Detailed Description
SafeImage is an image type whose integrity can be verified from the display content with Qt Safe Renderer's output verification.
Note: Qt Safe Renderer is currently in Technical Preview status for Qt Quick Ultralite. A full Qt Safe Renderer support for Qt Quick Ultralite comes in the QSR 2.2 release.
SafeImage supports the same image formats as Image.
To add SafeImage to a QML application:
import QtQuickUltralite.SafeRenderer SafeImage { id: drive objectName: "drive" width: 40 height: 50 x: 70 y: 70 source: "images/drive.png" fillColor: "#000000" }
See also Qt Quick Ultralite application with safety-critical items.
Property Documentation
fillColor : color |
This property holds the background fill color of the item. It affects the non-opaque images only, and its default value is transparent.
Note: If you are using the output verification feature, do not use the default value "transparent". Instead, define an opaque background color.
height : real |
This property holds the image height. The default value is 64.
opacity : real |
This property holds the opacity of the item. Opacity is specified as a number between 0.0 (fully transparent) and 1.0 (fully opaque). The default value is 1.0.
source : string |
This property holds the resource locator of the image. The image format and URL scheme can be any format or scheme supported by Qt.
SafeImage accepts an absolute resource URI, for example "images/drive.png".
Note: Resource URI must be lower-case.
width : real |
This property holds the image width. The default value is 64.
x : real |
This property holds the x-coordinate position of the image.
y : real |
This property holds the y-coordinate position of the image.
