#X text 64 389 pix_imageInPlace is slightly different than pix_multiimage.
When you select an image to display with pix_multiimage \, it copies
over the image data to the pix_buffer \, which is then used by pix_texture.
;
#X text 62 451 This is potentially slow if you are trying to change
between a lot of images \, but it doesn't use a lot of texture ram.
;
#X text 62 503 pix_imageInPlace sends all of the image data to texture
RAM when the preload message is received. This means that you cannot
process any of the pixel data \, but it is extremely quick to change
between the various images.;

or less) native color-space. most of the times \, this will probably
be not RGBA but RGB or BGR (on windows machines).;
#X text 48 153 do not worry about this. however \, most of the pix-manips
will only work correctly on RGBA-pixes. if this is the case and you
send it a non-RGBA pixture it will say something like "pix_object cannot
handle gray image".;
#X text 49 226 to avoid this \, you can convert your pix-buff to RGBA
using "pix_rgba". this will be a no-cost operation if the pix_buf already
is in RGBA.;
#X text 36 334 you might notice a significant performance-enhancement
by just turning the [pix_rgba] off (via the toggle). however \, not
[pix_rgba] is expensive but actually the [pix_convolve] (which appears to do
nothing when initialized with "0 0 0 0 1 0 0 0 0". When [pix_rgba]
is "off" \, the [pix_convolve] will be bypassed \, and therefore be
very fast.;
