I use the command wkhtmltopdf https://www.google.com output.pdf to get a file of pdf.
I got the pdf, the result is successfully,
but I write codes that use the library Podofo,
the text is upside down.
PdfMemDocument document;
PdfPainter painter;
PdfPage* page;
document.Load( "output.pdf");
page = document.GetPage(0);
painter.SetPage(page);
PdfString eNtext((const pdf_utf8*)"Test");
PdfFont* pFont = document.CreateFont("STHeiti Medium", false, new PdfIdentityEncoding(0, 0xffff, true));
painter.SetFont(pFont);
painter.DrawText( 10.0, page->GetPageSize().GetHeight() - 100, eNtext);
painter.FinishPage();
document.Write("output2.pdf");
Please help me, How can I do it?

I'm trying to capture whole desktop screen (front buffer) and add a logo and caption to each frame.
I load the logo (.png or .jpeg file) as IDirect3DTexture9 and I try to add it to a IDirect3DSurface9 image frame (screenshot).
As I'm new to DirecX9, I have no idea how to copy the logo (texture) to the screenshot (surface/buffer). Any help would be appreciated.
(If there's any other way to add logo to each frame without involving texture, please do tell me.)
EDIT:
I have used the code suggested in an answer below. The hr result returned is an error.
IDirect3DSurface9 *pSurface = NULL;
pDevice->GetFrontBufferData(0, pSurface); //my screenshot
LPDIRECT3DTEXTURE9 tex = NULL; //my logo
//[code to load logo from file here]
IDirect3DSurface9 *pSurf = NULL;
tex->GetSurfaceLevel(0, &pSurf);
hr = pDevice->StretchRect(pSurf, NULL, pSurface, NULL, D3DTEXF_NONE); //HR GIVES AN ERROR
You can use StretchRect.
The code will look something like this (pseudo):
ID3DSurface9 *pScreenSurface = ... // your screenshot surface should be created in default pool and the same format as your texture(see bellow), like this:
CreateOffscreenPlainSurface(width, height, D3DFMT_X8B8G8R8, D3DPOOL_DEFAULT, &pScreenSurface, NULL);
// Now get a screenshot by using either GetFrontBufferData, or GetBackBuffer/GetRenderTargetData by supplying pScreenSurface as a parameter (not shown here).
ID3DTexture9 *pTexture = ... // your texture should be loaded in default pool and the same format as your screenshot surface, like this:
D3DXCreateTextureFromFileEx(*ppDevice, L"icon.bmp", 40, 40, D3DX_DEFAULT, 0,
D3DFMT_X8B8G8R8, D3DPOOL_DEFAULT, D3DX_DEFAULT, D3DX_DEFAULT, 0, NULL,
NULL, &pTexture);
ID3DSurface9 *pSurf;
pTexture->GetSurfaceLevel(0, &pSurf); // don't forget to Release pSurf after StretchRect
RECT rc = { ... initialize the destination rectangle here };
pDevice->StretchRect(pSurf, NULL, pScreenSurface, &rc);
You need to specify a destination rectangle inside the destination surface, where you want your texture to be copied.
I want to print the captions imported from facebook/instagram in an image and save it. I want to do this using imagick library with php as I am creating the base image using imagick. The normal text prints properly but the emojis that are imported do not get printed as emoji's. Can anyone suggest how emojis can be printed using imagick.
What I have tried:
$eachpageimg = new Imagick ();
$eachpageimg->setResolution ( 300 , 300 );
$eachpageimg->newImage (1050, 1260 , 'rgb(255,255,255)');
$eachpageimg->setImageUnits(imagick::RESOLUTION_PIXELSPERINCH);
$eachpageimg->setImageFormat ('jpeg');
$eachpageimg->setImageCompressionQuality(100);
$draw = new ImagickDraw();
$pixel = new ImagickPixel( 'rgb(255, 255, 255)' );
$pixel->setColorValue(Imagick::COLOR_ALPHA, .8);
$draw->setStrokeColor('rgb(0,0,0)');
$draw->setFillColor ('rgb(0,0,0)');
$draw->setFont ("ROBOTO-REGULAR");
$draw->setFontSize (70);
$xpos = 10;
$ypos = 200;
$eachpageimg->annotateImage($draw, $xpos, $ypos, 0, "Gshdh😚😎😑😚🤠");
$filename = 'saved.jpg';
// SAVE FINAL page image
file_put_contents ($filename, $eachpageimg);
The font you are using needs to have the emojis in them. This can be checked by just editing a word or web page with that font set.
However:
"Gshdh😚😎😑😚🤠"
Those look very much like a mucked up character set rather than emoji. I strongly suspect that you are saving some data in a character set that doesn't support emoji (i.e. most non-UTF) character sets.
Exactly where that has happened will need to be something you discover yourself.
I'm trying to add a PNG image to an existing pdf, but the transparency is converted to black color.
PdfReader reader = new PdfReader(pdfPath);
File f = new File(pdfPath);
String result = f.getParent() + File.separator + UUID.randomUUID().toString() + ".pdf";
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(result));
Image image = Image.getInstance(ImageIO.read(new File(imagePath)), null);
PdfImage stream = new PdfImage(image, null, null);
PdfIndirectObject ref = stamper.getWriter().addToBody(stream);
image.setDirectReference(ref.getIndirectReference());
image.setAbsolutePosition(30, 300);
PdfContentByte canvas = stamper.getOverContent(1);
canvas.addImage(image);
stamper.close();
reader.close();
How can I keep transparency?
First this: I am violating the policy at iText Software by answering this question. You are using an old version of iText, and the policy dictates that voluntary support on iText 5 or earlier has stopped. You should either use iText 7, or you should get a support contract if you still want support for an old iText version.
However, I am curious. I want to know where you found this clunky code (or why you decided to write this code):
Image image = Image.getInstance(ImageIO.read(new File(imagePath)), null);
PdfImage stream = new PdfImage(image, null, null);
PdfIndirectObject ref = stamper.getWriter().addToBody(stream);
image.setDirectReference(ref.getIndirectReference());
image.setAbsolutePosition(30, 300);
PdfContentByte canvas = stamper.getOverContent(1);
canvas.addImage(image);
You don't need ImageIO and you don't need to create a PdfImage, nor do you need to add that image to the body of a PDF file. The code you are using is code specialists would use for a very particular purpose. If you know that particular purpose, please explain.
If adding an image at an absolute position is all you want to do (that's a general purpose, not a particular purpose), your code should be as simple as this:
Image image = Image.getInstance(imagePath);
image.setAbsolutePosition(30, 300);
PdfContentByte canvas = stamper.getOverContent(1);
canvas.addImage(image);
In this case, you don't have to worry about the image mask; iText will take care of that for you.
Please also explain why you're using an outdated version of iText instead of iText 7. If you want your application to be future-proof, you should upgrade to iText 7 now (to avoid wasting time later).
Using Itext 7 for generating pdf and found Anchor tag is deprecated hence used Link.
Link projectNameLink = new Link("**Test**", PdfAction.createURI("https://www.google.com"));
projectNameLink.setFontColor(Color.BLUE)
.setBorder(Border.NO_BORDER);
Paragraph footerContent = new Paragraph().add(projectNameLink).setBorder(Border.NO_BORDER);
Added this to paragraph. The document in Acrobat Reader shows border around Test. Same thing I see in the below Url . Is it a bug ? Or am missing something. How to remove the border ?
Try to download the file
And open in Acrobat Reader on can see borders along the Link Text.
The default behaviour for iText is to add the border.
You can however apply some style to these actions.
PdfAnnotation la1 = new PdfLinkAnnotation(new Rectangle(0, 0, 0, 0))
.setHighlightMode(PdfAnnotation.HIGHLIGHT_INVERT)
.setAction(js)
.setBorderStyle(PdfAnnotation.STYLE_UNDERLINE); // this is what you need
Have a look at http://developers.itextpdf.com/content/itext-7-building-blocks/examples/chapter-6
I had the same problem just wanting to have no border at all, and I've found the solution:
PdfAnnotation la1 = new PdfLinkAnnotation(new Rectangle(0, 0, 0, 0))
.setHighlightMode(PdfAnnotation.HIGHLIGHT_NONE)
.setAction(js)
.setBorder(new PdfArray(new int[]{0,0,0}))
I found out the solution reading the javadoc: http://itextsupport.com/apidocs/itext7/latest/com/itextpdf/kernel/pdf/annot/PdfAnnotation.html#getBorder--
I am writing a script that generates Chinese character worksheets (so students can generate and practice writing)
The script is passed a 15 character string from a form in index.php.
The string is then exploded into an array of 15 elements (each a Chinese character).
The problem arises when I want to use the Write() function to populate the file with these characters, I've used the input to pick appropiate images without any problems but now it's the encoding of the fonts that gives me a hard time.
PS. I need to use a cursive/handwritten font as default 'print' fonts are not suitable for handwriting practice.
Ideally I would like to use HDZB_36.TTF or Sharp Regular Script Font
See the code below as well as images of errors I get with some different fonts.
<?php

// linking TCPDF and FPDI libraries
require_once('tcpdf/tcpdf.php');
require_once('fpdi/fpdi.php');
// First retrieve a 15 chinese charcters long string from POST form in index.php
$hanzi = $_POST["hanzi"];
// Explode the hanzi into a 15 items array
function mb_str_split($hanzi){
return preg_split('/(?<!^)(?!$)/u', $hanzi);
}
$charlist = mb_str_split($hanzi);
// Define starting y positions of each line of the grid
$yPos1 = 10.71;
$yPos2 = 17.94;
// Creating new page with PDF as a background
$pdf = new FPDI();
$background = $pdf->setSourceFile('images/worksheet_template1.pdf');
$tplIdx = $pdf->importPage(1);
$pdf->AddPage();
$pdf->useTemplate($tplIdx, 0, 0, 210, 285, false);
/*
This is where the problem starts, I can manage to display latin characters using helvetica

With some larger (ex. stsong) fonts I get a browser error saying: No data received ERR_EMPTY_RESPONSE (Image 1)
With font 'htst3' the characters appeared upside down and were full of artifacts (Image 2).
With font HDZB_36 the characters were not rendered at all.

Just a suggestion:
The file you generate worksheet.pdfshould perhaps have the same encoding as your letters.
The PDF should have the appropriate encoding, see: https://stackoverflow.com/a/10656899/1933185
