A method, system, and computer-readable storage medium are disclosed for boundary-aligned anti-aliasing. In one embodiment, artwork input comprising a first set of one or more graphical elements and a second set of one or more graphical elements may be received. The first set may comprise at least one horizontal or vertical line segment. Each graphical element in the first set of one or more graphical elements may be automatically aligned to pixel boundaries based on a pixel resolution of a target imaging device. An anti-aliasing function may be applied to generate a selectively anti-aliased artwork based on the artwork input. Applying the anti-aliasing function may comprise applying anti-aliasing effects to the second set of one or more graphical elements and not to the first set of one or more graphical elements. The selectively anti-aliased artwork may be displayed on the target imaging device.

Pixel-aligned drawing to avoid anti-aliasing

A touchscreen device may be configured to facilitate drawing lines, circles, and shapes through use of a guide device placed on the touchscreen. The touchscreen device may detect the position and orientation of the guide device, for example, by determining an axis of the guide device based on a set of locations at which the guide device triggered contact signals on the touchscreen. Based on the detected position and orientation of the guide device on its touchscreen, the touchscreen device may display one or more lines or shapes on the touchscreen. If a user traces a portion of such a displayed line or shape, the touchscreen device may display the traced portion. A button on the guide device may be configured to cause the touchscreen device to sequentially display available lines and shapes. The user may also configure the button to display one or more user-generated shapes.

Methods and apparatus are provided for dynamically halftoning image data, substantially in real-time. Halftone threshold values are calculated and stored in memory, and halftone output values are calculated for the portions of the image data that will be displayed on a display device. Halftone screen parameters may be modified, and new halftone screen threshold values may be calculated for any affected halftone screens. For unaffected halftone screens, the previously stored threshold values may be retrieved from memory. In addition, the portion of the image to be displayed may be modified, and the halftone output values of the new portion may be calculated and then displayed.

A method and interface for displaying and configuring color management settings for printing devices is provided. The user interface provides a graphical representation of the color workflow as it takes place on the printing device. From the user interface, the user configures various page elements and color models; such as RGB, CMYK, Spot Color and Black using pull down menus of options and other interface elements. Available options include color space transformations, color corrections and printing methods. Interface mapping changes in real time to reflect the user's modifications to the color management settings at the various points of the workflow. In a network environment providing bi-directional communication between workstations and network peripherals, the color management tool queries the printing device and dynamically builds the user interface according to the unique characteristics and capabilities of the printing device; if bi-directional communication is not available, the interface is built from generic options. Thumbnail images, also updated in real time, provide previews of the output. The invention may also take the form of a computer program product on a computer-usable storage medium having computer-usable program code means embodied in the medium.
