Abstract

A computer implemented method for preparing font information related to textual content of a received document includes determining a font data complying a font format relating to a textual content of the received document file. The font format is compared to a predetermined common font data format and the font format is converted to the predetermined common font data format if the comparison indicates a mismatch of the compared font data formats. A font file in the predetermined common font data format is created from the converted font data and also at least one web font file is created from the created font file. Finally, at least the font file complying with the predetermined common font data format and the at least one predetermined web font file are stored in a memory. A system and a non-transitory computer readable medium for storing computer program code are also described.

creating a font file in the predetermined common font data format from the converted font data,

creating at least one web font file from the created font file, and

storing at least the font file complying with the predetermined common font data format and the at least one predetermined web font file in a memory.

2. The computer implemented method of claim 1, wherein the determination of at least the font data complying a font format is performed by parsing the content of the received document file, the parsing comprising at least extracting one or more data items comprising the font data from font information embedded in the received document file.

3. The computer implemented method of claim 1, wherein the determination of at least the font data comprises detection of an indication in the received document file that an external font file is relating to the received document file, loading the external font file and parsing the content of the loaded font file, the parsing comprising at least extracting one or more data items comprising the font data from the loaded font file.

4. The computer implemented method of claim 1, the method further comprising a step of analyzing and correcting font information prior to comparison of the font format of the determined font data to a predetermined common font data format.

5. The computer implemented method of claim 4, wherein the correction comprising at least one of the following:

forming Unicode compliant character encoding of the determined font data, determining applicable font metrics data on a basis of determined font metrics data, completing the determined font data.

6. The computer implemented method of claim 1, wherein the predetermined common font data format is TrueType Font (TTF).

7. The computer implemented method of claim 6, the method further comprising a step of determining if the font data in the predetermined common font data format comprises hinting information and in response to a detection of absence of hinting information determining the hinting information to the font data in the predetermined common font data format prior to creating the at least one web font file.

8. The computer implemented method of claim 7, the method further comprising a step of adding the hinting information to the font data in the predetermined common font data format in response to the determination of the hinting information.

9. The computer implemented method of claim 7, wherein the determination of the hinting information is performed with heuristic operation.

10. The computer implemented method of claim 1, wherein the created web font files are in Embedded Open Type Format, EOT, and Web Open Font Format, WOFF, and the stored files are the following:

a web font file complying Embedded Open Type format, EOT, a web font file complying Web Open Font Format, WOFF, and font file complying TTF format.

11. A system for preparing font information related to textual content of a document comprising

one or more processors

a memory including computer program code

the memory and the computer program code configured to, with the processor, cause the system at least to perform:

receive a document file as an input,

determine at least a font data complying a font format relating to a textual content of the received document file,

compare the font format of the determined font data to a predetermined common font data format,

convert the font format of the font data to the predetermined common font data format if the comparison indicates a mismatch of the compared font data formats,

create a font file in the predetermined common font data format from the converted font data,

create at least one web font file from the created font file, and

store at least the font file complying with the predetermined common font data format and the at least one predetermined web font file in a memory.

12. The system of claim 11, wherein the system is configured to determine at least the font data complying a font format by parsing the content of the received document file, the parsing comprising at least extracting one or more data items comprising the font data from font information embedded in the received document file.

13. The system of claim 11, wherein the system is configured to determine at least the font data by detecting an indication in the received document file that an external font file is relating to the received document file, by loading the external font file and by parsing the content of the loaded font file, the parsing comprising at least extracting one or more data items comprising the font data from the loaded font file.

14. The system of claim 11, wherein the system is further configured to analyze and correct font information prior to comparison of the font format of the determined font data to a predetermined common font data format.

15. The system of claim 11, wherein the system is configured to use TrueType Font (TTF) as the predetermined common font data format.

16. The system of claim 15, the system is further configured to determine if the font data in the predetermined common font data format comprises hinting information and in response to a detection of absence of hinting information to determine the hinting information to the font data in the predetermined common font data format prior to creating the at least one web font file.

17. The system of claim 16, the system is further configured to add the hinting information to the font data in the predetermined common font data format in response to the determination of the hinting information.

18. The system of claim 16, wherein the system is configured to determine the hinting information by performing at least one heuristic operation.

19. The system of claim 11, wherein the system is configured to create web font files in format of Embedded Open Type, EOT, and Web Open Font, WOFF, and to store:
