You can eventually use dplug:graphics for that

Perhaps a DUB mismatch that would give different DIP flags.

I copied and pasted the same code that is failing from the file in 
question and put it into that test code.

Putting an int into a ubyte absolutely should error, that is a lossy 
conversion and should not be automatic.

Okay further testing locally, I cannot reproduce.

Of course I still don't think that code is right and should have the casts.

Either way whatever the dmd is, it must not be as recent as thought to be.

Absolutely. I'm a bit anxious about "accidental VRP" now, not 
sure if the checks fluctuate from version to version, or worse, 
depends upon the platform.

It is necessary to write a utility that will insert (x,y) text on the

simple library on D?

Maybe use imagemagick?

https://stackoverflow.com/questions/23236898/add-text-on-image-at-specific-point-using-imagemagick

Handling multiple image formats is generally a complex task that
requires multiple libraries, some of which may not be trivial. Unless
you have a specific image format in mind?

Also, text rendering, in general, is an extremely complex and hairy
problem. At the very minimum, you need a font. If you have a bitmap
font, then it's relatively easy (just blit the characters you need onto
the image with alpha blending). But if you're looking at TTF fonts or
similar, you're looking at the very minimum at using libfreetype to be
able to meaningfully use the font file. Then there's the issue of font
layout, which is language-specific and may require a complex layout
engine like HarfBuzz (which requires libraries with complex
dependencies).

If utility size is of utmost importance, then the ideal case would be a
fixed image format (so only 1 library is needed to process files of that
type) with a bitmapped font (at worst, a 2nd library for reading the
font) for a specific language (so no cross-language layout issues that
requires complex layout engines). Then you can just treat the font
characters as bitmaps and alpha-blend them onto the image. Preferably,
use a monospaced bitmap font so that you can just use a fixed grid for
character placement, and not have to deal with complex font metrics,
hinting, kerning, and all of that complex stuff. For this, maybe look
at Adam Ruppe's arsd library (https://github.com/adamdruppe/arsd) for
some lightweight modules that read common image formats and do some
primitive image manipulations.

I don't actually have an image to image blit function, but 
writing one is trivial - just loop over it and call alphaBlend.

It can load ttf fonts, render them to bitmaps, load images, 
combined them, then save images. Can even load ttfs off the 
operating system if you wanted to use those.... or even have the 
OS functions do the drawing instead of diy, but probably easier 
to diy this simple case.

Sample code would be:

---
import arsd.image;
import arsd.ttf;

void main() {
	auto image = loadImageFromFile("/home/me/small-clouds.png");
	if(image is null)
		throw new Exception("Couldn't load the image file");
	auto tci = image.getAsTrueColorImage(); // convert to rgba for 
simplicity

	import std.file;
	auto font = TtfFont(cast(ubyte[]) 
std.file.read("/home/me/arsd/sans-serif.ttf"));

	int width, height;
	auto bitmap = font.renderString("Hello", 14, width, height); // 
it populates width and height fyi

	// where we want to put it
	int xput = 30;
	int yput = 20;

	int bitmapOffset = 0;

	// color to draw the text
	int r = 255;
	int g = 0;
	int b = 0;

	foreach(y; 0 .. height) {
		if(y + yput >= image.height)
			break;
		foreach(x; 0 .. width) {
			scope(exit) bitmapOffset++; // always advance this as long as 
we're still drawing...
			// but don't draw out of bounds
			if(x + xput >= image.width)
				continue;

			// replace a pixel with the blended version of the text bitmap
			image.setPixel(
				xput + x, yput + y,
				image.getPixel(xput + x, yput + y).
					alphaBlend(Color(r, g, b, bitmap[bitmapOffset]))
			);
		}
	}

	import arsd.png;
	writePng("text-image.png", image); // save it back to a png
}
---


Open the text-image.png to see the result. (Or:
---
     import arsd.simpledisplay;
     displayImage(Image.fromMemoryImage(image));
---
to display it in a window right from your program!)



My libs are available as individual files from the github - you 
might just use png instead of the whole image.d to avoid needing 
additional files for formats you don't need - or you can pull it 
on dub under the arsd-official:image_files package and 
arsd-official:ttf.

Try passing the `-i` flag: `dmd -i app.d`. This way, imported 
modules are actually compiled and linked too. Currently it looks 
like you import arsd, but then don't link the library, so it 
complains about undefined references to functions in arsd.

How small did it get?

And with my libs if you import the other ones like `arsd.png` or 
`arsd.jpeg` directly instead of `arsd.image` that MIGHT help trim 
it down by removing support for other formats.  I'm not sure 
though, none of them are especially big but it might add up.

Yes, just now, on your advice, I did so. The size has become a

what stb is for C.

I think in the first time running any D compiler, it should blink 
in the terminal in Yellow/Pink or whatever color you like, and 
show some info like: Are you starting a new project any need some 
libs? Do you know about arsd? If not then go to:

tbh sometimes i just don't feel like answering messages. even 
this one, i was like "i can do that easily, but do i want to 
support another user?"

but meh i had a few mins to kill anyway

 For me arsd is for D what stb is for C.

Note that a few of those modules are stb ports over to D.

I wrote the png and bmp modules myself, for example, but the jpeg 
is a port from C (that port done by ketmar on irc) and the ttf 
one is stb_ttf ported to D then with a little wrapper struct 
pasted on top.

One thing I'm kinda proud of though is my OperatingSystemFont 
class in simpledisplay which can load a font and then pass it 
into the ttf thing and/or the nanovega module for all kinds of 
custom effects. You don't necessarily have to package your own 
ttf files!
