Ugh...Ok, let me see:

VRV format (Verve images)

BANK 1 (individually compressed)
bytes -> content
0-21 -> header: "Verve Painter version"
22 -> current version: 14
floats now...
width
height
color[4]
gamma
color midpoint
light color[3]
light position[3]
ambient color[3]
glossiness
background color[4]
depth
current brush size
brush sizes[9]
brush bristle count[9]
brush bias[9]
mouse speed
bytes
mirror mode
high quality mode
floats
smudge chroma
fludity
fluid sharpness
fluid smudge
drying speed

grid field of view
grid distortion
grid opacity
(int)grid density
grid vpos[3]
grid pos[3]
grid rot[3]

byte
show canvas texture
float
canvas texture strength
canvas texture size
canvas texture bias
canvas texture density
canvas texture stretch
int
layer count
end bank 1 compressed

IMAGE BANKS (layer count)
per bank...
byte
hidden
float
bump
glossiness
diffusion
metallic
opacity
visibility
color[3]
byte
style
float
image data color
width * height * 4
image data material
width * height * 2 (whereby this is bullshit and will be just *1 in next version)
...loops until all layers are compressed in their own bank

end of image banks

The next version will be different, because I will break up the layer images to support large formats!
That's all!

Thank you so much Taron! But.. Are you really sure you described brush vri format? It looks like a structure of your vrv format.

[Taron]

OH, jeez, my brains! Hahaha, yes, that's the VRV... don't know where my head is at!
I'm currently trying to work out the scanline procedure, so ... I do know where my head's at!

OK, hold on...
VRI format (Verve Image Brush Format)

BANK 1 (individually compressed)
bytes -> content
0-18 -> header: "Verve Painter version"
19 -> current version: 14
int
image count
end bank 1 compressed

IMAGE BANKS (layer count)
per bank...bank size = width*height*6 (so wrong) + 87+image name length
float
width
height
UV0.x
UV0.Y
UV1.x
UV1.y
UV2.x
UV2.y
UV3.x
UV3.y
byte
perspective mode
float
brush bristle size
brush bristle count
brush bristle bias
brush oscillator
brush oscillator chaos
byte
brush image mode
paint mode
int
name length
string (bytes)
image name
float
image data color
width * height * 4
image data material
width * height * 2 (whereby this is bullshit and will be just *1 in next version)
...loops until all layers are compressed in their own bank

GREAT!! I very appreciate your detailed descriptions!

In next few days I will do more observations and hopefully try to find a good solution. It looks like I am able to support Photoshop brush files up to CS4 version..

[Taron]

Yeah, that would be pretty amazing.

I have to tell you, though, I'm currently trying to do the whole scanline thing and I feel like a complete idiot, it's crazy. One of those things that make me wonder how I could do any of this, really, it's nuts.

I don't know, if you ever had that, but I'm looking at my code and I see nothing wrong with it, but it does something completely different, like something that should be impossible... it's maddening.

And then... AND THEN... shortly after you realize just how stupid it was...

OK, I got it...next version will have no size limit for saving and loading!

"Support larger image formats" ? !
now that will be a game changer
Wohoooooo!
btw
listening in on this development chatter
is quite fascinating
even if I don't have a clue what it means

Sometimes it is better to take a break and better to sleep on it. You can see your code from a different view by tomorrow morning. Fresh eyes and brain can do miracles!

[Taron]

AH...yes, I got it! It's all solved.
Luckily I did not let it simmer...
...next version will be fun for Stavros!

[Taron]

Yup, it works! Just saved and loaded 3321x4510 ....no problem!

[Taron]

OK, so now the format has changed for VRV (and for VRI).
In both cases the *2 on image data material I commented on is now really *1. For the current versions!
VRV is version 15
VRI is version 2
