_DMxDrawX::DrawToJpg

The contents of the specified area to draw a jpg file. Details are as follows:

parameter	Explanation
BSTR sJpgFilePath	Jpg file name
DOUBLE dLbx	The output range of the lower left corner coordinates X, the document coordinate system
DOUBLE dLby	Output range lower left corner coordinate Y, coordinate system of the document
DOUBLE dRtx	The output range of the upper right corner coordinates X, the document coordinate system
DOUBLE dRty	Output range upper-right corner coordinate Y, coordinate system of the document
iWidth	Pixel bitmap in the width direction, and -1 iHeight not -1, the height and width of the document calculates high, otherwise, it is the system default: 1000
iHeight	Pixel bitmap in the height direction is not -1 -1 iWidth and by calculating the height and width of the document high, otherwise, it is the system default: 1000
