Declaration

Delphi

function LCDImageExR(ImageKind, x, y: Word; Image: HBITMAP): Integer;
procedure LCDImageEx(ImageKind, x, y: Word; Image: HBITMAP);

C/C++

SOPAD_API int SOPAD_LCDImageExR(int ImageKind, int x, int y, HBITMAP hImage);
SOPAD_API void SOPAD_LCDImageEx(int ImageKind, int x, int y, HBITMAP hImage);

ActiveX

HRESULT LCDImageExR([in] long ImageKind, [in] long x, [in] long y, [in] OLE_HANDLE Image, [out, retval] long* Result);
HRESULT LCDImageEx([in] long ImageKind, [in] long x, [in] long y, [in] OLE_HANDLE Image);

Description

Function displays image on LCD or stores image for further processing.

The only difference between LCDImageEx and LCDImageExR is that LCDImageExR function returns value.

NOTE: This function only works with signature pads with colour display. For B/W Pads please see SetSignImage or SetSignImageEx

Arguments

ImageKind

Type of image

Value	Description	Return value	extentions
1	Branding: after sign logo (+Pad V2 and similar)	0
2	View document on LCD	0: success 1: error 2: image too large	x and y is the position of image.
3	View document on LCD, display sign button		x and y is the position of image.
4	Store sign page		x and y is the position of image.
5	Clear sign page, store foreground image
6	reserved for i don't know
7	continuous scrolling mode		the parameters represents x : ActualPageNumber y : MaxTileNumber
8	page requested		the parameter represents x : actual page number, starting with 1 for the first page in PDF, requested by OnDeviceButton(Ex) with message type HID_CMD_BUTTON_JUMP_PAGE y : page count in PDF

x and y

Position of image.

Image

Bitmap handle.

Return value

Return value depends on ImageKind, see above

Sample

C# - StandardSignMode

C# - SignInDoc Mode

Bitmap bmp = new Bitmap(640, 470, System.Drawing.Imaging.PixelFormat.Format24bppRgb);
                    
//  Set as SignInDoc Background
SigDev.LCDImageExR(4, 0, 0, (int)bmp.GetHbitmap());
//  Define a Signature Rectangle (for example with Size of 380x190 and place the signing area in the bottom center)
SigDev.CreateSignatureRectangle(130, 280, 380, 190, 0);
// Start signing
Capturing = SigDev.startCapture("", true, true, true, true, ref padsetting);
