Image Translucency – Fyne Golang GUI Tutorial 77
This is fyne series tutorial.
in this tutorial, we are going to learn about translucency in fyne , Golang GUI.
To declear image we normally use :
[sourcecode lang=”go” autolinks=”false” classname=”myclass” collapse=”false” firstline=”1″ gutter=”true” highlight=”1-3,6,9″ htmlscript=”false” light=”false” padlinenumbers=”false” smarttabs=”true” tabsize=”4″ toolbar=”false” title=”Source Code main.go”]img := canvas.NewImageFromFile("bg.jpg")
[/sourcecode]
To modify translucency we can use values from 0 to 0.9
[sourcecode lang=”go” autolinks=”false” classname=”myclass” collapse=”false” firstline=”1″ gutter=”true” highlight=”1-3,6,9″ htmlscript=”false” light=”false” padlinenumbers=”false” smarttabs=”true” tabsize=”4″ toolbar=”false” title=”Source Code main.go”]
img.Translucency = 0.9 // you can use 0 to 0.99
[/sourcecode] [sourcecode lang=”go” autolinks=”false” classname=”myclass” collapse=”false” firstline=”1″ gutter=”true” highlight=”1-3,6,9″ htmlscript=”false” light=”false” padlinenumbers=”false” smarttabs=”true” tabsize=”4″ toolbar=”false” title=”Source Code main.go”] package main// import fyne
import (
"fyne.io/fyne/v2"
"fyne.io/fyne/v2/app"
"fyne.io/fyne/v2/canvas"
)
func main() {
// new app
a := app.New()
// new window
w := a.NewWindow("Image Translucency-Alpha")
w.Resize(fyne.NewSize(400, 400))
img := canvas.NewImageFromFile("bg.jpg")
img.Translucency = 0.9 // you can use 0.1 to 0.99
// set content
w.SetContent(img) // we will create image variable
w.ShowAndRun()
}
[/sourcecode]
