13.14.6 Scanline Orientation
Guideline: Set the appropriate scanline orientation for bitmapped image resources.
Advantage: Reduces the amount of runtime processing these image resources require.
Applies to: Bitmapped images only
How to apply it to
static images, and
dynamic images
that reference
image resources:
You set a default scanline orientation that PlanetPress Design associates with
each image resource at the time you add it to the document, in the Document
dialog box. You can also set the scanline orientation for an individual image
resource by selecting it and using the Object Inspector to edit its Scanline
orientation property.
How to apply it to
dynamic images
that reference
external images:
You cannot set a scanline orientation for any external images you place in a
folder. However, if you use the Image Downloader to download images to the
printer disk or the local PlanetPress Design Suite virtual disk, you can set the
scanline orientation for any bitmapped images it downloads.
13.14.7 Image Contents
The guidelines here apply to the content of image files, and are intended to provide some insight into the
characteristics of image files that can increase the runtime processing images require.
Guideline: Avoid images with many color gradients.
Applies to: Bitmapped, vector, and metafile images
Advantage: In the case of bitmapped images, color gradients reduce the amount of compression the
image file can use. In the case of EPS images, color gradients increase the processing
time the images require. In both cases, they increase the file size of the document.
Guideline: Avoid complex EPS and PDF files that include bitmaps.
Applies to: Metafile images
Advantage: Decreases the amount of processing time the EPS and PDF files require.
