B4J Question Help to modify png size

[Pablo Torres]

Hi, I have a .PNG file whose sizes are 624 and 245, I need to create another file, with the same image, whose sizes should be 312 and 122 (exact half for both large and wide)
I have to do this Without UI, so it should be in a NON-UI jar.
Can anyone help me? Please

many thanks for your time

You can create a UI project that doesn't show any form.

But will depend on openjfx, right?
That won’t help, I tried to install openjfx on the server but couldn’t do it, I don’t know why

You can find Linux Java with JavaFX here: https://www.b4x.com/android/forum/t...the-simplest-way-to-distribute-ui-apps.99835/

Though if it is a server solution (jServer) then you must create a non-ui project.

You can use a tool such as ImageMagick and run it with jShell.
