I installed Yii and Imagine with composer and tried to use imagine.
the issue is when i try to use this code from the imagine website introduction i got an error 500 :
Argument 2 passed to Imagine\Gd\Imagine::create() must be an instance of Imagine\Image\Color, instance of Imagine\Image\Palette\Color\RGB given
code:
use Imagine\Image\Box;
$imagine = new Imagine\Gd\Imagine();
$palette = new Imagine\Image\Palette\RGB();
$size = new Box(400, 300);
$color = $palette->color('#000', 100);
$image = $imagine->create($size, $color);
$image->save('images/test.png');
when i edit this line :
$image = $imagine->create($size, $color);
with
$image = $imagine->create($size);
the picture is created white so i guess Imagine is working
Did i miss something ? Do i have to change something in the config or something else ?
Any idea will be much appreciated
Thanks

I found this nice code :
https://phpimagick.com/Tutorial/backgroundMasking
But I get the same picture without checkerboard. Something is wrong in my config or in the code ?
My best working code is :
$BackgroundColor = "rgb(255, 255, 255)";
$img = new Imagick();
$img->readImage('xxxxx.jpg');
$img->setImageFormat('png');
$fuzz = Imagick::getQuantum() * 0.1; // 10%
$img->transparentPaintImage($BackgroundColor,0,$fuzz,false);
$img->writeImage('xxxx.png');
But without blur and mask :(
Any idea ?
maybe there is a better way but just remove this line works for me :)
$mask->setImageAlphaChannel(\Imagick::ALPHACHANNEL_DEACTIVATE);
It's driving me insane.. Just searched for hours to find a solution. But nothing really found. So hopefully anyone can help me.
I'm trying to create an customized image on the fly. I use this to create the images: https://github.com/Treinetic/ImageArtist
Everything works fine except the font. This is the snippet from the class:
$im = new \Imagick();
$background = new \ImagickPixel('none');
$im->setBackgroundColor($background);
$im->setFont($font->getPath());
$im->setPointSize($writer->getSize() * (0.75));
$im->setGravity(\Imagick::GRAVITY_EAST); //later we will have to change this
$width = $writer->getWidth();
$height = $writer->getHeight();
$text = $writer->getText();
$margin = $writer->getMargin();
$im->newPseudoImage($width, $height, "pango:" . $text );
$clut = new \Imagick();
$clut->newImage(2, 2, new \ImagickPixel($color->toString()));
$im->clutImage($clut);
$clut->destroy();
$im->setImageFormat("png");
$image = imagecreatefromstring($im->getImageBlob());
$template = $this->imageHelper->createTransparentTemplate($width+ (2*$margin),$height+ (2 *$margin));
$img = new Image($template);
$text = new Image($image);
imagedestroy($image);
imagedestroy($template);
return $img->merge($text,$margin,$margin);
The $font-getPath(); looks correct and echo /var/www/vhosts/example.com/dev-test/ImageArtist/src/lib/AssetManager/../../resources/Fonts/Gotham-Light.ttf
This is the full code
use Treinetic\ImageArtist\lib\PolygonShape;
use Treinetic\ImageArtist\lib\Text\TextBox;
use Treinetic\ImageArtist\lib\Text\Color;
use Treinetic\ImageArtist\lib\Text\Font;
use Treinetic\ImageArtist\lib\Overlays\Overlay;
use Treinetic\ImageArtist\lib\Image;
require('../vendor/autoload.php');
$main_image = new Image("ranks/main-image.png");
$textBox = new TextBox(720,40);
$textBox->setColor(new Color(0,0,0, 125));
$textBox->setFont(Font::getFont('./Gotham-Light.ttf'));
$textBox->setSize(42);
$textBox->setMargin(0);
$textBox->setText($_GET["name"]);
$main_image->setTextBox($textBox, 40, 620);
$main_image->save("./newImage.png",IMAGETYPE_PNG);
But the font specified is not used by Imagick. If i try to create an image from den command line via
convert -font /var/www/vhosts/example.com/dev-test/ImageArtist/src/lib/AssetManager/../../resources/Fonts/Gotham-Light.ttf -pointsize 72 label:Test test.gif
And... The Font is used on command line created image :/ The font file is reachable and readable via php but not used via Imagick ....
Does anyone has an idea why php imagick can't use my font but convert -font can?
The script is running on PHP-FPM 7.0.23 on an dedicated root server with nginx as an RPS.
Hope you can help me out.. It really drives me crazy :)
Thanks

SOLVED
Found out that $im->newPseudoImage($width, $height, "pango:" . $text ); cause the issue. Switching to $im->newPseudoImage($width, $height, "caption:" . $text ); and everything works fine.
I want download an image from AWS S3 and process it with php. I am using "imagecreatefromjpeg" and "getimagesize" to process my image but it seem that
Storage::disk('s3')->get(imageUrlonS3);
retrieve the image in binary and is giving me errors. This is my code:
function createSlices($imagePath) {
//create transform driver object
$im = imagecreatefromjpeg($imagePath);
$sizeArray = getimagesize($imagePath);
//Set the Image dimensions
$imageWidth = $sizeArray[0];
$imageHeight = $sizeArray[1];
//See how many zoom levels are required for the width and height
$widthLog = ceil(log($imageWidth/256,2));
$heightLog = ceil(log($imageHeight/256,2));
//more code here to slice the image
.
.
.
.
}
// ex: https://s3-us-west-2.amazonaws.com/bucketname/image.jpg
$content = Storage::disk('s3')->get(imageUrlonS3);
createSlices($content);
What am I missing here ?
Thanks
I think you are right in your question what the problem is - the get method returns the source of the image of itself, not the location of the image. When you pass that to createSlices, you're passing the binary data, not its file path. Inside of createSlices you call imagecreatefromjpeg, which expects a file path, not the image itself.
If this indeed the case, you should be able to use createimagefromstring instead of createimagefromjpeg and getimagesizefromstring instead of getimagesize. The functions createimagefromstring and getimagesizefromstring each expects the binary string of the image, which I believe is what you have.
Here's the relevant documentation:
createimagefromstring - http://php.net/manual/en/function.imagecreatefromstring.php
getimagesizefromstring - http://php.net/manual/en/function.getimagesizefromstring.php
Resulting code might look something like this:
function createSlices($imageData) {
$im = imagecreatefromstring($imageData);
$sizeArray = getimagesizefromstring($imageData);
//Everything else can probably be the same
.
.
.
.
}
$contents = Storage::disk('s3')->get($imageUrlOnS3);
createSlices($contents);
Please note I haven't tested this, but I believe from what I can see in your question and what I read in the documentation that this might just do it.
I'm converting PDFs to JPEGs and I can't get setImageScene to work.
I've tried calling it before readImage and after readImage. It has no effect on the numbering of the files.
Can someone provide a working example?
Thanks
It doesn't look setImageScene works. It's really easy to number files yourself though.
$imagick = new Imagick("./LayerTest.psd");
$pageNumber = 200;
foreach ($imagick as $subImage) {
$filename = "./output_$pageNumber.png";
$subImage->setImageFormat('png');
$subImage->writeImage($filename);
$pageNumber++;
}
Loads of answers on how to do it for a command line
convert /path/to/file/file.pdf[3] output.jpg
great... but what if I am using in memory processing, I am generating PDF with PDFlib and then output its buffer to a function that I want to generate jpg preview of selected page. How? My code :
[...]
$buf = $pdf->get_buffer();
//$buff is just a PDF stored in a string now.
$im = new Imagick();
$im->readimageblob($buf);
$im->setImageFormat("jpg");
$im->setimagecompressionquality(60);
$len = strlen($im);
header("Content-type: image/jpeg");
header("Content-Length: $len");
header("Content-Disposition: inline; filename=test.jpg");
echo $im;
This creates a jpeg but always returns last page of the PDF. I want to be able to choose which one will be converted. Is it doable without saving temporary files and using command line (exec('convert /path/to/file/file.pdf[3] output.jpg')) syntax?
Let me add that I tried
$im->readimageblob($buf[2]);
and it did not work :)
For the ones who is still searching for solution of reading specific page number from blob, please check this question Creating array populated by images from a PDF using PHP and ImageMagick
$img_array = array();
$im = new imagick();
$im->setResolution(150,150);
$im->readImageBlob($pdf_in);
$num_pages = $im->getNumberImages();
for($i = 0;$i < $num_pages; $i++)
{
$im->setIteratorIndex($i);
$im->setImageFormat('jpeg');
$img_array[$i] = $im->getImageBlob();
}
$im->destroy();
I'm loading the PDF binary into memory from Amazon S3 and then selecting the specific page I want using setIteratorIndex() followed by getImage()
function get_image_from_pdf($pdf_bytes, $page_num){
$im = new \Imagick();
$im->setResolution(150, 150);
$im->readImageBlob($pdf_bytes);
$im->setIteratorIndex($page_num);
$im = $im->getImage();
$im->setImageFormat('png');
return $im->getImageBlob();
}
version 3.0.1
being on the last image or first image in imagic object
$image_obj = new Imagick("test.pdf"); then you on last image in $image_obj
if you use
fp_pdf = fopen("test.pdf", 'rb');
$image_obj = new Imagick();
$image_obj -> readImageFile($fp_pdf);
then you on the first image in $image_obj
In second case to switch to last image you can do
fp_pdf = fopen("test.pdf", 'rb');
$image_obj = new Imagick();
$image_obj -> readImageFile($fp_pdf,2); // 2 can be any positive number?
then you on the last image in $image_obj
echo $image_obj->getNumberImages() // Returns the number of images in the object
then
if ($image_obj->hadPreviousImage)
$image_obj->previousImage() //Switch to the previous image in the object
}
or
if ($image_obj->hasNextImage()) {
$image_obj->nextImage()) //Switch to the next image in the object
}
e.g. if you have 6 images total and you need 4th then do from the end
$image_obj->previousImage()
$image_obj->previousImage()
$image_obj->setImageFormat("png");
header("Content-Type: image/png");
echo $image_obj;
EDIT: Another find is that you can
foreach($image_obj as $slides) {
echo "<br>".$Obj_img->getImageWidth();
//or wehatever you need to do.
}
EDIT 2: Very simple solution would be to use this function $image_obj->setIteratorIndex(4) count starts with zero.
It's not good news unfortunately, but I can definitively say that, as of time of writing, the ImageMagick (and PHP libraries) don't support the page notation that you're trying to use. (For people from the future finding this: I'm checking php-imagick-3.0.1 and imagemagick-6.6.0.4).
I'm trying to do the exact same thing as you, and I've just spent the last few hours trawling through the source, trying to figure out what it does and how it gets the pages, and it looks like it simply won't use it when reading from a stream (ie. the readBlob() call).
As such, I'm just going to be putting it in a temporary file and reading it from there instead. Not as elegant, but it'll work.
