I'm dealing with what I think is a multipage EMF file. Does your viewer handle this type of files?
If so would it be possible for you to send me the compiled version?
thanks
Loris

I am not sure. It depends on whether IPicture supports multipage EMF files. The EXE is already included in the ZIP file. You can give it a try.

Thanks, I've tried.
The bad news is it only views the first page ... no sign of the rest.
The good news is that I found this other piece of software that does the job perfectly:
http://www.lvbprint.de/html/splviewer1.html
thanks for you time,
Loris
PS why do you write "Download source" when there also is the compiled exe version? Wouldn't "Download source and binary" be better?

search your system for the library location, then make sure the linker has a path to the library location identified in the "library default locations" studio options

I can load bitmap image in Dialog or Sdi document. But if another window overlap my imageviewer, image is disappeared.
How can i solve the problem.

You need to put your drawing code in OnPaint().

I am printing images (using Visual C++, MFC application) but they're too small, or too clear. What is going on?
|
|
|
|
|
|
|
Check out the printing code in this sample (CImgViewerView::OnPrepareDC() in ImgViewerView.cpp).

Any idea, how can I ROTATE 90, 180 etc using an IPicture object, once it is loaded and showing on screen...
Thanks

How to get image's data (pixels value) directly from the IPicture object.
Thanks.

I wrote a code look like this to use in my little work. Its duty is
1. Load BMP image as resource by LoadBitmap function (4 images)
2. Shows one image on screen
3. Make some change by using the images
4. Show result
Every thing works well(But it is very slow when run). However after I changed the code by adding WriteDIB() (I want to save the result image into file) and compiled it, it can perform on its duty except for sainge the file(there is notthing happen). The program still run without any error.

what would be the coding to load the bmp in a static control of a Dialog tather than in a Document ?
Thanks in advance

You can use LoadImage() to load the bitmap and call CStatic::SetBitmap() to set the bitmap.

I was testing this program and noticed that if I open 3 or more image files the program crashes or gives me an error message.
To recreate the problem I clicked on the toolbar button "Open" , then I get my dialog box which gives me the option to open a file. If I do this more than 3 times with the same files I will get an error message saying "cannot open file it is not supported ..."
I have tried it on dfferent computers on a DELL Dimension V333 and on a Compaq Pressario and I get the same problem.

I cannot reproduce the problem. What OS are you using? Does it happen with any image files or only a specific image file?
|
|
|
|
|
|
|
I recompiled the code and run the program again and could not reproduce the problem. It must have been something wrong with my compiler. By the way I'm using visual c++ 6.0.
Sorry, false alarm

Can someone suggest how 2 Save the Image Loaded in a format which can be reloaded whenever required.
I do not wish to copy the original file ,if i have all the image data in my program.

Let's see.....
1. The question has little to nothing to do with this article.
2. You're not committed enough to this community to get an account or even to indicate that you're going to check back for a reply.
3. You didn't ask in the proper forums.
4. You didn't say please.
On what level do you think this is the way to solve your problem ?
