the callback signature, as explained the sample DB, is $1 C_LONGINT: param_scan_type $2 C_TEXT: param_scan_path $3 C_BLOB: param_scan_data $4 C_TEXT: param_scan_context_info
$4 contains parameters such as dataSize dataNumRows dataStartRow bytesPerRow numComponents bitsPerComponent bitsPerPixel fullImageHeight fullImageWidth isBigEndian pixelDataType colorSyncProfilePath procedurally creating a picture from these parameters in not impossible, but it's so much easier to just let the driver create it for you. > 2018/02/02 0:50、Keith Culotta via 4D_Tech <[email protected]> のメール： > maybe another time, if I find where it starts. ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
