[Lazarus] FCL-Image question
FCL-Image is quite powerful (although notably slow), it is mostly suitable for my needs. I've got it writing a solid black PNG file just fine with the help of the wiki example, but is it possible to create a memory image with an alpha channel and have it save the PNG as such? I can't manage to find anything in the docs about this possibility. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] TurboPower OnGuard changes
Graeme: Query the date/time value of the '/bin' directory under Linux, or 'C:\Windows' or 'C:\WinNT' under Windows. Then work out how many seconds or milliseconds since say 1980-01-01. You then have a pretty unique value. The chances of somebody else running your software and having installed their OS in the exact same millisecond as somebody else is pretty slim. :-) Is it really accurate to the millisecond?

Right, but what I meant was if someone manages to upload their own PHP file to the lazarus server, they can easily have uploaded a PHP file manager which has the capability of deleting files, etc, without ever needing ssh/ftp (this assumes the attack was done through a vulnerable piece of software, that had write permissions, etc.) I don't think this scenario is extremely likely.

[Lazarus] Loading file into TImageList does not properly scale

them to a TImageList, and then add them to a TListView. The problem I'm
having is that I cannot get the little bugger to scale to 96x96; other than
that the code works. I would imagine that setting the timage's stretch
property to true ought to scale the image to 96x96, but that was not the
case.

imgTextures: TImageList;

bmp.Width := 96;

Re: [Lazarus] Loading file into TImageList does not properly scale
as a relative newbie here (but not to coding in PASCAL), why do you have to convert to BMP? does the existing library (ie: LCL and FPC) code not accept PNG, GIF and similar for these graphic purposes? I could not find a way programatically to load an image into a TImageList from a file. The only function I found was: TImageList.AddMasked(TBitmap,TColor); so I had to convert it to a tbitmap first. The problem I'm having is that I cannot get the little bugger to scale to 96x96; other than that the code works. I would imagine that setting the timage's stretch property to true ought to scale the image to 96x96, but that was not the case. sounds like it looks at the image properties for smaller scale with which to increase via the stretch routine... unlike other stretch routines which also reduce in size to the chosen params...

On a somewhat related note, I'm done trying to develop anything interesting on Linux. After installing ~10 extra random dependencies to build OGL apps, everything's still being a pain. There's basically no libraries to make things 3D, so I was trying out GLScene. First, the actual package itself + demos have sources that are nearly compatible with Linux, but require just a tiny bit of editing (GLLCLViewer to GLViewer, for instance in the uses claus). Found out the hard way that unless the app is built as GTK1, double buffering seems to fail. And after installing the GLScene package, every app that uses glscene wants to rebuild all of glscene before it compiles the stupid demos! And there are a lot of demos that are broken even though they're supposed to work... *Throws in towel*. If anything, I'll stick to 2d on Linux using my favorite little buddy, Andorra 2D.

Re: [Lazarus] FPImage docs?
I don't see how putting it in the footer would be offensive, I like the idea myself.

[Lazarus] Graphics unit and DLLs
So I've been tinkering with DLLs and Lazarus.. and I came across a problem. It won't let me import graphics. If I do uses graphics it says it can't find it. If I include the LCL in the compiler options, it gets an error with other pascal files. If I add graphics as the only compiler option, it'll white 'cause it's not a directory. All I want is my friend, tcanvas :( ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] Graphics unit and DLLs
Compiler options as in:Project - Compiler options . But on second glance, it doesn't appear that that would help anything. Well what you suggested (Project inspector dependencies) seemed to work. It recognized the graphics unit and let me have a tcanvas variable, and the quick compile worked fine, but the build failed with: project1.lpr(201,1) Error: Undefined symbol: WSRegisterCustomImageList project1.lpr(201,1) Error: Undefined symbol: WSRegisterMenuItem project1.lpr(201,1) Error: Undefined symbol: WSRegisterMenu project1.lpr(201,1) Error: Undefined symbol: WSRegisterMainMenu project1.lpr(201,1) Error: Undefined symbol: WSRegisterPopupMenu project1.lpr(201,1) Error: Undefined symbol: WSRegisterDragImageList project1.lpr(201,1) Error: Undefined symbol: WSRegisterControl project1.lpr(201,1) Error: Undefined symbol: WSRegisterWinControl project1.lpr(201,1) Error: Undefined symbol: WSRegisterGraphicControl project1.lpr(201,1) Error: Undefined symbol: WSRegisterCustomControl project1.lpr(201,1) Error: Undefined symbol: WSRegisterScrollingWinControl project1.lpr(201,1) Error: Undefined symbol: WSRegisterScrollBox project1.lpr(201,1) Error: Undefined symbol: WSRegisterCustomFrame project1.lpr(201,1) Error: Undefined symbol: WSRegisterCustomForm project1.lpr(201,1) Error: Undefined symbol: WSRegisterHintWindow project1.lpr(201,1) Fatal: There were 15 errors compiling module, stopping Line 201 is the end of the file end. My memory just caught up with me actually: Haven't others discussed how the LCL doesn't work in DLLs? I'm sure they have, and that's what I seem to be trying to do (even if it's just one lowly tcanvas), so I guess it's doomed for failure.

Normally you add the LCL via the project inspector to your dependencies.
