Accessing rendered SVG

David Chamberlain20-Sep-02 2:56

20-Sep-02 2:56

I've got a desktop application in development in VC++ 6 that processes data and creates an SVG file that can be seen in a local html file that was built to show the SVG file and some supporting info. No network connection needed, no server, just local desktop.

What I would like to be able to do is to use the Adobe SVG viewer as an ActiveX control to read the SVG file and do the rendering, but instead of displaying the SVG in the application, I need to be able to access the rendered bitmap and operate on the individual pixels. Even converting the SVG into a JPG would allow me to use the CxImage or FreeImage library to read the JPG file and have access to the individual pixels.

A search on Google provides many hits on converting SVG into JPG, but they're all Java, and that won't cut it. I need some C++ code.

Has anyone done something like this that would be able/willing to share some code to get me started, or point me in the right direction? I need to be able to load, create, and manipulate the SVG ActiveX control in a non-visible manner, and I need access to the rendered bitmap.

Thanks,
Dave

You might get something usable from libSVG.

Property Sheet

I have started a MDI project with CFormView as the base class.

I have inserted a property sheet using the Menu item: Project¦Add to Project¦Components and Controls ->property sheet. But I cannot view the property pages nor the frame. I give access to CMyProjView class to have the property sheet embedded into the CFormView.

Any ideas how to activate this property sheet?

If you need the FormView only for containing the property page, you could also use this [^]

This does what I need it to do, but the code seems awfully longwinded for what it does. i.e. only 2 property pages.

Well, it has to simulate the property sheet with a tabbed control and a number of dialogs 'by hand'. The code itself is good and stable.
If you only need the PropertyView once, you maybe are better off embedding a sheet in the CFormView and handling OnSize().
Construct the CPropertyPages in your CPropertySheet-derived class, AddPage() them in OnIntitialUpdate() and the MUST be there.

Heya

I'm not too sure about your method (i've never done it that way), when i embed controls in views i do it this way ->

Create the property sheet as per normal and add it into your FormView as a member variable.

Overide the OnSize method for your formview and call
m_myspropsheet.MoveWindow(cx,cy) etc....

Moving Child Window

I have mainwindow.Inside that mainwindow there are various child windows which is having WS_CHILD style as like sqldiagram.When i move one child window sliding over the other as in sql Relationship Diagram,the window which i move should have the highest z-order i.e..the window which i move should be visible when i move over another child window ,but for me it is going behind the child window.

Sorry if iam not explaining properly.

If u still cant understand my quesiton,just open the Sql Server and see the relation ship diagram and move the tables.

If I understand what you want to do, you want a currently dragged child-window to get the "closest-to-viewer" Z-order?

SetWindowPos and HWND_TOP is probably what you're looking for.

Run Console app and handle input and output

Hello,

I have a console app that I can launch using CreateProcess() however I need to obtain the input and output stream from this app so I can do some processing on the data it provides (basically, automate the process of typing data in and reading the output from the console application).

I guess there are some useful articles out there in CP? Can someone point me in the right direction please??

Much appreciated.

Adam.

CSliderCtrl and TB_THUMBTRACK

I don't know whether my VC is messing up or if my MSDN is missing some entries.

I'm trying to handle the TB_THUMBTRACK message for my slider control, ClassWizard has no entry for it and although MSDN mentions it it doesn't specify the format of the handling function??

How do i handle this Message?

is there any reason you want to do a thumb-track on the slider? you get the same results by just using OnHScroll:

void CSettings::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar) 
{
   CSliderCtrl *theThing=(CSliderCtrl*)pScrollBar;

   if (theThing==(CSliderCtrl *)GetDlgItem(IDC_CONTROL_I_WANT_TO_WATCH)) 
   {
     pos = theThing->GetPos();
   }
}

this will be called every time the thumb moves (just like a THUMBTRACK event on a scrollbar)

-c

As always, it's bread and circuses. And while bread is down right now, circuses are way up.

different HWND, but same HDC

I've got 4 views that are child windows of one view.
Parent view calls children's specific method to do some drawing.
And in this method different child views have different HWND, but _SAME_ HDC
so drawing occurs only in 1 child view.

any suggestions?

thanks in advance.

Opening only one instace of template in MDI

Hi,

I want to open only one set/window (doc + ChildFrame + view) on pressing menu button which replaces OnFileNew().
If the button is pressed again the window shoud be brought forward if it was unactive.
I found CDocTemplate::GetNextDoc() function which stores documents (CDocument*) created for any particular template. If GetFirstDocPosition() gives NULL no document was instantiated therefore no window displayed, so the button should create/displayed this window. Otherwise activate the already existing one. Is my understanding correct or maybe there are more elegant solutions?

so you want only one document to be open in an MDI application?
if a document is open you want it to be "activated", otherwise create a new one?
