BGRABitmap tutorial

[circular]

It's normal. A polyline is not a closed figure. The closed parameter means that the end of the segment is closed. See here :

If you want to draw a closed path, then use DrawPolygonAntialias.

By the way, naming a variable storedSpline does not automatically create a spline. You need to call ComputeClosedSpline. See here :
http://wiki.lazarus.freepascal.org/B...map_tutorial_7

If you feel the tutorial is ambiguous somewhere, please tell me what you suggest to add or change.

Thanks! It works great now.

Don't pay attention to that name. I was reusing that name from another piece of code that did use a spline.

Hello,

I've added a new tutorial about texture mapping :

Enjoy

Hello people,

I've added comments to BGRABitmap source code, so it's easy to browse and hopefully to understand it.

You can have a look in the last zip file (3.7) :
https://sourceforge.net/projects/lazpaint/files/src/

If something is hard to understand, tell me so I'll add more comments.

By the way, LazPaint textures look better, and blur filter is faster (the fast blur is very fast indeed).

Thanks for the update! My Spline Editor project makes good use of the BGRABitmap library. I wouldn't have had such a good looking interface if you hadn't written those tutorials.

cool

I'm looking forward to see your spline editor.

For those interested, I've added lightness shading (like Gouraud). It's on subversion. Here is screenshot.

Hello people,

I've added CanvasBGRA property to TBGRABitmap to allow drawing with functions that work the same as the standard Canvas but with antialiasing and alphablending. The AntialiasingMode is always taken into account and there is an Opacity property added in Pen, Brush and Font.
