DynaPDFMBS.RenderPagePicture(PageNum as Integer) as picture

dim pdf as new MyDynaPDFMBS

// For this example you can use a Pro or Enterprise License
pdf.SetLicenseKey "Pro"

// create in memory
call pdf.CreateNewPDF nil

// set import flags
call pdf.SetImportFlags pdf.kifImportAsPage

// open the PDF file
dim f as FolderItem = SpecialFolder.Desktop.Child("test.pdf")
call pdf.OpenImportFile(f, 0, "")

// import all the pages
call pdf.ImportPDFFile(1, 1.0, 1.0)

// and render first page
dim out as Picture = pdf.RenderPagePicture(1)

// display in window
Backdrop = out

Please note that for most cases RenderPageToImage and RenderPDFFile are better choices for rendering. Especially if you plan to compress images later anyway. And you avoid trouble with color matching. For this function to work correct you have to initialize DynaPDF with right color space for screen (Generic RGB on Mac and screen profile for Windows).

The picture size is set to the Cropbox. If no crop box is defined, it uses the media box.

Returns nil on any error.

If you render a lot of pages from the same PDF, consider using DynaPDFRasterizerMBS class as it's faster when you reuse the rasterizer.

Currently not available for Linux Desktop apps.
Requires DynaPDF Pro license.

For pages with orientation of 90 or 270 degree, the plugin will take that into account and swap width/height to have rendered picture have the riuht size.

And you avoid trouble with color matching. For this function to work correct you have to initialize DynaPDF with right color space for screen (Generic RGB on Mac and screen profile for Windows).

The picture is created with the given size. The PDF page is scaled to fit size. You can use the constants kpsFitBest, kpsFitHeight or kpsFitWidth for the DefScale parameter. The matrix allows you to move, rotate or scale the PDF inside the picture.

Returns nil on any error.

If you render a lot of pages from the same PDF, consider using DynaPDFRasterizerMBS class as it's faster when you reuse the rasterizer.

Currently not available for Linux Desktop apps.
Requires DynaPDF Pro license.

If page is rotated, please swap width and height yourself.

PixFmt: pass kpxf* constants like DynaPDFRasterizerMBS.kpxfRGB.
Filter: Pass kcf* constants like DynaPDFMBS.kcfJPEG.
Format: pass kifm* constants like DynaPDFMBS.kifmJPEG.

The page that should be rendered must be closed (Append() or EditPage() open a page and EndPage() closes a page).
If the parameter OutFile is set to nil the image is created in memory. In this case call GetImageBuffer() to retrieve the image buffer and finally FreeImageBuffer() to release it.

The output image size can be calculated in different ways:

• If Resolution is > 0 the image width and height is calculated according to the specified resolution. On a 32 bit machine it is possible to render pages in up to 1200 DPI depending on the page format. Larger resolutions require special techniques like banding to restrict the memory usage. However, no such feature is available in DynaPDF.
• If Width > 0 and if Height == 0 the image height is calculated according to the given width to archive an image with exact proportions.
• If Width == 0 and if Height > 0 then image width is calculated according to the given height to archive an image with exact proportions.
• If Width > 0 and if Height > 0 the image is scaled to the width and height.

• /DynaPDF/DynaPDF Graphics/DynaPDF Graphics
