Understand 'highlight something preferably codeish ' as syntax highlighting.
#Purebasic alphablend 64 Bit#
This bypasses the AlphaBlend function, and so works fine on 64 bit systems. Book 1 - Language Definition Testing File Comments in Inform 7 can be nested inside one another Syntax highlighting is an action applying to one thing. Then call SetDIBits to write the modified bits back to the background bitmap. For Blender 2.9+ (and future versions, Blender 3.0, 4.0 etc.) controlling basic material transparency using a separate opacity ‘map’ or image works exactly the same as it does for Blender 2.

Green_bkg = A * green_circle + B * green_bkgīlue_bkg = A * blue_circle + B * blue_bkg Overview making a simple transparent material where transparency is defined by a separate image, a grey-scale opacity map or black and white opacity mask.

Procedure drawCanvasBackground (canvas) Dim color (1) color (0)RGB (40,40,40) color (1)RGB. Drawback: The main window looses focus if you use the toolwindow. It is easy with normal PB Windows and transparency.
#Purebasic alphablend how to#
What I have done to fix this is to use GetDIBits to load the bitmaps into RAM arrays and then I can do the alpha math myself: Re: 460 Final How to transparent container on canvas gadge.

Then call AlphaBlend with bfn.SourceConstantAlpha = 255 andĪs you say, the problem is this doesn't work on 64 bit systems. Im working on part of the Survival Guide and Im struggling a bit with the alpha channel stuff. The "else" case uses a global value (200) combined with individual alpha values for each pixel (in the 4th byte of the pixel dw), and this is handy for a lot of things.įor example, if you want to place a circular image over an existing "background" bitmap, you can draw the circle on a new square bitmap and assign alpha = 0 for all the pixels outside the circle. Your "if(fIsX64)" case uses a single alpha value (75) for the whole bitmap, and that does seem to work on 64 bit systems. Blitzmax is more complete (including an openCL module), but purebasic generate very nice, ready to patch, ready to. You just set the colors of the regions with alpha values and they are drawn over the background perfectly. ker2x: Sometimes i use PureBasic or BlitzMax. On a side note, for a separate project that I am working on, I am using QT with QPixmap (for background image), QPainter (to draw overlays on QPixmap) and QLabel (to display QPixmap) classes to draw semi-transparent regions on top of a background image and

this draws empty overlaid regions on 64bit machines but looks great on 32bit PCs but it's better than current alternatives on 64bit machines this isn't great, and causes problems on 32bit PCs (if you use it on them also), Now alpha blend objects back to main DCīLENDFUNCTION bfn = // Struct with info for AlphaBlend It doesn't look as good on 64-bit PCs as on 32-bit PCs, but its not too far off:

This is the code I'm currently using, based on Lingzhi Sun's suggestions.
