Create A Multi-Page Tiff File?

Jan 29, 2010

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]...

Stream (and Convert?) Multi-page TIFF?

Aug 10, 2009

I 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)

Multi-Page TIFF Document (Array Of Bytes From Stream)

Mar 17, 2009

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.

VS 2010 : Write A Program Which Loads A Tiff Image On Picturebox?

Mar 6, 2011

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).

Public Class Form1
Dim StartX, StartY, EndX, EndY As Int16
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Writing A Single-page Tiff File

Oct 27, 2011

We 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.

Concentration Game VB With PictureBox Showing Pictures

Mar 15, 2012

The project: As one of the projects for my Advanced Visual Basic course, I'm implementing a Concentration game very much like this project:(url)

The issue: I've got most of the logic working but I'm getting really weird behavior when I flip the cards. The first one flips fine. The second one is *supposed* to flip and hold for a second (I use a Thread.Threading.sleep(1000)) then flip back to covered if they're not a match.

For some reason, if they don't match it never flips the second card over so that you can see the picture underneath. It evaluates correctly but if the pics don't match, you never get to see the 2nd card.

Secondary issue (not as critical): At lines 67-79 there are some bits of code that are commented out. I'm trying to use a For Each loop to go through all my picture box controls and assign them to the array of structures and then assign the cover image without having to do it one at a time. It would save me about 250 lines of code and help me to still respect myself in the morning.

In addition to including my code, I will upload a copy of the entire project folder in case anyone wants to compile it and see the behavior for themselves.[code...]

PDF Viewer Showing Last Page

Feb 26, 2010

I have a asp.net app that writes a pdf to file. Then, later that file is opened into a window (standard acrobat reader) for viewing. The entire document loads as it should, but the Reader initially shows the last page in the document on the screen. The user must then scroll up to the first page. It doesn't happen all the time (about 50%) and occurs across several test computers. Is there a switch in the code I'm suppose to use in creating the file or displaying the file to tell the reader to "start displaying the document on the first page?"

Getting Multi-page Output To Printer?

Aug 3, 2010

I am continuing a previous thread to keep it from becoming tooooooo long. I tried most of the helpful suggestions offered by kind forum contributors but can't seem to make them work. I tried to analyze somewhat but it's beyond my skill level. So a different approach was to try to incorporate the code in the PrintDocument1_PrintPage event of my application that prints acceptably, but only prints first page of multi page document. I had three somewhat different approaches offered by John Anthony Oliver, ACAMAR, and Crazy Pennie. I cut the code and placed in the PrintDocument1_PrintPage event code. All three approaches made the "Printing"message box page counter go wild without outputing to my printer. Family Man Mike suggested resetting the variables after the e.HasMorePages=false line. I tried that approach but couldn't make that work for me, I really don't comprehend but made an attempt such as num_of_pages = 0, startVal = 0, endVal = 0. That had no affect on the functionality.

C# - Separating Multi-Page Tiffs Into Separate Pages?

Jan 20, 2012

Currently I am using .NET to break apart multi-page tiffs into separate jpeg/pngs. The process on its own is perfectly fine. But after few weeks, I notice one big flaw in the page sizes. Each page I separate is the same (width/height NOT FILE SIZE) as the whole TIFF document combined. When the TIFF is displayed,this creates a massive black spot on the right/bottom of the image. This is a very big flaw as I can't determine the physical dimensions of each page as I am separating them. If I know ahead of time, I can at least write up some kind of cropping mechanism.

Crystal Report In Application Showing Blank Page?

Jul 14, 2009

I have a crystal report that works in Crystal Reports Writer XI just fine. I run the report in the application passing the same information that I use to test in the CR Writer and the report is completely blank. No exceptions what so ever are raised in the application.I've opened the report in VS2008 and resaved it and verified the database and still nothing. I have two different versions of the report. The report is using stored Procs and I have verified that it is loading the report because it is accepting the parameters I setup in the report. If I change the name of the parameter I'm saving to something invalid it then throws an error.
