Ive a script to generate an image using imagemagick in PHP, after designing i need to create a pdf to print and this pdf need to be like a vector one, even if we zoom in the content should be crisp, but my pdf is not so, can some one guide me how to achieve this?
Do i need to convert my final png as svg? or is it possible to make pdf with PNG as vector?

I need to manipulate images on the server-side via PHP. I use ImageMagick for that purpose, and there are a lot of great functions, but no documentation...
The issue is the next:
I have two images a png with a transparent background, and a jpg one;
I need to change the JPG image that has the same shape as the visible part of the PNG.
I don't want to crop the image, but to adjust to the PNG's visible part. Is that possible to do?
Example:
I am using dompdf to generate a PDF file. The PDF simply contains texts. I need the content of the PDF to show as an image instead of texts. I do not know where to start. Cannot find anything using Google. Any suggestions?
More info:
In the PDF I currently generated, I can select specific portion of texts by highlighting it using the mouse. In the PDF I should generate, I should not be able to select portion of texts because the texts is already an image. So the PDF I should generate contains an image, and the image contains the texts.
You could generate a png first using phpgd / ImageMagick then shove it through dompdf
I'm using tcpdf to generate a pdf file, and have to conditionally convert coloured SVG files to grayscale.
But i'm not able to find any useful libraries to do that.
Is it even possible?
PS! I dont have imagemagick
I want to convert PDF pages to JPEG, but I want each page to be converted to 3 images.
First one is high quality
Second is mid quality
Third is thumb images
I use this code but I did not know how to make it to 3 images:
$im = new Imagick();
$im->setResolution(100,100);
$im->readImage("files/xx.pdf");
$im->setImageFormat('jpeg');
$im->writeImages("files/oman/oman.jpg",false);
This code will only convert each PDF page to one image.
Once you've created the first high res version of the page as a jpg, then just use php gd to resize it by reading in that generated jpg and resizing it down and exporting another jpg. This is the function you want and that page shows a simple example of how to resize images.
UPDATE: This shows a pretty simple tutorial on how to resize with php
UPDATE: Sorry, look at the php.net link above, there are many many examples of how to resize an image, here is a simple one. All you need to do is take what is returned and use imagepng() to save the file locally. (There are similar functions to save gif/jpg)
I'm trying to layout a business card on a PDF with the FPDF class using a form field that the user fills out. I have been able to create the text needed for the card, but I have a logo that I want to output as well.
The problem I am facing is that I can only find a way to add an Image as a JPEG and it looks pixelated when the user zooms in on the PDF. Is there a way to output a vector file on the PDF so when the user zooms, it retains the crisp quality?
Here are the methods that FPDF allows: http://fpdf.org/en/doc/index.php
http://fpdf.org/en/doc/image.htm
So GIF, JPEG, PNG are supported. Using pure the FPDF library you should convert the images to a valid type.
However extensions are there ;)
