Java games rock!


« Posted 2004-09-22 09:03:50 »

if i set a clipping region and then need to reset it to the origin
(whole screen shall be painted), i have to differ between the different device-resolutions.

i could be lazy and choose only a region, whioch covers  the largest screen-resolution (e.g. 200x200). then i wouldnt need
to store the actual height and width of the screen or getting it out of the canvas.
but: is there any performance difference between choosing the suitable clipping region and choosing a much bigger one ?

I can't answer about any performance issues (or any other issues for that matter). But what I usually do is use the Graphics.getClipX()/getClipY()/getClipHeight()/getClipWidth() methods and save those values so I can restore them when I'm done.
