Abstract
A method for selecting a desired color from a screen display using a color selection tool that may appear as an eyedropper. Rather than independently choosing pixels or a matrix of pixels, the user blends a color by selecting pixels using a mouse cursor. In response, the color of each selected pixel is incrementally blended into the current color at a constant rate. That is, each selected pixel is blended with the current color according to a constant blending factor. In this manner, the current color changes at a constant rate with the contribution of each successive pixel. This approach allows the user to gradually blend colors from the screen display, much as a painter would gradually mix colors on a palette.
Claims24
A method of selecting a color from a screen display, comprising:
- receiving a selection of a screen pixel on the screen display;
- determining a first color value corresponding to a color of the screen pixel;
- determining a second color value corresponding to an active color setting;
- blending the first color value with the second color value to generate a third color value, wherein the first color value and the second color value are blended based on a constant blending factor;
- and
- storing the third color value as the active color setting.
A computer-readable storage medium storing instructions that when executed by a processor cause the processor to select a color from a screen display by performing the steps of:
- receiving a selection of a screen pixel on the screen display;
- determining a first color value corresponding to a color of the screen pixel;
- determining a second color value corresponding to an active color setting;
- blending the first color value with the second color value to generate a third color value, wherein the first color value and the second color value are blended based on a constant blending factor;
- and
- storing the third color value as the active color setting.
A method for blending colors from colors of one or more pixels on a display screen, comprising:
- invoking a color selection tool provided by a computer aided design (CAD) application, wherein the color selection tool is configured to:
- receive a selection of a screen pixel on the screen display;
- determine a first color value corresponding to a color of the screen pixel;
- determine a second color value corresponding to an active color setting;
- blend the first color value with the second color value to generate a third color value, wherein the first color value and the second color value are blended based on a constant blending factor;
- and
- store the third color as the active color setting.
