You can apply a pattern as a fill for any graphic. In EazyDraw this is an additional fill effect that is used independently or in conjunction with another fill. The pattern fill is applied over (in front of) Fill or Gradient Fill and in back of Vector Hatch The controls at the top of the Patterns Palette allow you to the visibility of underlying color(s).

In order to be used as an overlay with other coloring, the individual pixel colors need to fully support transparency () Opacity on the color palette), and some of the pixels will need to be at least partially transparent to allow the coloring in back of the pattern to be visible.

Images imported from other systems or certain file formats may not support transparency. If not, the individual pixel colors will need to be converted to support the alpha channel or opacity. This can be done with the Transparency check box near the top of the palette.

The Fill check box is used to turn the pattern on for the selected graphic(s). Check the box to use the pattern as the one and only fill effect for a graphic.

The Overlay check box is used to apply the pattern on top of other color fill effects. The individual pattern colors need to support transparency for this effect to be visible.

The Transparency check box can be used as an indicator to verify that the pixels of a bit map can support opacity as a color variable. The check box can also be used to explicitly convert the colors of all pixels to include or exclude the alpha channel (opacity value) byte. If the conversion is not possible the action will simply beep and no conversion will take place.

Transparent Conversion Color: When converting from an opaque image to a transparency supporting image, the background color of the drawing is used as the "transparent color". This will match the appearance on the drawing. This mechanism may be used as a tool to set a desired color to "clear color" for a pattern; this may be quicker than painting individual pixels.

EazyDraw Help Pages example

The example to the right demonstrates use of transparency and the overlay attributes. The pattern at the top is just transparent bricks. The next down has the transparent bricks overlaying a solid fill color. The bottom example has the transparent bricks overlaying a gradient fill.

Transparent pixels are discernible in the close-up view. You can notice that the background horizontal lines (which are by-the-way generated as a pattern) are visible through the pixel rectangle. You may want to apply a white color to a pixel to learn the recognize the difference. The difference is subtle by necessity since a specific color really can't be used as a visual clue.

If a graphic that contains a pattern is flipped or rotated, the pattern is flipped or rotated too. This is a convenient way to expand the capabilities of the pattern panel in designing patterns. It is usually a good idea when designing patterns to have them attached to a graphic. This provides the transform capability mentioned here and provides Undo capability.
