Hi,
In order to be able to change the foreground color of a picture in Planet Press design it has to be monochrome bitmapped image(.bmp or .png)
Here is some info straight from our Help file.
Transparent: If the image is a monochrome bitmapped image, select to make the background color of that image transparent. This makes the white pixels of the image transparent.
Duotone: Select to create a duotone by replacing the foreground color in the bitmapped image with a color. Click Color to select the color using the Color Picker. The Color box displays the current duotone color.
Note that any changes to the foreground color are internal to the picture object and do not have any effect on the image resource itself.
Color: Click to select the foreground color for the duotone using the Color Picker. The color you select replaces the current foreground color in the bitmapped image.
Color box: View the current duotone color. This is the color that replaces the foreground color in the bitmapped image.
You can access that menu by simple double clicking on the image ressource and then going into settings.
Let me know if this answers your questions.
Best Regards,
Marc
