TIFF Compression<br />

Chapter 2: Documents and Setup<br />

Various compression options are available, depending on the mode of the image you are saving.<br />

Compression None: Saves an image without compression (the most compatible<br />

format).<br />

Group 3 and Group 4: Are available to compress images that are<br />

in black-and-white mode.<br />

LZW: Can be applied to all image modes, except CMYK Color.<br />

Deflate: Applies a lossless compression to the image.<br />

JPEG: Applies a JPEG lossy compression to the image.<br />

Adobe Deflate: Reduces image size but does not affect image<br />

quality since it is a lossless compression.<br />

Resolution Indicates the default resolution. Enter a value in the Horizontal and<br />

Vertical field if necessary.<br />

To export as TIFF with transparency:<br />

<strong>Canvas</strong> supports transparency in TIFF images upon import and export. In <strong>Canvas</strong>, you can create<br />

transparency in images using either a clipping path, channel mask, or visibility mask.<br />

1. Create the object and apply one of the aforementioned transparency techniques.<br />

If you are using vector objects, the vector objects will be rendered before exporting.<br />

2. Choose File | Save As or Image | Export.<br />

Saving as SVG<br />

Scalable Vector Graphics (SVG) is a vector graphics language written in Extensible Markup Language<br />

(XML). This format enables two-dimensional images to be displayed in XML pages on the Web. With<br />

the SVG format, graphics are coded directly into an XML document.<br />

In contrast to JPEG and GIF images on the Web, which are bitmapped and always remain a specified<br />

size, SVG images are scalable to the size of the viewing window and will adjust in size and resolution<br />

according to the window in which it is displayed.<br />
