• If you choose Keep Scale, the graphic will be cropped to the scales shown in

the width and height boxes and the picture reduced in size accordingly.

• If you choose Keep image size, the graphic will be cropped and then enlarged

to the original image size.

Take care with these operations: in the Crop dialog the width and height are treated

as totally independent values. Changing one without the other can result in

significant distortion of the image; this might not be what you want. (The Position and

Size dialog on the context menu has an option for keeping the width:height ratio

fixed while changing one of the two dimensions.) Changing values in one area (Scale

or Image Size) will show up correspondingly in the other area.

Caution

Any changes made in the Crop dialog change only the view of the

picture. The original picture is not changed. If you want to export a

cropped graphic, you must do it through File > Export. If you use the

option Save as Picture from the context menu, the changes are not

exported.

The graphic filter toolbar

Click the Filter icon to open the Filter toolbar. Draw offers eleven filter effects.

Filters work on the current view of an object and they can be combined. Filters

always apply to the entire graphic; it is not possible to use filters to edit only a part of

the object.

Invert reverses (inverts) the colors of an image so that it appears as a

color negative of the image.

Smooth reduces the contrast between neighboring pixels and produces a

slight lack of sharpness. If you use the filter several times in a row, the

effect will be strengthened.
