|
|
<p>The image print transform is an i5/OS® function that is capable of converting
|
|
image or PostScript data streams into various ASCII and non-ASCII printer
|
|
data streams. The conversion takes place on the iSeries server, which means
|
|
the data stream generated is independent of any printer emulators or hardware
|
|
connections.</p>
|
|
<p>The image print transform function converts image or print data from one
|
|
format into another. A supporting printer interprets the resultant printer
|
|
data stream. The image print transform function can convert the following
|
|
data streams: </p>
|
|
<ul>
|
|
<li>Tag Image File Format (TIFF)</li>
|
|
<li>Graphics Interchange Format (GIF)</li>
|
|
<li>Windows Bitmap (BMP)</li>
|
|
<li>PostScript Level 1 with DBCS extensions</li></ul>
|
|
<p>The image print transform function can generate the following printer data
|
|
streams: </p>
|
|
<ul>
|
|
<li>Advanced Function Presentation Data Stream</li>
|
|
<li>Hewlett-Packard Printer Control Language (PCL)</li>
|
|
<li>PostScript Level 1</li></ul>
|
|
<p>Similar to the host print transform function, the image print transform
|
|
function converts the data on the iSeries server instead of an emulator.</p>
|
|
<p>When a data stream is converted by the image print transform function,
|
|
the printer data stream that is created contains a bit-mapped image. A <span class="italic">bit-mapped image</span> is an array of numerical values. Each
|
|
value represents part or all of a <span class="italic">pixel</span>. A <span class="italic">pixel</span> is a single point or dot of an image. An image is usually measured
|
|
in terms of pixels, for both width and height. The <span class="italic">resolution</span> of an image is then defined as the number of pixels (dots) per unit
|
|
of measure. For example, a resolution supported by many printers is 300 dots
|
|
per inch (dpi). Therefore, an image having dimensions 1200 pixels by 1500
|
|
pixels would have a width of 4 inches and a height of 5 inches when printed
|
|
at 300 dpi.</p>
|
|
<p>The image print transform function works with ASCII printers as well as Intelligent Printer Data Stream™ (IPDS™) printers that have AFP(*YES) specified
|
|
in the configuration. When the image print transform function is used, the
|
|
transform does not take place until after the data stream is spooled. Then,
|
|
when the spooled file is printed or sent to a remote output queue, it is first
|
|
sent to the image print transform function to be transformed. Printing with
|
|
the image print transform function is done automatically when:</p>
|
|
<ul>
|
|
<li>A printer device is created with the host print transform function enabled.</li>
|
|
<li>The device or remote output queue has an image configuration object defined.</li></ul><p class="indatacontent"> For more information about creating a device with host print transform
|
|
enabled, see <a href="rzaluconfhpt.htm#rzaluconfhpt">Configure host print transform</a>.</p>
