I'm using Imagick to convert PDFs to images. It works great when I convert PDFs oriented in portrait mode. When I try with PDFs in landscape mode, the result is a cropped image. Even if I try rotateImage("#fff",90), the result is also cropped.
Here's the important part of my script:
$imagick = new \Imagick();
$imagick->setResolution(144, 144);
$imagick->readImage(sprintf('%s[%s]', $this->pdfFile, $this->page - 1));
$imagick->mergeImageLayers(\Imagick::LAYERMETHOD_FLATTEN);
$imagick->setFormat($this->determineOutputFormat($pathToImage));
return $imagick;
Could anyone give me an idea?

I am trying to resize a pdf (which i converted from image), and I am trying to resize (increase) the image in its ratio.
$imagick = new \Imagick();
$imagick->readImage($path);
$imagick->resizeImage(595,842,\Imagick::FILTER_CUBIC, 1, true);
// and this:
// $imagick->adaptiveResizeImage(595,842, true);
$imagick->setImageFormat('pdf');
$imagick->writeImage($endpath);
But the image is getting blurry. However, it's not a bad quality image and the image can go that size without getting disturbed. (For example, if I let Twilio to do it (via fax api), the same image can get to that scale).
I have also tried with putting blur parameter of resizeImage between '1' and '0.1'
Original pdf (you can also see it here, if you want to try):
My resized pdf (with blur 1):
My "adaptive resized" pdf:
You are starting with a very small pdf if rasterized and enlarging. So that would cause blurring. But if you increase the input density, it works fine for me in ImageMagick as
convert -density 600 input.pdf -resize 595x842 result.png
I do not know Imagick well, but try the following. Reduce the blur value in resizeImage as desired to make it sharper.
$imagick = new \Imagick();
$imagick->readImage($path);
$imagick->Imagick::setImageResolution( 600, 600 );
$imagick->resizeImage(595,842,\Imagick::FILTER_CATROM, 1, true);
$imagick->setImageFormat('pdf');
$imagick->writeImage($endpath);
I am currently converting a PDF to a set of images using ImageMagick like this..
// create Imagick object
$imagick = new Imagick();
// Reads image from PDF
$imagick->readImage('book.pdf');
// Writes an image
$imagick->writeImages('converted.jpg', false);
The resulting images are quite small, is there a way to set a defined width and then let the height work itself out?
I am trying to convert eps to png image using imagick.This is the code i am using.
$path = getcwd().'/uploads/1488/791/586/imprint_option_1A.eps';
$save_path = getcwd().'/uploads/1488/791/586/imprint_option_2E_c.png';
$image = new Imagick();
$image->readimage($path);
$image->setBackgroundColor(new ImagickPixel('transparent'));
$image->setResolution(300,300);
$image->scaleImage(600, 270);
$image->setImageFormat("png");
$image->writeImage($save_path);
but the transparency is not working i got image with white background ( Result image ). and when we scale image it loses clarity..
Any idea ?
Here is my eps file https://drive.google.com/open?id=0Bwq4DvGGbHVfT0FYTE94WW5GTnc
The function setResolution should be called before reading the image. Thus
$image = new Imagick();
$image->setResolution(1200, 1200);
$image->readImage($path);
should do it. As for the transparency, can you try to get the input as sRGB instead of CMYK? If I convert first the input file to pdf with epstopdf and then use this converted file in the PHP script, it produces a transparent PNG file.
I want to convert SVG images to PNG files with transparent background. I am using below code to convert it using imagick in php,but it gives image with black background.
$image = new imagick();
//set transparent background
$image->setBackgroundColor(new ImagickPixel('transparent'));
$image->setFormat('svg');
$image->readImageBlob(file_get_contents("image.svg"));
$image->setImageFormat("png32");
$image->resizeImage(265,195, Imagick::FILTER_LANCZOS, 1);
$image->writeImage('result.png');
Can anyone please help me how to convert above svg image to png image using PHP.
Any help would be appreciated.
I have a problem creating thumbnails with PHP and imagick. The code is working ok and the thumbnail is generated in the correct size etc but when I try to place a PDF logo on the thumbnail it turns half transparent. I guess it has something to do with the PDF file being generated in InDesign and it probably doesn't have any background defined. Has anyone come across this problem or has an idea what to do about it? I tried to put a white canvas in the background but that didn't help. I also specified a channel for the compositeImage function but that didn't help either.
This is the PDF file I'm having issues with: https://dl.dropbox.com/u/13712643/Case_Study.pdf
The generated Thumbnail looks like this:

The code I have produced so far: http:// pastebin.com/74CYC972
Any ideas? Thank you for your help.
I had the same issue and I solved it by using Imagick::compositeImage that was found in here: php imagick convert PNG to jpg
The code goes something like this:
$im = new Imagick();
$im->readimage($pdfFile."[$currentPage]");
$res = $im->getimageresolution();
$bg = new Imagick();
$bg->setresolution($res["x"],$res["y"]); //setting the same image resolution
//create a white background image with the same width and height
$bg->newimage($im->getimagewidth(), $im->getimageheight(), 'white');
$bg->compositeimage($im, Imagick::COMPOSITE_OVER, 0, 0); //merging both images
$bg->setimageformat("png");
//then you can write to a file
$bg->writeImage('white-background-pdf-image.png');
//or output it
header('Content-type: image/png');
echo $bg;
May be this what you are looking for :
$im->setBackgroundColor(new ImagickPixel('transparent'));
http://www.php.net/manual/en/imagick.setbackgroundcolor.php
None of the existing answers worked for me. Flatten the image just after creating a new imagick() worked instead:
$im = $im->flattenImages();
Edit: The flattenImages method has been deprecated & removed. Use
$im = $im->mergeImageLayers( imagick::LAYERMETHOD_FLATTEN );
