresponding to the target printing template to process the to-be-printed picture. Exemplarily, referring to Figure 1E, Figure 3D, Figure 4D, Figure 5D, Figure 6D, Figure 7C, Figure 8C, after the electronic device determines the target printing template, it displays the printing parameters corresponding to the target printing template on the display interface.

Specifically, the electronic device sends the document in PDF format obtained according to the processed picture to be printed and the printer parameters to a printer that is communicatively connected to the electronic device, and the printer prints the document in PDF format according to the printer parameters. The printer that receives the print instruction may be determined according to the print template, or may be determined according to the user's printer selection instruction.

Since each printing template corresponds to a set of picture processing parameters, Therefore, the subsequent electronic device can process the to-be-printed image based on the image processing parameters corresponding to the target print template, and then instruct the printer to print the processed to-be-printed image. In this solution, since each print template corresponds to a set of print parameters, this method is used to print The user can avoid inputting printing parameters when taking pictures. Compared with selecting printing parameters, selecting a printing template can reduce the problems of printing failure and poor printing effect caused by wrong parameter selection.
