[0030] Embodiment 1

[0031] Figure 1 This is a flowchart of an image generation method provided in the first embodiment of the present invention. This embodiment is applicable to the case of dynamically adjusting the text format of an electronic invoice. The method can be executed by an image generation device, which can be implemented in the form of hardware and / or software. The image generation device can be configured in an electronic device such as a terminal or a server. Figure 1 As shown, the method includes:

[0032] S110, obtaining an invoice target area to be filled with text, and determining the width and height of the invoice target area.

[0033] In the embodiment of the present invention, the invoice target area may be a purchaser information display area, a seller information display area, a password information display area, or a note information display area, etc., which is not specifically limited here.

[0034] Exemplarily, the border of the purchaser information display area of ​​the electronic invoice is identified to obtain the width and height of the purchaser information display area. The same is true for other areas, which will not be elaborated here.

[0035] S120, obtaining text content to be filled into the target area of ​​the invoice, and determining the width and height of the text content.

[0036] In the embodiment of the present invention, the text content may be a password, user name, taxpayer identification number, address, telephone number, bank account opening bank and account number, etc., which is not specifically limited here.

[0037] Exemplarily, the text content to be filled in the target area of ​​the invoice can be read from a preset file path, and then the size of the text content at the initial font size can be identified through the imagettfbbox function or other size measurement functions to obtain the width and height of the text content, wherein the initial font size can be 40px or other font sizes, which are not specifically limited here. It should be noted that 40px is a large font compared to other fonts, and font adjustment starting from a large font helps to improve the adaptability of text in the image.

[0038] S130: Adjust the text format based on the width and height of the invoice target area and the width and height of the text content.

[0039] S140. When the width of the text content after the text format is adjusted is not greater than the width of the invoice target area, and the height of the text content after the text format is adjusted is not greater than the height of the invoice target area, fill the text content after the text format is adjusted into the invoice target area to obtain a target invoice image.

[0040] In the embodiment of the present invention, by comparing the size of the invoice target area with the text content, the text content after the text format adjustment is filled into the invoice target area while ensuring that the text content does not exceed the invoice target area, so as to maintain the readability and aesthetics of the electronic invoice image. The target invoice image refers to the electronic invoice image with the text content drawn.

[0041] The technical solution of the embodiment of the present invention obtains the invoice target area to be filled with text, determines the width and height of the invoice target area, and then obtains the text content to be filled in the invoice target area, determines the width and height of the text content, and then adjusts the text format based on the width and height of the invoice target area and the width and height of the text content. When the width of the text content after the text format adjustment is not greater than the width of the invoice target area, and the height of the text content after the text format adjustment is not greater than the height of the invoice target area, the text content after the text format adjustment is filled into the invoice target area to obtain the target invoice image. The above technical solution adjusts the text format through size comparison, realizes dynamic adjustment of the text content, ensures that the text content does not exceed the invoice target area, reduces the complexity of manual adjustment, and improves the display effect of the invoice image.

[0042] Embodiment 2

[0043] Figure 2A flowchart of an image generation method provided for Embodiment 2 of the present invention, the method of this embodiment can be combined with the various optional schemes in the image generation method provided in the above embodiments. The image generation method provided in this embodiment is further optimized. Optionally, the text format adjustment based on the width and height of the invoice target area and the width and height of the text content includes: adjusting the font size based on the width and height of the invoice target area and the width and height of the text content; and / or adjusting the text line break based on the width and height of the invoice target area and the width and height of the text content.

[0044] like Figure 2 As shown, the method includes:

[0045] S210: Acquire an invoice target area to be filled with text, and determine the width and height of the invoice target area.

[0046] S220: Obtain text content to be filled into the target area of ​​the invoice, and determine the width and height of the text content.

[0047] S230, adjusting the font size based on the width and height of the invoice target area and the width and height of the text content; and / or adjusting the text line break based on the width and height of the invoice target area and the width and height of the text content.

[0048] S240: When the width of the text content after the text format is adjusted is not greater than the width of the invoice target area, and the height of the text content after the text format is adjusted is not greater than the height of the invoice target area, fill the text content after the text format is adjusted into the invoice target area to obtain a target invoice image.

[0049] In the embodiment of the present invention, the font size and / or line wrapping of the text content may be adjusted so that the text content does not exceed the invoice target area, thereby improving the display effect of the invoice image.

[0050] Optionally, the font size is adjusted based on the width and height of the invoice target area and the width and height of the text content, including: if the width of the text content is larger than the width of the invoice target area, the font size of the text content is reduced until the width of the text content is no larger than the width of the invoice target area, and the font size of the text content is stopped; and / or, if the height of the text content is larger than the height of the invoice target area, the font size of the text content is reduced until the height of the text content is no larger than the height of the invoice target area, and the font size of the text content is stopped.

[0051] It is understandable that if the width of the text content is greater than the width of the invoice target area, or the height of the text content is greater than the height of the invoice target area, it means that the text content has exceeded the invoice target area, and the font size of the text content needs to be reduced, thereby reducing the overall width of the text content or the overall height of the text content, so as to arrange the text content within the invoice target area.

[0052] Exemplarily, if the width of the text content is greater than the width of the invoice target area, the font size of the text content is cyclically reduced until the width of the text content is no greater than the width of the invoice target area, and the font size reduction of the text content is stopped.

[0053] In some optional embodiments, the height of the text content may be the height of all lines. Specifically, the height of a single line of text may be calculated by imagettfbbox, and then the height of the single line of text may be multiplied by the number of lines to obtain the height of the text content.

[0054] Optionally, text line wrapping is adjusted based on the width and height of the invoice target area and the width and height of the text content, including: segmenting the text content to obtain multiple words in the text content; adding the multiple words in the text content to the current line character string in sequence, and when the width of the current line character string is greater than the width of the invoice target area, adding the excess text in the current line character string to the next line character string, and continuing to add the remaining words to the next line character string.

[0055] In the embodiment of the present invention, the word may be Arabic numerals, English letters, Chinese characters, symbols or a combination of the above, which is not specifically limited here. The current line character string refers to a character string used to store the text content of the current line.

[0056] Exemplarily, the text content can be segmented based on spaces or punctuation marks to obtain multiple words in the text content, and the multiple words in the text content are stored in a word list so that the words can be added to the current line string one by one for line break judgment. Further, an empty string, that is, the current line string, is initialized to store the text content of the current line. Further, the word list is traversed to add multiple words to the current line string in sequence. Further, the width of the current line string is calculated. When the width of the current line string is greater than the width of the invoice target area, it indicates that the current line string exceeds the width of the invoice target area, and the current line string can be saved in a line list, wherein the line list is used to save the text content of all lines, and then the excess text in the current line string is added to the next line string, and the remaining words are continued to be added to the next line string.

[0057] Optionally, adding the excess text in the current line of string to the next line of string includes: determining the excess spaces and / or punctuation marks in the current line of string; and adding the text after the excess spaces and / or punctuation marks in the current line of string to the next line of string.

[0058] The punctuation marks may be commas, semicolons, and periods, etc., which are not specifically limited here. It should be noted that by giving priority to line breaks with spaces and / or punctuation marks, it is possible to ensure that the end of a line ends with a complete word or punctuation mark, thereby increasing the readability of the text layout content.

[0059] Optionally, the excess text in the current line of string is added to the next line of string, including: if the excess text in the current line of string is the remaining content of the target word, the target word is truncated, and the remaining content of the truncated target word is added to the next line of string.

[0060] The target word may be a long word that cannot be fully displayed in the current line. It should be noted that by truncating and wrapping the long word, the neatness of the text layout can be ensured.

[0061] The technical solution of the embodiment of the present invention can adjust the font size and / or the text line break of the text content so that the text content does not exceed the invoice target area, thereby improving the display effect of the invoice image.

[0062] Embodiment 3

[0063] Figure 3 A flowchart of an image generation method provided for Embodiment 3 of the present invention, the method of this embodiment can be combined with the various optional schemes in the image generation method provided in the above embodiments. The image generation method provided in this embodiment is further optimized. Optionally, the text content after the text format is adjusted is filled into the invoice target area to obtain the target invoice image, including: determining the initial coordinates for drawing the text content; taking the initial coordinates for drawing the text content as the starting point, drawing the text content after the text format is adjusted line by line into the invoice target area to obtain the target invoice image.

[0064] like Figure 3 As shown, the method includes:

[0065] S310: Acquire an invoice target area to be filled with text, and determine the width and height of the invoice target area.

[0066] S320, obtaining text content to be filled into the target area of ​​the invoice, and determining the width and height of the text content.

[0067] S330: Adjust the text format based on the width and height of the invoice target area and the width and height of the text content.

[0068] S340. When the width of the text content after the text format is adjusted is not greater than the width of the invoice target area, and the height of the text content after the text format is adjusted is not greater than the height of the invoice target area, determine the initial coordinates for drawing the text content, and use the initial coordinates for drawing the text content as a starting point to draw the text content after the text format is adjusted line by line to the invoice target area to obtain a target invoice image.

[0069] In the embodiment of the present invention, the initial coordinates for drawing the text content may be the upper left corner position or other vertex positions of the invoice target area, which is not specifically limited here.

[0070] Exemplarily, the initial coordinates for drawing the text content can be (startX, startY); the initial x coordinate can be set: x=startX, and the initial y coordinate can be set: y=startY. After each line is drawn, the y coordinate is incremented: y=y+lineHeight to ensure that the next line of text is displayed below the current line of text, where lineHeight represents the height of a single line of text. Further, the imagettftext or drawText function is used to draw the text content line by line, and each line of text content in the line list is drawn sequentially into the invoice target area. During the line-by-line drawing process, the starting drawing position of each line can be determined by x and y. After all lines of text are drawn, the target invoice image can be saved to a specified path or displayed on the screen.

[0071] The technical solution of the embodiment of the present invention determines the initial coordinates for drawing the text content; takes the initial coordinates for drawing the text content as the starting point, and draws the text content with the text format adjusted line by line to the invoice target area, thereby achieving accurate typesetting of the text content and improving the display effect of the invoice image.
