imagemagick-convert

So I have an image upload script. It uploads the image and saves it to the space on the server. What I can't seem to get my head around is say, when the user uploads a .png, by the time it saves on my server i want it to be a jpg. Can anyone help with this, and please don't just direct me to another question as I havent had anything work yet. Here is an example of my code. $name = addslashes($_FILES['image']['name']); $ext = pathinfo($_FILES['image']['name'], PATHINFO_EXTENSION); $size = $_FILES['image']['size']; $temp = $_FILES ['image']['tmp_name']; $error = $_FILES ['image']['error']; if (

I am trying to rasterize some fonts using imagemagick with this command which works fine from a terminal: convert -size 30x40 xc:white -fill white -fill black -font "fonts\Helvetica Regular.ttf" -pointsize 40 -gravity South -draw "text 0,0 'O'" draw_text.gif Running the same command using subprocess to automate it does not work: try: cmd= ['convert','-size','30x40','xc:white','-fill','white','-fill','black','-font','fonts\Helvetica Regular.ttf','-pointsize','40','-gravity','South','-draw',"text 0,0 'O'",'draw_text.gif'] #print(cmd) subprocess.check_output(cmd,shell=True,stderr=subprocess

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

I have a library of large images (8000x6000px ~13mb) for which I would like to generate multiple thumbnails of smaller sizes with widths of 3000px, 2000px, 1000px, 500px, 250px, and 100px. The source image is stored in a flat file, and the generated thumbnails will also be stored in flat files. I've been thinking about the optimal way to do this in Python, and these are potential issues that immediately come to mind: Would it make sense to generate each thumbnail from source image, or can I create the smaller thumbnails from any thumbnail that is slightly larger? E.g., 8000px -> 3000px, 3000px

I have 2 GIFs that are the same length. I want to put the GIFs beside each other to have 1 GIF with both playing at the same time. I have tried to use the convert tool with: convert +append 1.gif1 2.gif output.gif However, this seems to blend all the images together and changes the size to be extremely small. I was thinking that I could append each image together and then create a GIF out of those already combined images. However it did not work when I tried: convert -delay 15 -loop 0 1*.png 2*.png +append output.gif I have a lot of images with long names and I do not want to have to go
