Adaptive and dynamic text filtering

A device, comprising:

• a sensor to determine an external state of the device;
• a processor to dynamically filter text that is displayed based on the external state of the device and the processor configured to:
• retrieve outline points for one or more characters;
• generate an outline from the outline points;
• and
• rasterize the outline into a bitmapped image;
• and
• a display screen to display the dynamically filtered text, wherein the processor further dynamically filters text such that the text is maintained at a constant orientation on the display screen relative to a fixed point external to the device after the device transitions from a first physical orientation to a second physical orientation wherein the processor, when the processor dynamically filters text based on the external state of the device, is configured to:
• filter the bitmapped image based on the external state of the device after changing from the first to the second physical orientation;
• and
• generate a glyph from the filtered bitmapped image, the glyph being displayed as text on the display screen of the device.

A method, comprising:

• receiving an indication of a first orientation of a device from an orientation sensor;
• filtering a character that is displayed as text on a display screen of the device according to the first orientation wherein the character is generated from an outline specified by outline points;
• dynamically re-filtering the character to maintain the orientation of the text on the display screen relative to a fixed point that is external to the device during a transition from the first device orientation to a second device orientation and wherein the first orientation is one of a landscape orientation and a portrait orientation and the second orientation is the other one of the landscape orientation and the portrait orientation and wherein filtering a character according to the landscape orientation comprises:
• dilating the outline after changing to the landscape orientation;
• rasterizing the outline into a bitmapped image;
• filtering the bitmapped image;
• and
• generating a glyph from the filtered bitmapped image, the glyph being displayed as text on the display screen of the device.

An article of manufacture comprising a computer-readable non-transitory storage medium having content stored thereon to provide instructions to result in an electronic device performing operations including:

• retrieving outline points for one or more characters;
• generating an outline from the outline points and rasterizing the outline into a bitmapped image;
• receiving an indication of an external state of a device;
• and
• dynamically filtering text that is displayed on a display screen of the device based on the external state of the device such that the text is maintained at a constant orientation on the display screen relative to a fixed point external to the device after the device transitions from a first physical orientation to a second physical orientation and wherein the dynamically filtering operation includes:
• dilating the outline based on the external state of the device after a change to the second physical orientation;
• smoothing the bitmapped image based on the external state of the device;
• and
• generating a glyph from the filtered bitmapped image that is displayed as text on the display screen of the device.
