Re: ImageCaptureCore - to Variable?

[Keisuke Miyako via 4D_Tech]

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.

yes,

but you receive binary RGB data in chunks,
and you have to build your own JPG, PNG, TIFF, whatever, by code.

do you really want to go down that path?

Is an image available somewhere using this option?

ImageCaptureCore - to Variable?

[Keith Culotta via 4D_Tech]

Hello,

I'm experimenting with 4d-plugin-ica and it's working.  Is it possible to avoid 
scanning to a disk file?
I tried ICA SET SCAN OPTION ($scanner;Scanner transfer mode;String(Scanner 
transfer mode data))
and can see a BLOB is being built.

Using BLOB TO PICTURE  and BLOB TO VARIABLE (with a picture variable) do not 
result in an image.

Is an image available somewhere using this option?

Thanks,

Keith - CDI
