Hello

i'm trying to create a table with colspan.
Here is the json:

[{},["table",{"header":["col1","col2","col3"]},[["cell",{"colspan":2},"Foo"],"YYY"]]]

i'm expecting a table with three columns and the second row should have a colspan over the first two fields and a third field.
But the result of this code is:

Any idea?

For Maven

For Gradle
This is weird now I'm getting this after installing Maven
`PS C:\Gradle> gradle -v

ERROR: JAVA_HOME is set to an invalid directory: C:\maven

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
PS C:\Gradle> java -version
java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)`

I also ran
iex (new-object net.webclient).downloadstring('https://get.scoop.sh') scoop install gradle
this in cmd not powershell
@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"
But decided not to install it as I realized I just needed to run for gradle to be installed
scoop install gradle

I don't know if this is what I need to do to run gradle, but I ran
`❯ mkdir basic-demo
❯ cd basic-demo
❯ gradle init
Starting a Gradle Daemon (subsequent builds will be faster)

BUILD SUCCESSFUL in 3s
2 actionable tasks: 2 executed`
according to this tutorial

And that's where I got lost and confused and decided to try Maven instead. I think I would rather use Maven since it looks simpler, but after installing it both are not recognizing my Java directory. What do I do?

Hello,

We've come up with the neccesity of inserting an image inside the header of the generated pdf using json-to-pdf.

We tried to tweak the json in order to achieve inserting the image, but as the documentation suggest, json-to-pdf seems to only accept plain text at the moment for the header element.

I saw there's an issue open since, 2016 with something reflecting almost the same neccesity on cli-pdf:

• clj-pdf/clj-pdf#80

Was wondering if any progress was made in order to achieve that use-case, or if it's possible to modify existing json-to-pdf state to at least permitt the "hack" documented by @alemedeiros on the referenced issue.

Would be glad to help if any directions are given on how the change could be accomplished (even though I doesn't know clojure at all i would do my best).

Thanks in advance and thanks for the effort put on the library.

I was getting the same error than others trying to add the repository and library on gradle, so I tried to download the jar (json-to-pdf-0.7.5.jar), copy it to libs folder and add compile files('libs/json-to-pdf-0.7.5.jar') to gradle.

The project compiles fine but when I try to run JsonPDF.writeToFile I get this error:

FATAL EXCEPTION: main Process: com.trecone.jsonpdftest, PID: 14043 java.lang.NoClassDefFoundError: clojure.lang.Var at org.yogthos.JsonPDF.<clinit>(Unknown Source) at com.trecone.jsonpdftest.MainActivity.onCreate(MainActivity.java:121) at android.app.Activity.performCreate(Activity.java:5458) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1093) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2376) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2470) at android.app.ActivityThread.access$900(ActivityThread.java:174) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1307) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:146) at android.app.ActivityThread.main(ActivityThread.java:5593) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1283) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1099) at dalvik.system.NativeStart.main(Native Method)

Hello,

Thanks again for this awesome library.

I'm experiencing a behaviour that i would like to confirm if its expected.

I'm applying the background-color property to a table header, and the color is affecting all the rows of the table.

The json i'm using is the following:

[ { "top-margin":100, "bottom-margin":25, "left-margin":58, "right-margin":44, "size":"a4" }, [ "paragraph", [ "chunk", "Content before table." ] ], [ "paragraph", [ "chunk", "Some other content." ] ], [ "paragraph", [ "chunk", "Content before table." ] ], [ "table", { "header":[ "Row 1", "Row 2", "Row 3" ], "width":50, "border":false, "cell-border":false, "background-color":[ 100, 50, 100 ] }, [ [ "cell", { "colspan":2 }, "Foo" ], "Bar" ], [ "foo1", "bar1", "baz1" ], [ "foo2", "bar2", "baz2" ] ] ]

Wich produces the following pdf:

https://drive.google.com/open?id=1HmBQBF1Os0rijAlDqPWct7mDrYHQ9gD8

Is it expeted behaviour, or the color should only be applied to the header (only the first row)?.

Thanks in advance.

Hi,

I'm wanting to display unicode currency symbols in my pdfs and I haven't been able to work out how to do it. Is this possible?

Thanks!

Hello again.

I think i found another bug:
Here is the JSON I'm using (formatted for better reading):

[
    {},
    [
        "table",
        [
            "c1r1",
            [
                "cell",
                [
                    "table",
                    [
                        "Inner table Col1",
                        "Inner table Col2",
                        "Inner table Col3"
                    ]
                ]
            ],
            "c3r1"
        ],
        [
            [
                "cell",
                {
                    "colspan": 3
                },
                "this should be a rowspan 3 for the complete row 2 of the table"
            ]
        ],
        [
            "c1r3",
            "c2r3",
            "c3r3"
        ],
        [
            "c1r4",
            "c2r4",
            "c3r4"
        ]
    ]
]

This results in a wrong interpretation of the colspan element:

here is the exemple i tried to reproduce

String json = "{\"font\": {\"size\": 20}} \"stuff\" [\"paragraph\", \"foo bar\"]";
JsonPDF.writePDFToFile(json, "doc.pdf");

I'm running it into a groovy script.
I've got an exception

Hi everyone.

I wonder if there is any technical specification like RFC for json-to-pdf. Is there any technical specification like RFC for json-to-pdf?

String doc = "{" +
            "    \"right-margin\": 10," +
            "    \"subject\": \"hello world\"," +

            "    \"doc-header\": [" +
            "      \"inspired by\"," +
            "      \"William Shakespeare\"" +
            "    ]," +
            "    \"bottom-margin\": 25," +
            "    \"pages\": true," +
            "    \"author\": \"someone\"," +
            "    \"header\": \"Page header text appears on each page\"," +

            "  }";

    InputStream inputStream = new ByteArrayInputStream(doc.getBytes());

Hi yogthos,

I'm trying to convert a json object into PDF.
But It is giving me Unknown source exception.

Find the code below.
JSONParser parser=new JSONParser();
Object object=parser.parse(new FileReader("TextFile.txt"));
JSONObject jsonObject = (JSONObject)object;
String jsonString = jsonObject.toJSONString();
JsonPDF.writeToFile(jsonString, dir + "MyFile.pdf");

JSON Object : TextFile.txt
{"balance":1000.1,"num":1000,"is_imp":true,"name":"Object"}

This is the error I'm getting

ERROR c.e.p.s.r.e.GeneralExceptionMapper - An unmapped exception was intercepted

code:

String doc = "[{}, ["paragraph", "hello world"]]";
InputStream inputStream = new ByteArrayInputStream(doc.getBytes());
OutputStream outputStream = new ByteArrayOutputStream();
JsonPDF.writeToStream(inputStream, outputStream);

Given that my hands are tied in that I can only provide an Inputstream why is the impl trying to convert to a Reader and more importantly what can I do to convince it otherwise?

Hi!

I know that pagebreak tag is not in your documentation, but I tried to use it because this simply 'translate' json to your clj-pdf format. But when I try to write to pdf a json that includes ["pagebreak"], it throws the following exception (with stacktrace):

Caused by: java.lang.Exception: invalid tag: :pagebreak in element: ["pagebreak"]
at clj_pdf.core$make_section.invoke(core.clj:665) [json-to-pdf-0.6.9.jar:]

at json_to_pdf.core$_writeToFile.invoke(core.clj:12) [json-to-pdf-0.6.9.jar:]

I tried to follow this on clf-pdf core but I know nothing about clojure. It seems to recognize the :pagebreak tag but then sends the item again to make-section and is not one of the expected values. Could you tell me if I'm doing something wrong or if there is a way of achieve this? Is this tag not going to be available ever in json-to-pdf?

Thanks!

I was trying to generate a smaller chart to display some test data, but the chart still just takes up a full page.

["chart",
{"type":"pie-chart", "title":"System Types", "xscale":0.3, "yscale":0.4, "align":"center"},
["AIX", 21], ["Windows", 23], ["Linux", 345]
]

Also is there a way to disable the grey background for pie-charts? I understand its purpose for line and bar charts, but it is pointless for a pie chart and makes it take up 2-3 times as much space as it needs to.

Hello @yogthos, and once again thanks for this awesome library.

I was wondering if it would be possible to add support to specifying custom font-family in order to be used by the library.

The documentation illustrates that only certain font families are supported; ¿would it be possible to add support?

We would happily contribute if you can give a piece of advice on how to approach the change if needed.

Thanks in advance.

Kind regards.

Hi:

I'm using your library to create a letter head.
Playing around with table for layout, how do you make multiple lines in a cell (for example name + line break + address + line break + phone number)?
I tried multiple paragraphs in the cell to make multiples with no success.

Alternatively, if I used the cells for a new lines, how do I shrink the cell spacing/padding?

Thanks
Juan.

How to create able of contents?
If possible, is it possible to style the table of contents?(font size, line size eg.)

Can you update to last clj-pdf version?
Thanks
