DDigit v1.06 Text Rendering Pack For Plugin Writers, 30 Mar 2015

[StainlessS]

A VERY minor mod to InfoF.h, the Info.h companion for printing
formatted text, no real need to change it but here it is anyway.

These are the lines as they were:

	const unsigned char *se, *ss;			        // unsigned
	for(ss=(unsigned char*)s; *ss; ss=se) {		        // while, some to do
		int n;
		for(se=ss; n = *se, n>=' ' && n <= 223; ++se);	// Find end+1 of printable
		int len = se - ss;				// Len of printable
		if (len) {					// Some to print
			DrawStringPlanar(dst,x,y,(const char*)ss,len);

And here is the entire mod:

void  __stdcall DrawFStringPlanar(PVideoFrame &dst,int x,int y,const char *s,bool pix = true)
{ // Draw formatted string at pixel or character coords, pix == false = character coords
	if(pix == false) {x *= 10;	y *= 20;}		// To Chars
	int in_x = x;						// REM x for '\r'
	const unsigned char *se=(unsigned char*)s;	        // unsigned
	while(*se) {						// while, some to do
		int n;
		for(s=(char*)se; n = *se, n>=' ' && n <= 223; ++se);	// Find end+1 of printable
		int len = (char*)se - s;			// Len of printable
		if (len) {					// Some to print
			DrawStringPlanar(dst,x,y,s,len);	// do the biz
			x += len * 10;				// update x coord
		} else {				        // Ctrl code OR nonsense;
			if(n == '\n') {
				x = 0; y+=20;			// Newline, down 1, LHS
			} else if (n == '\r') {
				x = in_x; y +=20;		// Newline Special, Down 1, orig x coord
			} else if(n == '\b') {
				x -= 10;			// Backward Space
			} else if (n == '\f') {
				x += 10;			// Forward Space
			} else if (n == '\t') {
				x+= ((4*10)-(x%(4*10)));	// H-Tab (step 4)
			}
			++se;	// skip ctrl code (and unknowns, outer loop detects nul sentinel)
		}
	}
}

void  __stdcall DrawFStrPlanar(PVideoFrame &dst,int x,int y,const char *s)
{	// Formatted Print @ character coords
	DrawFStringPlanar(dst,x,y,s,false);
}

The mod just saves a bit of swapping about of pointers.
The above code is for the Planar rendering function only,
amend the other 3 also.

EDIT:- shall within minutes of this edit, add (above modified) "InfoF.H"
to the 1st post for those that might want to try the companion header that
allows formatted print at both pixel and character coords via the standard
Info.h, (of course no color control is possible). Just include the
InfoF.h header after Info.h and call the InfoF.h functions when
either character or formatted print is required.

Is there any chance that a moderator could at some stage, approve the
2nd attachment in the first post, if there seems to be a problem, I could
always delete it, (or save me the bother and do it yourselves).
About 7 days waiting now. ta.

About 7 days waiting now. ta.

Done.

DDigitTest.dll & DDigitTest26.dll with source, update, see 1st post.

Complied for Avisynth v2.6.

YV411 looks pretty awful with color (as expected).

[StainlessS]

v1.05, DDigitTest.dll & DDigitTest26.dll with source, update, see 1st post.

Complied for Avisynth v2.6.

Implemented additional 16 Greyscale print colors.
YV411, optionally prints only luma channel and ignores chroma. (looks better).

[StainlessS]

DDigit v1.06 with DDigitTest.dll and DDigitTest26.dll with source, update. See 1st post.

[StainlessS]

DDigitTest (DDigit test dll) v2.6 dll recompiled with Avisynth Version 6 Header.
See 1st post.

No version number increment, uses same version No as DDigit (v1.06).
