However on the black and white Macintosh, any color other than white appears as black.

Any unset bit would make the pixel appear in the Background color. When copying a bitmap onto a Grafport, any bit that was set in the source Bitmap would make the corresponding pixel appear in the Foreground color on the Grafport. Also Foreground and Background color affect the Copybits call. Any drawing by the Pen was done in the Foreground color, any Erasing was done in the Background color. When any Grafport was created, the default settings for the Foreground and Background were Black and White respectively.Ĭolor fields were treated similar to the more often used Pen Pattern (pnPat) and Background Pattern (bkPat). By passing these constants to the procedures ForeColor and BackColor, the respective fields of the current Grafport were changed. Each color had a long integer constant associated with it. Quickdraw predefined 8 colors (Black, White, Red, Green, Blue, Cyan, Magenta and Yellow). In the original Grafport record, there were 2 fields (fgColor and bkColor) that determined the settings of the Foreground and Background color. However, the original Quickdraw had the capability to draw in color. 21,888 bytes of memory were used to display the normal 512 by 342 pixel screen (1 bit per pixel). The original Macintosh displays were in black & white. Three new Managers have been added to facilitate color the Color Manager, the Color Picker Package and the Palette Manager.Īre you ready to program with this new Color Quickdraw?īefore you answer that, did you know there was an alternative way to display color on the Mac?
