A brief talk on several text output functions of pdflib Chinese output (iii.) pdflib

1. Pdf_show

void Pdf_show (PDF *p, const char *text)

void Pdf_show2 (PDF *p, const char *text, int len)

Outputs text in the current coordinates with the current font and font size.

Pdf_show will assume that the string ends with a null character (null), and if the string might contain a null character (such as a multibyte string), use Pdf_show2.

2. Pdf_show_xy

void Pdf_show_xy (PDF *p, const char *text, double x, double y)

void Pdf_show_xy2 (PDF *p, const char *text, int len, double x, double y)

Outputs text in the given coordinates with the current font and font size.

Pdf_show_xy will assume that the string ends with a null character (null), and if the string might contain a null character (such as a multibyte string), use Pdf_show_xy2.

3. Pdf_continue_text

void Pdf_continue_text (PDF *p, const char *text)

void Pdf_continue_text2 (PDF *p, const char *text, int len)

Output text with the current font and font size on the next line.

Pdf_continue_xy will assume that the string ends with a null character (null), and if the string might contain a null character (such as a multibyte string), use Pdf_continue_xy2.

4. Pdf_fit_textline

void Pdf_fit_textline (pdf*p, const char *text, int len, double x, double y, const char *optlist)

Outputs a line of text from the selected item in the given coordinate.

If the string ends with a null character (null) and Len is 0, the number of bytes is given.

5. Pdf_fit_textflow

int Pdf_create_textflow (PDF *p, const char *text, int len, const char *optlist)

Creates a text stream object and prepares the text for formatting the following text.

If the string ends with a null character (null) and Len is 0, the number of bytes is given.

const char *pdf_fit_textflow (PDF *p, int textflow, double llx, double lly, double Urx, double ury, const char *optlist)

Outputs the text to the appropriate rectangular block.

Lly, Llx, URY, Urx, respectively, are the vertical and horizontal coordinates of the lower-left corner of the rectangular block and the upper-right corner.

void Pdf_delete_textflow (PDF *p, int textflow)

Deletes text stream objects and related data structures.
