Every image is contained by a shape. When you insert, or copy and paste, or drag and drop an image (or PDF) into a document you can either add it to an existing shape, or otherwise a rectangle shape (with no line stroke or color fill) will be created to hold it. Images added outside existing shapes are scaled to fit comfortably within the currently set page size. PDFs added outside existing shapes are scaled at full size. Images and PDFs can be sized and fitted within their containing shape.
•
To add an image to an existing shape (or shapes) select the shape(s) before inserting or pasting the image. An image file in Finder can be dragged and dropped on a shape without any preselection - just drop it when the shape becomes highlighted.
•
Any shape can be used to contain an image, including shapes from the Shape Library and those drawn with the drawing tools. Each shape can hold a maximum of one image at a time.
•
How an image fits in a shape is controlled by the Image Inspector Fit setting. Images and PDFs are added to shapes with a default Fit setting of “Fit - No Stretch”, which enables image repositioning/resizing by selecting and moving/resizing the containing shape. The Fit - No Stretch setting scales an image proportionally to fit entirely within the bounding box of its containing shape, such that it always just fits within (and fills) the smallest relative dimension (width or height) as the shape is resized.

iStudio Publisher provides fully adjustable "shaped cropping" of images, within any shape, including shapes from the Shape Library and those drawn with the various drawing tools. To enable shaped cropping, select a shape containing an image and then go to the Image Inspector and set options Fit: Manual and Align: Manual. You will now be able to set the size and position of the image with complete freedom behind the "viewing window" formed by its containing shape. Only the image area that lies within the shape will be visible. Adjust the size of the cropping shape with the Pointer Tool and its shape contour with the Reshaping Tool, as required.
IMPORTANT: Avoid setting Fit: Manual on the Image Inspector and then scaling down an image so that its containing shape remains much larger than the image. This can become inconvenient if the containing shape covers other document content and prevents its selection. We recommend only setting Fit: Manual when you want to crop an image.

To work with an image at a particular DPI (dots per inch) resolution choose the DPI value on the Image Inspector “Use DPI” pop-up list. The Scale settings on the Image Inspector will change to reflect the newly set Use DPI value, enabling the image to be managed and resized in this context. Generally, use 300 DPI for images in documents that will be printed out, or 72 DPI for documents that will only be viewed electronically, on a screen.
IMPORTANT: You should keep the Scale settings at or below 100% for the image resolution to remain at or above the Use DPI value. Scale settings above 100% are displayed in a red warning color to alert that the image has been stretched and may appear pixelated when printed or displayed.
