THPDFPage page-size demo projects

Delphi PageSetup folder 現在依實際輸出尺寸分隔 page-size examples：

LargeSize demonstrates QuadA0, DoubA0, A0, A1, A2, B0+, B0, B1, B2, ANSI-C/D/E, ARCH-C/D/E1/E, Japanese sheet sizes, large photo sizes, and a 1024 x 768 mm UserDefined page.

NormalSize demonstrates A3, Tabloid, Ledger, A4, Letter, A5, B3, B4, B5, medium photo sizes, ANSI-A/B, and ARCH-A/B.

SmallSize demonstrates A6-A10, B6-B10, business-card sizes, ISO 7810 ID/passport sizes, ID photo sizes, and small photo print sizes.

既有 psXXX names 仍是相容 aliases。新程式碼對標準尺寸應優先使用無前綴的 page-size enum values，例如 A0、A2、B2、B3、Tabloid、Ledger、ANSIC、ARCHD、USBC 與 P8R。只有在尺寸未預先定義時才使用 UserDefined

Tabloid is 11 x 17 inches. Ledger is the landscape 17 x 11 inch size; do not treat Ledger as another name for portrait Tabloid.

當實際規格以數字開頭時，photo-size enum names 會使用 P 前綴。例如 P5R 代表使用者可見的 5R photo size

B-series values 遵循既有 HotPDF B4 / B5 慣例，並使用 JIS B dimensions；psB4 與 psB5 仍是支援的 aliases

Example:

program NormalSize;

{$APPTYPE CONSOLE}

uses

SysUtils,

HPDFDoc;

var

  HPDF: THotPDF;

begin

   HPDF:= THotPDF.Create( nil );

   try

       HPDF.AutoLaunch := true;                // PDF file will be shown automatically

       HPDF.FileName := 'NormalSize.pdf';  

       HPDF.PageLayout := plOneColumn; // Set one column viewer mode

       HPDF.BeginDoc;                              // Create PDF file

       HPDF.CurrentPage.Size := A3;                        // Prefer predefined standard sizes

       HPDF.CurrentPage.TextOut(10, 10, 0, 'A3 Size'); // Print text

       HPDF.AddPage;                                          // Add new page

       HPDF.CurrentPage.Size := B3;                        // JIS B3 page size

       HPDF.CurrentPage.TextOut(10, 10, 0, 'B3 Size'); // Print text

       HPDF.AddPage;                                                        // Add new page

       HPDF.CurrentPage.Size := P8R;                      // 8 x 10 inch photo page

       HPDF.CurrentPage.TextOut(10, 10, 0, '8R Photo Size'); // Print text

       HPDF.AddPage;                                                     // Add new page

       HPDF.CurrentPage.Size := Tabloid;                  // 11 x 17 inch Tabloid page size

       HPDF.CurrentPage.TextOut(10, 10, 0, 'Tabloid Size'); // Print text

       HPDF.AddPage;                                                     // Add new page

       HPDF.CurrentPage.Size := Ledger;                   // 17 x 11 inch Ledger page size

       HPDF.CurrentPage.TextOut(10, 10, 0, 'Ledger Size'); // Print text

       HPDF.EndDoc;                                                       // Close PDF file

   finally

       HPDF.Free;

   end;
