back to thumb or PDF document story or
the Sun how to create or did I already
mention it
well how to create a PDF documents let's
get started and create a new class
out just call it that stuff this is what
many people if you ask me how to you
actually edit stuff in a
PDF document so that's the main focus on
this tutorial
on how to at its the text or what not
a text but at a some content of the PDF
document
and two import the most important
classes
the first one being the calm
I texts PDF start texts
PDF PDF reader we can get started
I okay though didn't make sense okay
number
so with the sexy assist copy that the
second part is going to be the new one
it's not going to be the PDF reader his
car to beat the PDF
stepper I miss you
so we're going to talk about it the PDF
staff to which that's basically
like copy the file for us
and then save it as the file again so
we're going to do that in this tutorial
and to do that we also need
the saba I who file OutputStream
okay so now that we have everything
important let's create our main method
I'll to say public static void main
straying know what their
a string rx have an answer
was created rpf reader
so to say PDF freezer reader
equals you p d
F reader around this country asks for a
string
which is going to be the file name:
soul from last time else is to use the
funds to PDF file
of course if you wanted to use the
super or some document you can do that
as well
and then describe to you thrown arrow so
we have to
surround it with the try and catch block
which you personality don't like because
it's just
too much water to do
for okay we have to do it K
so now that we have to try catch block
done
length actually create the PDF stampers
all week so we can save PDF staffer
Stamper
equals to you you PDS timber
and going to take to preface so
the first parameter is going to be PDF
reader
which we have up here 3 just conceive
reader
the second preference for to the
vote see the file OutputStream salts is
the file out
but stream
and its basic it works basically the way
llegas
like I told you so it copies the
PFR into the Stamper re-edit and then at
the end for you want to save it again
and so with the follow up the street
became specifies that name
want to save it s Elsass save it as
fonts to you PDF that's the way
goes so one thing to note
is that the of that the Stamper
can only be created once for each
PDF reader so 1 p.m. for you can only
have faltered after
which means if you're not sure if
a Stamper has or if every house already
been used twice
by a staffer you can simply
ask it by I getting the
is tempered Julia so you can see system
doctor
pretty line reader about is tempered
heavy is tampered will be is going to
return
whether or not is PDF reader has already
been
Stamford or not and that we can do
cultists for Tim's demonstration
purposes I'll do that down
there as well so if we found that
you can see the first values fault and
then the second valleys true
because at first we didn't create the
PDF's temper but then it second
dates which is why I return true affect
so that some insight not you have to
remember
if you are you think the Stamper
excessively kept so
what can we actually do TPS tempers so
for now
not too much purchased open up a PDF
document
and if it is hits command I
you can see there's title an author and
is subject so we can at it those
those three things in our RPS tamper
so rare probably not too exciting but
for the next
couple tutorials real need for you pDF
Stamper
for now we'll to start off with those 3
thinks and to do that we need to
imports Celtic first so we have to
import the child out
you till dot map
so if you don't know what the map is
you are going to learn now and if you
don't know works collections are then
it's going to be a little difficult to
understand or
screen to look a little in cryptic but
trust me it's not that hard
such as type in map van those of
this call those last in Sin City
creative in science
van in those triangular census called
and trailers from now
just type in to works string call by Sri
than outside of the map just give it a
name like
info venice is going to create
a new map which is going to contain
two strings if you'd well to if you
don't know what the map is
held just get to that in a minute and
now to initialize
that info which is to say info equals
two
reader dot gets
info
and so now we have the information about
the PDF reader
and from there we can pretty much edit
this content so we can see
info dot puts
than so a map is going to take to values
spawn St key-value have you other one is
to come
to be the value value
yet right soho for instance
if I type in author this going to be the
key
and then fee of the of course me
stipend Felix for its
van I think about god's little bit adult
with clear
what's keys and all these are a map so
to store Stata
one is the key for instance the author
and then the other one st valley itself
or in this case
city of the itself and so we can do
that for the keys I showed you
a moment ago so we can see info dot
put down the key for instance is
title and
as the valley want to say title is
falling
its did and last but not least just put
another
value in the sold say in food
put subject and as a subject
hold says typing working
with fonts is file
year okay a
now that we have every information you
want to have an our
perhaps Storch we can putting our
stepper
the stamp is going to use that
information to put it in though
vast funds to a PDF file so we can say
Stamper
taught fat
more info to you info
now we have actually everything done
to edit the PDF file half the author
title subject
ever and saved in our phones to the PDF
file
and the last but not the easiest we have
two
close the Stamper again
sense if the file output stream as well
so
that's going to quit the program
securely
and then waters run the program
refresher open it
but I that it can see too tightly fung
offers me and then the subject is
working with phones is fun
way yell so
arkin not too exciting for now
bucks so we are going to use the PDF
staffer
for pretty much anything that has to do
with
editing différents documents
so look out for those tutorials health
I hope to see you next time thank you
for watching
