Chapter 2: Compiling Y our Application This chapter provides information for compiling your appl ication with either archiv ed or shared libraries for the following Application Programming Interfaces (APIs): Starb ase, HP-PHIGS, and HP PEX. Compiling examples are given for C, Fortran, and Pascal. The actual pathnames of the conceptu al (< ita li[...]

By default, the linker program ld(1) looks for a shared library driver first and then the archive library driver if a shared library was not found. By using "-Wl,-a,archive" (o r exporting the LDOP TS variable), the -l option will refer o nly to archive drivers. Because the archive library libhpgfx1 .a references functionality in libXext.[...]

Compiling with Ar chive Libraries If you are using archived libra ries, you need to include your device's driver library. ___________________________________________________________________________________ Note : Shared libraries are used by de fault unless you specify that you want to use archived libraries (by specifying "-Wl,-a,archive[...]

A display name of the form unix:0.0 will f o rce th e use of Unix Domain Sockets (UD S), which is identical to the local transport used befo re HP-UX 10.20. A display name of the form nn.nn.nn.nn:0.0 (where nn.nn.nn.nn is an IP address) will force the use of Internet Sockets, which is the rem ote transport normally used, and which can be used local[...]

In either case, the format and m eaning of the fields is the same: <region_size> [, <high_water> [, <buffer_size> ]] with no em bedded blanks, e.g. 32000,16000,5000 32000 0 Although the default is " SMTSizes 0,0,0, " a specification of " SMTSizes 100000,90000,90000 " is optim al in most situations if SMT is des[...]

Enabling and Disabling of SMT The special value of 0 for Region Si ze specifies that SMT is to be disabled. Disabling SMT removes it from the Xserver causing it not to be available fo r any transports. Any non- zero Reg ion Size enables SMT on the Xserver. The default Region Size for a di skless Xserver is zero (disablin g SMT from the Xserver) to [...]

HP Color Recovery Color Recovery is a technique that generates a better picture by eliminating the graininess caused by traditional dithe ring tech niques.

Dynamic Loadin g HP's X server now dynamically loads the appropriate device drivers and extensi ons based on the target graphics display device and the extensions the device driver supports. This feat ure should be transparent to X server users. When possible, the loading of X extensions is deferre d until the first protocol re quest is encoun[...]

For example: Screen /dev/crt/ ScreenOptions EnableIncludeInferiorsFix This gives a system administrato r control over when th e fix is active and when it is not. In this way, each site can evaluate whether or not it is beneficial to en able this fix. Shared Memory Usage With 3D Graphics Graphics processes use shared memory to access data pertaining[...]

It is also possible to decrease th e size of GRM shared memory. You ma y want to do this if you want to reduce the swap-space requirements of your system and/or you do not intend to run any 3D graphics processes. For example, you could reduce graphics shared mem ory size to 0x100000 (one megabyte). Count Transparent In Overlay Visual In some config[...]

__________________________________________________________________________________ Note: The on-board and "card" versions of the same device can be considered identical; for example, you could use an on-board HP VISU ALIZE-EG graphics device and an HP VISUALIZE-EG graphics card, and still consider them identical devices , thus perm itting[...]

____________________________________________________________________________________ Note: DHA (Direct Hardware Access) is not supported in a window that spans multiple screens. This means, for example, that while graphics is suppor ted to a window spanning two or more screens, accelerated graphics is not. "Spanning," in this co ntex t, i[...]

This behavior is the result of HP VUE's naive assum ption that it is running against o ne large screen; it centers these windows accordingly. If you are using the default HP VUE key bindings, you can easily reposition the Fron t Panel so that it is completely contained within on e physical screen: 1. With the input focus on the Front Panel, pr[...]

For example, to configure SLS/d slave X servers on hpslsd1 , hpslsd2 , hpslsd3 , and hpslsd4 , do the following as root : • Copy each system's /etc/X11/X0screens file to /etc/X11/X50screens (the use of "50" as the display name is an SLS/d convention only; you can choose any number from 0-99 that m eets your needs). Unless you'[...]

Edit the /etc/X11/X0screens file and enter: SingleLogicalScreen 1 4 hpslsd1:50 hpslsd3:50 hpslsd4:50 hpslsd2:50 Then, on the master system, make sure that SLSd_d aem on is running and enter in it state 4 (e.g., as root: /etc/init 4). You will notice all of the slave X servers starting in turn, then finally when the m aster initializes, you will see[...]

The modes are set from the Boot-Admin at bootup tim e by selecting from the menu of options a configuration that supports double-buffer or not. From that point on (without reboo ting) the server will use the selected mode. Eight-plane mode is compatible with the Integra te d Color Graphics device. It has eight image planes and uses only software do[...]

To obtain hardware double-buffering, find a visual in the image planes. The best m ethod is to find all the depth-8 PseudoColor visuals returned by XGetVisualInfo and then eliminate the visuals that are reported in the SERVER_OVERLAY_VISUALS property (discussed below). If you have an application that assumes the defau lt visual has fast double-buff[...]

hp-HIL input devices can plug into other hp-HIL devices, with up to seven input devices connected together. If there are no DIN input devices connected, and there are multile hp-HIL in put devices, the following algorithm is used to choose an X keyboard and pointer device. 1. If no explicit specification is made through the X*devices file, the last[...]

Explicitly Specifying Input Device Use The X server can be explicitly configured to use a sp ecific input device as the X poin ter or X key board, or merge the data from an input device with that fr om the X pointer or keyboar d. This configuration is done by adding information to the X*devices file. Ther e is one syntax to use for hp-HIL devices, [...]

The following example specifies a Spatial System Sp aceball® connected to the serial port associated with device file /dev/tty0p0 as the X pointer: Begin_Device_Description Name spaceball.1 Path /dev/tty0p0 Use pointer End_Device_Description More examples of input device specificati ons for RS-232 input devices are in the /usr/newconfig/etc/X11/X0[...]

This syntax should not be used if more than one X server will be run on the same computer, or if non-X programs will be directly accessing input devices. Th e X serve r interprets "first" to mean "first accessible", so you may not always get the first on the hp-HIL, just the first one not already in use. Selecting Values for X*d[...]

If you had a more complicated configuration, such as two graphics tablets, two keyboards, and a barcode reader, your X*devices file could look like this: • first tablet pointer The p ointer • second tablet other Merged with the pointer • first keyboard other Merged with the keyboard • second keyboard keyboard The keyboard • first barcode [...]

Redefining the hp-H IL Search Path The X*devices file can be used to redefine the path searched for hp-HIL devices . By default, the path searched is /dev/hi l. The device files are nam ed by appending the numbers "1" throug h "7" to the path. The path is redefined by adding an entry to the X*devices file with the following form[...]

Initializing the Colormap with xinitcolormap The xinitcolormap client initializes the X colormap. Specific X colormap entries (pixel value s) are made to correspond to specifie d colors.

Why Is Gamma Co rrection N eeded? The intensity of light generated by a conventional monitor is non-linear with respect to the signal applied. The intensity output is approximately equal to the applied voltag e rais ed to a power. This power is referred to as the gamma of the monitor. State d mathematically, intensity = voltage gamma For example, t[...]

Monitor Brightness and Cont rast Often, the brightness control on a mo nitor is boosted to compensate fo r im ages that look dim due to a lack of gamma correction. Before applying gamm a corr ection, the monitor brightness should be adjusted so a blank screen looks black in t ypical viewing conditions. Next, display a picture that is predominantly [...]
