Yes, there are conversion tools, but that does not necessarily mean that

depending on the algorithms the tool uses it might even depend on the

I think Graeme's question about storing DPI in .lfm files might be relevant.

As an aside, I've been working on setting up a "cheap" TV as a 3K

Would you mind elaborating on this ?

I wrote an app which is DPI aware (as per the instructions on the Lazarus wiki).

It worked on Linux, Windows 7. Then someone ran it on Windows 8 and 10, 
and those versions of Windows did something which completely messed up 
the DPI awareness. I believe it has something to do with the manifest, 
but I didn't have time to investigate it yet :(

All I know is: It's DPI-Aware. Normally, that should cover most cases.
I do not know if it is multi-monitor DPI aware.

To be correct, in early versions of Delphi, DPI-Awareness was severely broken.
So much so that we had to disable it in our applications.

That's just the tip of the iceberg - what about multi-head systems where
each monitor has a different DPI value. Such system are very easy to
setup (and least under Linux or FreeBSD) and quite common - at least in
developer circles. So how does LCL's "Screen" or "Application" object
report DPI values then?

Strange, because using the same method as what you, but with a fpGUI
test application. Scaling worked perfectly on Linux, FreeBSD, Win2000,
WinXP, Win7 and Win8.1

Here are screenshots I just did under Windows 8.1. The application was
designed at 96dpi, and I tested with 120 (120%), 144 (150%) and 192
(200%) dpi values. Note how the whole application stays in proportion
with clear text and graphics.

  http://geldenhuys.co.uk/~graemeg/temp/


Granted, under Win8.1 I had to include a manifest file to tell Windows
that my application is DPI-aware, otherwise it does scaling (app stays
at 96dpi and then Windows zooms the app). Here is the manifest file I
used, as as recommended by Microsoft.

Use SVG directly and let it render the correct size at runtime. That
will solve the problem for any dpi value. Higher resolution images will
only solve the problem for hard-coded dpi values like the Microsoft
ones... Think Android phones and tables, where every devices has a
different DPI value and they vary greatly.

Break it down into manageable steps:

1. Add SVG support to LCL, but keep BMP & PNG support too.
2. Change the high-visibility icons to SVG first.
   eg: the ones on the main toolbar.
3. Then as time permits (or contributors help), go through the menus and
   dialogs one by one.

It may be the last problem, but it can be worked on independently, so
volunteers can already start.

Normal icon sets are about common topics. Most Lazarus icons are
hard to map to such icons, because they are either about specific
graphics (e.g. TDBListBox, TMySql51Connection) or about abstract topics
(jump to implementation).
So you need a good deal of custom icons.

Bad quality icons totally ruin the look of any application. End-users
would be pretty darn disappointed as they judge every app visually.

Just as was done before (a couple years ago), when all Lazarus icons had
an overhaul. Nobody expects a single volunteer to do it all. Before we
had many people, myself included, chip in and create a few icons at a
time. After a couple weeks or months, they were all completed.

Exactly correct. This was a known problem from 3+ years ago (I remember
reading about it years back). Canonical changed something in Unity's
tray area, and it broke loads of applications using the tray area. A
quick internet search will reveals stacks of reports on this.

When I worked with Delphi, VCL's DPI support was broken and a the
retailer's support was frustrated when people kept asking about it.
I don't know about the latest situation. Maybe FireMonkey has solved it better.
Anyway, I think we should solve it despite of how VCL behaves.

In bug tracker there are 9 issues with tag HighDPI. The real number of
high DPI issues is much higher. For example this one has many related
issue marked :
  http://bugs.freepascal.org/view.php?id=14688

Somebody should take initiative. I personally don't know what exactly
must be done to fix things.

One important part of HighDPI would be scalable icons. Sandro
Cumerlato had an idea of SVG support for LCL and the whole IDE, but I
have not heard of him or his plan for a while.
SVG support sounds very good. In fact it is becoming a necessity with
all the high resolution gadgets.
I have followed KDE project's development over years. They switched to
SVG graphs already > 10 years ago and yes their GUIs look good.

Who would step in and implement SVG support. I believe Sandro would
join if there are other people involved.

Juha

What do you think about

I had seen this article already, which is why I also think that SVG is not the 
way to go.

Basically, the only excuse for using SVG for icons, is lack of time.

Delphi 10 Seattle (the IDE) is severely broken - everybody on Google+'s
Delphi community is complaining about it. All the IDE dialogs are
broken, and Embarcadero has no solution yet. There first attempt at a
quick fix was broken too.

I don't know if this link will work, but here it is:

  https://plus.google.com/communities/103113685381486591754


I believe your own application will work correctly and VCL is multi-head
aware. I don't have Delphi 10 Seattle, so I couldn't test myself.

I don't use the designer at all (no LFM files). I create every visual

scaling. This approach slows down a little bit the design but I have to 
say that I am very happy with it.
Actually everything I do is that I use a scaling factor for every 
control I place on the form. Something like:

Button.Width := ScaleMe(100);
Button.Height := ScaleMe(20);
And yes, I use manifest with DPI awarness enabled.
Easy and works like a charm. I have not added support for multiple 
monitors with different DPI yet, though. But this shouldn't be a big 
problem. You just have to know that the form moved to another screen and 
scale every control appropriately.

In VCL, it is possible with manual approach: 
https://community.embarcadero.com/blogs/blog-menu/entry/how-to-guide-upgrading-your-delphi-vcl-applications-to-support-4k-displays

(Works pretty well.)

I don't know the state of the art of FireMonkey, though. The last time I 
checked it was broken. And since FMX should be scalable by design, this 
was a NO-GO for me. So I switched to LCL :)

Maybe the V in SVG stands for vector, maybe not.

I fully agree with that. I'm actually busy doing exactly that in fpGUI
too. I want the default icon set to be SVG only. AggPas (the new fpGUI
graphics backend) has excellent SVG support. AggPas is included with
Lazarus too, so that could be used there as well.

On a side note:
 I experimented in fpGUI using FontAwesome too - yes, the web technology
for scaleable icons. That works very well in fpGUI too. :) Though I
still think SVG is the better option.

IMO the icons are the latest problem. Personally I don't care if the 
icons are blurry at higher DPI. It would be absolutely sufficient that 
every window and control in the IDE is properly scaled and images are 
resized with quality loss.


Maybe the best solution would be to buy a professional set of icons (via 
some fund-raising e.g.). I don't think there is a volunteer who would 
make 400+ icons for Lazarus...

OMG - a 38 page guide! Are they joking. I used about 20 lines of source
code and my fpGUI apps scale perfectly. The same method (and very
similar code) can be applied to LCL too. Bitmap images/icons are the
only thing that needs a bit more attention (to keep them sharp), and
that is where SVG comes in.

I'm well aware of the fact [issue] that large icons normally use large
detail and small icons should use less. But that comes down to the fact
of how the designer designs the icons. KDE and Gnome generally show that
a single SVG file can suffice - by sacrificing on "intricate details" is
the design.

Bottom line - the SVG solution is a lot better that shipping say Lazarus
with its 400 icons in 15 different icon resulutions. That ends up with
6000 image files, which is crazy.

I already detest Lazarus's default application icon, which comes in at
140KB - larger than the source code of all my "quick test apps".

They way displays are improving, 16px, 32px graphics will soon go by the
way of the DoDo. The smallest resolution images on a 300+dpi (4K plus)
display will probably end up being much larger than we see now, so the
scaling of image detail should not nearly be as exaggerated as that
article implies.

I don't presume to know the details of the SVG file format, but I
wouldn't be surprised if it includes some reduced (optional) detail on
low resolution rendering. If not yet, then a future extension of the SVG
file format. Maybe the issue is simply that not all SVG viewers are
created equal - some don't support all the features of a SVG file?

I disagree with you. First we dont need 15 different icon set, just few
for every DPI something like Android that for our case it will be about
5 more or less. Second we can use SVG and its better but we can make 2
set one detailed and one simple. Designer will do it simply. Third many
icons will not a problem for an IDE.With this way we can run Lazarus
even in a mobile or a TV!

So I think after solving DPI aware IDE we can find someone to make new
set icon with SVG and PNG export for different situation.

In our company we do the icons for each resolution by hand and it
definitely makes a notable difference whether the icon is downscaled from a
detailed one or handcrafted with less details.

The .ico file format supports multiple resolutions.

On Windows you can only use .ico files for application icons and the
default icon is supposed to look good in all zoom levels of the explorer...

Re: [Lazarus] lazcontrols filters

What do you think about moving TextHint related things from TCustomEdit
to TWinControl to make TextHint available for all TWinControl
descendants, for example TComboBox.
In this case developers may have unified look of controls on a single form.
Anyway TextHint for ComboBoxes would be welcome.

There are currently about 400 icons in the IDE.
We need volunteers to create them either as SVG or as higher resolution
image.


is there not a conversion tool that can convert them from what they are now 
(raster??) to SVG format?


a quick look shows there's various ways but it seems that many simply embed the 
original image within the SVG output... the good ones that work seem to be 
manual (eg: inkscape, adobe illustrator)...

Re: [Lazarus] Tray icon not working on Ubunut

[Anthony Walter]

In the future one thing we can do, if the desktop environment is popular
enough (I'd argue that Ubuntu is the most popular Linux for desktop users
distribution) is:

* Make a note of the problem
* Provide links to resources where people could start if they want to work
on a fix

Regarding point #1, on this page I see nothing noting the problem, even
though it;s been in existence since Unity was made the default interface in
2011 (more than four years ago):

http://wiki.freepascal.org/TrayIcon#Help.2C_Bug_Reporting_and_Feature_Request

Regarding point #2, here is some information which we could maybe link to
in the wiki or some other place of prominence:

It would be Delphi incompatible.
AFAIK TextHint is introduced in TCustomEdit there.

You /do/ know that a part of SVG is also the file format, namely XML? Why
invent something new when it's already there...
(And yes, resources can store arbitrary files)
