Loading JPEG as splash

[p0wder]

I found this code here, but without a resource file ...

I tried this in my .rc:

10000 IMAGE "PortableHTTPD.jpg"

The file assembles and links without errors, however the resource file is create with a weird randomish name and the file does not load the splash ...

Also, if I use a font in a resource file, will the font will be 'compiled' with the application? If I use an exotic pixel font and someone uses my application on another pc, will they see the font or not?

Hello,
Bad declare for the resource,
"INVOKE FindResource,0,chr$("SPLASH"),RT_RCDATA"
follow winhelp and you see that
named resource = SPLASH
type of resource = RT_RCDATA
;
This set of fonctions are explain in the masm32 library help file
see Image files functions
              ToutEnMasm

[p0wder]

What is odd, is that the person on the board who supplied the code in an older post, included .asm source, .res, and .exe and all work. however no .rc file ...

Anyways, masm32.hlp and masm32lib.hlp have no ref of findresource. win32api.hlp does, however.
I have changed to :

Code Select Expand

INVOKE FindResource, NULL, 1000, RT_BITMAP

The splash does not load, but I believe that it is assembled with the file [being now 14+kb]. No errors...

[ToutEnMasm]

I am not the person who write this,but i can give you the complete code.

declare the resource like that in the .rc file,

800   IMAGE  DISCARDABLE "texture.jpg" // or other jpg

modify the code like this
replace

MOV edi,EAX
      INVOKE SizeofResource,0,EAX
      MOV esi,EAX
      INVOKE LoadResource,0,edi
      INVOKE BitmapFromMemory,EAX,esi   ;read jpg
      MOV splashscreen_hBmp,EAX

by

invoke BitmapFromResource,hInstance,800
      mov splashscreen_hBmp,eax

you can replace hInstance by NULL or 0
Following is the same code
      INVOKE GetObject,splashscreen_hBmp,sizeof bitmap,addr bitmap
      .....
                                ...
When you have such a problem look at the source code of the function at
                    \masm32\M32LIB\BitmapFromResource.ASM

Here is my code, its still a no go, no errors and still no jpeg loading :/

p0wder.
Would it be possible for you to post the original assembly source file with no mods and the .res file (really need this).

Paul

[p0wder]

here are all of the original unedited files from the 'splashscreen.zip' file.

[ToutEnMasm]

I have tested the code in a SDI none in a dialog box,I don't see the .rc in your source.
I join the sample I have write,it is the full source.
See splash.asm and splash.rc,splash.exe to see the result.

Thanks for the help, but I am just interested in getting the code that i have now working :/

[asmfan]

I always thought that GDI cannot handle jpg but handles bmp...
Why can we treat a jpg as bitmap? I know GDI+ can handle... Am i right?

That's correct. GDI cannot handle a compressed JPEG file.

Either attach it as a bitmap (possibly at a lower colour depth) or use a decompression library. Raymond has posted one here, though personally I haven't tried it.

Cheers,

Zooba :U

masm32 examples include 3 examples using jpegs instead of bitmaps. this code is something that i have without the resource file, thats the issue. you can load a jpeg without a third party library.

[Mark Jones]

you can load a jpeg without a third party library.

Are you saying it IS possible, or are you asking if it is possible?

[p0wder]

 i was just saying that it is possible, there is the code above.
