Thank Trixie,

I have tried

SaveDTObject(dtype, NULL, NULL,"RAM:x.JPG",DTWM_RAW,TAG_DONE);

with JPG and PNG, it save well a new file (rescaled) but as ILBM format :(

@LiveForIt
Thank for reply.
I'm using C.

For my program FastView, I rescale picture (JPG, PNG,...) by copying a Bitmap to another (with rescale).

What I would want is from a JPG (for example) to resave a new copy as JPG file.
Do you think that it's possible ?

@Thellier,
thank you,
Yes, I saw DTM_WRITE but I'm afraid that it will change the type of picture...

DTM_WRITE -- Write the selected area of the picture to a file as an
ILBM. If no area is selected, then the entire picture is
saved.

Hello,
I'm looking for a function who can create an image file from a valid struct Bitmap.

Is a function of that type exists ?

Thank you, by advance, for you help



[edited thread title - Chris]

Thanks
Hoping...

Please, don't waste your time with my problem,
we must be not a lot of amigans to have a dual gfx setup...

Just tried the last

NetSurf-gcc-jsoff-1092.lha

but, I have the same problem on my 32bits screen with dual GFX cards.

It still lags and take memory on my Radeon9250 card.

Yes, of course, no problem,
mail me when you have the build ready.

Hi Chris,

1) Just for info, I have encountered a lag problem with NetSurf 3.0 (json and jsoff version)

On my x1000 dual gfx setup (RadeonHD 6670 and Radeon 9250), Netsurf is verry laggy.
Mouse stops to respond for 1 second every 2 or 3 seconds.

I found the problem, it is my dual gfx cards setup.

When I launch NetSurf (1 or many instances is the same) it takes memory on my second cards (Radeon9250) even if my Workbench is on the RadeonHD card.

On the grab below,
the right SysMon shows the initial gfx memory consumption (0mb for Radeon9250)
The left SysMon shows that as soon that I launch one instance of NetSurf (json or jsoff) 8 mb of memory are consumed on the 9250 card.

Edit : Memory is well freed on both cards when I close NetSurf.

When I remove the 9250 card all is fine, NetSurf is fast and surf is nice !

2) Nothing related, but do you plan to support external program by contextual menus like on MUI-OWB ?

Nevertheless, without my second cards, it's very speed and surf is very nice.
Bravo !

Thank you Javier & Mathias

Thank you Samir,
It was a pleasure :)

Hello Context,
Do you have good news about the increase of the ContextsMenu buffer ?

Thank you.
Guillaume

For me, too, it runs very well on my x1000.

Magic : it doesn't work on your SAM440 ?

Very nice video of Freespace, I didn't know this great looking game.
Thank you.

Great, it works !

To copy in another Bitmap, I use

p96AllocBitMap and BltBitMapTags for no-alpha pictures

and

p96AllocBitMap and CompositeTags for alpha pictures
(some vertical lines with compositetags and no-alpha picture)

Iconification/deiconification works now (without the need of InitChange/ExitChange)

As usual, thank a lot Thore for your great help and for your availability for MUI (and C) newbies.

Thank you,
it's true that I dispose the DTobject just after to have load the Bitmap Object.

I will try to copy Bitmap with

p96AllocBitMap
and
CompositeTags

I create the MUI_Bitmap by passing to it a Bitmap struct created by Datatype.
You think that the struct Bitmap bitmap_vignette could be corrupted when I iconify/deiconify, it's ?

In my global variables :
struct BitMap *bitmap_vignette = NULL;

In my GUI build :

Child, Im_Data_bmp = BitmapObject, MUIA_FixWidth, 300, MUIA_FixHeight, 225, End,

and I load the Bitmap into this BitmapObject with.

loadVignette();

Object *dtype = NULL;
...
dtype = NewDTObject(nom_fichier,
PDTA_DestMode, PMODE_V43,
PDTA_Remap, TRUE,
PDTA_DitherQuality, 1,
PDTA_ScaleQuality, 0,
TAG_END);
...
res = GetDTAttrs(dtype,
PDTA_BitMapHeader, (ULONG)&bmh,
TAG_DONE);
...
res = GetDTAttrs(dtype,
PDTA_DestBitMap, &bitmap_vignette,
PDTA_BitMapHeader, (ULONG)&bmhd,
TAG_DONE);
if ((bitmap_vignette != NULL) && (res == 2))
{
SetAttrs(Im_Data_bmp, MUIA_Bitmap_Width, 300,MUIA_Bitmap_Height, 225, MUIA_Bitmap_UseFriend, TRUE, MUIA_Bitmap_Bitmap, bitmap_vignette, TAG_DONE);
}


Thanks

Hello Thore,
Thank for your reply.

Yes there are a lot of thing in the Serial line at the moment of this freeze
(I never think to use serial...)

Thank you by advance if you have a clue (even if you don't have...)

Hi,
I'm playing too with MUI Bitmap, contrary to you, I don't have problem to update my Bitmap but my program (and the OS) freezes when I deiconify my program.
Do you do something special to prepare the deiconification of your Bitmap ?
When I remove it, in iconification phase with REMMEMBER, and not readd it during deiconification, it works.

I have tried the InitCHange, ExitChange method, but it freezes, when I do the following in the deiconification

if (DoMethod(redrawGroupe, MUIM_Group_InitChange))
{
DoMethod(redrawGroupe, OM_REMMEMBER, Im_Data_bmp);
DoMethod(redrawGroupe, OM_REMMEMBER, rect2);
DoMethod(redrawGroupe, OM_REMMEMBER, STR_EnCours_Label);
DoMethod(redrawGroupe, OM_REMMEMBER, boutonGroupe);
SetAttrs(Im_Data_bmp, MUIA_Bitmap_Width, 300,MUIA_Bitmap_Height, 225, MUIA_Bitmap_Bitmap, bitmap_vignette, TAG_DONE);
DoMethod(redrawGroupe, OM_ADDMEMBER, Im_Data_bmp);
DoMethod(redrawGroupe, OM_ADDMEMBER, rect2);
DoMethod(redrawGroupe, OM_ADDMEMBER, STR_EnCours_Label);
DoMethod(redrawGroupe, OM_ADDMEMBER, boutonGroupe);
DoMethod(redrawGroupe, MUIM_Group_ExitChange);
}

I tried with or without the SetAttrs => KO
I tried without REMMEMER ADDMEMBER of Im_Data_bmp => no freeze (but no Bitmap)

Thank for your help

Thank to you,
all works !

When I said "for dummy"... ;)

Thank for reply

1) area selection works, great !

2) no succeed to use palette, no colouring difference with paint tool.
Will retry later if I need it, the normal (or advanced) color selection is largely enough for me.

3) For export, I thought about PNG or JPEG format. Because for now, to use the picture on another program, I have to export in ILBM format and reopen it with WarpView to transform it in JPEG or PNG.
Just a suggestion, because it's not a big pain

PS : Protect works.

Now, with selection tip, I will be able to use it more seriously ;)
