Rendering with the Camera tool You can use the Camera tool to create a paint object from any area in a document. The Camera tool renders the area you select. You can set the resolution, color mode, and other options for the rendered image. The Camera tool is located in the Effects toolbar in the Toolbox. Using the Camera tool is like taking a snapshot of the screen. You simply use the Camera tool to select a rectangular area for rendering. Render Image settings When you use the Render command, you can specify image mode, resolution, and other settings in the Render Image dialog box. Dimensions. Displays the width and height of the paint object Canvas will create. A   Choose the measurement for the Width and Height values in the Dimension area; inches, centimeters (cm), points, or pi- cas. Mode. Choose the color mode for the resulting image: Black & White, Grayscale, Indexed Color, RGB Color, CMYK Col- or, or LAB Color. Width and Height. Enter the pixel dimensions for the paint object. When you change a value, Canvas adjusts the oth- ers to maintain the size and proportions of the original objects. Res. Choose pixels per inch or pixels per centimeter in the pop-up menu. The value shown after “Size” is the amount of data in the image, based on the mode, resolu- tion, and dimensions. Anti-Alias. Blurs edges while rendering to make the edges of text characters and vector objects appear smoother in the resulting image. Choose Fine, Medium, or Coarse in the pop-up menu. Coarse uses 16 shades for anti-aliasing and is the fastest option. Medium uses 64 shades for anti-aliasing. Fine uses 256 shades for anti- aliasing. Fine produces the softest edges and is the slow- est option. Mask. Select this option if you want the resulting paint object to have a visibility mask or a channel mask. Then choose the type of mask. Transparency creates a chan- nel mask. The channel mask is based on the silhouette of the rendered objects. In other words, if there are spaces between the objects, the chan- nel mask will create transpar- ent spaces. Visibility creates a visibility mask in the paint object. The result is a clear background in areas not covered by objects. If you do not select Mask, areas not filled by rendered objects within the paint object’s bounding rectangle will be white and opaque. If you select Mask and either Transparency or Visibility, areas that are not filled by ren- dered objects will be transpar- ent. A
