I am a bit confused here. /F is the font type, right?

That is the resource name. A good example of this is on page 270 (292 of 1236) of the PDF Specification 1.6

Tara14 wrote:
Whatever font is being used must be described earlier in the font dictionary, right?

PDF is written to be read somewhat backward but I believe you will see many different ways of laying the file out. The rules are very confusing and complex in my opinion. My implementation ends up declaring the font descriptor objects toward the front but the resource names get associated with the font descriptors in my Pages object which happens to be toward the end of my file slightly before the Cross Reference and the Trailer. However, you can lay your file out in any way that does not violate the rules in the specification so it would be wrong for me to say yes or no to this question.

Tara14 wrote:
Is (Text) the entire text that is being written to pdf?

Yes (Except for the parenthesis of course). Don't forget to apply PDF escape sequences as described on page 30 (52 of 1236) of PDF Specification 1.6 to prevent string literal characters from conflicting with the PDF file.

Tara14 wrote:
Suppose the text is something from a doc file.

If yes, how does the pdf know which part of the text uses which font and which color?

It is up to you to tell PDF what to render and how to render it. If you don't know how to parse the doc file, you will be unable to tell PDF what to draw and where and with what color etc...

My documents are described in XML so I parse the information that describes the action of drawing each graphics primitive (lines, bezier curves, rectangles, and Text) and then I translate it to a GDI/GDI+ graphics primitive command if drawing to the screen or printing or to PDF postscript that corresponds to the equivalent PDF graphics primitive command if exporting to PDF. If you do not have the information necessary to parse the doc file, you will have to resort to a print driver strategy like some vendors but I'm afraid I have no experience there and would be of little help.

Tara14 wrote:
You mentiond that "Also, PDF will keep track of its graphics state. This means you only need to change the...."
I do not understand this. Please can you elaborate a little.

For example...
If you set the Stroke color to red, all subsequent graphics commands will use red for the stroke color until the graphics state goes out of scope (as described in the specification) or until the Stroke color is explicitly set/changed by you. If the Fill color is set to blue all subsequent graphics commands that use a fill color will use blue until the graphics state goes out of scope or until the fill color is explicitely set/changed by you. etc...

I hope that helps

Thanks a lot for your patience. I am begining to understand quite a lot now.

This is a bit complex and confusing, but I guess the more I read the manual, the better I will understand.

Thank you once again.

Hello,

Is there anyway I can open the pdf from the application one it is created? Shellexecute is not working.

I searched codeproject and found "A simple wrapper to control Acrobat Reader from your application, By seasidetech." but it does not work if adobe is not already open. And I am not able to understand why.

Please help.

Thanks.

I'm not sure what you mean when you say ShellExecute is not working. Once I export my .pdf to some path, I call ShellExecute to display it. This is of course assuming Adobe Reader is installed on the machine using the "open" verb

// Note: pApp obtained via AfxGetApp()
ShellExecute(pApp->m_pMainWnd->GetSafeHwnd(),"open",sPath,NULL,NULL,SW_SHOWMAXIMIZED);

One way is via the Win32_OperatingSystem WMI class. GetTickCount() is only good for about 49 days.

2d array problem in standard C

Hi gurus,

I have a problem here. I have forgotten how to pass a 2D array in a function Sigh | :sigh:

. Normally an int** should do the deal, but no Frown | :(

Here is a sample code:

<br />
#include <stdio.h><br />
<br />
int				g_tab[16][4]=<br />
{<br />
	{ 0x03e0, 0x14a5, 0x0000, 0x0000, },<br />
	{ 0x7fff, 0x6739, 0x4e73, 0x18c6, },<br />
	{ 0x6460, 0x6431, 0x0821, 0x7bfe, },<br />
	{ 0x0000, 0x001f, 0x03e0, 0x7c00, },<br />
	{ 0x7fff, 0x7fff, 0x4631, 0x2529, },<br />
	{ 0x7fff, 0x4a52, 0x2d6b, 0x0000, },<br />
	{ 0x01e0, 0x0260, 0x0340, 0x0140, },<br />
	{ 0x7bff, 0x1ce8, 0x5294, 0x7fff, },<br />
<br />
	{ 0x67ff, 0x14a5, 0x56b5, 0x7fff, },<br />
	{ 0x7fff, 0x6739, 0x4e73, 0x18c6, },<br />
	{ 0x6460, 0x4631, 0x0821, 0x7bfe, },<br />
	{ 0x0000, 0x0000, 0x0000, 0x0000, },<br />
	{ 0x0000, 0x029d, 0x025b, 0x0195, },<br />
	{ 0x0000, 0x0131, 0x00cf, 0x0047, },<br />
	{ 0x0000, 0x01b6, 0x02df, 0x03e0, },<br />
	{ 0x68ba, 0x6660, 0x7c00, 0x3460, },<br />
};<br />
<br />
void Apply(int** tab)<br />
{<br />
	int				y=0, x=0;<br />
<br />
	for (y=0; y<16; y++)<br />
	{<br />
		for (x=0; x<4; x++)<br />

	}<br />
}<br />
<br />
int main()<br />
{<br />
	Apply(g_tab);<br />
<br />
	return 0;<br />
}<br />

I don't see what's wrong with the code, but it crashes when calling tab[y][x]. Sniff | :^)

Can anybody help me and tell me what's wrong please?

Best regards.

Fred.

you need to access array like this,

for (y=0; y<16; y++)
{
for (x=0; x<4; x++)
printf("%d ", tab[x]);
tab++;
printf("\n");
}

If you are going to do that, you might as well make it a void*.

I don't think this should work. In tab1[0], you get tab; but from tab1[1] to tab1[3], they point to nowhere.
