Viewing a multi-page .tif

[richardc]

I need to display multi-page .tif files I am using DCHTMLVIEWER but it only displays the first page. Does anyone know of a way to accomplish this using eXpress and/or xBase++.

Thanks,
Richard

When I try to open the .TIF in Windows Edge Explorer, it reroutes it to the Windows Photo Viewer.

You may have to do it this way:

DC_SpawnUrl( 'c:\bhs\myfile.tif')

Thanks Roger.

I am trying to allow users to view the multi-page .TIF files within the DCHTMLVIEWER and not have to spawn a new window. Maybe a .TIF to a .PDF conversion, then to the DCHTMLVIEWER?

Hi,

TIF isn't supported by most browsers, so it will be a problem with htmlviewer.

Converting to JPG, PNG or as you mentioned to PDF since it is a multi page will be the way to go.

hi,

have a look at "Freeimage"
there is a Xbase++ Wrapper using Ot4XB see this Attachmen
viewtopic.php?f=2&t=2862&p=17108

Purpose of FreeImage
A clear picture about a project is important, because it is that picture that defines which
features are implemented and which are not.
FreeImage supports:
 Loading and saving of as many bitmap types as possible
 Easy access to bitmap components, such as palettes and data bits
 Converting bitmap’s bit depths from one to another

 Accessing pages in a bitmap when there are multiple, such as in TIFF

 Basic manipulation of bitmaps, such as rotation, flipping and resampling or point
operations such as brightness and contrast adjustment
 Alpha compositing and alpha blending

Thanks Jimmy. I will check Freeimage out.

I found a command line free product that converts from multi-page tiffs to a pdf. It is called nconvert. I am running it via Runshell() from within my application, doing a pdf conversion and then sending it to DCHTMLVIEWER. It is fast and works perfect.

Thanks for everyone's help.

It is not free when you use it commercially!
