imagick

I'm creating thumbnails for a Digital asset manager, what is the best way to do this with imagemagick? is there good resource out there? I solved it and will share with the WORLD! it will convert .ai, .psd, .jpg, .png, .gif into thumbnails. Here is a function that takes 4 params: $dir - directory to save to. $tmpName - the name to name the file excluding the extension. $fileType - self explanatory. $size - Large or small. function thumbGenerator($dir,$tmpName,$fileType,$size){ $saveFileType = "png"; $imagePath = $dir.$tmpName.".".$fileType; $image = new Imagick(); $image->readimage($imagePath)

I'm using Imagick and like to scale an image to a maximum file size of 2.5MB I had a look to this SOF question: ImageMagick: scale JPEG image with a maximum file-size which is exactly what I want to do but the extent() method from Imagick does not have the size parameter: http://www.php.net/manual/en/imagick.extentimage.php Anyone knows how I could to it? At the moment I'm trying to calculate a coefficient between the original file size and the target file size to calculate a new resolution but found out that the resolution is not proportional to the file size. Update - The output format is

I have a php script that renders an image (with imagick) and saves it to some directory "SITE_ROOT.$filePath" , then does a header('Location: ' . SITE_ROOT.$filePath) , the file it redirects to is a png image. If I go to the path directly, like just type it in the URL bar I can save the image and everything works fine, however when I rely on the script to redirect me and I try to right click and save the image it doesn't recognise that I'm actually trying to save an image, it thinks I'm trying to save it as a non-typed file called 'Driver' which is the name of the script page. I have no idea

How do I efficiently compress a PNG? In my case, the images are small grayscale images with transparency. Currently I'm playing with this: // ... $im->setImageFormat('png'); $im->setImageColorspace(\Imagick::COLORSPACE_GRAY); $im->setImageCompression(\Imagick::COMPRESSION_LZW); $im->setImageCompressionQuality(9); $im->stripImage(); $im->writeImage($url_t); As Imagick doesn't offer COMPRESSION_PNG , I've tried LZW but there's almost no change in the filesize (usually it's even bigger than before). If I open the image in GIMP and simply save it, the filesize gets drastically reduced (e.g. 11,341

I am Having PNG Image And Trying To Flop (Mirror) by imagick function of php It Gets Flop Exactly But The Base Image is In Format 24 Bit RGB and after Convertion It Gets To 8 Bit Pallated . So the Main Problem is that when I use to place both images in my pdflib pages one of the image(converted) displays curly.... Original Image Output After Flop(Mirror) by Imagick and Rendered in PDFlib -> My Code Is Simple ----> $im = new Imagick($background_image); $im->flopImage(); $im->writeimage($background_image."_flop.png"); Modified Date => 29 Oct 2013 Original Image -> Size 4.68 KB Bit Depth 32

I need to change all uploaded files to 72 dpi. I'm using the php imagick extension. heres what i've tried (the image i'm using is 300dpi): $image = new Imagick(); $image->setResolution(72,72) ; $image->readImage($img); $image->resampleImage (72,72,imagick::FILTER_UNDEFINED,1); $image->writeImage($target) this doesn't seem to anything. the image is uploading, but stays at 300dpi MatTheCat's answer is spot on. You might also try setImageUnits() to ensure it's working with inches and not centimeters. $image->setImageUnits(imagick::RESOLUTION_PIXELSPERINCH); $image->setImageResolution(72,72);

I try to recreate a script that uses the ImageMagick command "convert" to compose an image. But I want to do the same in PHP using Imagick (version 6.6.2-10). The command is as follows: convert A1.mpc A3.mpc A4.mpc -channel rgba -alpha on -virtual-pixel background -background none -define compose:args=312x26.6776 -compose displace -composite out.mpc I found out that the parameters stand for the following: convert {background} {overlay} [{mask}] [-compose {method}] -composite {result} The PHP Imagick gives me a compose method, but without a mask parameter: http://www.php.net/manual/en/imagick
