Importing Photoshop files
When you open or import a Photoshop file that contains layers, Canvas imports the file’s layers as
separate objects and stacks them in the document on the current layer.
Layers that have transparency are imported with visibility masks. Canvas creates an alpha channel
and a channel mask for a Photoshop layer mask. Canvas also imports alpha channels.
Using Tag Image File format (TIFF)
Tag Image File Format is a high resolution, raster image format. Canvas supports both RGB and CMYK
TIFFs. Although TIFF is a common format, many TIFF variations exist. Different resolutions, color
systems, previews, and compression schemes make the format flexible, but can cause compatibility
problems.
Canvas can read tiled TIFFs. A tiled TIFF is an image divided into smaller, rectangular
portions.
When you save TIFF files, you have various options in the Export TIFF dialog box.
