SGL - win32 made simple!

[henrin]

Hello jj2007,

I never heard about animated PNGs. This format does not seem to be widely accepted, and I am not surprised that GDI+ ignore it.

To test multiframe TIFF images, I used the attached image (probably the only one I have found, and I do not remember where!).

In a previous post I did not attach correctly the message box sample. Here it is.

I do not remember where

http://www.nightprogrammer.org/development/multipage-tiff-example-download-test-image-file/

There are two examples, and indeed I didn't find any others on the wide world web
But they both work fine. In contrast to the GIFs, their PropertyTagFrameDelay is not set, though.

APNG is a different story indeed, not supported by Gdi+, and while it would be theoretically possible to pick a frame from an APNG, it would be a lot of work with a badly documented format.

[henrin]

Make your own multiframe TIFF images!

I just remember few years ago ( today its my birthday  ) I created multiframe images, here is how :

- use ACDSee (my sersion is ACDSee Pro 7)
- select several images
- menu batch image conversion

The last option before conversion starts is for multiframe.

TIP : sample_image64/32.exe does not erase the panel before each image.
Results may be unpleasant if all frames don't have the same size.


It is possible to view multiframe images with ACDSee, as well as with FastStome Image Viewer.

[jj2007]

Happy birthday then 

Re roll your own: Not worth the effort for TIFFs. It's an exotic format anyway, so I guess animated GIFs is enough for 99% of all users. APNG may be the future. I wonder if they have much better compression than GIF, though.

[TimoVJL]

MultiTIFF, remind me a FAX
This example make 3 pages TIFF.

Is this project dead? I download and tried Pelles C 9 give me many errors about missing symbol. I link sgl64.lib correctly though. When I opened the ppj file with notepad it said Pelles C 7.00, is it the reason why it failed? If you still there, please update to latest Pelles C version or consider release the source code, I found only header and a precompiler sgl32/64.lib but no c source file. Thanks 

[henrik]

Hello to every body.
That's true, I was retired for few months, but now back for SGL with a new name (henrik instead of henrin).

The previous version was released with my post of November 19, 2016, and a new version is available here.

New for version 1.3.2 :
- The default font is now the message font (instead of menu font).
- Documentation: minor updates.

The project is still with PellesC 8.00 and the ppj file is :

        PROJECT FILE generated by "Pelles C for Windows, version 8.00".
        # WARNING! DO NOT EDIT THIS FILE.
        #

        POC_PROJECT_VERSION = 7.00

When when switching between 32-bit and 64-bit projects in the same directory, you should :
- update all dependencies
- rebuild the project
 
You can find the development kit here http://perso.numericable.fr/hserindat/sgl/ with documentation and samples.

The source code is available to registered members of the PellesC forum.

Another example of use is PUKABO, a simple and stupid backup program http://perso.numericable.fr/hserindat/pukabo/index.html

[TimoVJL]

Thanks Henri.

With 32-bit library have to use a __cdecl calling convention.
For PellesC 9, the libraries have to recompile, as without it:
POLINK: error: Unresolved external symbol '___get_touppertab' - referenced from 'sgl32.lib(sgl_tools.obj)'.
POLINK: error: Unresolved external symbol '__get_touppertab' - referenced from 'sgl64.lib(sgl_tools.obj)'.

EDIT: sgl project files for V9, using src sub-folder for sources.

[henrik]

OK TimoVJLand cnoob, I'll switch to PellesC 9and look at this.
The calling conventions are OK and I did not get these errors with PellesC 8

[henrik]

The problem appears with PellesC 9. It upgrades the project file (sgl64.ppj) and sgl64.lib cannot be built 

I have rebuilt the project from scratch and it works nice :
- sgl64.lib is built
- no unresolved symbol when building the sample programs with it.

I'll investigate what is the reason and then provide the full package.

For now, the attachement the sgl64.lib for PellesC9

[cnoob]

Hihi, I've switched to Pelles C 7.0 because I saw 7.00 in the project file. It's foolish. But it worked well so far 

[cnoob]

henrik, could you provide a version of SGL for MinGW? I know this forum is for Pelles but I'm using libCello which doesn't work with Pelles now 

[cnoob]

hi henrik, your code is portable. after a little patch I've successfully port it to MinGW to use with LibCello. If any of you want, i will publish my modifed version of henrik's sgl src 

[cnoob]

Henri's code already portable because it's just a thin wrapper for WinAPI. Any compiler has mature enough WinAPI support could compile SGL.

This is what I've done to compile SGL under MinGW64 i686-sjlj 8.1.0 (notice: sjlj, dwarf can't throw exception on non-dwarf aware dll like of Windows):

First, replace _stdcall with __stdcall. Pelles compiles _stdcall just fine but MinGW doesn't. I #define _stdcall __stdcall.

Second, #pragma comment is not understood by MinGW so I've to check each pragma to know which lib SGL depends on, on MinGW there's something like -Wl import bla bla for auto import needed lib but I don't trust it. So far SGL needs: advapi32, gdi32, msimg32, gdiplus, shlwapi, opengl32, glu32 and comctl32.

Third, SGL seemed to support only Windows >= 7. On sgl_debug.c MinGW will throw error WM_GESTURE not defined. It's because MinGW still target Windows ver 0x502 (very old). You've to edit sdkddkver.h and _mingw.h to change all on the define of win ver and nt to of Win7 0x601 (my computer so far, I didn't try Win8, Win10...).

Now it happy compiles and provide libSGL.a (just like your .lib), libSGL.dll and libSGL.def.

All of the example recompiled with MinGW worked except sample_text will crash that I didn't know why. It's run ok with Pelles C's compiled version.
