Hello ,a question puzzles me so much time ,who can help me?
The most important problem in my design is that i can not get the actual width
and height of image after changing the source of image.
// the example : the actual size of "0001.jpg" is 5120*3840, "0002.jpg" is
3000*4000,
// my screen is 1920*1080 , so the image should be scaled,
//**********************************************************
Image {
id : image1
source:"0001.jpg"
sourceSize.width:1920
sourceSize.height:1080
Component.onCompleted:{
/*
* this the process of scaling width and height .
* image size:5210*3840 after scale :1440*1080
image size:7680*4320 after scale :1920*1080
image size:3000*4000 after scale : 810*1080
*/
width = 1440
height =1080
}
}
keys.onPressed:{
if (event.key == Qt.Key_Right) {
image1.source = "0002.jpg"
console.log("image1.width::"+image1.width+"
image1.height::"+image1.height)
//********************************************************************
// here, the actual size of "0002.jpg" is 3000*4000,but after pressing the
button of "Right",
// the image1.width couldn't change, it is 1440,height is 1080
// so this is the problem: after changing the source of image, the width and
height of image1(id) could //not change at the same time
}
}
