IsFloat Property (original) (raw)
Summary
Determines whether the image data is float.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public bool IsFloat { get; } @property (nonatomic, assign, readonly) BOOL IsFloat; public:
property bool IsFloat {
bool get();
}
Property Value
true if the image data contains signed (negative) values; false, otherwise. The default value is false.
Floating point values are usually converted during load to integer values. You can avoid this conversion by setting CodecsLoadOptions.NoImageDataConversion = true to load the original floating point values. See Working With Floating Point Images for more details.
The floating point values can be positive or negative even when CodecsImageInfo.IsSigned is set to false.
Example
using Leadtools;
using Leadtools.Codecs;
public void CodecsImageInfoIsFloatExample()
{
string srcFile = Path.Combine(LEAD_VARS.ImagesDir, "cannon_noisy.png");
using (RasterCodecs codecs = new RasterCodecs())
using (CodecsImageInfo info = codecs.GetInformation(srcFile, true))
{
if (info.IsFloat)
{
Debug.WriteLine("The source file has floating point image data");
codecs.Options.Load.NoImageDataConversion = true;
using (RasterImage image = codecs.Load(srcFile, 1))
{
/* do something with the floating point image data */
}
}
else
Debug.WriteLine("The source file does not have floating point image data");
}
}
