Declaration
property LoadToHeight: integer;
Description
Specifies the minimum height for the image when loading.
Set
LoadToHeight and
LoadToWidth to the display size for this image and it will be loaded more quickly when:
- Loading JPEG and
JPEG_Scale=
ioJPEG_AUTOCALC- Loading JPEG2000 and
J2000_Reduce=-1
- Loading
PDF files- Importing
Meta files- Loading
ImageMagick files if
AutoScaleImport=True
Note:
- Set
LoadToHeight and
LoadToWidth to 0 to reset optimized loading
- ImageEn will consider the aspect ratio to ensure both
LoadToHeight and
LoadToWidth exceed the minimum specified values (so the final size will generally be larger than the specified values)
Default: 0
Examples
// Load a JPEG as fast as possible, ensuring width is >= 150 and height >= 100 (while maintaining the aspect ratio)
ImageEnView1.IO.Params.LoadToWidth := 150;
ImageEnView1.IO.Params.LoadToHeight := 100;
ImageEnView1.IO.Params.JPEG_Scale := ioJPEG_AUTOCALC;
ImageEnView1.IO.LoadFromFile('C:\myimage.jpg');
// Load a JPEG2000 image as fast as possible, ensuring width is >= 150 and height >= 100 (while maintaining the aspect ratio)
ImageEnView1.IO.Params.LoadToWidth := 150;
ImageEnView1.IO.Params.LoadToHeight := 100;
ImageEnView1.IO.Params.J2000_Reduce := -1; // auto-calc
ImageEnView1.LoadFromFile('image.jp2');
// Load an SVG at size 2000x1000px
ImageEnView1.IO.Params.AutoScaleImport := True;
ImageEnView1.IO.Params.LoadToWidth := 2000;
ImageEnView1.IO.Params.LoadToHeight := 1000;
ImageEnView1.IO.LoadFromFile( 'D:\SVG\Lion.svg' )
