• .PS to GIF conversion - truncates the image

  Hi all

  I have an image file in .ps format. When I try to convert it to GIF or JPEG or PDF, I could see that the image is truncated on the right. But when I change the .ps file to be in landscape mode image conversion is correct.

  But I want the image to be converted to Portrait without truncation of the image mode.

  Can any help me to solve this problem in the .ps file.

  Can do something chnaging the .ps file so that I can get a complete picture

  Thanks in advance.

  Kind regards

  Jawahar

  Your file PS does not contain the parameters of size or page orientation, so the PostScript interpreter you use

  simply defines the configured default page size.

  As the file defines something as a page covering (the name pagebbox is used), take the fiven values it

  to build a State of page size. For example insert

  < agesize="" [792="" 612]="">> setpagedevice

  right after the comment lines (lines starting with two percent signs). Forcing your PS interpreter

  (condition he speaks at least the language level 2, that I take in silence) to make the formula for a

  Letter size page orientation is landscape.

  If you really want a portrait orientyation, you need to swap two numbers in the

  Statement above and enter the code to scale down the formula.

  And now I want to edit this postscript file, and add a .png image to print content. How can I do?

  Thank you very much for your help!

  This indicates that the data is compressed with LZW compression, then this is a compact representation of ASCII-oriented. LZW is used in GIF, but this does not mean that someone dumped a GIF file.

  PNG files using Flate compression, but you can't empty a PNG into PostScript file. Your steps

  1. understand the PostScript imaging model.

  2. understand the PostScript image format.

  3 understand how filters are specified in PostScript format.

  4 completely parse and decompress the PNG. I hope that there can be no alpha channel!

  5 convert the PNG data you analyzed in PostScript.

  6. Add the appropriate image transformations.

  7. Add in PostScript. Discover the point of law cannot be simple.

  Working with formats JPEG is a little simpler, as most of the JPEG files are directly compatible with the DCTDecode filter.

  If you do not have the PostScript language reference manual, you need, and you will need to spend a few weeks or months immersed in it...

• PostScript stack overflow problem

  Hello world

  I am looking for detailed information one

  postsript battery works, what commands are implemented

  on the stack and how you can control the size of the stack

  When creating postscript files. We write a postscript

  driver and our PostScript shows often stack overflow

  Mistakes, but did not find us sufficient information on

  How to avoid this problem nor books ps.

  A stack size is dependent on a particular PS interpreter

  or are there standards? What is a typical stack size?

  What is the best way for the developer to the size of the battery, follow

  so it does not get overwhelmed?

  Thank you very much in advance for any help.

  Yuliana

  I had a look at your sample file. My impression is that these huge blocks of

  PS code of procedures is not quite adequate. Provided the printers that you want to use

  level 3 printers and have enough memory or - even better - a hard

  disk, I suggest using the filter ReusableStreamDecode place such as outlined below:

  To set up:

  CurrentFile <0 (%endofchunk)="">> > ReusableStreamDecode filter

  Insert here the % your huge chunk of code PS

  % EndOfChunk

  /name_of_chunk exch def

  To use:

  name_of_chunk dup resetfile cvx exec

  Of course, like Dov post earlier, the details of storage management are highly

  dependent development implemented, but I think reusable data flow data are probably

  managed outside the memory 'normal' namagement, e.g. saed on a hard drive,

  If present, or a virtual or similar disc.

• Remove the entry from the ARP table

  I need to create a program to remove an entry in the ARP table in Windows 7 with LabVIEW and TestStand.  The test that I develop contacts ESA via Ethernet.  Each HAD has the same IP address at the beginning but different MAC addresses.  I note that there may be long delays in test is running when you try to connect and remove the previous entry in the ARP table seems to help.  But now I have to do it manually through the command line.  The command 'arp d' requires elevated privileges.  I had a hard time getting LabVIEW to raise the system exec.  Does anyone have an ideas? Is there a .NET access to the ARP table?

  Thank you

  Paul

  I'll try to look into ARP sync settings setting in Windows.

  We have suffered from various problems of connection-performance TCP a few years ago and our solution was to change the default number of TCP sockets and delays (we knew port exhaustion). The tweeks eliminated most of our problems, no changes to code LV/TS not required.

  I tried to find info on ARP parameters for Windows 7, but it seems that there is much less info available that ther is for XP.

  Key words of the most common registry for older versions of Windows have been 'ArpCacheLife' and 'ArpCacheMinReferencedLife.

  EDIT:

  These parameters were apparently kidnapped in Vista. I found this on the site of $ M; they can apply to later versions, as well as M$ is a request for change to the management of the ARP...

• Limiting the tables and using lindex in commands regexp

  Hello

  Here's my second and extremely crap question/post in what concerns the EEM/TCL.  I did some research on Google and have not really been able to find an answer to these questions.  Probably more due to my lack of agility with the search bar of the information being just is not there.  Hope you'll forgive me if.

  1. my first question is this.  Say I want to get an output of a command.  I would like to see all the interfaces in the 'ip vrf command show interface' for example.  Not knowing how many interfaces there may be, there could be 10, or there might be 200, what is the best way to limit a loop function after that I gave the following commands?

  Set _vrf_int [exec show ip vrf interface]
  Set _array_vrf_int [split $_vrf_int '\n']

  set $i 0

  then {$i< 200}="">
  RegExp {([A-Z]+[a-z]+[0-9]+). *} [lindex $_array_vrf_int $i] _complete_string _int
  Inc. $i 1

  }

  Not 100% sure that the syntax is correct, sorry.  If I don't have that 10 interfaces so it won't be necessary to issue this loop 200 times to "$_array_vrf_int".  Also wouldn't be great if I went through the 200 interfaces.  Is there a way I can limit this loop based on the number of lines that were captured after the split function?

  2. the value of the regular expression above is output in the var $_int.  Is there a way I can output the regular expression in a table? a ' :-

  RegExp {([A-Z]+[a-z]+[0-9]+). *} [lindex $_array_vrf_int $i] _complete_string [lindex $ $i _int]

  Syntax is certainly not correct, but I guess there could be a way to do this.  Any thoughts?

  3. I did some comparisons on an outing to see if an access list is present on an interface.  I can get a regexp to pull back the name of the access on a given interface list, but if there are any access-list to an if statement on anything?

  Set _acl_name 0

  RegExp {. * ip access-group (. *) in} $_running_int _complete_string _acl_name

  If {$_acl_name! = 0} {puts ' there is an access-list on $_int "} else {puts ' there is no acl on _int $ :-("} "}

  In the above output I'm defining the value of ' $_acl_name ' to zero so that I can compare it to the fi statement.  This seems to be a newbie to shit how do however.  Is it a kind of generic I put in place of the '0' to match an empty variable. has ' {null}.

  4 I'm sorry last question.  I also reset the variable {null} using a similar wildcard.  Once again I can reset the variable to 0, but it seems just that I do not understand that the syntax well enough and it is without doubt a better method.

  5. I have read several tutorials that cover a lot of bases.  Is there a good reference that anyone can suggest so I don't waste your time with these silly questions?  I'm afraid that the scripts I've studied on this forum are always way above my head.

  Thanks in advance

  Alex

  Assume that the limit of the loop.  Which will never end well.  Instead, use a foreach loop to iterate over the number of lines in the output:

  set vrf_int [exec "show ip vrf interface"]
  foreach line [split $vrf_int "\n"] {
  
        if { [regexp {([A-Za-z0-9]+).*} $line -> int_name] } {
  puts "Interface name is $int_name"
  }
  }
  

  In addition, do not use the variables that start with "_".  Those that are reserved for the Cisco or overall use.  In addition, 'exec' is a single command tclsh.  If you use the EEM Tcl, you will need to interact with the CLI library.  You can watch our best practices guide at https://supportforums.cisco.com/docs/DOC-12757 for some tips and tricks with the use of EEM.

  You can use - all and--inline for regexp all return in a list.  However, given the idea of the loop above, you can also use lappend to each pass:

  set intlst [regexp -all -inline {([A-Za-z0-9]+).*} $output]

  
  set vrf_int [exec "show ip vrf interface"]
  set intlst [list]
  foreach line [split $vrf_int "\n"] {
  
        if { [regexp {([A-Za-z0-9]+).*} $line -> int_name] } {
  lappend intlst $int_name
  }
  }
  
  
  
  You can use "info exist" or simply to check the result of your regexp command to see if a match took place.  See the example above the latter.
  regexp {.*ip access-group (.*) in} $_running_int _complete_string _acl_name
  if {[info exists $_acl_name]} {puts "there is a access-list on $_int"} else {puts "there's no acl on $_int :-("}
  
  You can 'reset' a variable by using the command 'deactivated '.
  One of the best general Tcl references is the "book of the pen:

• Large partition table with the primary key referenced by several child tables

  I tested this procedure and it works perfectly. Although when children tables refer to the key column, after execution of dbms_redefinition.finish_redef_table they all are referring to table exercised. In test I deal forced FK droped on tables children and recreated them. What could be the best way to do this in this scenario?

  Thanks for all comments/opinions!

  Are you sure? You should end up with the original FK constraint (disabled and renamed to have a prefix of $$ TMP) pointing to the staging table (which is of course the famous original table), and allowed a new constraint with the correct name, pointing to the new version of the table. so all you need to do to bring order to the top is to remove the constraint of renamed.

  This running-in of the SCOTT schema clearly indicates:

  create the table deptint in select * from dept where 1 = 2;

  exec dbms_redefinition.start_redef_table (user, 'dept', 'deptint')

  n number of var

  exec dbms_redefinition.copy_table_dependents (user, "dept', 'deptint', DBMS_REDEFINITION.") CONS_ORIG_PARAMS, TRUE, TRUE, TRUE, TRUE,: n)

  Print n

  exec dbms_redefinition.finish_redef_table (user, 'dept', 'deptint')

  Select CONSTRAINT_NAME, CONSTRAINT_TYPE, TABLE_NAME, user_constraints STATE;

• Create a view of RDF in Oracle 12 c of tables in an Oracle 11 g Server

  Hello!

  I have a relational database in Oracle 11 g server, but I need to create the view of RDF model in Oracle 12 c in the base tables.

  I created a database connection to connect to the server of Oracle 11 g Oracle 12 c, using the statement:

  CREATE DATABASE LINK myDBLink

  CONNECT to user_test

  IDENTIFIED BY test123

  WITH THE HELP OF '(DESCRIPTION=)

  (ADDRESS = (PROTOCOL = TCP)(HOST=192.0.56.158) (PORT = 1521))

  (CONNECT_DATA = (SID = orcl)))';

  The works of the SELECT statement:

  Select * from EMP@myDBLink;

  I also created a SYNONYM:

  CREATE the SYNONYM MY_EMP FOR EMP@myDBLink;

  The SELECT statement with the synonym also works:

  Select * from EMP@MY_EMP;

  Well, to create the view of RDF, I use a sem_apis.create_rdfview_model function. Now, I wrote the statement of the following two ways:

  BEGIN

  () sem_apis.create_rdfview_model

  Model_name = > "test_linked"

  tables = > SYS. ODCIVarchar2List ('MY_EMP', 'MY_DEPT'),

  prefix = > ' http://GrDF/ ',

  Options = > ' COMPLIANCE = you

  );

  END;

  BEGIN

  () sem_apis.create_rdfview_model

  Model_name = > "test_linked"

  tables = > SYS. ODCIVarchar2List('EMP@myDBLink','DEPT@myDBLink'),

  prefix = > ' http://GrDF/ ',

  Options = > ' COMPLIANCE = you

  );

  END;

  And I get the following error:

  ORA-13199: fetchTabIDList: not found in tables:

  ORA-06512: at the 'MDSYS. SDO_RDF_INTERNAL', line 14308

  ORA-06512: at the 'MDSYS. SDO_RDF', line 3616

  ORA-06512: at the 'MDSYS. RDF_APIS', line 1253

  ORA-06512: at line 2

  
  

  I use examples of book of the Oracle tables.

  
  

  Thank you

  
  

  Yenier
  

  Yenier,

  Could you please try creating a view rather than a synonym? Here is an example:

  SQL >-create dblink

  SQL > create public database link

  2 mylink

  3 connect to

  Scott 4

  5 identified by

  6 Tiger

  using a 7 ':/';

  Database link created.

  SQL >

  SQL >-create view local using queries involving remote database objects

  SQL > create view dblink_scott_EMP in select * from EMP@mylink;

  Created view.

  SQL >

  SQL >-add the primary key (help requests on Direct mapping according to models RDFView to have shorter SubjectMaps)

  SQL > alter view dblink_scott_EMP add constraint pk_EMPNO primary key (EMPNO) disable;

  Altered view.

  SQL >

  How can I check, it's a table really compressed or OWM not in?

  Hello

  This is the right way to determine whether a table enabled version uses compression.  It could be another property table or tablespace that causes the same error will be triggered.  It is difficult to know exactly without the full table DDL.  If the dba_tables query was ACTIVE for this column, the inner workings of the Workspace Manager would have to set as unused column instead of a fall that could have prevented this error.  This behavior has been updated in 12 c to always define the column as unused anyway.  As a on 11.2.0.3, you can use ignore_last_error to jump the abandonment of all columns of metadata (version, nextver, delstatus, ltlock and createtime/retiretime if history is used).  Then when DisableVersioning is complete, you can issue the unused column from the game DDL manually for each of the columns.

  Kind regards

• Tables activated moving version of one tablespace to another - what is table of _LCK?

  Hi all. This is my test script:

  
  

  CREATE THE SCHEMA OF THE TABLE. TEST_TABLE

  (

  ID NUMBER NOT NULL, (38)

  DCA_ID DCL_DCAID_CK NUMBER (38) CONSTRAINT NOT NULL)

  TABLESPACE OLD_TBLSPC;

  CREATE A UNIQUE INDEX SCHEMA. TEST_TABLE_PKC MARKET SCHEME. TEST_TABLE

  (ID)

  LOGGING

  TABLESPACE OLD_TBLSPC;

  CHANGE THE SCHEMA OF THE TABLE. TEST_TABLE ADD CONSTRAINT TEST_TABLE_PK PRIMARY KEY (ID) WITH THE HELP OF INDEX SCHEMA. TEST_TABLE_PKC;

  CREATE A UNIQUE INDEX SCHEMA. TEST_TABLE_UK MARKET SCHEME. TEST_TABLE

  (DCA_ID)

  LOGGING

  TABLESPACE OLD_TBLSPC;

  exec dbms_wm.enableversioning('SCHEMA.) TEST_TABLE', 'VIEW_WO_OVERWRITE');

  exec dbms_wm.beginddl('SCHEMA.) TEST_TABLE');

  modify the table schema. TEST_TABLE_LTS move tablespace NEW_TBLSPC;

  exec dbms_wm.commitddl('SCHEMA.) TEST_TABLE');

  
  The tables and _LT moved to NEW_TBLSPC, but not the table _LCK.

  Select table_name, tablespace_name dba_tables where table_name LIKE '% table_test ';

  TEST_TABLE_LCK	OLD_TBLSPC
  TEST_TABLE_AUX	NEW_TBLSPC
  TEST_TABLE_LT	NEW_TBLSPC

  Is there another method to move the _LCK table?

  Hello

  The _LCK table is only moved to the new tablespace when the created on the top level view of triggers INSTEAD OF are changed.  This only happens when there is a modified column definition, the trigger that is defined by the user or the unique/foreign key constraint.

  Kind regards

• Partitioned table of LOB - àen SECUREFILE?

  Dear administrators,

  My version of DB - 11.1.0.7

  I need to convert storage LOB in BASIC NAVIGATION (and also to enable compression Adv LOB) on a partitioned table (Hash, 64 partitions). Table of the LOB chunk size size - 8 GB, segment - 1.2 to

  I am familiar with dbms_redef for these conversions on non partitioned tables. I know too, redefine a LOB table partitions. But is there a way to achieve BASIC SECUREFILE conversion on a table partitioned using the DBMS_REDEF?

  I have not found much info on this on oracle docs or other sources on the internet. Nobody don't know or don't know of this process? Thanks for your help.
