Twain - Getting available capabilities values with vfp

[oneuser]

Hi there,

I need some help from you with the following functions

ALL TwainGetAvailablexxxxxxxx functions
Like TwainGetAvailableBitDepths
Wants a pointer to an array were they can store the data...

I have looked all day to get this done in Visual Foxpro...
But i have NOT found a way to do this.
I cannot pass a pointer to an array to this function.

Have you any idea how I can solve this ?
I hope that you can help me..


Regards.

Hi,

You can download the gdpicturepro.ocx 3.6 pre-release from here:

https://www.gdpicture.com/ressources/betas/


I've added these new methods:

TwainGetAvailableBrightnessCount()
TwainGetAvailableContrastCount()
TwainGetAvailableBitDepthsCount()
TwainGetAvailablePixelTypesCount()
TwainGetAvailableXResolutionsCount()
TwainGetAvailableYResolutionsCount()

TwainGetAvailableBrightnessNo()
TwainGetAvailableContrastNo()
TwainGetAvailableBitDepthNo()
TwainGetAvailablePixelTypeNo()
TwainGetAvailableXResolutionNo()
TwainGetAvailableYResolutionNo()

you can find the documentation here: https://www.gdpicture.com/references/gdp ... index.html


And here a vfp sample to displays the available pixel types:

Code: Select all

PRIVATE nCpt,;
        oGdPicturePro

oGdPicturePro = CREATEOBJECT("gdpicturepro.cgdpicture")

WITH oGdPicturePro  as gdpicturepro.cgdpicture
     IF .TwainOpenDefaultSource()
        nCpt = .TwainGetAvailablePixelTypesCount
        FOR nCpt = 1 TO .TwainGetAvailablePixelTypesCount
            MESSAGEBOX(.TwainGetAvailablePixelTypeNo(nCpt))
        ENDFOR
        .TwainUnloadSourceManager()
     ENDIF 
ENDWITH
