Adjust Image Size in One Go
Here’s how to quickly generate various sizes of icons and splash images needed for iPhone and Android app development.
The sizes mentioned are specific to FireMonkey, so please adjust the numbers for other environments as needed.
I accidentally lost the program I had previously created, so I had to do this in a hurry… 😢
2. Batch file to generate splash images
gm convert -resize "320x480^" -gravity center -crop "320x480+0+0" "%1" splash_320x480.png
gm convert -resize "426x320^" -gravity center -crop "426x320+0+0" "%1" splash_426x320.png
gm convert -resize "470x320^" -gravity center -crop "470x320+0+0" "%1" splash_426x320.png
gm convert -resize "640x480^" -gravity center -crop "640x480+0+0" "%1" splash_426x320.png
gm convert -resize "640x960^" -gravity center -crop "640x960+0+0" "%1" splash_640x960.png
gm convert -resize "640x1136^" -gravity center -crop "640x1136+0+0" "%1" splash_640x1136.png
gm convert -resize "750x1334^" -gravity center -crop "750x1334+0+0" "%1" splash_750x1334.png
gm convert -resize "960x720^" -gravity center -crop "960x720+0+0" "%1" splash_426x320.png
gm convert -resize "1125x2436^" -gravity center -crop "1125x2436+0+0" "%1" splash_1125x2436.png
gm convert -resize "2436x1125^" -gravity center -crop "2436x1125+0+0" "%1" splash_2436x1125.png
3. Batch file to generate icons
gm convert -resize "36x36^" -gravity center -crop "36x36+0+0" "%1" icon_36x36.png

gm convert -resize "120x120^" -gravity center -crop "120x120+0+0" "%1" icon_120x120.png
gm convert -resize "144x144^" -gravity center -crop "144x144+0+0" "%1" icon_144x144.png
gm convert -resize "180x180^" -gravity center -crop "180x180+0+0" "%1" icon_180x180.png
