Specifies the bit format of a bitmap.
Declaration
Read-Write Property | Integer |
TBitmapObj | A TBitmap object |
Description
Use the TransparentColor
property to get or set the color that is treated as transparent when drawing a specific bitmap image.
If the TransparentMode
property is “tmAuto”, the TransparentColor
property returns the color of the bitmap’s lower left pixel. Otherwise, if TransparentMode
is “tmFixed”, TransparentColor
returns the explicitly specified color used as transparent in the given bitmap.
Property Value
An integer value that denotes the bitmap’s transparent color.
For a list of predefined color constants and instructions on how to calculate custom color values, see the Working With Colors topic.
Remarks
Setting the TransparentColor
property automatically sets the TransparentMode
property to “tmFixed”. To undo changes made to the TransparentColor
property, set TransparentMode
to “tmAuto”.
