Blitting two different graphic bit depths? Alan Chambers30-May-02 1:59 Alan Chambers 30-May-02 1:59  Hi all, just wanted to know if there is some way of blitting a 16-bit RSB graphic (manually loaded into memory using its unique binary template) to a 24-bit graphic surface? I realise that it could be done by normalising the 16-bit information of 2-bytes per pixel to three bytes per pixel and then blitting but there are two issues with this: a.) I didn't want this extra step unless it was UNAVOIDABLE. b.) I'm not sure where to start with the conversion process? I'm using DirectDraw to blit to the screen, and some custom surfaces to store the graphic data (Basically I'm trying to blit from a 640x480 16-bit plain surface to a 800x600 24-bit primary surface (but only blitting to a 640x480 portion of it)). Any ideas/viewpoints on the matter would be well apreciated. Regards all, Alan.

You can do this by asking your DirectDrawsruface for its DC then calling the GDI function. There is really no other way to do this in DirectDraw unless you want to do it yourself, but I am willing to bet that the GDI will still be faster than what you could create.

CD ROM Information 30-May-02 1:30 30-May-02 1:30  does somebody know if it´s possible get the supported read/write features from about a cd-rom/burner (so infos like supports reading CD-R, CD-RW, Read Speed, Write Speed) and somethin like that ? Re: CD ROM Information Ed Gadziemski30-May-02 11:13 Ed Gadziemski 30-May-02 11:13  Yes. It is possible. Re: CD ROM Information 30-May-02 19:42 30-May-02 19:42  thanx for info, could u give me a small hint why i have to look for like an API or whatever ? Actually i only could figure out how the Check my IDE Controller For an CD-Rom or do the same think via the wnaspi32.dll. But it seems both ways don´t have more information options left for me, so must i read the bios of the cd-rom ?

SetTitle on CDoc class LittleYellowBird30-May-02 1:33 LittleYellowBird 30-May-02 1:33  I'm using SetTitle on a class derived from CDoc, but the title doesn't change. I've tried calling UpdateAllViews(NULL); but it still doesn't change. Any ideas why and / or how I can change the title? Ali Re: SetTitle on CDoc class Michael P Butler30-May-02 1:47 Michael P Butler 30-May-02 1:47  Where in your code are you calling SetTitle? Michael Errata 1: p. 154, section 'Defusing'. For 'red wire' read 'blue wire'. Re: SetTitle on CDoc class LittleYellowBird30-May-02 2:02 LittleYellowBird 30-May-02 2:02  At the end of OnOpenDocument - something like this BOOL CSQMDoc::OnOpenDocument(LPCTSTR lpszPathName) { // TODO: Add your specialized creation code here CString szName = lpszPathName; if (!CDocument::OnOpenDocument(lpszPathName)) return FALSE; InitDocument(lpszPathName); ....... ....... ....... SetTitle(TEMP_FILENAME); return TRUE; } Ali Re: SetTitle on CDoc class Michael P Butler30-May-02 2:09 Michael P Butler 30-May-02 2:09  SetTitle is called by the framework after you've set your custom title by the CDocument::OpenDocumentFile function. So you won't be able to set your title in OnOpenDocument. You could try doing it in CView::OnActiveView by calling GetDocument()->SetTitle Alternativly you could override the default CDocument::SetTitle function and make sure it only sets the title to the value you want.

Re: SetTitle on CDoc class LittleYellowBird30-May-02 3:55 LittleYellowBird 30-May-02 3:55  Thanks for the help, I decided to override the CDocument::SetTitle function and it now does just want I need it to.

It takes an array on points (coordinates) and draw them all at once. mike... thanks. but Polyline only paint points to dc, 30-May-02 1:18 30-May-02 1:18  i want get every point's corrdinates in the line. such as that I have two point:point1(x1,y1) and point2(x2,y2),I want get every points(coordinates) in the line(from point1 to point2). jzhlily Re: Hi,all, I want to paint a bias and never use LineTo(),Because I want get every point's coordinate in the bias.How can i do? jbarton30-May-02 3:54 jbarton 30-May-02 3:54  I'm not sure if this is what you want, but you may want to look at the LineDDA function. It passes all the coordinates needed to draw a specified line to a user defined callback function (it calls the callback function for each pixel in the line).
