Importing and Exporting 487

Also export Retina (192dpi) bitmap
With this option checked you can simultaneously export a 192 dpi high definition Retina
image. This saves you exporting twice if you have a need to provide a 96dpi as well as a
192dpi resolution image for Retina devices. For JPEG and PNG the operation is only
valid when you have the 96dpi option selected.

See High resolution images (on page 352) for more info on Retina images.

Options tab
With this tab you can alter JPEG compression and turn on progressive/interlacing for the
GIF and PNG options if required.

JPEG Quality: (JPEG only) A low setting will result in a small file with a loss in quality
whereas a high value will give only slight file size reductions, but high quality. Note that a
setting of 100% will still compress the file. A setting of 85% gives good compression
without causing a noticeable loss in quality for most uses.

Interlaced: (GIF and PNG only) This is like a JPEG. In the browser the picture first
appears as a low resolution image. As more of the file loads, the resolution increases.

Transparent: (GIF and PNG only) This makes any areas not covered by the selected
objects transparent. Selecting this option automatically makes one entry in the palette
transparent.
Export each layer to a file of its own: (GIF and PNG only) Selecting this option when
exporting a design that contains multiple layers results in a separate file being exported
for each layer. The names of each layer (as set in the Page & Layer Gallery) are used to
name the exported files.
Browser Preview tab

Using the A and B preview boxes in the EXPORT dialog box (shown above), you can
select the best compromise of file size and quality for web graphics. However the best
test is checking how the graphic looks in a web browser. This tab provides a number of
options for that preview. Click the BROWSER PREVIEW button to launch your web browser
and preview the graphics before exporting.
