Tips & Tricks / Re: CPU Meter
« Last post by Patrice Terrier on July 08, 2024, 06:16:49 pm »
This is version 2.00.

It has been reworked to match the CPU processor percentage computation used in Windows 11.

On previous Windows 10, they were using "Processor(_Total)\\% Processor Time"

The solution is to use PDH (Performance Data Helper) and the Processor Utility request
nStatus = PdhAddEnglishCounter(cpuQuery, L"\\Processor Information(_Total)\\% Processor Utility", NULL, &cpuTotal);

\\Processor Information(_Total)\\% Processor Utility
  • Description: This counter measures the percentage of processor utility across all processors.
  • Utility: It provides a more detailed and modern view of processor usage, taking into account various factors like the efficiency of processing and modern CPU architectures.
  • Availability: This counter is generally available on newer systems with modern processors. It can give a more accurate representation of CPU utilization in multi-core and hyper-threaded environments.
\\Processor(_Total)\\% Processor Time
  • Description: This counter measures the percentage of time the processor is busy executing a non-idle thread.
  • Utility: It is a more traditional counter that has been available in Windows for a long time. It reflects the CPU load by measuring the active time versus the idle time of the CPU.
  • Availability: This counter is widely available across different versions of Windows and provides a consistent measure of CPU usage.
Note:
The project use TCLib.lib to produce a tiny 29 Kb binary executable.

Eye Candies / BassBox64 (alias BB64) full VS2022 project
« Last post by Patrice Terrier on June 23, 2024, 07:15:47 pm »
BassBox64 (alias BB64)
is a C/C++ VS2022 64-bit version, using a totaly different GUI, with huge size optimization.
The OpenGL visual plugins are still those from the PowerBASIC 32-bit version.



When visual plugins are enabled, press the left or right mouse button to change them.
You can also use the mouse buttons to select a specific image background.

The concept / Tutor_19 "Circular text" (C++ VS2022 GDImage64 tutorial)
« Last post by Patrice Terrier on April 13, 2024, 07:32:58 pm »
About Tutor_19
Its purpose is to create one single or multiple circular text objects to use for logo or animaion.

It uses a new API named ZD_CreateCircularTextBitmap
using 7 parameters:
WCHAR* zText, the unicode string to create the circular text from.
WCHAR* zFont, the unicode string for the font to use (could be a .ttf private font).
long fontSize, the font size height.
long fontSyle, for example FontStyleBold.
long radius, the inner radius of the circular text.
DWORD ColrARGB, the ARGB color to use.
float step, the distance between each character.

The function returns a BITMAP handle that can be used by the ZD_DrawBitmapToCtrl API.

The AngleRotation procedure is using direct call to the GDIPLUS FLAT API to compute the correct rotation angle.

The window itself works in DWM transparent composited mode using the GDImage ZI_DwmEnable API.

Tutor_06,
has been updated to use the latest GDImage64.dll and WinLIFT64.dll, now with Y slider (like in the 32-bit version).

64-bit SDK programming / Webp
« Last post by Patrice Terrier on February 27, 2024, 09:45:02 am »
WebP is a raster graphics file format developed by Google intended as a replacement for JPEG, PNG, and GIF file formats. It supports both lossy and lossless compression, as well as animation and alpha transparency.

The attached C++ VS2022 SDK style source code project is able to convert .webp to .png using direct call to the gdiplus flat API.

The project is provided with a webp image created with the help of AI (ChatGPT 4).

It is a complement to the webm project posted here.
