I have an image that is much larger than my form… I want to scale it so that it is always the size of the form no matter what.
I tried…


But that failed…. so how can I resize it? I didn't see anything in the properties like "Stretch" or "Tile"… unless I blatantly missed it.
I also have textures like graph paper that I use in my web pages… it would be nice to tile them as a form background.

I would be happy to just tell it to center the image… but I can't seem to do anything other than specify which image to use.

I would think it could be installed here…

How?

Well, …why not ?

Exemplum:

<COLOR color="#BF0000">unknown symbol 'stretch' in class 'picture' in FMain:7.</COLOR>

The ".Stretch()" Method exists since version 3.16:

   /comp/gb.qt4/picture/stretch - Gambas Documentation

This says Version 3.12.2 so I will see if i can update it.

→ I went to the synaptic package manager… I did not see any versions beyond what i already have.

Thanks,

Hi Jerry, what distro are you using?

 I'm not really sure… it is that latest package that was installed to this desktop from LinuxCNC as i was going to use this machine for CNC control.
I am developing my GAMBAS skills here… then I will migrate to the Raspberry Pi B3+ as I have several and will be building some teaching devices such as the Wind Tunnel project that I have been learning graphics for. I've created quite the GUI already.

My Raspberry Pi also appears to be running 3.12.2 so I will need to stick with that as my YouTube viewers will likely get the sme version and the software I create must work on all the platforms. In the Raspberry Pi I am also using piGPIO to control things such as motors, steppers, servos, etc.

Not sure how to find the distro… not like I can find an "ABOUT" button to click.

On your main computer I think you are running a Debian distribution. If you open Terminal and type lsb_release -a I suspect you will be told you are running Debian buster. I may be wrong!

Debian buster has Gambas 3.12.2 in its repos.

I have just uploaded the latest recommended Raspbian OS (32 bit) on my pi 4, it is now based on Debian bullseye. Gambas 3.15.2 is in the repo.

Image.Stretch() is a valid command in 3.15.2

Not sure if that helps, but that's what I have discovered so far.

I found an easy work around, I just set an image box on the form, place the picture into it with "STRETCH" set to "TRUE".
Then, I set it to be the same size as the background form… for what I'm doing… it works a charm.
