Can Gideros load the highest res image available instead of the base one?

speeder_kidoteca

Suppose I made a app that supports normal images, then @2 and @4.

The manual says that if a higher-res image is not found, it will load the base image.

But suppose I have a image that has the base, and @2, on a device that requires @4, it will load the base one, or the highest available one? (@2)

SinisterSoft

That would be the better solution imho.

speeder_kidoteca

Wait what?

If I understood, what I said (loading the highest version available) is something that not even occurred to the team?

SinisterSoft

I don't think so (I'm not part of the team, so I don't know specifically).

Either that, or you assume a lot of things without waiting for a proper answer from the team?

Noup, just checked, and it takes the base image. Currently I don't know the reason behind it, but if you would want to make it behave the way you said, you could probably use @2, base and @0.5 ratios

SinisterSoft

It would be better to use the higher resolution images, maybe it's just an oversight and will be fixed in 2.0

speeder_kidoteca

Then can someone invite the team to take look at that?

@Mells

Because the way SinisterSoft replied, and his post story, I assumed he was a employee... I e-mailed already the owner using the contact form stating that his site is terrible in the sense it does not say anything at all about the company, beside the name (and the address in the contact form).

Currently I found no way to figure who is a employee or not, or the history of the company, or anything like that.

It is bad because it smells very unprofessional, and the business side people here are kinda irked by it, but I decided to insist anyway and test gideros on its technical merits.

SinisterSoft

I don't think my reply ( "That would be the better solution imho." ) sounds like something an employee would say. Sorry if I gave that impression. :-O

The Gideros website is improving everyday, to me it looks really professional - eg looks similar, if not better, that it's nearest competitor (CoronaSDK).

I agree with you.
Btw your portfolio of apps is interesting.

@SinisterSoft

The site visually is very good, I visited it before it was changed, and it is looking great.

But a site is supposed to give useful information, not only look great But it certainly is going on a good direction.

@Mells

Oh, thanks

Another question: what if the base file is absent, so only the @2 file there? Would Gideros load the @2 file then shrink it down by half on a device requiring x1; and not scale at all on a device requiring x2?

ar2rsawseen

Base file is mandatory, even if you will have the proper @2 image but no base file, gideros will give out File not found error.

I'd like to know more about exactly what Gideros does when choosing a resolution. Let's say my base resolution is 320x480 (iPhone) and it runs on a device with 480x854. Thats a scaling factor of 1.5 in x-direction and 1.779 in y-direction. Lets say I have x1.4 and x1.8 graphics sets. Which will it choose?

john26

Ha! Just noticed I'm on the top posters list for the first time! <:-P

ar2rsawseen

@john26 Congrats
On your question, it also depends on the scaling mode you enabled, for example letterbox will have the same ratios thus, scaling factor will be the same for both axis.
But you will have to wait for @atilim to get to know more on this

john26

I was thinking of stretch mode...

Ha! Just noticed I'm on the top posters list for the first time! <:-P </p>

now go for @techdojo's shiny star

john26

Thanks, @hgvyas123! I doubt I will catch him unless I write a script to generate random comments :-)

But back to the original question, can anyone explain what magnification would be applied given the above scenario...?

The best idea is to play with automatic image resoulution example in gideros installation directory as it behaves differently according to scale factor and resolution from my understanding if we choose letter box it will take device's width (in portrait mode always) for calculation and if we had stretch it will take device's height so for your case it will take x1.8 images but still play with example to get better understanding

john26

OK, thanks, I'll experiment and see what it does. It would be nice if staff could comment however... This whole issue needs to be clarified in the docs as it is pretty crucial!

We'll implement loading the next high resolution image instead of base.

I'd like to know more about exactly what Gideros does when choosing a resolution. Let's say my base resolution is 320x480 (iPhone) and it runs on a device with 480x854. Thats a scaling factor of 1.5 in x-direction and 1.779 in y-direction. Lets say I have x1.4 and x1.8 graphics sets. Which will it choose?

Currently the formula is calculating average scaling by

scale = (scaleX + scaleY) / 2

and choose the nearest graphics set.

In your example, the scale = (1.5+1.779)/2 = 1.6395 and it's near to 1.8 therefore Gideros will choose 1.8x.

Also I'm open to suggestions like scale = max(scaleX, scaleY) or scale = min(scaleX, scaleY).

john26

Thanks for the info. So to continue the example, having decided on 1.8, Gideros would load the 1.8 graphics and scale them by 1.5/1.8=0.833 in the x-direction and 1.779/1.8=0.988 in the y-direction?

atilim

@john26 exactly.

techdojo

Thanks, @hgvyas123! I doubt I will catch him unless I write a script to generate random comments :-)

That's a bit harsh (true maybe, but harsh all the same)

john26

The thought never crossed my mind ... :-\"

speeder_kidoteca

I can code and sell to you a markov chain generator, want it? :P

bysreg

so is this feature already implemented in the latest gideros ? because i tried to optimize my high-res apk so that it doesnt contain any normal-res images. but it seems the base image is still needed. Couldnt gideros only needs the high-res image for the high-res device? it would save the apk size a lot

ar2rsawseen

@bysreg do you mean like, exporting specific android project only for high res devices?

Because apk file can not know beforehand on which device it will be installed.

bysreg

@ar2rsawseen

yes. I know. I will export the android project for high-res device and adjust it in the manifest so that it will only support the high-res device. Meaning, high-res device will only download high-res apk in the google play store
