Horizontal Filmstrip VU meter

[A Former User]

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!
