Defining file types
One of the most confusing things about working with paint objects is
the great variety of file types. The most common image file types are
GIF, JPEG, TIFF, PICT, and BMP, as well as EPS (which can con-
tain both paint and vector objects).
GIF and JPEG: Compressed formats that are used heavily on
the Internet. The compression levels allow these images to achieve
small file sizes and as a result they download quickly over the Inter-
net. However, file size compression comes at the expense of image
and color integrity.
TIFF, PICT, BMP and EPS: These files have a lower level or no
amount of compression. Information for every pixel is recorded, and
this can result in large files. Because of the higher resolution and
detail needed for printing, these formats are often used for projects
that will eventually be printed commercially.
There are a number of ways in Canvas to place an image file in your
document. In addition to the Place command in the File menu, there
is also the Acquire command in the Image menu.
Finally, you can directly scan into Canvas using any TWAIN com-
patible scanner, or a scanner with a Photoshop compatible acquire
module.
Creating a duotone vignette
In this lesson, youll learn how to create a duotone and make a
vignette from a photograph. A duotone is a grayscale image usually
printed with black and an additional color. A vignette is a non-rectan-
gular image, usually with a soft edge.
You will also crop the photograph, change the image mode, and
apply a vector mask to complete the vignette effect.
To begin, open the file named Image1.cnv in the Tutorial folder.
