(The idea here is that all of the original files are in the Downloads folder, and we create a folder called newfolder to dump the transformed pictures.)Ĭonvert $file -resize 1275x1222 resized- $file Suppose further that the original files are in the Downloads folder. We have a bunch of *.jpg and we save them in a new folder called newfolder. Now, suppose that I want to save them in a completely different directory altogether. And it’s a one-liner! However, in this case, we save all the new files within the same folder as the old files.

The great part about this small piece of code is that it will batch convert as many pictures as you want. But this is not the case when we use the format switch (an exception to the rule). Typically, the distinction between mogrify and convert is that mogrify overwrites the original files.

Here, the format switch prevents the images from being overwritten. We then tell the ImageMagick with the format switch to transform the image into a jpg image. Each operating system is a little different, but in Ubuntu for example, the fonts are located within the /usr/share/fonts directory and contains a list of all available system fonts you may use in the above command.Here, we’re telling the ImageMagick that there are lots of “.png” images to use each one with a “.png” extension. The selection of fonts varies depending on your computer, but all standard fonts that are generally used will be there. There is a huge list of colors available, and if desired you may list all colors supported by your computer with the command: cb:>showrgb Please note, you must be careful with the -draw option, which must begin in single quotes followed by the location of the top left most point, then by the text of the caption surrounded by double quotes.

The above command will place a caption of 'Warm Regards from the Family' onto the source image using the font Helvetica 14pt in yellow, with the top left point of the image starting at 270x160 pixels, and save the results in DEST_FILE. Convert profile.jpg -pointsize 14 -font helvetica -fill yellow -draw 'text 270,160 'Warm Regards from the Family' ' profile_cap.jpg
