Page segments and images

Page segments and images only print in color if there is no conversion by PSF from 240 pels to 300 dpi. If a conversion is required, PSF converts the page segment or IM image to an IOCA image. This conversion strips the color bit from the data stream.

Note these factors when printing IM images in color:

•

•

•

The PGD (unit of measure) structured field may be added to the page or the overlay that contains the page segment or inline image. The PGD within the resource that includes the image is the relevant structured field. In the case of an overlay, if the PGD is set correctly for the overlay, the IM image will print in color even though the page containing the overlay does not match.

Changing the PGD unit of measure value manually will affect text placement and image handling. Therefore, you should use caution if you wish to change this value.

One way to avoid this problem is to isolate the image into a separate overlay that does not contain text. You can then change the PGD unit of measure for this overlay without affecting any other text or images on the page.

Changing the IID value manually will affect the size of the printed image. If you change the value from 240 to 300, the image will print 4/5ths its original size.

For these reasons, the last combination in table 4-1 (shown on page 4-10) is the best. Applications that generate AFP at 300 dpi tend to use 1440 as the PGD unit of measure.

For example, when Using Elixir Desktop for AFP, an overlay generated at 300 dpi generates 1440 PGD. As a result, you do not need to make any manual hex edits to the structured fields.

Also, after you apply PTF UN78384, OGL will generate a PGD unit of measure at 1440 dpi when used with a 300 dpi font library. This change causes any 300 dpi page segments included in an overlay to print in color.

If you wish to change your applications at the hex level manually, the relevant structured fields are:

•

•

PGD1 x’D3A6AF’

page units per unit base (XpgUnits and YpgUnits)

IID x’D3A67B’

image points per unit base (XUnits and YUnits)

and the relevant values are:

•

•

•

for 240 dpi: x’0960’

for 300 dpi: x’0BB8’

for 1440 dpi: x’3840’.

Using Elixir Desktop for AFP

If you have converted a black and white page segment to Elixir format, you can copy that image into a form. To change the color, select the image, then select a color with the left mouse button.
