[SOLVED] Command to resize png images

[Argolance]

Hello!
This Linux/Unix 'convert' command exists but seems not to be present on Puppy! I need it to resize png images inside a script...
Thank you for your attention.

Regards.

That is part of the ImageMagick package. You can get it with the Puppy Package Manager, from an Ubuntu repository, I think.

Pwidgets uses resizepng

Hello,
Thanks for replying.

I finally found something in Puppy but the command seems to be part of Pwidget by zigbert!

'/usr/bin/resizepng'

Code: Select all

resizepng in.png out.png w h x

• - w (width): number of pixels
  - h (height): number of pixels
  - x, don't know exactly what is this number used for but if not present, command doesn't work and console sends a segmentation error... Any number different from 0 seems working... This has to be cleared up though!

Regards.

Hello Zigbert!
Please, may I ask you what is the third number used for?
Thanks a lot.

Dear Argolance,

You could try my picscale: http://www.murga-linux.com/puppy/viewtopic.php?t=72183, which can handle a variety of file types, the alpha channel (transparency) and is small. Barry has included it in later puppies too:) http://bkhome.org/blog/?viewDetailed=02375.

With kind regards,

Great!
Thank you.

Without looking into it (ages since I used it), it sounds logical that the third number sets quality/compression.
