dxDefaultDPIValues Constant

Stores standard system DPI values.

Declaration

const dxDefaultDPIValues: array[0..7] of Integer = (96, 120, 144, 168, 192, 216, 240, 288);

Returns

Type	Description
array[0..7] of Integer	The array of standard DPI values.

Remarks

All DPI values defined in the dxDefaultDPIValues global constant correspond to the following scale factor values:

DPI Value	Scale Factor[1]	Icon Pixel Dimensions[2]
96 (base)	100%	16x16
120	125%	20x20
144	150%	24x24
168	175%	28x28
192	200%	32x32
216	225%	36x36
240	250%	40x40
288	300%	48x48

TdxForm.UpdateImageLists and TdxCustomForm.UpdateImageLists procedures use the dxDefaultDPIValues global constant to switch between multiple bitmap sets designed for different target DPI values.

Tip

This image list replacement technique is deprecated. We recommend that you use only SVG images as UI icons in projects that target multi-monitor mixed-DPI environments.

Footnotes

1. DevExpress forms and controls define the active scale factor as integer numerator and denominator values.

2. Example bitmap icon dimensions.
