Вот пишу я тут кое-что для Windows - понадобилось использовать [ GDI+ | Gdiplus | Gdip | GDI Plus ] - а его и нету!
Да мне и не нужны обёртки в виде всяких классов/интерфейсов, мне нужен только Flat GDI+! Объявления типов, макросов и функций. И всё!
Это же часть WinAPI! Почему нету заголовков?!

Hello MinGW2018,
Welcome to the forum.

OP's post translated using Google Translate:
Quote
Here I am writing something for Windows - I needed to use [GDI | Gdiplus | Gdip | GDI Plus] - and it's not there!
Yes, I do not need wrappers in the form of any classes interfaces, I need only Flat GDI! Declarations of types, macros, and functions. And that's it!
This is part of WinAPI! Why are there no headlines ?!

Maybe this links can be useful for you:

Please, add it into LCL!

Потому и нету (я так думаю), что код который работает только на Windows, для Lazarus (являющийся кроссплатформенным) являет малую ценность/приоритет. Так, только в качестве дополнения, в частном порядке, и уж никак не в LCL.


Handoko дал тебе ссылки на темы, там есть вложение .rar, обнови, дополни, выложи, поможешь другим заинтересованным.

P.S. А зачем тебе вообще gdiplus?

It is not. "GDI" is winapi, GDI+ is an additional library introduced with Windows XP.

GDIplus mostly adds some multimedia handlers, and is notoriously slow and buggy. What is so crucial in GDI+ that you need it? And why don't you just use it together with the GDI backend, why must the whole backend be GDI+ (which IMHO is not very realistic)

The LCL is a GDI backend library.

(I assume you mean this attach: https://forum.lazarus.freepascal.org/index.php/topic,22085.msg129802.html#msg129802 )

So what that it is old? So is gdiplus?

that old attach works perfectly for me. I'm using it to add support for gdi+ in a number of components. Did you tried it and had problems?

It is not "additional", it is "OS subsystem". Yeah, it is "new library introduced...". But it is OS part. Just new part. Like "Userenv.dll", like "Magnification.dll", like "Advapi32.dll".
Contrariwise, function AlphaBlend() or GradientFill() is not part of GDI32, it is from additional library "Msimg32.dll" introduced with/for IE. But it is declared in Lazarus.


Didn't get your words about together/realistic, sorry.

and is notoriously slow and buggy.

erm... GDI+ is not slow. GDI32 is slow. I have checked. Also, GDI+ supports highest quality than GDI32.
I have ever faced the only one bug: with GdipCreateHBITMAPFromBitmap() from a JPG image.

So what that it is old? So is gdiplus?

GdipBitmapConvertFormat() - not declared.
GdipBitmapApplyEffect() - not declared.
GdipDrawImageFX() - not declared.
GdipCreateEffect() - not declared.
e.t.c.

Well, afaik gdiplus was meant to be the graphical backend of Winforms originally. That's why it contains duplicates with GDI while those other subsystems that you name do not.

If you look carefully, it is declared in Jedi libs, not in the core headers.

I do have to confess most of my experience was from XP times.

Anyway, I checked if there is a 3rd party Delphi project that translated the header, but unfortunately it has an incompatible header (BSD with advocacy clause). http://www.bilsen.com/gdiplus/index.shtml

I just re-discovered that "agile" is worthless: have to be an old hand to save a project at a bank. Everybody knows "agile" is nonsense, just not CEO's and CTO's.

So... Let's paraphrase my "Please, add it into LCL!" as "Please, add it into Jedi libs!":D

Also, I can't find a lot of "Interfaces" in Lazarus... For example, IShellItemImageFactory...

..., but unfortunately it has an incompatible header (BSD with advocacy clause). http://www.bilsen.com/gdiplus/index.shtml
Thanks! A'll check it!

I did one for KOL. Still works.
Is it "GDIPVER>=0x0110"? Where can I get the latest version? Thanks!

There isn't any and I will not update it. But it still works. It is highly stable even on Windows 10.+
Reason: Time and lost interest in KOL -because Vladimir Kladov dropped development and support -. Although I will answer KOL questions....
