[Gnoga-list] Unexpected Behavior of Draw_Image
I am getting unexpected results when using Draw_Image with a canvas that has been resized to match the size of the IMG that is being drawn in it. The attached program demonstrates the behavior. Different initial sizes of the canvas can be used by selecting one of the Create calls, and one of the two Draw_Image procedures may be selected. When the canvas' initial size is not the same as the size of the image, the contents of the canvas are not the same as those of the image. If the canvas is created the same size as the image, then the canvas and the image are identical. Possibly this is the correct behavior, but in that case I would like to know how to get a resized canvas to have the same contents as an IMG. I have tested this on Linux with Firefox 119.0.1 and Chromium 119.0.6045.159. --Jeff Carter"Now go away or I shall taunt you a second time."Monty Python and the Holy Gralwith Gnoga.Application.Singleton; with Gnoga.Gui.Element.Canvas.Context_2D; with Gnoga.Gui.Element.Common; with Gnoga.Gui.View; with Gnoga.Gui.Window; procedure Draw_Image_Error is Window : Gnoga.Gui.Window.Window_Type; View: Gnoga.Gui.View.View_Type; Image : Gnoga.Gui.Element.Common.IMG_Type; Canvas : Gnoga.Gui.Element.Canvas.Canvas_Type; Context : Gnoga.Gui.Element.Canvas.Context_2D.Context_2D_Type; begin -- Draw_Image_Error Gnoga.Application.Title (Name => "Demonstrate error in Draw_Image"); Gnoga.Application.HTML_On_Close (HTML => "Draw_Image_Error ended."); Gnoga.Application.Open_URL; Gnoga.Application.Singleton.Initialize (Main_Window => Window); View.Create (Parent => Window); View.Text_Alignment (Value => Gnoga.Gui.Element.Center); Image.Create (Parent => View, URL_Source => "rgb.jpg"); View.New_Line; delay 0.5; Canvas.Create (Parent => View, Width => 1, Height => 1); -- Canvas.Create (Parent => View, Width => 500, Height => 500); -- Canvas.Create (Parent => View, Width => Image.Width, Height => Image.Height); delay 0.5; Canvas.Width (Value => Image.Width); Canvas.Height (Value => Image.Height); Context.Get_Drawing_Context_2D (Canvas => Canvas); Context.Draw_Image (Image => Image, X => 0, Y => 0); -- Context.Draw_Image (Image => Image, X => 0, Y => 0, Width => Image.Width, Height => Image.Height); delay 9.0; Gnoga.Application.Singleton.End_Application; end Draw_Image_Error; draw_image_error.gpr Description: Binary data ___ Gnoga-list mailing list Gnoga-list@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gnoga-list

I realized I hadn't pulled for a while, so I did a pull and now "make all" has errors with the Simple Components. The first I saw was fixed long ago, before GNAT 13 was released, IIRC: In deps/simple_components/atomic-access/ada/gnat-sockets-server.adb, procedure Do_Connect, 'Unchecked_Access needs to be changed to 'Unrestricted_Access. If I fix that, then there are other errors that are not so obvious. It's as if it's a much earlier version of the Simple Components. But that is another issue. I'll look into seeing if I can compile 2.1a and use it to make a reproducer. But basically, I obtained a Pixel_Data_Type from a Canvas/Context and then wrote a BMP file of the image. The resulting image was garbled. For a sufficiently small image you could write a P3 PPM file more easily if you want to try it out. All this is based on the usage of X and Y as indices into a Pixel_Data_Type in procedure Data (Image_Data_Type; Pixel_Data_Type) and function String_To_Pixel_Data, where you find D (X, Y), for example. There's no indication in the spec of Gnoga.Types of the meaning of the two dimensions, but there should be. --Jeff Carter"Now go away or I shall taunt you a second time."Monty Python and the Holy Gral On Thursday, November 16, 2023 at 10:25:39 PM GMT+1, Blady wrote: Hello Jeff, > Le 14 nov. 2023 à 18:35, Jeffrey R.

Well, one chance out of two to be ... wrong. However, I recall having tested the Data procedure and function against Javascript in canva_test.adb.

[Gnoga-list] 2.1a Not Backward Compatible
I note that Gnoga 2.1a is not backward compatible with 1.6a due to the introduction of UXStrings. I had hoped that this would only involve overloaded operations, and that those using String would continue to be available. In addition to littering my code with conversions to UXString, I would have to change any sources I have that use the upper half of Character to UTF-8 encoding, as the spec of UXStrings uses non-ASCII characters in UTF-8 encoding, GNAT's source-based model means that specs are read every time something that uses the pkg is compiled, so any compilation against Gnoga must use UTF-8 encoding. This seems like excess effort for no gain, so I won't be making the transition immediately. However, it appears that 2.1a has resolved the recompilation problem that plagued earlier versions. What was the culprit and its fix? I would like to see the fix applied back to earlier versions if possible. --Jeff Carter"Now go away or I shall taunt you a second time."Monty Python and the Holy Gral___ Gnoga-list mailing list Gnoga-list@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gnoga-list
[Gnoga-list] Selection_Type Value and Apostrophes
Somewhere in the intersection of Gnoga 1.6, GNAT 11.2, and Firefox 94.0 on
Xubuntu 20.10 I have encountered this "feature". If the Value supplied for an
option of a Selection_Type contains an apostrophe ('), the Value function for
that option discards the apostrophe and all characters after it. I'm not sure
if this is expected behavior.

That prevents it dying from adablog and allows it to build the remaining demos and the tutorials. Tutorial 11 also dies because it uses Sqlite; putting a '-' before the call to build tutorials (line 286?) also makes that not fatal.

Hello Jeff, It seems that libsqlite3 is not present or not in view of the linker of your configuration. If so, sqlite3 source codes are present in Gnoga. Just do (in Gnoga folder): $ make sqlite3 Then "make all", the linker should find libsqlite3 in /lib. @Gautier: libsqllite3 should be built by Gnoga makefile automatically if make is launched from a Windows command window.
