ImageMagick

问题 I am having image1.jpg with the size of 350x500 and another image2.png ( 350x150 ) with gradient effects like shadow. I need to apply the shadow to image1.jpg in its bottom. But geometry doesn't work for me. convert -extent 600x700\! image1.jpg \( image2.png -geometry +0+500 \) -composite final.png I hope the geometry will position an image at the point I have given, If I am right, geometry is not working for me. 回答1: Not certain what you are trying to achieve, but is this close: convert xc

问题 I have used convert this to draw a rectangle on image now i want to undo this the how? help? convert Image1.jpg -fill black -draw "rectangle 135,55 155,60" Image2.jpg 回答1: Once you draw a rectangle onto an image, it has replace the pixels in the image with the color of rectangle. You cannot undo that. You can replace the color of the rectangle with some interpretation of the image pixels nearby using morphology techniques in Imagemagick by making a mask from the same rectangle and using that

问题 I am rather new to using the command line and php. That being said I have been trying to figure out how to use ImageMagick with the exec() function. I have this currently, $command="/usr/local/lib/ImageMagick convert images/a.pdf images/a.png"; if(exec($command)){ echo 'yes'; } else{ echo 'no'; } Which is returning 'no'. I believe I am missing something about how to execute convert from the correct directory. Is my $command set up properly? (I was given the path to ImageMagick from my web

问题 I'd like to place a watermark diagonally over a number of pictures. The width and length of these pictures differ and some might even be smaller than the watermark itself. This will be used inside a script, in which the user can choose from different options like "horizontal", "vertical", "diagonal" or specify an angle by himself/herself. Therefore I need to calculate the rotation angle. The angle should rotate the watermark, so that it is diagonally positioned over the underlying image.

问题 So, I have this background image: And I have a 1px x 1px image that I want to overlay on that. If I run: convert bg.png \( -size 80x240 -background none -rotate 30 -geometry +120+88 tile:red.png \) -composite result.png I get this: But I want to rotate it with fixed center. The expected result should be something like this: Do you know how can I accomplish that? Thank you. 回答1: Looking into the comment by @frostyterrier I think his problem is he needs +distort and is using -distort? This page

问题 I'm using the following code to create a pdf from a jpg image: $im = new Imagick(); $im->readImage('./image.jpg'); $im->setImageFormat('pdf'); $im->writeImage('../images/pdf/image.pdf'); Now I recently Saw that google indexed the image.pdf file but as the title on the google search page it says "Untitled" instead of "Image" cause the name was image.pdf. So to me it appears as if PDF had it's own naming which has been left out in my code. How can I change that "Untitled" to the actual title

问题 I have this code but I would like to edit it so the exported file name is the same as the file name used to make it mogrify -composite -gravity center ~/Desktop/civmap-client-master/data/watermark.png ~/Desktop/civmap-client-master/data/nowm/*.png ~/Desktop/civmap-client-master/data/wm/*.png It just throws an error when I used *.png as my exported file name.

问题 I have a website that generates polaroid-like images stacked on eachother at different angles. Up until now everything worked well, but now i've started getting some black background around my transparent .png's. You can see the problem here. The images in the last album are all messed up. I'm using imagemagick (6.5.4.7-3.fc12). my commands look something like this: the first one is contained whitin a foreach and generates a bunch of pngs rotated at different angles convert '{$sf}' -auto

问题 What is the most direct way to draw a pie chart using ImageMagick in an existing image. For example, how would I draw a single slice given the following inputs? A center point (x,y) Radius Percent 回答1: Create your pie wedge using SVG; I got my example from here: <svg> <path d="M200,200 L200,20 A180,180 0 0,1 377,231 z" style="fill:#ff0000; fill-opacity: 1; stroke:black; stroke-width: 1"/> </svg> Then, overlay that image using ImageMagick to your background image. composite.exe -background
