Convert images which have the same names but different extensions

阅读更多关于 Convert images which have the same names but different extensions

问题 For example, I have two files: aaa.jpg (with cat) aaa.png (with dog) As you can see, images are different, despite of their names, which are the same. I want to convert both these images to one single format. The basic attempt for this task is mogrify -format jpg *.png But it doesn't work, for obvious reasons (one folder cannot contain multiple files with the same name and extension). Also, some notes from myself. Please note, this is just example. In real life, it would be about 100-200

问题 First i took lena512color.tiff amd converted it to jpg and then i ran mogrify on it with a quality of 90%.Surprising after i decrease the quality filesize is higher.What am I doing wrong here ? gm convert lena512color.tiff lena512color.jpg # filesize = 37,043 gm mogrify -quality 90 lena512color.jpg # filesize = 58,132 回答1: By default, the output quality is set to whatever GraphicsMagick thinks the quality of the input file is. So I guess it thinks the TIFF's quality is lower than 90 and you

问题 I am working on creating a video timelapse. All the photos I took are .jpg images shot at 4:3 aspect ratio. 2592x1944 resolution. I want them all to be 16:9 at 1920x1080. I have written a little script to do this, but the process is not very fast. It took about 17 minutes for me to crop and resize 750 images. I have a total of about 300,000 to deal with, and will probably be doing then in batches of about 50,000. That is 18 hours 45 minutes per batch, and over 4.5 days of computing total. So
