CanvasDrawText( canvas, text, x, y, font, fontSize, color, bold, italic, hAlign, vAlign )
Draws text on a canvas.
- «canvas» is a canvas obtained from calling the
Canvas()function, or a canvas context obtained by calling theCanvasContext()function. - «text» is the text to draw.
- «x», «y»: The location where the text will display.
- «font»: (optional) the textual font name, such as
'Arial', 'Comic Sans MS', 'Times New Roman'. - «coor»: (Optional) Either a textual color name or a color integer. (See CellFill for an enumeration of textual color names). A color integer encodes red, green, blue and optionally alpha as
0x01000000 * alpha + 0x00010000 * red + 0x0000100 * green + 0x000001 * blue. Defaults to 'Black'. - «bold», «italic»: (Optional) When true, the text is draw in bold or italic font respectively.
- «hAlign»: (Optional) Horizontal alignment relative to «x», either
'Left', 'Center' or 'Right'. Default is'Left'. - «vAlign»: (Optional) Vertical alignment relative to «y», either
'Top', 'Middle' or 'Bottom'. Default is'Top'.
When drawn to a context where the coordinate frame as been scaled, the text (and the interpretation of «fontSize» is scaled as well. When the x- and y-axes are scaled differently, the text will be squashed or stretched. When one logical unit along x corresponds to two device pixels, then text will be twice as wide as it would be if rendered at the same «fontSize» without scaling.
