Ok what's happening is I'm pulling in a Tiff file that can have multiple pages. I selected the first frame, draw a stamp image to it and save it as a different file name.When I do this, it is only saving the first page of the tiff file. How do I get all of the pages to save?
vb
NetDMS.exportDocumentImageWithAnnotations(_workflow, disn, "C:JCEmailFld", "emailDocument" + currEmailDoc.ToString)

I have a bunch of images that I want to save as 1 tiff file.
I can get it to read just fine. But It is not picking up frames. I think it has to do with the encoderParamters.[code]...

View 9 RepliesI have built a simple image viewer in .NET and have the requirement to display multi-frame TIFF images in the browser. Presently, I have a (ashx) handler setup to stream back JPEGs that are co-mingled in the same database as the multi-frame TIFF's and it's worth mentioning that this handler will also return the first frame of the TIFF file in its current state. In the VB.NET code below (part of the handler) I am able to identify if a TIFF file has multiple frames and I started attempting to stitch the frames together but have not had any success yet. Has anyone returned multi-frame TIFF's using a similar approach? Note: I used the How to open a multi-frame TIFF image as a reference when developing the code below.
context.Response.Cache.SetCacheability(HttpCacheability.NoCache)
context.Response.Cache.SetNoStore()
context.Response.Cache.SetExpires(DateTime.MinValue)

When looking at an array of bytes from a stream for a multi-page tiff document, can you determine where one page stops and another begins? I want to take a multi page document, let's say 50 pages and allow a user to pick different pages of that to make other muti-page documents.

View 11 RepliesWe are using vb.net to write tiff images. After the image is first scanned into the system, we read it into bitmap memory, then we write it back out as a tif and pass in arguments that tell it what to put in the header. When we look at the original file, the header shows the "Subfile type" as "single page of multi-page image". But we noticed that after the file is written, the header now shows the "subfile type" as "Full-resolution image". We do not currently pass any argument in that tells it to do that.Is there a way to pass an argument into the function that writes the tiff file to tell it we want a single-page tiff and NOT a full resolution image? For some reason, our customer's tiff reader is not accurately reading some of these files and we believe it might be the cause of this.

I have converted pdf file to Tiff file using 3-party software. When I open the new Tiff file using 'Windows Photo Gallery', I can view both pages of the converted file. However, when I open the the Tiff file in a picture box in my app. I can only view the first page. So, my question is how can I view multiple pages of a Tiff file in a picture box?

View 1 RepliesI am trying to draw some multi colour text onto a form using the paint event and the GDI+ object (note it has to be done using the GDI as i will be needing to scale and do bmp pixel manipulation on the resulting graphic . I have so far managed to create a class and collection winch allow the user to move the text around and change the displayed string, font and colour.
My question is how can i change my class so that it draws multi colour text? and if possible allow the user (uinsg the mouse to graphically select parts of the text.
Below is a work link to the project so far:-

I am drawing five images in a row. The five are the same thing at five different zoom levels. Therefore, only one of the five will be displayed at any one time, but the others have to be there because there can be over 100 images being displayed on the screen at any one time, and each drawing is quite complicated. If I were to draw them all on the fly, then zooming would require that all 115 images be recreated and redrawn with each zoom. That's painful. To avoid that, I draw all five zoom levels of each image. When the user iteracts with the form, they will be interacting with, at most, two of the images, so when they interact with the form, only two of the 115 have to be redrawn, though those two have to have all five zoom levels drawn, for a total of 10 images.

I am trying to write a program which loads a tiff image on picturebox. Then the user clicks somewhere on loaded image to set the starting x,y coordinates and clicks again to set the ending x,y point. Then clicks the run button and the starting and ending x,y points are written on label.
Just to test the program a loaded a tiff image that has a dimension of 75x75 pixels. When I click upperleft and downright corners of the image, the program outputs the coordinates as starting x,y as (103,89) and ending points as (170,157). The program outputs wrong coordinates becayse the image has 75 rows and 75 colums only. To me, it should have outputted starting point as (0,0) and ending points as (75,75).
