file conversiongraphicssipsterminal
The terminal command sips -s format pict /path/to/image.ext --out /path/to/output.pic ouputs Error: Unsupported output format com.apple.pict even though if you do man sips and go down to format, there is written that it supports jpeg | tiff | png | gif | jp2 | pict | bmp | qtif | psd | sgi | tga.
Is this normal and can you fix it anyway?
Here is a bash script to check the size before :
#!/bin/bash
#theFile given in input
theFile=$1
#using sips to retrieve the width & height
size=($(sips -g pixelWidth -g pixelHeight theFile | grep -o '[0-9]*$'))
#the size you want
width=315
height=300
if [[ ${size[0]} -eq $width && ${size[1]} -eq $height ]]; then
#put here your command for files that are 315*300
fi
I do not believe you can do that with sips. I would recommend ImageMagick which you can easily install using Homebrew. Then the command is:
convert InputImage.jpg -background blue -splice 0x100 PaddedResult.jpg
If you want to add transparent padding, use:
convert InputImage.jpg -background transparent -splice 0x100 out.png
If you want to composite two images together, you can do this:
convert -size 1024x768 xc:blue 1024x768.jpg # create big blue image
convert -size 100x100 xc:red 100x100.jpg # create little red image
composite -gravity northeast 100x100.jpg 1024x768.jpg out.jpg # superimpose top right
Note that I am creating my images first, you can obviously just use your own.

Not the definitive answer but be careful with sips. It seems to me sips itself has been updated but the man page remained the same. On my Mac PICT creates no output at all and PSD creates a file that is totally garbled when viewed in Photoshop. It seems you can also export to PDF, and the result opens just fine in Adobe Acrobat, but when opened in Photoshop or Illustrator what you see is very, very different of what should be there ...
