Re: Scale Large Pages, but not small pages when printing

I found another way around my issue. Rather than trying to print the original long image I am now splitting that image into pages before printing. This way I don't have to resize or play with resolution so I'm not losing any quality from my original image. In case anyone is interested I'll post my c...

Re: Scale Large Pages, but not small pages when printing

I've worked out a way to do this, but it has a problem. My process is simply to check to see if the image is more than 8.5" wide and if so resize it to 8.5" wide then set the horizontal and vertical resolution back to what they originally were. This resized my test image that was originally 26.375" ...

Scale Large Pages, but not small pages when printing

Hello, I am trying to give my users an option that will shrink large pages but leave small pages alone. We have many types of documents that we scan or capture from web pages. The documents are saved as multi-page Tiff files. The user has an option to select several documents to be printed, exported...

Re: Option has not been unlocked

Thanks for the quick response. Unfortunately I could not determine which method was causing the message, but moving the license info to the top of the form_load method resolved the issue.

So problem solved. Thanks again,

Neal.

Option has not been unlocked

Hi Loic, Something strange is happening today. I've been working on an app for a few weeks using GDViewer and GdPictureImaging. I've had no problems up until now. When running the application I now receive the following messages: Image processing: This option has not been unlocked ! Please, unlock i...

Grey background on scanned documents

Hello Loic, I'm having a problem with documents I scan having a grey background instead of white. When I scan the same document with the same scanner using other software the background is white. In both cases I am scanning greyscale. My version is 6.4001 (I'll update to the latest). The code I'm us...

HTML to Image

Is there any function to convert HTML to an image. I don't want to convert a web page as can be done with the CreateGdPictureImageFromHTTP method. I want to supply the HTML as a string and create an image as that HTML would appear in a web browser. That being said, the HTML I intend to convert is ve...

Re: Can I run GDPicture as a Windows Service?

Just a quick note. I use GdPicture in a Windows Service without any issues. I am not however attempting to control a scanner. The App I created to run as a service simply watches a folder and coverts any TIFF files it finds into PDF becuase the particular client's multi-function-device will only sav...

Re: Slow Printing

I modified my code to use MutiPage Tiff instead of PDF and it prints MUCH faster. I'm ok with this format, but I would still like to know why the PDF files have the stated problem. There will undoubtedly be times when I need to print PDFs

Re: Add image to pdf

I decided to keep adding my corrections to this post so that if anyone else ran into similar issues this would be here to help. My previous post worked great for a single image, but for multiple images, only the first was included properly. It turns out I was still having the same trouble as noted a...

Re: Add image to pdf

Working now. Just goes to show you that RTFM (Read the fine manual) is always the best first step. I had missed the following line in the documentation: All the used images must be added into the pdf before using the PdfNewPage() function, otherwise this function will return 0. ! Moving the PdfAddIm...

Add image to pdf

Hello Loic, I'm trying what should be a fairly simple task. To create a pdf with a series of images in it from my database. I retrieve the images without any trouble, and can display them in a GdViewer control with no problem. SaveToPDF also works fine. But creating a PDF and adding the image, so th...

As a addition to this feature, being able to view DICOM images with the viewer control would also be very helpful.

Dicom Image Support

Here's a feature i would find useful. The ability to save as a DICOM image. In case you are not aware DICOM is the standard format used in Medical Imaging. Here's a link to information on DICOM: http://medical.nema.org/

Thanks,

Neal.
