How to use Imagick to merge and mask images?

由 点点圈 提交于 2019-11-27 10:41:59
I know very little of image processing and even less of the terminology used, so please bear with me. Basically, I want to merge two images together where one of them will act as a mask. That image looks something like this: Where the blue and yellow background are both transparent in reality. This image is being used as a mask for regular photo's. Parts of the photo that 'stick out' of the circle need to be 'cropped' (be made invisible) while the inside remains visible. So everything that comes in the blue area is invisible, everything in the yellow area is visible. I honestly have no clue

Running ImageMagick on XAMPP 1.8.3 with Windows 7

由 大城市里の小女人 提交于 2019-11-27 08:03:32
I have been trying for hours to get ImageMagick working on my localhost (running XAMPP 1.8.3 on Windows 7). I have checked and tried literally every solution that I can find on this website, and dozens of others. Nothing works. No matter what combination of ImageMagick builds and imagick DLLs I try, I always get some kind of "can't find dll" error when I try to start Apache (the specific message varies based on what combination I'm trying, but it's always some sort of missing DLL message). Can anyone just give me a (moderately recent) combination of XAMPP/ImageMagick/Imagick that works? Chris

How to remove exif from a JPG without losing image quality?

由 穿精又带淫゛_ 提交于 2019-11-26 23:03:01
问题 I have a PHP photo sharing application in which user-uploaded images are resized into various thumb formats using ImageMagick. As a seemingly "smart" way to save on file size, I am stripping exif info from these thumbs as follow: $imagick = new Imagick($image); $imagick->stripImage(); $imagick->writeImage($image); This works. It does remove the EXIF info, where a thumbs of 30KB saves 12KB and becomes 18KB. A significant saving when showing many of such thumbs on a single page. The problem
