Hello again,
The beta2 is out with a lot of beta1 bugs fixed (not all yet), and a few more changes too:
Code: Select all
- Added UsePostgreSQLDatabase()
- Changed FillMemory() to FillMemory(*Memory, Size [, Value [, Type]])
- Removed the "UserData" parameter from CustomGradient() and its callback (to fit the other PB callbacks)
- Added #PB_2DDrawing_CustomFilter drawing mode (ImageOutput only)
- Added CustomFilterCallback()
- Added AlphaBlend(Color1, Color2) - blend two 32bit colors
If you missed the Beta1 announcement, read more here:
http://www.purebasic.fr/english/viewtop ... 524#295524
The #PB_2DDrawing_CustomFilter redirects drawing operations to a callback. It can decide how the source color is put over the target color for every pixel. This mode can be combined with #PB_2DDrawing_Gradient. The callback looks like this:
Code: Select all
Procedure FilterCallback(x, y, SourceColor, TargetColor)
ProcedureReturn AlphaBlend(SourceColor, TargetColor) ; this would emulate the #PB_2DDrawing_AlphaBlend mode
EndProcedure
As usual, the beta can be found on your user account.
Have fun

Fabulous! You implemented my idea! I thought you'd ignored it!
Damn I'm proud...

AlphaBlend looks useful for me and the Image bug (Library Viewer) has gone. Excellent!

Freak, thankyou 100 times for adding the CustomFilter drawing mode. I think it will be very useful for a lot of programmers!
I don't know whether you added it because of my suggestion or not, but either way, the main reason I asked for it was for drawing text. Boxes and circles etc. could be drawn with procedures written by the programmer using Plot(), but drawing text and images really requires the CustomFilter system.
However, unfortunately, this can't be done unless the CustomFilter mode is combined with Transparent mode:
Code: Select all
DrawingMode(#PB_2DDrawing_CustomFilter|#PB_2DDrawing_Transparent)
Would that be possible?
Also, there seems to be a problem if the callback procedure takes in the x and y as floats. It only works if they're integers. Is that a bug? Haven't tried it with doubles yet.
Please see about combining CustomFilter and Transparent. But either way, thanks for all the work you've done. For me personally this has been a fantastic upgrade to PB.

WooHoo!
I thought this would take a while, becasue Fred was just talking a few weeks ago about the MySQL licensing disappointment!
Thanks Fred

How does UsePostgreSQLDatabase() connect and access information? ODBC or a native connection? Are there any database changes that go with it? Are we still stuck with limitations like not being able to get a row count and only being able to access rows and columns in order once from row/column 0 to the max?

Same here...
You have to delete the Purebasic directory under "C:\Users\%yourusernamehere%\AppData\Roaming" then it works.
