Stitch-up

[dodicat]

Just signed up to mediafire, thought I would try it out:

@ dodicat
Can you not find a site with less advertisments?

In create knot, the first For loop, your line;
Alpha = Alpha + 2*PI / SCALING_FACTOR2
to close the knot, should be something like;
Alpha = Alpha + 2*PI / (SCALING_FACTOR2 – 4 )

Now we all await Mr. Redditt's revenge.

[pestery]

Ah, the old glStencilxxx commands. Just had one small problem with the example. GL_BGRA was not defined, but including GL/glext.bi fixed the problem. Cool example by the way :-)

Regarding mediafire, I've been using it for a while and it seems to be pretty good. It's free, seems to be reliable, no time limit on uploaded files and you can upload as much as you want (as far as I know anyway). As Richard said, there is a bit of advertising but I find it doesn't get it the way like is does on some other sites.

[Roland Chastain]

Very nice program !

dodicat, if you want a folder on my little web site, just say it to me !
roland{.}chastain{at}yahoo{.}fr

Else, you could post your examples here. I don't know if there is an english equivalent.

[dodicat]

Thanks for the feedback.

I left a little space, it looks better?

fb23 doesn't need glext.bi , but fb24 does I see.

Roland Chastain, I might take you up on that.
I like your Philosophy bit.
I've just been watching (on the tele), Bentham, Kant and Aristotle's ideas on Justice.

Seemingly we are all living in a Bentham type situation now. But hey, anybody who gets themselves stuffed and preserved and put on public exhibition can't be ALL bad?

[Roland Chastain]

I might take you up on that.

I have learned an english expression this morning. Good !

It could look like this :

stitchup.bas

When you want to me to add or to remove something, just send it to me in an e-mail.

I like your Philosophy bit.

Thanks !

hi dodicat
how did you convert the image to data statements?
btw it runs OK, 64 fps

[dodicat]

Hi srvaldez.
Hope you are feeling a bit better.
I've got a couple of methods, here's one for colour data for every bitmap pixel.
This is the one I used for Stitch-up.
Compile to exe, then drag and drop a bitmap into it.
(You have screen 20 here, so it will do a reasonably large bitmap, say 800 by 600 for example.
You'll get a file two_sprite.bas, which is a runner and contains data.
Mind you, for even 800 X 600 the data is massive.
It might take five seconds to compile two_sprite.bas.
The file size in Kb is bigger than the actual bitmap in Kb, but I suppose this is to be expected, since 10 characters are needed to define each pixel colour.
Here's the file, just follow the instructions when you use it.

Code: Select all

'Data maker
'compile this to .exe
'drag a .bmp file on to the this executable
'it will create two_sprite.bas (somewhere)
'run two_sprite.bas to view the bitmap data and test the conversion.
Screen 20,32
open "two_sprite.bas" for output as #2

Type bitmap_size
    As Integer across,down
End Type

Dim  mybitmap As String =Command(1)

    Dim As Integer w,h
    Open bmp For Binary As #1
    Get #1, 19, w
    Get #1, 23, h
    Close #1
    Return Type<bitmap_size>(w,h)
End Function

Sub load(bmp As String,pixels() As Integer) 'load bitmap into array of point colours
    Bload bmp
    dim count as integer
    dim as string comma=","
    dim as string dash="_"
    Dim temp As bitmap_size=size(bmp)
    Redim pixels(temp.across,temp.down)
    dim max as integer=(1+temp.across)*(1+temp.down)
    For x As Integer=0 To temp.across
        For y As Integer=0 To temp.down
            count=count+1
            pixels(x,y)=Point(x,y) 
            if count=max then
                comma=""
                dash=""
            end if
            print #2,"&H"& hex(point(x,y))&comma;
            if count mod 8=0 then print #2,dash

thank you dodicat :)
yes I am getting better although a bit slow.

@dodicat and Richard

I can't go on mediafire from my apartments ethernet. I'll have to go to the library to download it.
I was putting my programs on mediafire. They allow 2 gigabytes of throughput off each free account a month.

The apartment complex won't allow the site to come up , because lots of the potential downloads have viruses and pirated,copyrighted materials, and they don't want infected or sued.

Where are you guys getting FB 0.24, the NEWS section of the main board still say FB 0.23 ?

[albert]

Back when i first got linux, in the late 90's

I found a method of enlarging small thumbnail jpg's to full screen size without pixelating the picture.

1) load the small pict into GIMP , gausian blur it to 1
2) double the size of the pict.
3) load pict into XView and sharpen to 75 (XView was commercial and redhat 5.0 had permission to use it in their distro, the GIMP sharpen doesn't work too good and neither does ImageMagik sharpen.)
4) load pict into GIMP or ImageMagik and oilify to .5
5) I cant remenber if 4 is the last step or if theres another. but just keep going 1 to 4 or 5 until the image is the size you want.

you might have to resharpen after the oilify, im not sure.
And it might be Gausian blur to .5 and oilify to 1, its one of the two.

but you can take one of those little thumbnail 75x75 jpg's and blow it up to 1024x768 fully clear and no pixelation.

@Albert
Roland Chastain has the file on his site, four posts back.
Just click the link and as by magic you get the code.
Why don't you apply for the job as the appartment software guy, and get rid of silly rules?

Fb24, down at the page bottom.
The 33Mb download includes gcc.

Hello!

I just tried to compile stitchup.bas with FBC 1.02.1. I mean the file from my website, not the file from MediaFire. The file from my website has one more line:

Code: Select all

#include once "GL/glext.bi"

I get errors:

FreeBASIC Compiler - Version 1.02.1 (04-25-2015), built for win32 (32bit)
c:\freebasic\inc\GL\windows\glext.bi(52) error 58: Illegal specification, at parameter 1 (mode) in 'type PFNGLDRAWRANGEELEMENTSPROC as sub(byval mode as GLenum, byval start as GLuint, byval end as GLuint, byval count as GLsizei, byval type as GLenum, byval indices as const any ptr)'
c:\freebasic\inc\GL\windows\glext.bi(53) error 58: Illegal specification, at parameter 1 (target) in 'type PFNGLTEXIMAGE3DPROC as sub(byval target as GLenum, byval level as GLint, byval internalformat as GLint, byval width as GLsizei, byval height as GLsizei, byval depth as GLsizei, byval border as GLint, byval format as GLenum, byval type as GLenum, byval pixels as const any ptr)'
...

I imagine that the problem has already been discussed somewhere, but I found nothing.

Hi Roland!

Maybe you're looking for this: http://www.freebasic.net/forum/viewtopi ... 14&t=19316

I've played around with it a little. stitchup.bas compiles if you add

Code: Select all

#include once "GL/gl.bi"

as first line of the code.

Regards
grindstone

Hello,

looks like the new inc/GL/windows/glext.bi is missing an #include "GL/gl.bi" at its top, that probably got lost somewhere when I made the new OpenGL bindings. #including GL/gl.bi before GL/glext.bi should work as a temporary work-around. But I'll update glext.bi for the next FB release to do it automatically.
