imageresize后如何获取imagick临时文件的名称

Question

Using imagemagick, I need to resize images of multiple sizes (800px, 400px, 50px).

And I do not want to save these image locally because I need to upload the image to Amazon S3 anyways.

For example, after the following code

$im->resizeImage(0, 800, imagick::FILTER_LANCZOS, 1, FALSE);

$im->getImageFilename() still returns the original temp file uploaded prior to resizing. What I need is the temp file name & path after the resizing so that I can upload it straight to Amazon S3 without doing writeImage() locally. To save time and space.

Any suggestion?

There is no "temp file". ImageMagick does operations in memory. If you want the image to be written out to a file you need to call $im->writeImage .
