More instances of <font class="doc-type">TAgg2D</font> can coexist simultaneously and they can be + attached to the same <font class="doc-type">TBitmap</font> surface at the same time. It's sence is in having a different + states of vector engine in one place (each instance can have a different state of coordinates + transformations for example, or anything that can be set up). <font class="doc-type">TAgg2D</font> is not thread safe, so + each thread should own it's own vector engine.<p> + + After attachement (to the <font class="doc-type">TBitmap</font>) the state of the vector engine becomes default. It's due to achieving + the same starting conditions for the drawing routine. So you have to set up the line color, fill rule, transformations, + clipping, etc.<p> + + Since <font class="doc-type">TAgg2D</font> renders on fly directly to the physical surface of <font class="doc-type">TBitmap</font>, the drawing routine + (after attachement) can be performed anytime it is required. It can be outside the OnPaint method + and also outside WM_PAINT windows message. But as well it can be also a part of those painting methods.<p> + + Here is an introductory example of drawing with <font class="doc-type">TAgg2D</font>: + +<blockquote><font class="pas-source"><pre
