When we acquire an image from a Twain device, we receive it as raw data. The Twain driver tells us the properties of the raw data, and we build an image internally. The function you&nbs...
- Is there any way to get VisImage for PowerBuilder to provide a blob without first saving it to a file?
The only way to populate a BLOB data type is from a file. This is a PowerBuilder PowerScript limitation. PowerScript provides no means of reading/writing memory streams, only file streams. As a result...
- Can VisImage for PowerBuilder load and then page through a multi-page file or must each page be loaded separately when it is to be viewed?
