Group 3, Group 4, and Huffman are available to compress images
that are in black-and-white mode.
RLE and LZW compression can be applied to all image modes, except
CMYK Color.
To save an image without compression (the most compatible format),
select None.
Using text files
Text is a standard format for files containing only ASCII (American
Standard Code for Information Interchange) encoded characters.
Text format is available on nearly every computer platform; it’s the
“plain vanilla” format, the lowest common denominator for words
and numbers. Text files don’t include proprietary or application-spe-
cific character or formatting codes. Some punctuation marks, sym-
bols, and all accented letters are non-ASCII characters that display
incorrectly when used in text files. Still, ASCII text can be used to
transfer text among a variety of applications, including text editors,
word processors, and databases.
When you open a text file, Canvas creates one text object containing
the file’s contents, and assigns the default font and text formatting
attributes to it. If the file contains more text than can fit in the Canvas
workspace, Canvas truncates the text object and displays an overflow
indicator. You can then flow the truncated text into other columns.
Using Object Linking and Embedding (Windows)
In Windows, Object Linking and Embedding (OLE) lets you easily
exchange graphics among programs. Because Canvas provides full
OLE support, objects you exchange retain their full functionality and
are editable with all the tools of the original application.
Windows programs provide various levels of OLE support. In OLE
parlance, Canvas is a fully capable object and container application.
Briefly, this means Canvas can transfer objects to and from other pro-
grams through OLE.
In the world of OLE, objects created in Canvas are identified as
“Canvas Drawing” objects. If you use the Insert Object command in
another application, you should be able to select “Canvas Drawing”
as a type of object to insert.
