What is Image object? First topic.

[ErtYwek]

Hey Ho! This is my first topic there on the LOVE2D forum and I hope it did not break any rule.
Question as in title. I don't understand why

Code: Select all

local sws4 = string.format("images: %.2f ", love.graphics.getStats().images)

return me 13.00 cause i use only one image which disappear very fast.

Welcome to the forums!

Hard to tell without seeing your code, but Löve uses images for some internal things like fonts. For example, if main.lua just contains this:

Code: Select all

function love.draw()
  love.window.setTitle(love.graphics.getStats().images)
end

the title displays 0, but if it contains this:

Code: Select all

function love.draw()
  love.graphics.print('')
  love.window.setTitle(love.graphics.getStats().images)
end

then the title displays 1.

To answer your question, an Image object is an OpenGL texture with fixed contents. It resides in the GPU memory and Löve contains a reference to it, in order to use it when you ask for it to be drawn. I believe that the CPU side does not hold the pixels.

Hi! Thank you for your reply. But I'm not sure what it means. So I have 1 image and 7 texts in total. Still away from 13. Did rectangle counts as opengl image?

I don't know; from a quick test it doesn't seem to count. Löve may be using internal textures for other things, like mipmaps. Why are you bothered about it?

I think about optimization.
