PHP - convert EPS to PNG using Imagick - php

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.

Imagick php class not working when I try to set image resolution and color space for a base64 image then saving it in jpg format

I'm trying to generate a high resolution jpg image from base24 image string using imagick php class. the code runs with no errors.
However, the image saved does not show any resolution or color space in photo viewers or browsers. I don't know whether my code is working or not?!
Any help on this is highly appreciated.
$image_data = base64_decode($data);
$imagick = new Imagick();
$imagick->readImageBlob($image_data);
$jpegimagequality = 95;
$imagick->setImageCompression(Imagick::COMPRESSION_JPEG);
$imagick->setImageCompressionQuality($jpegimagequality);
$imagick->setImageResolution(300,300);
$imagick->setImageColorspace(Imagick::COLORSPACE_SRGB);
$imageResampled = $imagick->resampleImage(300, 300, Imagick::FILTER_UNDEFINED, 1);
$imagick->setImageFormat("jpg");

Converting svg to png generates blank image

I have went through a lot of similar questions.i couldn't find an answer to my problem.
I have an svg image. I'm trying to convert it into a png image.
I have been using a 300dpi image as background of svg image.Now i have changed it into 600dpi. After that imagick returns an empty png image.
$svg=path to svg;
$im = new Imagick();
$im->readImageBlob($svg);
$im->setImageFormat("png32");
$im->setImageCompressionQuality(100);
$im->resizeImage(720, 445, imagick::FILTER_LANCZOS, 1);
$base64=base64_encode($im);
$im->clear();
$im->destroy();
return 'data:image/jpg;base64,' . $base64; //returns blank png
What am i missing here? Do i have to include any libraries??
PHP VERSION: 7
IMAGICK VERSION: ImageMagick 6.8.9-9
Looking at the documentation of Imagick::readImageBlob
Reads image from a binary string
this seems not the correct method for reading from a file path.
You should either use Imagick::readImage
Reads image from filename
$im = new Imagick();
$im->readImage($svg);
or the constructor Imagick::__construct
Imagick::__construct ( mixed $files )
Creates an Imagick instance for a specified image or set of images.
$im = new Imagick($svg);

PHP - convert all images to jpg using Imagick - bad quality

I found more topics from this web site about quality with Imagick but nothing help me...
I have to save all images as JPG. I created this script:
$image_url = 'http://limuzynamercedes.pl/wp-content/uploads/2014/06/3.png';
$image_code = file_get_contents($image_url);
$img = new Imagick();
$img -> readImageBlob($image_code);
$img->setResolution(300, 300);
$d = $img->getImageGeometry();
$img->cropImage($d['width'],($d['height']-120), 0,0);
$img->setImageFormat('jpeg');
$img->setImageCompression(imagick::COMPRESSION_JPEG);
$img->setCompressionQuality(100);
$img->writeImage('read.jpg');
$img->clear();
echo '<img src="read.jpg?'.time().'">';exit;
Here is original image: http://limuzynamercedes.pl/wp-content/uploads/2014/06/3.png
and here is image which was converted by my script: http://s5.ifotos.pl/img/demo1jpg_saeaxqx.jpg
Where is a problem? Why this image is always convert in bad quality?
Thanks.
The image is not in "bad quality" (there is no blurry areas found), but the difference between 2 images is caused by transparent PNG to JPG conversion.
Before you crop the image, add these two lines:
// set background to white (Imagick doesn't know how to deal with transparent background if you don't instruct it)
$img->setImageBackgroundColor(new ImagickPixel('white'));
// flattens multiple layers
$img = $img->mergeImageLayers(Imagick::LAYERMETHOD_FLATTEN);

Setting background color as transparent while creating PNG image from EPS file

Im using PHP Imagick to process images, I need to convert an EPS file into PNG file and next the remaining code can process the created PNG, Im able to convert EPS as PNG and can process to, but when i do this the PNG file is creating with white background, I want it to be transparent where EPS file is not having any background either.
My code is as follows
$img = new Imagick();
$img->setResolution(300,300);
$img->readImage('my_file.eps); //reading the file
$img->setBackgroundColor ('#623423'); //setting background color but not working
$img->setImageFormat("png"); //setting the format to save//converting
$img->writeImage('converted.png'); //saving the converted file
But the generated png is coming with white bg, can some one help me how to create it with out BG color(transparent)?
Thanks in advance!.
Have you looked at this example?
<?php
$im = new Imagick();
$im->setBackgroundColor(new ImagickPixel('transparent'));
$im->readImage('carte_Alain2.svg');
$im->setImageFormat("png32");
header('Content-type: image/png');
echo $im;
?>
