Image sizes

[MikeB]

I have experimented a bit with the image sizes and resolutions.
It looks to me like it doesn't matter what the image contains.
As soon as I load it into HISE it always has the same file size!

Example PNG 8Bit 400x3000 = 184 kb uncomprimed in HISE is 4687.5 kB
Example PNG 24Bit 400x3000 = 673.6 kb uncomprimed is in HISE 4687.5 kB
Example PNG - blank area 400x3000 = 9kb uncomprimed is in HISE 4687.5 kB

@MikeB images are rendered as bitmap, so since your 3 resolution are the same they end up to have the same size

I have already read here that all images are processed internally in 32Bit.

My question now is WHY?

32Bit are used for HDR shots - who needs HDR quality in his PlugIn ? :-)
Can't you give the developer the possibility to choose for himself?
with which resolution his images are processed and displayed?
E.g. 8Bit, 16Bit, 32Bit
Most pictures are perfectly fine with 8Bit - to give them a 32Bit space
is like standing completely alone in a railway station concourse.

This is a big obstacle

@MikeB No idea...

The Windows Bitmap format 32Bit is certainly a fine thing but has the big disadvantage of
extreme waste of space for a lot of pictures 8 or 16 bit pictures are quite sufficient.

Please @Christoph say that you can do something here.

Yes, thank you - I have read it
But I am pretty sure that most developers here do NOT create iPad apps and need Retina resolutions.
with a simple choice between 4,8,16,32 bit when importing or processing internally
would save a lot of memory.

[ustk]

I think that would be good to have an extra definition in the settings...

[MikeB]

Yes that would be fantastic
Because at the moment HISE reserves an exhibition hall internally for a single desk.
Here, the size of a small sales room or ideally an office room would be perfectly sufficient - wouldn't it?

@MikeB Every Apple computer since 2015 has a retina display and most modern Windows 10 machines too so it's not uncommon to have a higher resolution.

Not sure what the problem is though - the images have to be uncompressed in the memory and this is not a limitation of HISE but computers in general.

I'm already aware of the uncompressed part, Christoph.
But do they have to do this with 32 bit ?
If I have an image that is 9kb uncompressed - an empty area - and this then requires 4Mb of storage space in HISE, then I have to use 32 bit.
then that's a bit of a waste - isn't it.
The problem is that if I want to make a more graphically demanding GUI with 10 images, I have to use a lot of memory.
I end up with 60- 80MB.
With pictures that have an actual size of 600kb.

And the only Mac that has this resolution is the iMac and the MacBook - all the others have the resolution that the screen they are using delivers. And that's also true for the PC. - Doesn't it?

The problem is, do I need 32 bits of memory for an 8-bit image?

Is there no possibility here - to let the developer decide for himself whether he wants to store his image in 8 in an
8bit bitmap memory or whether he prefers a 16bit or even 32bit image - or whether he needs this resolution.

I already use all the possibilities to do this with paint routine, but as a graphic designer, I don't know what to do.
I want not only great functions but also sophisticated graphics.
After all, the eye plays along :-)

So if you can do something at some point so that you can use more images
or maybe have a wokaround I would be very grateful.
