Tools - Make Image

The Tools - Make Image command (keyboard shortcut F6 key) is used to create images from components. It operates slightly differently depending on whether the component is a print Layout or other component. Layouts are different than ordinary component windows because a layout is directly associated with a specific paper size as printed on a specific printer. Within layouts the key question is what resolution (DPI) should be used for the image since the physical extent of the image is fixed by the page size and the composition in the layout.

 

On the other hand component windows other than layouts do not have any fixed extent nor are they tied to a specific paper size. Drawings, for example, have limitless extent. When an image is to be created based on a component window there are several different ways in which the extent, scale and resolution of the image can be defined.

 

When Make Image is launched from a component other than a layout, it allows a choice in the Paint dialog of different ways to output the image based on what is in the display window. When Make Image is launched from a layout, the resolution of the image is specified in DPI.

 

Controls when used from Layouts

 

Name

Choose a name to use for the new image. The default name suggested will be constructed from the component name that is displayed in the active window.

Description

Any text entered here will appear in the image's Description property in the View - Properties dialog. Use for whatever user-supplied notes may be desired.

Resolution

Choose the desired image resolution in DPI.

Page

Which page of a multipage layout to capture as an image.

(Status bar)

The status bar region at the bottom of the dialog reports the vertical and horizontal size in pixels and the overall size in megabytes of the image that will be created.

 

Use Make Image from a layout when an image must be created at a specific DPI. For example, suppose we would like to contribute an illustration to a publication and we have been asked by the publication's art department to provide an image at 600 DPI. Suppose the illustration desired is an image of a map component we have created. We can create a layout using the map and then use Make Image from the layout with a Resolution of 600 DPI. We then open the image and export it to whatever image format file (such as TIFF or JPEG) that is required by the publication.

 

Controls when used from other Components

 

Name

Choose a name to use for the new image. The default name suggested will be constructed from the component name that is displayed in the active window.

Description

Any text entered here will appear in the image's Description property in the View - Properties dialog. Use for whatever user-supplied notes may be desired.

Paint

Choose the image output from centered view at current scale, current window, entire component and entire component at current scale.

Size

Horizontal x vertical size of the image to be created in pixels. Enabled when the Paint selection is centered view at current scale or entire component.

(Status bar)

The status bar region at the bottom of the dialog reports the vertical and horizontal size in pixels and the overall size in megabytes of the image that will be created.

 

Paint Options

 

centered view at current scale

Creates an image at the current scale (zoom level) that shows as much of the image as is possible at the given width and height in pixels. Increasing the size (width and height) will show more of the component in the image.

current window

Makes a snapshot of the current window at screen resolution (72 or 96 DPI, typically). The image will reproduce what is seen in the window. This option is very fast.

entire component

Creates image at the given width and height in pixels that shows the entire component. Increasing the size of the image by increasing the width and height will still show the entire component, but with greater resolution.

entire component at current scale

Creates an image of sufficient height and width to show the component at the current scale (zoom level).

 

Components like drawings have limitless extent. The "entire component" in this context means the size of the minimum enclosing rectangle that encloses all objects in the drawing. When entire component is chosen as the Paint option, Manifold will fit the rendering of the drawing to the maximum possible size given the pixel size of the image in width and height.

 

Use Make Image from components other than layouts when an image must be created to a particular scale or of a particular width and height in pixels. For example, suppose we would like to create an image from a highly detailed map that we will use as a wallpaper background image on our Windows desktop. Let's say we have a cool new flat panel monitor with 1900 by 1200 resolution. We can open the map, zoom to about the resolution we would like and then use Make Image with the centered view at current scale option with width and height set to 1900 by 1200 pixels. We then open the image and export it to the file format we want to use.

 

Note that to achieve a more detailed, higher resolution view we must use entire component with a larger number of pixels. Increasing the number of pixels used with the centered view at current scale option does not result in more detail, because the level of resolution is set by whatever scale is being viewed (the "current scale").
