TImageEnView.IsEmpty

TImageEnView.IsEmpty


Declaration

function IsEmpty(QuickCheck: Boolean = True): boolean;


Description

Returns True if the size of the image is less than 2 x 2 pixels.
If QuickCheck=False, IsEmpty returns true if an image has not been assigned or loaded

Note:
IsEmpty only checks the active bitmap. It does not consider multiple layers.
Also see IsBlank which returns true if the image is only one color


Example

// Does TImageEnView have any content
haveContent := ImageEnView1.IsEmpty( False ) and (ImageEnView1.LayersCount <= 1);


Compatibility Information

ImageEn v10.0.1 and older had an IsEmpty2 property, which is the same as IsEmpty(False).
I.e. change code that is "ImageEnView1.IsEmpty2" to "ImageEnView1.IsEmpty(False)"
