Hi,
I use lua, Iup, could use iup.plot, iup.glcanvas.
I think GL is available here.
But failed to use GL in CD canvas.
Environment:
- lua 5.3.4.
- CD 5.14.
- Windows 10 x64.
- Intel Core 7th-i5 Graphics 620,
+ AMD Radeon Graphics.
Use iup.glcanvas to check version.
```lua
local iup=require'iuplua'
require"iupluagl"
local GL_Canvas=iup.glcanvas{
map_cb=function()
print("GL_Canvas.map_cb")
end
}
local Dialog=iup.dialog{
RASTERSIZE=nil,
GL_Canvas,
}
Dialog:show()
--after map
print("GL_VERSION="..iup.GetGlobal("GL_VERSION"),
"GL_VENDOR="..iup.GetGlobal("GL_VENDOR"),
"GL_RENDERER="..iup.GetGlobal("GL_RENDERER"))
-- 4.6.0 - Build 27.20.100.9664 Intel Intel(R) HD Graphics 620
assert(iup.GLIsCurrent(GL_Canvas))
assert(not GL_Canvas.LASTERROR and not GL_Canvas.ERROR)
```
Failed when use CD
```lua
local CD=require'cdlua'
require"cdluagl"
--print(CD.ContextCaps(CD.GL))
local CD_GL_Canvas=CD.CreateCanvas(CD.GL,'400x300')
assert(CD.Activate(CD_GL_Canvas)==CD.OK)
assert(CD_GL_Canvas:GetAttribute('GLVERSION'),"GL is not available")

Hi, Most of my answers regarding BC6 will be I don't know. I haven't built IUP/CD libraries for BC6 for a long time now. I don't even have it on my system installed anymore. When we built CD for BC6, I recall that compiling code that uses GDI+ was a problem. Probably that's why you couldn't find a cdcontextplus.lib file on the distribution. Notice that IUP and CD evolved a lot since the version you are using... > I've done all that actions according to several ways described in manuals to build from source. I apologize, maybe I should read the manual more carefully before asking a question, but at glance, I didn't get what I've done wrong. Sorry, our build system is not very flexible in Windows. We are moving to CMake, but I didn't have time to complete the move yet. > Next, I've created BC6 static library project and added files from cd/src/cdcontextplus.mak: That's a good approach. > get a segfault. Aff We may try a different approach, to remove the GdiPlus dependency from iup_plot. I can't remember if the version you are using has this feature, but GdiPlus can be removed by not defining USE_CONTEXTPLUS in the config.mak file of the iup/srcplot folder.

Hello, Dear IUP library developers! I'm looking for a way to incorporate IUP, and especially the iup_plot library as a static library, embedded in Borland C++ Builder 6(BC6). app. The first thing I've done is download binary releases from sourceforge.net: lua-5.1.5_Win32_bc6_lib iup-3.14_Win32_bc6_lib.zip cd-5.8.2_Win32_bc6_lib.zip And make a test project, that linked to: cd.lib cdgl.lib cdlua51.lib freetype6.lib ftgl.lib iup.lib iup_plot.lib iupcd.lib iupgl.lib iuplua_plot51.lib iuplua51.lib lua5.1.lib zlib1.lib However, the build fails due to iup_plot.lib external symbol cdInitContextPlus. Skimming through cd libs sources led me to belief that cdInitContextPlus must be in cdcontextplus.lib (folder cd\src\gdiplus) for Win32. I couldn't find that library prebuilt for BC6 in binary releases from sourceforge.net I've tried to build library from sources, to do so I've accomplished several actions: 1. download tecmake, extract to C:\tecgraf\tecmake, added C:\tecgraf\tecmake to PATH env.var., tested that tecmake.bat is in sys path 2. changed tecmake.bat ``` set TECMAKE_PATH=c:\\tecgraf\\tecmake set TECMAKE_MAKE=gmake ``` set env vars: ``` BC6=C:/Borland/CBuilder6 TEC_UNAME=bc6 ``` 3. installed gnuwin32 (https://sourceforge.net/projects/gnuwin32) 4. rename make.exe to gmake.exe, add gmake.exe path to sys path 5. download cd-5.8.2_Sources, extracted to C:\tecgraf 6. run cmd and: ``` Microsoft Windows [Version 6.1.7601] (c) Корпорация Майкрософт (Microsoft Corp.), 2009.

After that I was able to add compiled static lib (and gdiplus.lib produced by implib (BC6 util) from my system gdiplus.dll) to test project but and, at last, get a segfault. gdiplus.dll located at c:\windows\winsxs\x86_microsoft.windows.gdiplus_6595b64144ccf1df_1.1.7601.17514_none_72d18a4386696c80\GDIPLUS.DLL I believe there is a gdiplus.dll version encoded in that path above. Segfault will not happen if I didn't call luaopen_iuplua_plot (e.g. comment out line 83 "luaL_requiref(L, "iuplua", luaopen_iuplua_plot, 0);") so libs related to plot wouldn't be statically linked. Segfault happens during startup, looks like the reason is a startup initialization of some global variable. I'm definitely doing something wrong. Is there any way to get precompiled cdcontextplus.lib for BC6, could you kindly point to what I've done wrong with building from source, maybe a manual paragraph that describes what I've must do to achieve build from source? Is it possible for bc6 to use iup_plot? Can last libs versions (iup 3.30) be compiled with BC6 as stated in manual? Is it possible to get an archive from build system for BC6 or some examples of building IUP from sources? I would be glad to get any advice (even that I shouldn't use BC6 in 2021). I've uploaded two described BC6 projects just in case: https://disk.yandex.ru/d/ElfVaII7k09GgA https://disk.yandex.ru/d/-bVaKZZJlXOgTA Best regards, Sergey |

Yes, but as I said, it depends on the application. Some applications define the size of the text and then the lines must align to it. If yours the text must align to the lines, then yes, you should use font sizes in pixels. To use font sizes in pixel you can specify negative values in cd.CanvasFont. To manually convert points to pixels you can use canvas:MM2Pixel(mm_dx, mm_dy) I tested this, on your sample and returns ok: print(cdbCanvas:MM2Pixel(12/cd.MM2PT, 12/cd.MM2PT )) 32.0 32.0 Best, Scuri Em ter., 24 de mar. de 2020 às 20:49, Milind Gupta <mil...@gm...> escreveu: > Yes this one does not have scaling because I was just doing an example to > check proportionality. > > So what I understand is to be consistent across different canvases where > pixels/mm are different I should internally store the size of text I > display in pixels?

Yes this one does not have scaling because I was just doing an example to check proportionality. So what I understand is to be consistent across different canvases where pixels/mm are different I should internally store the size of text I display in pixels? That way when I implement scaling it would be on pixels and remain consistent. But when I tried to convert the pt size to pixels I am not having good results. For example to convert 12 pts to pixels I did this: cd.MM2Pixel(12/cd.MM2PT, 12/cd.MM2PT ) But this returns 0. How do I translate this?

For example the screen shows the graphic as: [image: image.png] While the printout shows it like: [image: image.png] The text gets totally out of proportion to the rest of the drawing compared to the screen for the same size.

Actually the problem is the scaling is not the same on the screen compared
to the printer. So the issue is if I scale the drawing and the text
proportionally to fir the number of pixels the text gets much more larger.
To understand that if you just run the script and see how it looks
on the screen compared to on the printer you can see that the scaling of
the text and the graphics is not proportional. The text ends up much larger
in printer than on the screen.

Hi, That's expected. The PDF or printer canvases have a resolution much higher than the screen. I mean there are much more pixels in the canvas. So things get smaller on output if not properly scaled, text also. The approach depends on the application. Notice that applications are starting to have the same problem on screen when the user has a 4k monitor. By default Windows will scale all the application output. In the IUP documentation we explain how to avoid that automatic scale, but the the application should be able to display its interface in a high resolution.

Hi Antonio,
When I use cd.PRINTER canvas to print the text scaling is not
coming out right. For example see the the attached file. When I press the
button and press print the drawing shows up in the lower left corner as
expected but the text is quite out of proportion. I am doing this on
windows. It doesn't matter if I use an actual printer or use the Adobe PDF
printer (output attached) the result is the same.
How can I fix the text scaling to be right?
Thanks,
Milind

Hi, Finally I got some time to look at this. You used a CD_IMAGE driver to implement the third buffer. It is ok, but you miss drawing that image on the main canvas. Simply calling flush for that canvas does nothing because it is just a canvas that draws on an image, it does not know that the image must be transferred to another canvas. So, we can solve that in two ways. First you can simply draw the cdImage into the cdbCanvas by calling "cdbCanvas:PutImageRect(cdImage, 0, 0 , 0, 0 , 0, 0)" instead of "cdbbCanvas:Flush()". But when the dialog is resized the image must be recreated so the CD_IMAGE driver. Or you can use the CD_DBUFFER driver that will do all that for you, and the image will be hidden inside the canvas. I attached the two modified samples to illustrates the two solutions.

Hi Antonio,
I am a little lost on how to set this up. I have the following
script where I am trying to make a cdImage where I will put the drawing
which does not change and then I want to use cdbCanvas to draw changes. I
am not able to figure out how to use cdImage as a buffer for cdbCanvas.
What I expect from the script is when I start it, it should show me the
blue lines already from cdImage. Once I press the button then I should see
additional drawing that was drawn on cdbCanvas.

A double buffer canvas such as CD_IUPDBUFFER is actually a CD_IUP that automatically manages an image where everything is draw and this image is drawn in the CD_IUP canvas when flush is called. So, you can do any buffers you want but you will have to manually manage the image using cdCanvasCreateImage and a CD_IMAGE canvas to draw in the image. Notice that your main canvas can still be a CD_IUPDBUFFER.

Hi,
Is it possible to add a buffer to a buffer canvas? If there is a
part of a drawing that rarely changes it can be drawn in the 3rd canvas and
flushed to the buffer canvas before doing the other changes.
