Pictures (PNG, JPEG, WebP, PSD)

To put a drawing in a document, an e-mail or a web page, save it as a picture with File › Export › Export…. Choose PNG, JPEG, WebP or Photoshop documents (PSD) as the file's type; the options then let you set how big the picture is.

Size

• The drawing's size, at the resolution: the picture is as many pixels as the drawing is big at the resolution you give (300 DPI makes a 100 mm drawing 1,181 pixels across). Printed at that resolution, it comes out the drawing's own size.
• A width or a height: the picture is that many pixels across (or up), the other side in proportion.
• A width and height: the picture is exactly that size, with the drawing fitted inside and centred.

The dialog shows the picture's size in pixels as you change these. The margin is the space round the drawing (5 mm unless you give another). A picture is at most 30,000 pixels a side (WebP 16,383), and 300 million pixels in all. PNG, JPEG and PSD files record the resolution, so programs that print or place them know how big they should be.

Picture

• Background: white or black; PNG, WebP and PSD pictures can also be transparent round the drawing.
• Thinnest line: lines are drawn at least this many pixels wide, so the thinnest still show in a small picture.
• Quality (JPEG and WebP): higher is sharper and larger. 90 suits drawings; PNG is always exact.
• Lossless (WebP): every pixel kept exactly, like PNG, but usually smaller.

Photoshop documents (PSD)

A PSD keeps the drawing's layers apart, to work on in Photoshop or another program that opens PSD files:

• Each of the drawing's layers that has something on it is a layer of the document, with the layer's name, hidden if the layer is hidden. Anything on no layer is on a layer called Drawing, at the bottom.
• The background (white or black) is a layer of its own, Background, under the rest; with a transparent background there is none.
• The document also keeps the picture as it looks, all its layers together, so programs that don't read layers show it as it is.

PSD files are 8-bit RGB, compressed without loss. ParametrIQ also reads them: the Raster Image Tool places a PSD's picture as it looks, and the Pack Designer keeps artwork in them.

Magnifiers are drawn as on screen: what each callout shows is cut to the callout.

The drawing is in its print colours, and its text is drawn as outlines, so it looks the same on any computer.
