Deprecated. Stores standard system DPI values.
const dxDefaultDPIValues: array[0..7] of Integer = (96, 120, 144, 168, 192, 216, 240, 288);
| Type | Description |
|---|---|
| array[0..7] of Integer |
The array of standard DPI values.
|
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
DevExpress forms and controls define the active scale factor as integer numerator and denominator values.
Example bitmap icon dimensions.
