Examples

Prior to compilation, load matdata_utils.c to the workspace by executing the following LabTalk command:

Run.LoadOC("Originlab\matdata_utils.c", 16);

To retain matdata_utils.c in the workspace for successive sessions, drag and drop the file from the Temporary folder to the System folder.

EX1

#include <..\originlab\matdata_utils.h>
//this example assumes that there is already an image in the active matrixsheet in MBook1 matrixbook
void adjust_image_brightness_ex1()
{
    MatrixObject        mobj;
    if (!mobj.Attach("MBook1"))
    {
        out_str("Attachment failed!");
    }
    int adjust = 20;
    adjust_image_brightness(mobj, adjust);
}

EX2

#include <..\originlab\matdata_utils.h>
#include <image_utils.h>
//this example assumes that there is already an image in the active matrixsheet in MBook1 matrixbook
void adjust_image_brightness_ex2()
{
    MatrixObject        mobj;
    if (!mobj.Attach("MBook1"))
    {
        out_str("Attachment failed!");
    }
    Image img(mobj);
    if(!img.IsValid())
        return;
    BITMAPHANDLE* pLBmp = img.GetLBmp();
    int adjust = 20;
    adjust_image_brightness(pLBmp, adjust);
}
