Improving SRW Sample element UI
Below are the code changes for several improvements to the sirepo SRW sample element UI. View the Github Commit.
- Show/Hide the "Background Color" field unless the "Cutoff Background Noise Ratio" is selected (srw.js):
function updateSampleFields(item) {
//...
// hide the sample.backgroundColor field unless sample.cutoffBackgroundNoise has a non-zero value
panelState.showField('sample', 'backgroundColor', item.cutoffBackgroundNoise);
}
// call the updateSampleFields() method anytime one of the sample fields below are updated
beamlineService.watchBeamlineField(
$scope, 'sample',
['cropArea', 'tileImage', 'rotateAngle', 'cutoffBackgroundNoise'],
updateSampleFields);- Add range validation to the "Cutoff Background Noise Ratio" field, valid values are between 0 and 1 (srw-schema.js):
// field: [label, type, default-value, help-text, min value, max value]
"cutoffBackgroundNoise": ["Cutoff Background Noise Ratio", "Float", 0.5, "The ratio for cutoff the background noise (between 0 and 1)", 0, 1], - Add a new field which will display the sample preview image (srw.js):
// add a custom editor for the OutputImageFormat type (which is also an enum in the schema).
// this will call the angularjs directive samplePreview
SIREPO.appFieldEditors += [
// ...
'<div data-ng-switch-when="OutputImageFormat">',
'<div data-sample-preview=""></div>',
'</div>',Much of the former imageFileField directive is repurposed into the samplePreview directive.
