Multiply Image by 6 and export

Hello Imagemagick professionals,

I need to convert images of winebottles. I have a jpg image of the bottles, all same height but different width (according to the bottlesize).

The image of the bottle has to be resized, multiplied by 6 (or 3) and pasted in a new image of a rectangular size (e.g. 1000 x 1000). So the original image contains one bottle, the resulting image contains 6 (or 3) similar bottles of the original.

I need a script, that converts every image in a specific folder with this procedure.

Can somebody provide help with that? Offers for that would be very appreciated. /* To the admins - I am willing to pay for it */

Thanks in advance and kind regards

What version of IM, on what platform?

You need to resize, but to what size? The same size for all images, or is there some rule for the new size?

Perhaps sample input and output images would help.

Hi snibgo,

thanks for the reply. I installed the program today via Homebrew on a Mac, so I guess it's the current version, but I am not familiar with the software at all. I am just a "normal" user with little command line knowledge.

The pictures all have the same height of 800px. The width is different depending on the bottle.

Example for 6 bottles:
Original file wine1:
Result file wine1:

Original file wine2:
Result file wine2:

Example for 3 bottles:
Result wine2:

A process should look something like this:


1. open the original file
2. scale it to [canvasSize/numberOfBottles] width (=166px)
3. generate a canvas of [canvasSizexcanvasSize] (=1000x1000px)
4. paste [numberOfBottles] in one line on the canvas
5. save resulting picture under filename [numberOfBottles]+"x"+originalFilname.jpg in a designated folder

This process should apply to all pictures in a specific folder. A script for another number of bottles should do the same accordingly. I basically need this script for 3 and 6 bottles.

Hope I could clarify a little. Please don't hesitate to ask any questions or if everything is clear send me an offer. I would prefer to pay via Paypal.

Thanks in advance

What version of ImageMagick did you install?

On IM6 on command line type

Code: Select all

convert -version
On IM7 type

Code: Select all

magick -version

How much space should be put between the bottles? Can you quantify that in percent of width of the image or pixels? Or should it just use whatever space you provide.

The simple command would be something like

Code: Select all

convert "$file" -duplicate $dups +append -resize 1000x1000 -background white -gravity center -extent 1000x1000 "${output_directory}/${number}x${file}"
I have to go out for a while but I will work on this later today. I presume you want a shell script or do you need an AppleScript?

Please send me private mail on this system with your actual email address so that I may contact you directly and send the script. No charge, since I think it is very simple.

Are all the input images JPG? If not, what other formats does the script have to process?
