Abstract

A system for providing fonts, an apparatus for providing Metafont fonts, and a method for controlling the apparatus are disclosed. The disclosed apparatus, which connects to a device to provide Metafont fonts, includes: a communication module configured to receive a first font request from the device for the font engine, where the first font request includes at least one font style parameter and the ID information of a Metafont font file; and an operating module configured to determine whether or not a font file having ID information identical to the ID information of the font file included in the first font request exists in a first external memory, and if a font file having identical ID information exists, determine whether or not the font converted from the font file having identical ID information is saved in a second external memory.

First claim

What is claimed is:

1. An apparatus configured to connect, via plug-in or add-on, to a font providing device that does not support Metafont fonts, and configured to provide the font providing device with a Metafont font in which a font style is set according to a user's request, the apparatus comprising:
a communication module configured to receive a first font request from the font providing device, wherein the first font request is a font request requesting the Metafont font from the font providing device and includes at least one font style parameter and ID information of a Metafont font file;
an operating module configured to, when a font file having ID information identical to the ID information of the Metafont font file included in the first font request exists in a first external memory, determine whether or not an outline font A is saved in a second external memory, wherein the outline font A is an outline font that has previously been converted by using a font style parameter identical to the at least one font style parameter; and
a converter module configured to convert a font file to an outline font using a font style parameter,
wherein,
when the outline font A is saved in the second external memory, the communication module transmits save information of the outline font A to the font providing device,
when the outline font A is not saved in the second external memory, the converter module converts the font file having the identical ID information and existed in the first external memory to the outline font A by using the at least one font style parameter and saves the converted outline font A in the second external memory, and the communication module transmits the save information of the converted outline font A to the font providing device, and
the font providing device reads the outline font A from the second external memory based on the save information of the converted outline font A and provides the outline font A to the user.

2. The apparatus according to claim 1 , further comprising:
a search module configured to search for ID information of at least one pre-existing Metafont font file in the first external memory and save the ID information of the at least one pre-existing Metafont font file as a list,
wherein the operating module determines whether or not the font file having the identical ID information exists in the first external memory by using the list provided from the search module.

3. The apparatus according to claim 1 , wherein when the font file having identical ID information does not exist in the first external memory, the communication module transmits information notifying that the font file having identical ID information does not exist to the font providing device.

4. A method for controlling an apparatus connecting, via plug-in or add-on, to a font providing device that does not support Metafont fonts to provide the font providing device with a Metafont font in which a font style is set according to an user's request, the method comprising:
receiving a first font request from the font providing device, wherein the first font request is a font request requesting the Metafont font from the font providing device and includes at least one font style parameter and ID information of a Metafont font file;
determining whether or not a font file having ID information identical to the ID information of the Metafont font file included in the first font request exists in a first external memory;
when the font file having identical ID information exists in the first external memory, determining whether or not an outline font A is saved in a second external memory, wherein the outline font A is an outline font that has previously been converted by using a font style parameter identical to the at least one font style parameter;
when the outline font A is saved in the second external memory, transmitting save information of the outline font A to the font providing device; and
when the outline font A is not saved in the second external memory, converting the font file having identical ID information and existed in the first external memory to the outline font A by using the at least one font style parameter included in the first font request, transmitting the converted font A to the second external memory, and transmitting the save information of the converted font A to the font providing device,
wherein the font providing device reads the outline font A from the second external memory based on the save information of the converted outline font A and provides the outline font A to the user.

5. A system for providing fonts, the system comprising:
a first device including a font engine that does not support Metafont fonts;
a second device configured to connect, via plug-in or add-on, to the first device and provide a user of the first device with a Metafont font in which a font style is set according to the user's request;
a first memory device configured to save at least one font file; and
a second memory device configured to save at least one outline font,
wherein the first device receives a font request from a user and transmits the font request to the second device, the font request is one of a first font request and a second font request, the first font request is a font request requesting Metafont font and includes at least one font style parameter and ID information of a Metafont font file, and the second font request is a font request requesting a font being different from the Metafont font,
wherein the second device
determines whether the font request is the first font request or the second font request,
when the font request is the first font request, determines whether or not a file having ID information identical to the ID information of the Metafont file included in the first font request exists in the first memory device,
when the font file having identical ID information exists in the first memory device, determines whether or not an outline font A corresponding to the font file is saved in the second memory device, and
when the outline font A is saved in the second memory device, transmits save information of the outline font A to the first device, and
when the outline font A is not saved in the second memory device, converts the font file having the identical ID information and existed in the first external memory to the outline font A by using the at least one font style parameter and saves the converted outline font A in the second external memory, and transmits the save information of the converted outline font A to the first device, and

wherein the first device reads the outline font A from the second memory device based on the save information of the outline font A and provides the outline font A to the user.

6. The system for providing fonts according to claim 5 , wherein
the second device transmits, when the font request is the second font request, information notifying that the font request is the second font request to the first device, and
the first device reads a font corresponding to the second font request from the second memory device based on the information and provides the font to the user.

7. The system for providing fonts according to claim 5 , wherein
the second device transmits, when the font file having identical ID information does not exist in the first memory device, information notifying that a font file having identical ID information does not exist to the first device, and
the first device reads a preset default font from the second memory device based on the information and provides the default font to the user.
