Inverting Button Graphics

Audio and Graphics
#1

I was just wondering if it was possible to have button graphics automatically inverted when pressed. I couldn’t find anything on a quick look at the image APIs, though I did see the photoshop filter post (though I realise its probably still in beta, and thus not available).

Cheers,

Mourdos

You talking about inverting color or flipping image

#3

Talking about colour inverting.

#4

Since corona doesn’t have an invert color API and you can’t get rgb pixel data then no but you may be able to apply a tint

#5

Or include an already inverted image as the over image

#6

We were already supplying an over image, up until the point where my boss realised that he needed to invert over 100 images for a set of designs, then he asked me if it could be done programmatically. He’s decided that we shall just use a single inverted button insert.

Graphics keep getting changed every couple of days, at least I planned ahead and made make the folders generic and settable by config >.>

Cheers anyway.

#7

If you create 2 spritesheets one for default buttons and one for over buttons then you only have 1 image to invert. Then combine them into 1 spritesheet Just a suggestion

#8

Would be a nice feature if you could use 2 spritesheets

#9

I could definitely suggest making one sprite sheet with all the of images, I believe that paint.net is perfectly happy inverting only a selection. Have to figure out how to make sprite sheets work, only used normal images so far, I suspect its not too hard.

Thanks for all your help, its been really useful.
