Horizontal Filmstrip VU meter

[ustk]

Hmmm something's not clear, do you want the filmstrip to extend horizontally or the VUmeter to be horizontal? not the same thing...

Sorry for lack of info.

My filmstrip image is stitched horizontally. Actually I can't stitch it vertically because the height of the stitched image will be soo huge. It is better to stitch a vertical VU filmstrip image horizontally. You can see the image in the project file.

So the VU meter will be vertical but filmstrip image is horizontally stsitched.

I think this code is for vertically stitched filmstrips. When I swap x & y it didn't work. The solution must be so simple but I can't see it guys.

@Steve-Mohican So swapping x and y should work, have you adapted all other properties (index nb, width, height...)?

[Lindon]

@Steve-Mohican so you want this sort of thing no?

heres the png I use:

not really so big...uses 106 images stacked vertically.. to cover the dB range -100dB to +6dB

Apparently, there seems to be a bug when using Xoffset making horizontal filmstrip unusable...

No, my VU Meter will be like this (vertical):

And my image strip is this (stitched horizontally):

I think so too mate.

[ustk]

@Steve-Mohican So I corrected the bug, but it works using a hack for the Xoffset (it can't be 0, minimum 1). This is because the way the API is made gives a priority to check X before Y.

The way I would do it is

setImage(String imageName, bool isHorizontal, int offset)

Might not break compatibility, knowing that no one could have used a horizontal filmstrip before.
A bool isHorizontal would be 0 in older projects anyway. @Christoph-Hart ?
Working on it...

then I've already sent you a snippet with it working...

@Christoph-Hart Here's a fix that is retro compatible (as long as no one as tried to use xOffset but this shouldn't be the case, otherwise it shouldn't have been broken)
Although before making a pull request, I don't know how to properly initialize the auto img variable, I'm sure I did it dirty...

void ScriptingApi::Content::ScriptPanel::setImage(String imageName, bool isHorizontal, int offset)
{
	jassert_locked_script_thread(getScriptProcessor()->getMainController_());

	paintRoutine = var();
	usesClippedFixedImage = true;

	Image toUse = getLoadedImage(imageName);

	auto b = getPosition().withPosition(0, 0);
	auto img = toUse;

	int w = 0;
	int h = 0;

	if (isHorizontal)
	{
		double ratio = (double)b.getWidth() / (double)b.getHeight();
		h = toUse.getHeight();
		w = (int)((double)h * ratio);
		offset = jmin<int>(offset, toUse.getWidth() - w);

		img = toUse.getClippedImage(Rectangle<int>(offset, 0, w, h));
	}
	else
	{
		double ratio = (double)b.getHeight() / (double)b.getWidth();
		w = toUse.getWidth();
		h = (int)((double)w * ratio);
		offset = jmin<int>(offset, toUse.getHeight() - h);

		img = toUse.getClippedImage(Rectangle<int>(0, offset, w, h));
	}


	if (auto drawHandler = getDrawActionHandler())
	{
		drawHandler->beginDrawing();
		drawHandler->addDrawAction(new ScriptedDrawActions::drawImageWithin(img, b.toFloat()));
		drawHandler->flush();
	}
}

@Lindon @ustk Thank you so much guys. That really really helped me a lot. You saved my day.

Thank you again!
