 Does the Annotation Toolkit have the capability to create a highlight annotation programmatically?
Our C/C++ toolkit provides an interface to the low-level annotation library in visant32.dll. VisImage for PowerBuilder uses the visant32.dll, but does not yet expose the low-level interface. At presen...
- How do I handle a multi-page TIFF with annotations? The annotation is appended as another page but does not necessarily correspond to the page of the TIFF it was done upon.
The majority of our customer base requires separation of annotation and images, thus the reason for its current design. Therefore, if your TIFF file has pages 1 and 3 with annotations, then the corres...
- Is it possible to specify that multiple page documents be scanned in as multiple image documents (ie, TIFF) format?
Yes. Use the function fu_set_multipage to specify if TIFF files should be written as single image files or multipage files. See the help file for more information.
- Is it possible to access a specific image in a TIFF file so that it may be used elsewhere?
When loading an image, specifiy a subindex value (zero based) to indicate which image page you want to load. See the help file for more information.
- Any attempt to print causes error "Error writing to image file" for file type BMP32? What's the problem?
This is because you've selected a 32bpp image format to export to and the ImPrint Bitmap Driver is setup for only 1bpp. To support color printing, you will need to set the ImPrint Bitmap Driver to...
- Is it possible to append a new scanned page to an existing multi-page scan file (TIFF) using VisImage for PowerBuider?
Yes, but make sure that you call fu_set_multipage_export with a value of 1, so that the image will be appended at the end of the file. Then call fu_save_image passing in the T...
- We need to remove blank pages that are scanned when the scanner is in duplex mode. Also, all the files we scan are multi-page. How do I do this using the functions in VisImage for PowerBuilder?
We have a morphological API in our C/C++ toolkit that is not published in our Power Builder toolkit. Since VisImage for Power Builder uses the DLL, you can create an External API call to the function ...
- When scanning directly into the VisImage for PowerBuilder control, how do I determine the file type for when I export it to a file to get a blob to save into the database?
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...
- When saving an image to a temporary JPEG file, the error: -5 (Image BitsPerPixel unsupported in function) is returned. What's the problem?
You are receiving this error because you are trying to store a 1bpp TIFF image as JPEG, and JPEG standards only support 8 and 24 bpp. To get around this error, and still store in the database as...
- 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?
There is a page variable that can be used in the load function as well as functions fu_prior_page and fu_next_page. Please review the help file documentation for more information....
- Each time a JPEG is retrieved, displayed, updated, saved to file, loaded into blob and saved back to the database the quality of the image deteriorates more. How can I preserve the quality?
The fu_set_comp_quality function will set the compression/quality factor used in export of images that support a lossy compression. Currently JPEG, BXS and PNG are the only formats that use this ...
