Hi
I'm having a problem with images I cannot figure out, hope you can help me
out…
What I'm trying to do is download and place a png scaling down if necessary
to fit the screen width.
My assumption: If the height of the image is larger than the height of the
device, then the image is not rendered on devices but it is on simulator
with no problem.
The problematic image is 1536x4272 and 1MB.
BUT the same image scaled to 768x2136 and 714KB works fine both on
simulator and devices, so my assumption might not be right and I'm totally
lost. Or maybe it's a problem with the image, but then why is it working on
simulator?
To scale the image I'm setting the background of a Label. As I said The
code below works on simulator but not on iOS or Android.
public void start() {
if(current != null){
current.show();
return;
}
Form f = new Form(new BoxLayout(BoxLayout.Y_AXIS));
f.setScrollableY(true);
Container loading = new Container(new
BorderLayout(BorderLayout.CENTER_BEHAVIOR_CENTER_ABSOLUTE)).add(BorderLayout.CENTER,
new InfiniteProgress());
Util.downloadImageToFileSystem("https://dl.dropboxusercontent.com/u/47281022/IMGP0.png";,
FileSystemStorage.getInstance().getAppHomePath() +
FileSystemStorage.getInstance().getFileSystemSeparator() + "IMGP0",
new CallbackAdapter(){
@Override
public void onSucess(Object value) {
Image img = (Image) value;
int imgHeightDevice =
(Display.getInstance().getDisplayWidth() * img.getHeight()) /
img.getWidth();
Label l = new Label() {
@Override
protected Dimension calcPreferredSize() {
return new
Dimension(Display.getInstance().getDisplayWidth(), imgHeightDevice);
}
};
l.getAllStyles().setBackgroundType(Style.BACKGROUND_IMAGE_SCALED_FIT);
l.getAllStyles().setBgImage(img);
f.replace(loading, l, null);
f.repaint();
}
});
f.addComponent(loading);
f.show();
}
