You can use the trimImage function to trim the image, and then look at the geometry and page info to find how the bounding box of the image that was left after trimming. $base = new Imagick(realpath('./trim.png')); $base->trimImage(0); $geometry = $base->getImageGeometry(); $pageInfo = $base->getImagePage(); printf ( "Width %d Height %d\n", $geometry['width'], $geometry['height'] ); printf( "OffsetX: %d

问题 I have trying hard, but can't make this method works properly. The usage format is Imagick::levelImage ( float $blackPoint , float $gamma , float $whitePoint [, int $channel = Imagick::CHANNEL_ALL ] ); I try use it like $img->levelImage (0, 1.0, 255); and $img->levelImage (255, 1.0, 0); or even like $img->levelImage (-0.5, 1.0, 5.6); but without any success.

I cant save some facebook images to my server as it does not understand the file

由 喜你入骨 提交于 2019-12-01 14:39:40
I am using the facebook graph api and it was working well until I realised that some of the jpg files have a query string at the end that is making them unusable. e.g. https://scontent.xx.fbcdn.net/hphotos-xaf1/v/t1.0-9/487872_451835128174833_1613257199_n.jpg?oh=621bed79f5436e81c3e219c86db8f0d9&oe=560F3D0D I have tried stripping off everything after .jpg in the hope that it would still load the image but unfortunately it doesnt. In the following code take the $facebook_image_url to be the one above. This works fine when the url ends in .jpg but fails on the above. As a note, I am converting

imagick | Gradient map

由 丶灬走出姿态 提交于 2019-12-01 11:30:30
问题 I'm trying to get this effect on images using imagick. In photoshop it's called a gradient-map, but I can't find anything similar to this in imagick. I think I need to make it black-and-white first, but I don't get how to add the colors after doing so. Hope you can help! Thanks --- EDIT: --- I'm using Imagick , not imagemagick. Notice there are two colors in the image, it's not just colorized. Dark blue for the darker colors, and light green/aqua for the lighter ones. 回答1: PHP Imagick Version

Use two different fonts in imagemagick on one line

由 眉间皱痕 提交于 2019-12-01 01:08:19
So i want to draw on my image text lets say in this example "Trevor, 24" But I want to use the font Helvetica for Trevor, and for 24 i want to use the font Arial. But I want it to be on the same line and look like it's one. Is it possible or how would i go about making it so that even if i change the name and age, that i can print it out like this? "Trevor, (Helvetica) 24(Ariel)" I would assume to print them next to eachother, but if someone enters the name longer than Trevor 24 would go over it. the idea is to make it on the same line What do you guys think? $draw = new ImagickDraw(); $color

Outline a transparent image using imagick PHP

由 我的梦境 提交于 2019-12-01 01:05:40
问题 I have an image with a transparent background that I'd like to outline with a 5px border. In photoshop, I can stroke it to achieve this.

This is what I want to achieve. 回答1: I'll start at the command line and may do the PHP later, or let you work that bit out... Step 1 - Extract transparency As
