Member Enumeration Documentation

LoadingHint

enum KItinerary::PdfImage::LoadingHint

Hints for loading image data.

Enumerator
NoHint	Load image data as-is. The default.
AbortOnColorHint	Abort loading when encountering a non black/white pixel, as a shortcut for barcode detection.
ConvertToGrayscaleHint	Convert to QImage::Format_Grayscale8 during loading. More efficient than converting later if all you need is grayscale.

Member Function Documentation

hasObjectId()

bool PdfImage::hasObjectId

(

)

const

Returns whether this image has an object id.

Vector graphic "images" don't have that.

Definition at line 242 of file pdfimage.cpp.

height()

int KItinerary::PdfImage::height

(

)

const

Height of the image in PDF 1/72 dpi coordinates.

image()

QImage PdfImage::image

(

)

const

The source image with display transformations applied.

Definition at line 229 of file pdfimage.cpp.

isVectorImage()

bool PdfImage::isVectorImage

(

)

const

Returns whether this is a raster or vector image.

Definition at line 252 of file pdfimage.cpp.

objectId()

PdfImageRef PdfImage::objectId

(

)

const

PDF-internal unique identifier of this image.

Use this to detect multiple occurrences of the same image in different places, if that reduces e.g. computation cost.

Definition at line 247 of file pdfimage.cpp.

pathElementsCount()

int PdfImage::pathElementsCount

(

)

const

If this is a vector image, this returns the number of vector path elemets.

Definition at line 257 of file pdfimage.cpp.

setLoadingHints()

void PdfImage::setLoadingHints

Sets image loading hints.

Definition at line 224 of file pdfimage.cpp.

sourceHeight()

int PdfImage::sourceHeight

(

)

const

Definition at line 209 of file pdfimage.cpp.

sourceWidth()

int PdfImage::sourceWidth

(

)

const

Width of the source image.

Definition at line 214 of file pdfimage.cpp.

transform()

QTransform PdfImage::transform

(

)

const

Transformation from source image to final size/position on the page.

Values are 1/72 inch.

Definition at line 219 of file pdfimage.cpp.

width()
