![]() ![]() ![]() The decision is based on theĪlpha value of the pixel as read from the Texture. Some pixels without drawing anything at all. In addition to blending, when the Shader is rendering an object it discards canvasBack always has to be drawn first and if the application is purelyįading from one image to another it can leave canvasBack at apha=1.0 (i.e.ĭefault value) and just increase then decrease the alpha of canvasFront Then draw the canvasBack (z=0.2) with alpha=0.9 the result willīe a very faint image on canvasFront and nothing on canvasBack. If you first draw the canvasFront (z=0.1) with alpha=0.1 Which sounds obvious but to give an example if a slideshow tries to blendīetween two images, one drawn in front of the other: You have to draw things on top of other things… However the gpuĭoesn’t take into account the transparency of the pixel when it’sĭeciding if something is nearer or further away, so for blending Gpu found something else nearer to the view point. If the background was drawnįirst then the same pixel might have to be redrawn several times as the Is then less of the background to fill in. Of this it is normally optimal to draw foreground objects first as there Information on how far from the camera each pixel has been drawn. When the gpu is rendering an object there is a depth buffer that holds In the draw() method so that blend is enabled when alpha is set to less than 1.0. Point by mytexture.blend = True In addition to this setting there is a check Setting the blend=True argument when the Texture is created or at a later To be blended with whatever’s behind them. Switched on or off as each Shape is drawn, allowing or preventing the pixels The graphics processor has a global setting to enable blending that is The way that transparency is handled is quite hard to understand. The blending of the pixels with alpha less than 1.0 is controlled by setting theĪlpha value of pixels in a png type image file 3. Transparency of Shapes can be altered by 1.

PicFrame on the Mac is just as easy to use, select a frame, drag and drop your photos in, tweak the border size, give the photos rounded corners, add a color or pattern, resize the adjustable frames and save the photo or share it to Facebook. With 73 adjustable frames, support for up to 9 photos in a single frame, rounded corners and plenty of border patterns, you will always have a unique look. PicFrame helps you combine multiple photos into amazing looking frames that you can save to your computer or share to Facebook Twitter and Flickr. Quickly create collages by dragging and dropping your photos into a customizable frame!
