Manual - Barcode
Introduction
This class is an abstract class which contains the base methods to create barcodes. It is used by 1D and 2D barcodes.

Method explanations
-
Parse(string
text ) — Analyzes atext message to draw afterwardsDescriptionThe data you pass to thetext argument must be supported by the type of barcode you use.
Check each barcode's introduction section to obtain more information on how to use this method within each symbology. -
Draw(Graphics
image ) — Draws the barcode on theimage DescriptionThe value of theimage argument must be an image resource. The size of the image can be defined by the value received fromGetDimension() . -
GetDimension(int
width , intheight ) — Returns an array containing the required size for the imageDescriptionReturns an array in which the first index is the image width and the second index is the image height.
The arguments are used to specify the starting point of the drawing. Should be 0 for both.
TheBCGDrawing class uses this method to create the image resource.Returnsarray(int, int) - [0] is the width, [1] is the height -
GetScale()
—
Gets the scale of the barcode
DescriptionGets the scale of the barcode. The value is the number of the "smallest" unit in pixel.Returns
int - value in pixels -
SetScale(int
scale ) — Sets the scale of the barcodeDescriptionThe barcode will bex times bigger. Then a pixel will bex byx for its size. -
GetForegroundColor()
—
Gets the color of the bars
DescriptionGets the color of the bars of the barcode.Returns
-
SetForegroundColor(BCGColor
color ) — Sets the color of the bars -
GetBackgroundColor()
—
Gets the color of the spaces
DescriptionGets the color of the spaces of the barcode.Returns
-
SetBackgroundColor(BCGColor
color ) — Sets the color of the spaces -
SetColor(BCGColor
foregroundColor , BCGColorbackgroundColor ) — Sets the color of the bars and spacesDescriptionAn easy and fast method to set the color of the bars and spaces. Check theSetForegroundColor() andSetBackgroundColor() . -
GetOffsetX()
—
Gets the X offset
DescriptionGets the X offset of the barcode in pixels. The value isn't multiplied by the scale.Returns
int - value in pixels -
SetOffsetX(int
value ) — Sets the X offsetDescriptionSpecifies the X offset of the barcode in pixels multiplied by the scale. The required size returned byGetDimension() will be modified accordingly. -
GetOffsetY()
—
Gets the Y offset
DescriptionGets the Y offset of the barcode in pixels. The value isn't multiplied by the scale.Returns
int - value in pixels -
SetOffsetY(int
value ) — Sets the Y offsetDescriptionSpecifies the Y offset of the barcode in pixels multiplied by the scale. The required size returned byGetDimension() will be modified accordingly. -
AddLabel(BCGLabel
label ) — Adds a label to the graphicDescriptionAdds aBCGLabel object to the drawing. -
RemoveLabel(BCGLabel
label ) — Removes a label from the graphicDescriptionRemoves a specificBCGLabel object from the drawing. -
ClearLabels()
—
Removes the labels from the graphic
DescriptionClears the
BCGLabel objects from the drawing.
