Gambas ONE

have had the same problem with picturebox ... picture inverse und form black on black ... problem was solved by creating a new form ...

Hi PJBlack
I already tried that and even a whole new project.
Same - negative - result.

To all : I'll be away for a couple of days.

I also have issues using Image but not using Picture

' Gambas class file
Private MyGraphic As Picture
 
Public Sub Form_Open()

  MyGraphic = Picture.Load(Application.path & "/GB_FLAG.svg") 'or take any other graphic

  PictureBox1.Picture = MyGraphic.Image.Stretch(PictureBox1.W, PictureBox1.H).Picture
  Button1.Picture = MyGraphic.Image.Stretch(Button1.W, Button1.H).Picture

End

There's a big difference between an Image and a Picture that is hard to explain.

I see it like if I have a Picture and I look at it then i have an "Image" of that "Picture" in my head
But the "picture" is the real thing while the "image" is not

Or maybe I can get an "Image" of something in my head and make a "Picture" from it. but the "Image" is not real only the "Picture" is once drawn.

hmm , like i say , it's hard to explain.

Suffice to say , Use the "Picture" property/class for final image rendering and the "Image" property to manipulate (colour/stretch/etc)

Congratulations Bruce! That one needed some thinking over indeed.
There is unfortunately almost nothing to be found on how to use ‘stretch’ in the Gambas documentation, certainly no example code.
Now that the right way of using the ‘stretch’ property has been found, I’d like to explain why I wanted to be able to use vector graphics. I’ll put it in a post in the General section, so perhaps others may benefit.

P.S. I just came across what looks to me like the best Gambas manual till now. It’s in German, but the authors are working on an English translation. Certainly well worth it to pay a visit.
https://gambas-buch.de/dwen/doku.php?id=start. It has some examples on ‘stretch’.

Have a nice weekend.

I was playing with SVG in Gambas and the images look stunning. I can create nice gradients and such that always look nice.
In this example (sent to me) the file pg.svg is loaded and stretched to the size of the picturebox automatically. This works out very well for stationary SVG... but playing around in HTML a long time ago I discovered that if I named something like "pointer" in the drawing... I could then assign it an angular rotation or movement and do all sorts of things with it. I'm wondering now if once an image is loaded... can I somehow manipulate the object? If so... I can make some incredible gauges and displays.

Check these out... steal the code... see what you can do with it... but if you get something to work in Gambas... please share!

Try the code below, then resize the form. I think the PictureBox.Mode command is quite powerful and under used. I wrote the help for it here.

PictureBox1 As PictureBox

Public Sub Form_Open()

  With Me
    .Height = 400
    .Width = 500
    .Padding = 5
    .Arrangement = Arrange.Vertical
    .Center
  End With

  With PictureBox1 = New PictureBox(Me) As "PictureBox1"
    .Expand = True
    .Alignment = Align.Center
    .Mode = PictureBox.Contain
    .Picture = Picture["./pg.svg"]
  End With

End

Public Sub PictureBox1_MouseDown()

  Me.Close()

End

Regarding a 'gauge' have a look at the code here.

Tip: - When adding Gambas code on this site use the gb button for results similar to the above.
