Anybody want to collaborate to create a library for Bitmap Effects?

[Rafael_Sol_Maker]

Good job! Well, I known right now three libraries that works with Bitmaps:

- PRCoders' PRFilter (in portuguese, I love this one!)

- Glitchfinder and Untra's Additional Bitmap Methods (source code avaliable!)

- KGC's KGC_BitmapExtension (in japanese, and worked on Ace too!)

Maybe there's other that I don't remember, with a different set of effects, made for VX, but I don't remember anything about. A good point to start is to do a DLL that does something different and entirely new to Bitmaps.

 

[Rafael_Sol_Maker]

Sorry for the double post, but... Have you dropped this project? I think a library to help to draw geometry would be a good idea, we already have some that apply filters.

Oh, and wait... We got a new bitmap manipulating library to put in my list!

- Copern's Bitmap Color Functions (already good and I hope it will be improved soon).

See ya!

Just letting you all know, I am still working on this. I've converted much of my code to a dll, and am working on making awesome effects such as rotation blur, radial blur, whirl blur, and a bulge effect. All I have to do now is convert them over to the dll (they take at least a minute each when written in pure ruby). I also made several other effects such as colorize, tint, grayscale, and I'm working on pixelize at the moment.

You might be interested in the RPG Maker VX Ace DLL SDK I'm working on. I noticed that the RGSS301.dll file exports some functions and they might be of use in a custom DLL file. One export that's really interesting is the RGSSEval function. Basically you can run RUBY code inside your custom DLL with it.

If you don't believe me try this script in RPG Maker:

RGSS_Test=Win32API.new('System\\RGSS301.dll','RGSSEval','P','')RGSS_Test.call("puts \"whoa!\"")The console will output "whoa!".

It's a bit odd because the RGSS301.dll functions seemed to be wrapped in a Proc.new{<function>}.call so you can alter an existing local variable but you can't create a new one (if that makes sense).

The really cool thing is that your custom DLL be set up to automatically monkey patch your RUBY code. All you have to do is add the line: DL.dlopen('<dll name>') and everything is setup for the end user.

I've throw together a quick example. Put the BitmapFuncs.dll file in the same directory as the Game.exe file. Add the line DL.dlopen('BitmapFuncs.dll') to initialise the dll. It will automagically add an Invert method to the Bitmap class to invert a bitmap.

You can download the example with source code from here.

Edit: Tidy up some spelling.

That looks really interesting. Do you know if that kind of thing would work for the earlier RPG Makers too, or if it's new in VXA?

I downloaded the RPG Maker XP RTP and it looks like it exports the RGSSEval function as well. Try the script in my previous post, substituting the System\\RGSS301.dll for RGSS102E.dll or RGSS104E.dll to see if the format is the same. It will either work or crash.

The only difference as far as the SDK is concerned is that the XP run-time doesn't export the RGSSGetStringUTF16 and RGSSSetStringUTF16 functions. So as long as you comment out the code for those functions it should work (as long as the format is the same for the other functions).

By the way I've started adding my own functions. You may be interested in a convolution matrix (filter kernel) function. Basically it's the foundation of several filters. It inputs a 3x3 matrix which tells the filter how to sample each pixel. Here's the code:

#define RGSSApi extern "C" __declspec(dllexport)typedef struct { unsigned char red; unsigned char green; unsigned char blue; unsigned char alpha;} RGSSRGBA;typedef struct{ DWORD unk1; DWORD unk2; BITMAPINFOHEADER *infoheader; RGSSRGBA *firstRow; RGSSRGBA *lastRow;} RGSSBMINFO; typedef struct{ DWORD unk1; DWORD unk2; RGSSBMINFO *bminfo;} BITMAPSTRUCT; typedef struct{ DWORD flags; DWORD klass; void (*dmark) (void*); void (*dfree) (void*); BITMAPSTRUCT *bm;} RGSSBITMAP;RGSSApi bool Filter33(unsigned int object, int _11, int _12, int _13, int _21, int _22, int _23, int _31, int _32, int _33, int scale){ #pragma warning (disable:4312) RGSSBMINFO *bitmap = ((RGSSBITMAP*)(object<<1))->bm->bminfo; #pragma warning (default:4312) long width, height; RGSSRGBA *row; RGSSRGBA *rowcopy; long x, y; float red,green,blue; int xm,xp,ym,yp; if(!bitmap) return false; width = bitmap->infoheader->biWidth; height = bitmap->infoheader->biHeight; rowcopy=new RGSSRGBA[width*height]; row = bitmap->lastRow; RGSSRGBA *rowcopyOffset=rowcopy; memcpy(rowcopy,row,width*height*4); if(scale==0) scale=1; for ( y = 0; y < height; y++) { for ( x = 0; x < width; x++) { if(x>0) xm=-1; else xm=0; if(x<width) xp=1; else xp=0; if(y>0) ym=-width; else ym=0; if(y<height) yp=width; else yp=0; red=(float)rowcopyOffset->red*_22; red+=(rowcopyOffset+ym+xm)->red*_11; red+=(rowcopyOffset+ym)->red*_12; red+=(rowcopyOffset+ym+xp)->red*_13; red+=(rowcopyOffset+xm)->red*_21; red+=(rowcopyOffset+xp)->red*_23; red+=(rowcopyOffset+yp+xm)->red*_31; red+=(rowcopyOffset+yp)->red*_32; red+=(rowcopyOffset+yp+xp)->red*_33; red = red/scale; green=(float)rowcopyOffset->green*_22; green+=(rowcopyOffset+ym+xm)->green*_11; green+=(rowcopyOffset+ym)->green*_12; green+=(rowcopyOffset+ym+xp)->green*_13; green+=(rowcopyOffset+xm)->green*_21; green+=(rowcopyOffset+xp)->green*_23; green+=(rowcopyOffset+yp+xm)->green*_31; green+=(rowcopyOffset+yp)->green*_32; green+=(rowcopyOffset+yp+xp)->green*_33; green = green/scale; blue=(float)rowcopyOffset->blue*_22; blue+=(rowcopyOffset+ym+xm)->blue*_11; blue+=(rowcopyOffset+ym)->blue*_12; blue+=(rowcopyOffset+ym+xp)->blue*_13; blue+=(rowcopyOffset+xm)->blue*_21; blue+=(rowcopyOffset+xp)->blue*_23; blue+=(rowcopyOffset+yp+xm)->blue*_31; blue+=(rowcopyOffset+yp)->blue*_32; blue+=(rowcopyOffset+yp+xp)->blue*_33; blue = blue/scale; row->red=(unsigned char)min(255,max(0,red)); row->green=(unsigned char)min(255,max(0,green)); row->blue=(unsigned char)min(255,max(0,blue)); row++; rowcopyOffset++; } } delete[]rowcopy; return true;}To blur you use Filter33(bitmap_object_id,0,1,0,1,1,1,0,1,0,5)

To blur more use Filter33(bitmap_object_id,1,1,1,1,1,1,1,1,1,9)

To sharpen use Filter33(bitmap_object_id,0,-1,0,-1,5,-1,0,-1,0,1)

To sharpen more use Filter33(bitmap_object,-1,-1,-1,-1,9,-1,-1,-1,-1,1)

To detect edges use Filter33(bitmap_object,0,-1,0,-1,4,-1,0,-1,0,1)

To emboss use Filter33(bitmap_object,-2,-1,0,-1,1,1,0,1,2,1)

As you can see it's a very handy filter to have.

Here's a little something I'm playing around with:

 

[ThallionDarkshine]

That looks pretty sweet. I'll post my bitmap effect code when I get home from school (I've got a radial blur algorithm that's pretty awesome). And I like the use of memcopy. I totally didn't know that function existed. And now that you've done that filter, I'll try to mod it to make it work with kernels of any size.

Edit - Here's my edit of your convolution kernel code to use kernels of any size.

I see you've been working hard.

I've decided to set up a git repository for the library. Is it OK if I add your code to the library?

You can browse (and fork) the library here.

You can download the latest binary file from here.

Sure, this is a good time for me to start using GitHub (my brother constantly tries to force me to start using it).

Edit - Your transform function looks pretty good, except for the fact that it works backwards, basically reversing the transformation that it takes in. And you should make the parameters for the matrix floats and after you take them in divide each by another argument so you can have decimal values.

Edit - And a little side note: be sure to build the dll with visual studio, as dlls built with mingw don't work on XP professional because of the enhanced security settings.
