Property Documentation
alignment : enumeration |
A bitwise or of one horizontal and one vertical flag from the following:
| Constant | Description |
|---|---|
Qt.AlignLeft | Left align |
Qt.AlignHCenter | Center align (horizontally) |
Qt.AlignRight | Right align |
Qt.AlignTop | Top align |
Qt.AlignVCenter | Center align (vertically) |
Qt.AlignBottom | Bottom align |
See also Qt::AlignmentFlag.
autoMax : bool |
Whether the maximum value for the colormap should be determined from source.
See also ImageView::max.
autoMin : bool |
Whether the minimum value for the colormap should be determined from source.
See also ImageView::min.
colormap : var |
The colormap to use when source is a list of values. This property can either take a Gradient, or a color map enumeration value from ColorMaps.
The values of source are mapped to a color using min and max (i.e. if the value is less than or equal to min, it will be assigned the value at 0; if the value is greater than or equal to max, it will be assigned the value at 1). To invert a colormap, swap the values of min and max.
See also ColorMaps::colors.
fillMode : enumeration |
One of the following:
| Constant | Description |
|---|---|
Qt.IgnoreAspectRatio | Stretch the image to fill |
Qt.KeepAspectRatio | Preserve the aspect ratio |
Qt.KeepAspectRatioByExpanding | Preserve the aspect ratio by cropping |
See also Qt::AspectRatioMode.
max : real |
min : real |
mirrorHorizontally : bool |
Mirror the image horizontally.
mirrorVertically : bool |
Mirror the image vertically.
paintedRect : rect |
smooth : bool |
Sets whether the displayed image should be pixelated or smooth (linearly interpolated).
source : var |
The data source for the displayed image. This can be a QImage, or a 1D/2D list of reals.
If a list is provided, it will be converted to a color image using the colormap. A 1D list will be converted to a 2D list using sourceSize. The 2D data will be interpreted using "image" indexing (i.e. the first axis is Y and the second axis is X). If your data uses the opposite indexing scheme, use the transpose property to correct it.
sourceSize : size |
The size of source. When source is a 1D list, this property can be set to the size the list should be interpreted as.
transpose : bool |
Transpose the image.
