Cropping pictures
Impress provides two ways to crop a picture: interactively or using a
dialog box. The interactive method is easier to use, but the dialog box
provides more precise control. You can use both methods: first
cropping interactively, then using the dialog box to fine tune the result.
To crop a selected picture interactively, click the Crop icon on the
Picture toolbar (Figure 61). A set of crop marks appears around the
picture (see Figure 64).
Figure 64: Interactive crop marks
When you place the cursor over any of the crop marks, the cursor
changes shape. Drag the mark to crop the picture. Click outside the
picture to deactivate cropping mode.
Press the Shift button while working on the crop marks to produce the
following effects:
• For a corner mark, the two sides of the picture forming the corner
are cropped proportionally with the picture anchored to the
opposite corner mark.
• For a side mark, both dimensions are changed proportionally with
the image anchored to the opposite side mark.
The interactive crop mode operates in Keep Scale mode (see below).
To crop using the dialog box, right-click a selected picture and choose
Crop Picture (or choose Format > Crop Picture from the menu bar).
The Crop dialog box (Figure 65) has the following options:
• Keep scale / Keep image size buttons: when Keep scale is
selected (default), cropping the image does not alter the scale of
the picture. When Keep image size is selected, cropping produces
enlargement (for positive cropping values), shrinking (for
negative cropping values), or distortion of the image so that the
image size remains constant.
